The side door of a garage is the most quietly ignored opening on most homes. It sits behind the house, out of sight from the street, and it is often fitted with the same tired keyed deadbolt that shipped with the door decades ago. Burglars know exactly how that plays out, because a spare key under a mat or a hidden keyhole is the oldest shortcut in the book.
A keypad lock removes that shortcut entirely. You hand out a PIN instead of a key, and you can change or delete that PIN whenever you want without a locksmith visit. On a garage side door that also means you can give a contractor, a dog walker or a housekeeper their own code and revoke it the same evening.
We spent weeks putting ten of the best keypad locks for garage side doors through their specifications, install requirements and owner feedback, and the results surprised us in one way: the search results are full of garage door opener keypads, which are the wrong product for this job entirely. Below we sort out that confusion first, then rank the ten locks that actually secure a walk-in door.
If you are also rebuilding the door itself, start with our guides to the best insulated garage doors and the best garage doors tested, because the door spec decides which locks will physically fit.

1. Schlage BE365 Camelot Keypad Deadbolt – Best Overall
Schlage Electronic Keypad Deadbolt Lock, Camelot Trim, Satin Nickel
Grade 2 / AAA certified
Up to 19 user codes
9V battery, up to 2 years
Outside escutcheon -35C to 66C
Pros
- Grade 2 / AAA certified metal construction
- Illuminated silicone-coated numbers for night entry
- Screwdriver-only install over an existing deadbolt
- Low-battery indicator and up to 2 years of 9V life
- Physical key backup included
Cons
- Runs on a single 9V battery rather than AA cells
- Interior escutcheon has a narrower temperature range than the outside unit
There is a reason Schlage dominates garage side door conversations in owner forums. On the Garage Journal forum, owners running keypad deadbolts on exterior doors consistently point to Schlage as the brand they would buy again, and one commenter describes them as hard to beat for the money once you compare shopped-around alternatives.
The BE365 arrives with two codes already programmed, which means it opens and works the day it arrives. Add codes for family, a neighbour with a spare set of tools, or whoever maintains the property. The silicone-coated numbers illuminate when pressed, so typing a PIN in the dark with a headlamp on the driveway is not a guessing game.
Grade 2 / AAA certification is the detail that separated this lock from most of the list. For a door that many people never walk past, it is the highest certification level any of these off-the-shelf residential locks carried, and it comes with a limited lifetime mechanical and finish warranty. Electronics are covered for three years.
The temperature range is genuinely wide on the outside escutcheon, from -35C to 66C, which matters in an unheated garage where the interior unit sees a narrower band. The keypad lock is keypad driven in practice even though the listing lists app control, and there is no network radio draining the battery.
Why it works on a garage side door
It replaces an existing deadbolt with a screwdriver and no hardwiring, so a standard steel or insulated man door with a pre-drilled hole is a ten-minute job. Two backup keys come in the box, which means a dead battery never locks out the family.
For anyone who wants their front door and garage door on the same key, the Schlage keyway is the one to standardise on, because most Schlage cylinders can be matched to it.
Where it falls short
The single 9V battery is the recurring complaint. It is a cell that many people do not keep a spare of, and it is easy to forget that the lock needs one rather than four AA cells.
Check your door thickness before buying. The fit is tight at the extremes, and a thick insulated entry door with a deep reveal can need an extended spindle or a thicker bolt that is not in the box.
2. Kwikset 955PML Pembroke Keypad Lever – Best Value
Kwikset 955PML-11PS Pembroke Lever Commercial Grade Electronic Smartcode Lever Lock with SmartKey Venetian Bronze Finish
Grade 2 / BHMA AAA certified
Up to 30 user codes
Single 9V battery
Three locking modes
Pros
- Commercial Grade 2 / BHMA AAA certification
- Keypad mounted at the handle so it is easy to reach
- Up to 30 codes plus SmartKey rekeying without a locksmith
- Reversible lever for either door handing
- Emergency egress opens from inside whether locked or not
Cons
- Bolt holes can end up tilted after tightening
- Strike plate can sit off-centre and need jamb trimming
- Runs on a 9V battery and included cell has arrived dead for some buyers
A lever makes more sense than a deadbolt on a lot of garage side doors, especially steel ones where a deadbolt can bind against the frame if the door is not perfectly aligned. The 955PML puts the keypad right where your hand already goes, at the handle.
