The Best Combination Door Locks of 2026
"Combination door lock" actually covers three different mechanisms. The Schlage BE365 Camelot ($100-130) is the classic battery-powered keypad deadbolt, with a mechanical key as backup if the battery dies. The Lockey M210 EZ (around $150-230) is 100% mechanical - no batteries, no wiring, nothing to charge or fail, but everyone shares one code and there's no key cylinder at all. The Yale Assure Lock 2 ($160-260) is the smart-keypad step up - codes plus app control and auto-lock. All three fit a standard deadbolt bore with no drilling. Prices verified August 2026.

There are three kinds of "combination lock" - and most buying guides don't say so
Search for a combination door lock and most results are just retailer listings, mixed together with no distinction between three genuinely different mechanisms. A battery keypad deadbolt, like the Schlage BE365, uses electronics to store multiple codes and runs on a 9-volt battery - convenient, but it needs power. A fully mechanical push-button lock, like the Lockey M210 EZ, has no battery, no wiring, and no electronics at all; the numbers are moved by the buttons themselves, the same idea used on office-door cipher locks for decades. A smart keypad lock, like the Yale Assure Lock 2, adds an app, remote access, and auto-lock on top of a keypad. They solve different problems, so the right pick depends on what you're actually trying to avoid: dead batteries, forgotten codes, or just wanting the most features.
How to choose
- Power source: a mechanical lock like the Lockey M210 EZ never needs a battery - there's nothing to die or replace, ever. A battery keypad like the Schlage BE365 runs on a 9-volt battery - Schlage rates it for up to 2 years of typical use - with a low-battery warning before it goes dead. A smart keypad like the Yale Assure Lock 2 also runs on batteries, plus Wi-Fi on some configurations.
- Keyed vs keyless: the Schlage BE365 and most Yale Assure Lock 2 configurations keep a physical key as backup, so a dead battery or forgotten code still has a fallback. The standard Lockey M210 has no key cylinder at all - it's fully keyless - so if everyone forgets the combination, only reprogramming or a locksmith gets you back in.
- One shared code vs per-person codes: a mechanical lock like the M210 has one programmable combination that everyone who knows it shares (you can re-code it, but not give each person their own). An electronic keypad like the BE365 stores up to 19 separate four-digit codes, so you can hand out and delete individual codes without changing the code everyone else uses. The Yale Assure Lock 2 works the same way through its keypad and app.
- App and remote access: only the smart pick, the Yale Assure Lock 2, checks this box - it adds remote lock/unlock and auto-lock on top of the keypad. Neither the Schlage BE365 nor the Lockey M210 connects to anything.
Need a combination lock for a business or office door?
None of the three picks above are rated for heavy commercial traffic. The lock that's been on office and utility doors for decades is the dormakaba Simplex 1000 - a fully mechanical push-button cylindrical lock with no batteries or wiring, combination entry from outside, and free egress from inside at all times. Dormakaba doesn't list a price online; Simplex locks are sold through commercial locksmith distributors and quoted per door. If you're securing a business entrance, the honest answer is to call a commercial locksmith and ask about the Simplex line rather than trying to make a residential keypad deadbolt do that job.
The picks
1. Schlage BE365 Camelot Keypad Deadbolt
The classic battery keypad deadbolt - the one most people picture when they say "combination lock." It runs on a single 9-volt battery - up to 2 years of typical use, per Schlage - with a low-battery warning before it dies, and stores up to 19 four-digit user codes so you can hand out and delete codes individually. A mechanical key override is included, so a dead battery or a keypad fault never locks you out entirely. It's sold in Camelot and Plymouth trim styles across several finishes, and it's in stock at Amazon, Lowe's, Home Depot, GoKeyless, doorhardwarecenter, and securitybase.
Pros
- Mechanical key override backs up the keypad and the battery
- Stores up to 19 separate user codes - not one shared code
- 9-volt battery lasts up to 2 years of typical use, with a low-battery warning
- Widely stocked; Camelot and Plymouth trims in several finishes
Cons
- Still battery-powered - needs a fresh 9-volt eventually
- No app or remote access - it's a standalone keypad
- A key exists, which some buyers specifically want to avoid
2. Lockey M210 EZ Mechanical Keyless Deadbolt
A 100% mechanical push-button deadbolt - no batteries, no wiring, no electronics of any kind, so there's nothing to charge, replace, or fail electronically. One programmable combination controls the lock, and it's re-codeable, but everyone who uses the door shares that single code rather than getting their own. The standard M210 has no key cylinder at all - it's genuinely keyless, not just keyless-first-with-a-backup-key. The double-combination M210DC variant adds a second combination on the inside, but still no key. The current "EZ" version installs without extra drilling on a door that already has a standard 2-1/8" deadbolt bore. Lockey enforces minimum advertised pricing, so expect to pay close to list wherever you buy it.