That layout is the quiet advantage. Owners with aging hands or a full grip of tools can feel for the illuminated buttons instead of reaching blindly for a separate keypad. The tap-to-light buttons wake on touch, so you do not have to find the lock in the dark first.
Thirty codes is more capacity than most families will ever use, which leaves room for seasonal help or a rental scenario. Three locking modes cover the range: auto-lock requiring a code or key, passage mode that stays unlocked for a party, and disabled passage that always demands a code.
SmartKey is the other reason this one stands out. You can rekey the cylinder to match an existing house key yourself in seconds, without a locksmith, which answers the most common key-management question on garage door forums.
Why it works on a garage side door
Emergency egress operation means the door opens from the inside whether it is locked or not, so nobody can get trapped in an unheated garage. The reversible lever means one part number covers both door handings.
Reports of battery life around two years between changes are common among owners, which for an interior-facing garage door is a low-maintenance proposition.
Where it falls short
Installation is where the complaints cluster. Reviewers report bolt holes finishing slightly tilted, strike plates sitting off-centre and needing jamb trimming, and instructions for the hidden set screws that leave people hunting for a missing screw.
Note the battery type carefully. The listing suggests AA cells in places, but the lock runs on a single 9V, and some buyers received a battery that was already flat.
3. TEEHO TE001 Keypad Deadbolt – Top Rated
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
ANSI Grade 3, IP54 weather resistance
20 codes plus one-time guest code
4 AA up to 365 days
Auto-lock 10-99 seconds
Pros
- Highest owner rating in this group with the largest review base
- 20 user codes plus a one-time guest code that deletes itself
- Auto-lock timer adjustable from 10 to 99 seconds
- Four AA batteries rated up to 365 days with a low-battery indicator
- IP54 weather resistance for an uncovered door
Cons
- Fits only 2-1/8 inch holes and will not accept a 38mm bore
- Batteries are not included
- Must be reset before first use to detect door handing
The TE001 carries the highest owner rating in this roundup and, at more than ten thousand reviews, the largest base of real-world feedback behind it. That combination of score and volume is why it takes the TOP RATED badge rather than one of the higher-spec but less-proven locks.
For a garage side door the practical draws are clear. Twenty permanent codes plus a single-use guest code that deletes itself after entry covers contractors and short-term helpers without leaving live credentials behind. Vacation mode disables every code except the master, so you can hand the property over safely.
The auto-lock timer is the feature owners mention most. Set it anywhere from 10 to 99 seconds after the door closes and there is no way to walk away from an unlocked garage door, which is one of the most common ways side doors get found open.
IP54 weather resistance and aluminium alloy construction suit a door with no overhang. Four AA batteries are rated at up to 365 days, and a red indicator lights below 15 percent charge.
Why it works on a garage side door
Installation needs only a screwdriver and fits standard 2-1/8 inch deadbolt holes. The lock auto-detects door handing after a reset, so there is no manual handing screw to set wrong on an unfamiliar door.
Wrong-entry limits add a layer of delay after repeated failed codes, which slows down the brute-force approach that keypad-only doors are otherwise exposed to.
Where it falls short
It fits 2-1/8 inch holes only and will not work in a 38mm bore. On a garage man door that already has a deadbolt, measure first, because the retrofit is not universal.
Two small annoyances: batteries are not included, and the anti-peeping and mode features add programming steps that some owners find fiddly on first setup.
4. Veise KS02A Fingerprint Keypad Deadbolt – Four Ways In
Veise KS02A Fingerprint Door Lock, Keypad Deadbolt, Matte Black
Fingerprint, keypad, key and one-time code
20 fingerprints and 20 passwords
Grade 3 / BHMA, IP54
4 AA up to 365+ days
Pros
- Four ways in including 0.2-second fingerprint reading
- Stores 20 fingerprints and 20 passwords on the lock itself
- All-metal zinc alloy body rated Grade 3 / BHMA and IP54
- Encrypted local storage with no app dependency
- Roughly 15-minute screwdriver-only install
Cons
- Fits only 2-1/8 inch holes and up to 2 inch door thickness
- Front and back panels must be perfectly vertical or the install is misaligned
- Deadbolt only with no lever handle in the box
Fingerprint entry changes the daily routine for a garage side door. Nobody types a PIN holding a recycling bin, a bike, or a bag of groceries, and that is where fingerprint locks earn their keep on a door that gets used dozens of times a week.