Pros
- Genuinely no batteries or wiring - nothing to die, ever
- Fully keyless - no key cylinder to pick, bump, or lose a key to
- EZ install plate avoids extra drilling on most existing bores
- Lifetime mechanical warranty from Lockey
Cons
- One shared code for everyone, not per-person codes
- No key backup at all - a forgotten code with the standard M210 means reprogramming or a locksmith
- Costs more than the battery-powered Schlage BE365
- Lockey enforces minimum advertised pricing, so the price rarely drops much below list anywhere
3. Yale Assure Lock 2
For buyers who want more than a plain combination lock - codes plus app control, remote lock/unlock, and auto-lock behind you. It's sold in several configurations (Bluetooth or built-in Wi-Fi, touchscreen or push-button), and keyed on most of them, though the fingerprint version is fully keyless. It's the pick if the keypad itself isn't the point - the app and automation are.
Pros
- Adds app control and auto-lock that neither the BE365 nor the M210 offers
- Multiple configurations - pick Wi-Fi, touchscreen, or fingerprint
- Keyed backup on most configurations
- Widely stocked, well-supported smart lock line
Cons
- Costs more than a plain battery keypad deadbolt
- Wi-Fi and remote features need the right configuration and setup
- Still battery-powered, like the BE365 - not a "never charge it" option
Our pick: Schlage BE365 Camelot Keypad Deadbolt
For most doors, the Schlage BE365 is the right combination lock - it's the proven battery keypad design, it keeps a mechanical key as backup, and it's the cheapest of the three picks here. If you specifically don't want a battery in the equation - ever - the Lockey M210 EZ is fully mechanical, though you give up per-person codes and any key backup. If you want app control and auto-lock on top of the keypad, step up to the Yale Assure Lock 2. For a business or office door, skip all three and ask a commercial locksmith about the dormakaba Simplex 1000 instead.

Frequently asked questions
- What happens if the battery dies on a keypad combination lock?
- On the Schlage BE365, a low-battery warning sounds before the 9-volt battery actually dies, and even after it's fully dead, the mechanical key override still opens the door - you're never locked out by a dead battery alone. Most Yale Assure Lock 2 configurations work the same way with a backup key, though the fingerprint-only version is fully keyless and has no key fallback. If you never want to think about a battery, the fully mechanical Lockey M210 EZ has no battery to die in the first place.
- Can you open a fully mechanical combination lock without the code?
- Not through the keypad itself - the standard Lockey M210 has no key cylinder to fall back on, so if everyone forgets the combination, you're relying on reprogramming the lock or calling a locksmith to bypass it, the same as any other lock without a working key or code. That's the trade-off for having no batteries: there's also no electronic or key-based backdoor.
- Are keypad door locks safe - can the code be guessed or the lock be bumped or picked?
- Schlage rates the BE365 Grade 2/AAA - ANSI Grade 2 plus the top AAA residential BHMA grade for security, durability, and finish - and pitches it for residential and light-commercial doors. Lockey markets the M210 as bump-proof and pick-proof by design, since it has no pin-tumbler cylinder for a standard bump key or pick to work on in the first place. As with any keypad, the practical risk is a shared or simple code (like 1-2-3-4) being guessed - use a non-obvious combination and change it if you suspect it's been seen.
- What's the difference between one shared code and per-person codes?
- A mechanical lock like the Lockey M210 has a single combination that everyone who knows it shares - you can re-code it, but not give each person their own. An electronic keypad like the Schlage BE365 stores up to 19 separate four-digit codes, so you can assign and delete individual codes without changing the code everyone else uses. The Yale Assure Lock 2 works the same way through its keypad and app.
- Is there a combination lock rated for a business or office door?
- Yes - the dormakaba Simplex 1000 is the mechanical push-button lock that's been standard on office and utility doors for decades: combination entry from outside, free egress from inside at all times, and no batteries or wiring. It's sold through commercial locksmith distributors and quoted per door rather than listed at a fixed retail price, so the honest move is to call a commercial locksmith for a quote rather than trying to stretch a residential keypad deadbolt into that role.