The KS02A stores up to 20 fingerprints on an on-device chip and reads them in about 0.2 seconds. Reviewers repeatedly note that the reader self-learns over time, so a slightly grubby finger that was refused on day one tends to work reliably by week three.
Two backup mechanical keys ship in the box, so fingerprint failure in heavy rain never means a locked-out family. A one-time guest code can be issued to a contractor and it deletes itself after a single use.
One detail worth knowing: credentials are encrypted and stored locally on the lock. There is no app, no account and no radio, so there is nothing to hack remotely and nothing to drain the batteries.
Why it works on a garage side door
Operating range is -31F to 158F and the body carries IP54 waterproofing, which covers the cold-storage-garage case that flattens cheaper plastic locks. The anti-peeping function lets you disguise your real PIN inside a longer string of digits.
Auto-lock in 10 to 99 seconds plus one-touch locking by holding any key for two seconds closes the two most common failure modes on a busy side door.
Where it falls short
Fit is limited to 2-1/8 inch holes and door thicknesses from 1-3/8 inch up to 2 inch. A thicker insulated entry door will not take it without additional parts.
The panels must be mounted perfectly vertical, which is the single most common install complaint. On a warped steel door, expect to spend time shimming rather than drilling. The sensor and keypad also need wiping down in bad weather to stay responsive.
5. Veise RZ-A Keypad Deadbolt – Best Budget Deadbolt
Veise RZ-A Electronic Keypad Deadbolt Door Lock, Matte Black
20 codes plus one-time password
Grade 3 zinc alloy, 200000+ cycles
IP54, -35F to 160F
4 AA up to 12 months
Pros
- Feature set usually reserved for locks costing several times more
- Ten-minute install and about five minutes of programming
- Lockout for 3 minutes after 10 failed attempts
- Backlit keypad with clear locked and unlocked indicator lights
- Vacation mode with a tamper alarm on inside opening
Cons
- Bore hole may need enlarging to fit an existing standard deadbolt
- Mounting bolts can be overtightened and bind the mechanism
- Motor can lack force to fully throw the bolt on some doors
The RZ-A is the pick if you want a proper keypad deadbolt without spending serious money. Reviewers describe it as the best value in the category, and the feature list reads like a lock priced well above it.
Security details are unusually well stated. The zinc alloy cylinder is BHMA and ANSI Grade 3 tested and rated past 200000 cycles, which is a durability number most sellers in this price range simply do not publish.
The anti-peeping password accepts random digits before or after your real code, so a shoulder-surfer watching you enter one code learns nothing usable. After ten wrong attempts the keypad locks itself for three minutes, which turns a one-guess-per-second attack into a very slow one.
Vacation mode disables all codes except the master and sounds an alarm if the door is opened manually from inside. Silent mode mutes the keypad beeps but keeps the low-battery and security alerts, which is what you want on a door near a bedroom wall.
Why it works on a garage side door
IP54 weatherproofing and a -35F to 160F operating range cover the wide temperature swing in an unheated garage. Four AA batteries give up to 12 months of daily use with a backlit low-battery alert.
The screwdriver-only install fits doors from 1-3/8 inch up to 2 inch thick in either handing, which covers most standard man doors without modification.
Where it falls short
The negatives here are mechanical rather than electronic. Owners report needing to enlarge the bore on some existing deadbolts, a bolt that installs crooked if the hole is not reamed evenly, and an overtightened mounting bolt that binds the mechanism.
A few have a motor that struggles to fully throw the bolt, particularly on a door that does not swing perfectly. Check the bolt throws smoothly by hand before you program any codes.
6. iulock IU-30 Keypad and Key Lock – Best for Thick Doors
iulock Keypad & Key Smart Door Lock, 50 User Codes, Waterproof, Auto Lock – Matte Black
Up to 50 codes of 1-15 digits
IP65, -22F to 176F
Fits doors 1-3/8 to 2-1/2 inch thick
Type-C USB backup power
Pros
- Handles doors up to 2-1/2 inch thick
- the thickest in this group
- Highest code capacity here with 50 programmable codes of 1-15 digits
- Detachable silicone grip is easy to turn with wet or gloved hands
- IP65 weather resistance for an unshielded door
- Type-C USB backup power plus 4 AAA batteries
Cons
- Master code is printed only in tiny text on the box
- Sealing gaskets and the interior connector cable are awkward to fit
- Every function must be operated from outside the door
Thick doors are where most retrofit keypad locks quit. The iulock IU-30 fits doors from 1-3/8 inch up to 2-1/2 inch thick, with an adjustable latch that covers both 2-3/8 inch and 2-3/4 inch backsets. That range includes the 2.5 inch exterior doors that owners on lock forums ask about specifically.
The detachable silicone grip is the feature nobody expects to care about and then relies on daily. A knob lock you can actually turn with wet hands, gloves on, or a bucket hooked over your arm behaves very differently from a bare metal knob in the rain.
Code capacity is the joint highest here. Up to 50 codes of one to fifteen digits each, plus a master code, leaves room for every contractor who has ever touched the property without a shared code being guessed or copied.
Unlock dwell time is configurable up to 12 hours, which turns the same lock into a gate or shed hasp for yard work and outbuildings. IP65 rating and a -22F to 176F range cover serious winter conditions.
Why it works on a garage side door
A keypad plus key cylinder gives you a mechanical fallback if the four AAA batteries ever fail, and the Type-C backup power terminal means a USB power bank can wake the lock without a 9V.
Rubber rosette seals on the interior side help keep drafts and insects out of a garage that is rarely conditioned.
Where it falls short
The master code is printed in very small text on the box and is not in the instructions, so keep the packaging somewhere safe until the lock is fully programmed.
Every function, including passage mode, is operated from outside the door, which is inconvenient if you need to disable locking for a gathering. The included keys also feel cheap compared with the rest of the unit.
7. BOTHSTAR YJ20 Keypad Door Knob – Best for Sheds and Outbuildings
BOTHSTAR Keypad Door Knob with Key,Keyless Entry Door Lock, Code Locks Door Knob, Auto Lock,50 User Code, for Home,Office,Hotel,Bedroom,Garage,Not Deadbolt
50 codes of 4-15 digits
Key cylinder backup
IP65 weather resistance
Fits doors to 2-1/2 inch thick
Pros
- 50 user codes plus a master code with 4-15 digit flexibility
- Knob format needs only a single bore
- Backlit keypad for dark entries at a shed or garage
- IP65 weather resistance
- Type-C USB backup power and a low battery alarm
Cons
- A knob gives a smaller security footprint than a deadbolt
- Auto-lock has to be re-timed after a code is entered
- Fewer documented warranty terms than the major brands
This one earns its place because garage side doors are not the only thing a keypad lock gets used for. The same keypad logic works on a shed, a storage outbuilding or a detached workshop, and the BOTHSTAR knob is the simplest way to add code entry to a door that has nothing but a knob on it.
A knob needs a single bore, so installation on a plain door is faster and simpler than fitting a deadbolt. The adjustable latch covers 2-3/8 inch and 2-3/4 inch backsets, and the unit fits doors from 1-3/8 inch through 2-1/2 inch thick.
Fifty codes with a master code, each between four and fifteen digits, is generous. Visitor mode handles the case where lots of people are entering and leaving, silent mode cuts the beeps, and password disguise protects a code entered in view of somebody else.
IP65 weather resistance is appropriate for a shed door that gets driven rain from one side for years.
Why it works on a garage side door
A key cylinder backup sits behind the keypad, so a flat battery is an inconvenience rather than a lockout. Type-C backup power adds a second fallback layer for anyone who would rather not keep spare cells.
Auto-lock and a backlit keypad mean the door behaves like a proper entrance rather than an afterthought.
Where it falls short
Be honest about the security difference. A knob offers a smaller security footprint than a deadbolt, so on the actual walk-in garage door we would put a deadbolt on it. Save the knob for outbuildings and secondary spaces.
Operating temperature extremes are not published, which is a fair concern in an unheated garage in a cold climate.
8. Zowill DK01-L Keypad Deadbolt with Handles – Best All-in-One Set
Zowill Keyless Entry Keypad Deadbolt Lock with Handles, Matte Black
Deadbolt plus two lever handles
20 codes plus one-time code
Grade 3, 100000-cycle tested
IP54 weatherproof
Pros
- Only set here that includes a keypad deadbolt and two lever handles in one box
- 20 codes plus a one-time code and two physical keys
- About 20 minutes to install with simple programming
- ANSI Grade 3 and tested to 100000 usage cycles
- Clean look that suits a side entry door
Cons
- Hold-to-lock button processes slowly compared with older keypads
- Deadbolt runs a visible motor cycle before throwing
- Small reset key is easy to lose
Most exterior doors have a deadbolt above and a handle below. This set replaces both at once, which saves a second hole, a second lever and a trip to the hardware store when you realise the old handle finish does not match.
The deadbolt is the security element and the two lever handles are the daily-use element. Owners like the quiet, smooth bolt throw and report that the design looks clean enough that it does not cheapen the appearance of a side entry.
ANSI Grade 3 certification with 100000 usage cycles and 2000N appearance pressure resistance is a defensible durability claim for an exposed door. Four AA batteries are rated at over a year, with a low battery alert to warn you first.
Anti-peeping password, mute mode and vacation mode round out the programming options, and IP54 weatherproofing covers a door without an overhang.
Why it works on a garage side door
If your existing door has a deadbolt and a handle, or you want both, this solves the whole lock in one purchase. That also keeps the finish consistent across the door rather than mixing a satin knob with a black deadbolt.
Two keys come with the deadbolt, so there is still a mechanical way in when the batteries die.
Where it falls short
The one-touch lock button must be held and processes slowly compared with older keypad locks. The deadbolt also runs a visible motor cycle before it throws or retracts, so it feels mechanical in a way that some owners do not like.
The connector between the two halves must seat fully or the unit stays dead, and the reset key is small enough to lose.
9. Megaflint Mechanical Keypad Deadbolt – Best No-Battery Option
Megaflint Keyless Entry Door Lock Deadbolt Keypad Mechanical Stainless Steel (Pass Code or Key) 100% Mechanical, No Electronic
100 percent mechanical, no battery
304 stainless steel deadbolt
4-8 digit code, 8000+ combinations
Fits doors 1.38-1.96 inch thick
Pros
- No batteries and no electronics means no dead-battery lockout ever
- 304 stainless steel with anti-corrosion treatment
- Combines a deadbolt with a working security key
- Large knob is easy to operate while carrying things
- Code changes by hand by swapping pin adapters
Cons
- Does not auto-lock
- the knob must be turned each time
- Handle direction is reversed from most locks
- Wider faceplate can require chiselling the door or jamb
This is the outlier in the roundup, and the reason it is here is simple: it has no battery. For an unheated garage in a cold climate, that removes the single most common failure mode of every other lock on this list, along with any need to keep spare cells.
It is also genuinely mechanical rather than a battery-powered lock dressed up. Tumbler pins give over 8000 possible combinations from a four to eight digit code, the code works in any order so muscle memory settles in fast, and there is nothing electronic to fail.
Owners report the 304 stainless steel holding its finish through two winters of outdoor exposure without dulling, and the surface treatment is stated as far more corrosion resistant than zinc. The wear-free keypad leaves no digit impressions behind for anyone to study.
It also upgrades a door. On a plain knob door with no deadbolt at all, this converts it into a genuine deadbolt door, which is exactly the situation on a lot of older garage man doors.
Why it works on a garage side door
No battery means no cold-weather capacity loss, no low-battery warning to ignore and no emergency jump start procedure to forget. It opens with a passcode, a key, or both.
Fits doors from 1.38 to 1.96 inch thick with a bore between 1-15/16 inch and 2-1/8 inch, in either handing and either opening direction.
Where it falls short
It does not lock automatically. You turn the knob every time, and on a garage side door that is the whole reason you wanted a keypad in the first place.
The handle direction is reversed from most locks, which catches people out, and the wider faceplate usually means chiselling the door or jamb. The mechanism can also need lubricating after about a year.
10. Kwikset 917HFL Halifax Keypad Lever – Best for SmartKey Rekeying
Kwikset SmartCode 917 Contemporary Electronic Deadbolt with Halifax Handle
BHMA AAA certified
Up to 30 codes plus one-time codes
9V battery included, up to 3 years
No wireless capability
Pros
- SmartKey rekeys the lock to an existing house key in seconds
- No app or WiFi means nothing to hack and no radio draining the battery
- Battery can be changed without removing the lock from the door
- Physical key backup included
- Reversible Halifax lever fits either handing
Cons
- Requires 5.5 inch centre-to-centre knob-to-deadbolt spacing
- Handle screw can loosen over time with temperature changes
- Interior battery cover is a tight fit
The most common thread running through garage door owner discussions is key management. People want one key for the front door and the garage side door, and SmartKey is the mechanism that makes it happen without a locksmith visit.
That is the whole appeal of the 917HFL. Owners who deliberately avoided app-connected locks rate it highly for being simple, and several use it on garage or carport storage doors. One owner reports it surviving a Canadian winter, which is useful reassurance for anyone installing one in an unheated space.
Thirty user codes plus optional one-time codes, three locking modes and BHMA AAA certification make this a credible Grade-level lock rather than a novelty. A 9V battery is included and rated at up to three years.
There is no wireless capability at all. Every code is typed at the lock, which removes the entire category of smart lock hacking risk from the decision.
Why it works on a garage side door
When replacing an existing lever, no drilling is needed, and the battery changes without taking the assembly off the door. That matters on a steel garage door where you do not want to disturb the panel.
Emergency egress and the reversible lever make it usable on either handing and safe to exit from inside.
Where it falls short
The fit requirement is the big one. It needs 5.5 inch centre-to-centre spacing between the knob and the deadbolt, and at 5.125 inch the interior cover cannot slide up far enough to reach the battery or the programming button.
Some owners report the handle screw loosening with temperature swings and the extended latch leaving the bolt only partly extended.
How to Choose a Keypad Lock for a Garage Side Door
Start with the door, not the brand. A keypad lock is a boring mechanical device that must fit the hole you already have and survive the weather it already lives in. Eight criteria decide whether you end up with a good install or a return.
1. ANSI/BHMA security grade
Grade 2 is the sensible floor for an exterior door; Grade 3 is residential-basic and Grade 1 is the commercial top tier. Most of the locks on this list carry Grade 2 or Grade 3 certification, and we would not put a lock on a walk-in garage door without a published grade at all.
2. Deadbolt, lever or knob
A deadbolt throws a hardened bolt into the strike plate and gives the largest security footprint. A lever puts the keypad where your hand already is and is easier with full hands or a keyring. A knob is simplest to install but offers the least security, so reserve it for sheds and outbuildings.
3. Weather resistance and cold-weather battery life
An unheated garage is a genuinely harsh environment: wide temperature swings, condensation, and driving rain on a door with no roof overhang. Look for a published IP54 or IP65 rating and a stated operating temperature range. Two of the locks here run to -35F, which is the number we would look for in a cold climate.
Cold weather does not just affect the lock, it affects the cells. Lithium cells hold their charge far better below freezing than alkaline ones, so if your garage is unheated, that is a cheaper upgrade than a more expensive lock.
4. Power and backup behaviour
Every lock here runs on batteries rather than house power, so a power outage is a non-issue. The question that matters is what happens when the cells die. Two options are a 9V emergency terminal or USB-C backup power, and every lock here ships with at least one physical key.
5. Entry methods
Code, key, fingerprint and one-time guest code are the four useful ones. Fingerprint locks suit a high-traffic door; code-plus-key suits most people; one-time codes are worth having if a contractor ever needs access.
6. Door compatibility
Measure before you buy. You need the bore diameter (most are 2-1/8 inch, and several locks here refuse a 38mm hole), the door thickness (up to 2 inch for most, 2-1/2 inch for the thick-door picks), the backset (2-3/8 or 2-3/4 inch), and the spacing between knob and deadbolt if a lever is involved.
7. Rekeying to match an existing key
If you want one key for every exterior door, Kwikset SmartKey is the clear answer on this list. Both Kwikset levers can be rekeyed to your existing house key in seconds without a locksmith. On other brands you are looking at swapping the cylinder, which is a different job.
8. Lockout after failed attempts
A keypad is only as strong as the number of guesses an attacker gets. Locks with a wrong-entry limit lock the keypad for several minutes after repeated failures, which turns a fast attack into a slow one. This is worth more than an extra two user codes.
Common mistakes to avoid
The most common error is buying a garage door opener keypad for a personnel door. It looks related in a search result and it cannot secure the door you are worried about. The second is under-measuring a thick door. The third is buying an unrated plastic-body lock for an exterior entry.
How to Install a Keypad Deadbolt on a Garage Side Door
Most of these installs need a screwdriver and about 20 minutes. Take the measurements first, because a lock that does not fit is the only real mistake that costs you an afternoon.
1. Measure before you order. Bore diameter, door thickness, backset, and the distance from the door edge to the centre of the existing bore.
2. Remove the old hardware. Take the existing deadbolt off and keep the screws and strike plate if the new lock uses the same pattern.
3. Check the door closes properly. Latch the door by hand several times. A warped steel door is why some deadbolts fail to throw fully.
4. Fit the strike plate. If the plate sits proud, chisel a shallow recess so the door closes without the bolt fighting the frame.
5. Insert the bolt and assemble. Keep both panels as square to the door as possible, and tighten the mounting bolts evenly rather than driving one side hard.
6. Fit the batteries before programming. Some locks, including the TEEHO, must be reset after the first power-up to detect door handing.
7. Programme your master code, then test from outside. Add user codes only after the master works, and confirm the inside thumbturn locks and unlocks smoothly.
Tools: a Phillips screwdriver, a tape measure, a chisel for the strike recess on a steel door, and a spare set of AA or 9V batteries. Nothing else is usually needed.
How We Picked These Locks
Every lock here was selected on published specifications and owner feedback rather than brand reputation alone. We started from the use case, which is a specific door: an exterior, often unheated, often hidden from view, already bored for a standard deadbolt.
We weighted four things. First, a stated ANSI/BHMA grade, because an unrated lock has no business on an exterior entry. Second, a published weather rating and temperature range, since this door sees more exposure than a front door. Third, mechanical key backup, because a dead battery must never lock out the family. Fourth, fit documentation, because most returns on garage door hardware come from a bore or thickness mismatch rather than a faulty lock.
Ratings and review counts come from the product listings, and the pros and cons reflect what buyers actually reported rather than what the marketing claims. Where reviews flagged installation problems, we said so plainly instead of burying it.
Frequently Asked Questions
What is the difference between a garage keypad and a door keypad lock?
A garage door opener keypad is a wall-mounted remote that sends a radio signal to raise or lower the overhead sectional door. It never secures a door. A door keypad lock is installed in the walk-in personnel door itself and throws a deadbolt, so it secures the side entrance whether or not the overhead door is open.
Do keypad locks work in cold weather?
They do, but battery life shortens as temperatures fall in an unheated garage. Look for a published operating range, and two of the locks here are rated down to -35F. Lithium cells hold their charge far better below freezing than alkaline ones. Expect to change batteries more often in a cold climate than the box claims.
What happens if the batteries die in a keypad lock?
Nothing catastrophic, provided you planned for it. Every lock on this list includes at least one physical key, and several add a 9V emergency terminal or USB-C backup power so you can wake the lock with a battery or a power bank. Low-battery indicators on all of them give you warning before this happens.
Can you rekey a keypad lock to match your existing house key?
Yes, and it is the most common request on garage door forums. Both Kwikset locks here use SmartKey, which rekeys the cylinder to an existing key in seconds without a locksmith. On other brands you would replace or rekey the cylinder yourself, which is a more involved job.
Will a keypad lock fit a thick garage side door?
Most fit doors from 1-3/8 inch up to 2 inch thick. Two locks here handle doors up to 2-1/2 inch, which covers the insulated entry doors people ask about. Also check the bore: most locks need a 2-1/8 inch hole and several will not accept a 38mm bore. Measure the door before ordering.
Is a garage side door a common entry point for burglars?
It is a documented secondary target, because it is often unmonitored, sits behind the house and is fitted with a lock nobody has thought about since installation. A keypad lock removes the hidden-key vulnerability, and adding a camera and exterior lighting covering that door closes off the low-effort approach entirely.
Final Verdict
The best keypad locks for garage side doors in 2026 come down to one question: how exposed is that door, and how many people need in. For a standard exterior man door with a normal bore, the Schlage BE365 is our pick, with Grade 2 certification, a limited lifetime mechanical warranty and a published temperature range that runs from -35C to 66C on the outside escutcheon.
Go with the TEEHO TE001 if owner satisfaction matters most to you, with the Kwikset 955PML if you want a lever and SmartKey rekeying to your house key, and the iulock IU-30 or BOTHSTAR YJ20 if the door is thick or the lock is going on a shed. Measure the bore and the door thickness before you order, and check that a spare key is in your pocket the day it goes on.
