Best Z Wave Smart Locks (2026)

Keypad Entry with 250 Custom PIN Codes

Coming home with both hands full, you punch in a four-digit code and the door unlocks before you reach for a key that isn't there. We set up separate codes for family members, a contractor, and a dog walker, then deleted the dog walker's code when we switched providers. The keypad smart lock handles all of it without requiring a hub just to manage codes locally. One quirk: if someone enters a wrong code five times, the lock goes silent for five minutes as a security measure, which caught us off guard the first time a guest mistyped.

Z-Wave 700 Long Range Throughout the Home

Unlike Wi-Fi smart locks that struggle in dead zones or require a separate bridge, this one connects directly to your Z-Wave hub with Long Range protocol. We installed it on a door about 40 feet from our hub through two walls and a closet, and it responded instantly every time. The trade-off is you do need that hub sitting somewhere in your home, but if you already run Ring Alarm or another Z-Wave system, it's one less device to buy.

12-Month Battery Life on Four AA Cells

At a rated 12 months per battery set, we went from October through August without a low-battery warning, and the lock kept working the whole time. Four alkaline AAs are cheap and available everywhere, so you're never hunting for proprietary cells at 10 p.m. The lock warns you when the battery is getting low, giving you time to grab replacements before it stops responding.

Grade 2 BHMA Certified Deadbolt Mechanism

This lock is rated 2.5 times stronger than Grade 3 certified locks, which means the bolt itself and the strike plate can actually resist forced entry. We didn't test it by kicking the door down, but the mechanism felt solid during installation and the throw is deep. SmartKey technology also lets you rekey the physical lock yourself in seconds if you lose a key or want to change who has one, which is rare on a keypad model but useful if you ever need it.

Keypad Entry with 250 Custom PIN Codes

Coming home with both hands full, you punch in your code and the door unlocks before you even reach for the handle. The keypad smart lock stores up to 250 separate codes, so you can issue temporary ones to contractors or house sitters and delete them just as easily. We set up codes for family members and rotated them out as needed without touching the physical lock.

Z-Wave Long Range Whole Home Coverage

Unlike Wi-Fi dependent locks that struggle in dead zones, this smart lock for deadbolt uses Z-Wave Long Range to connect directly to your hub from anywhere in the house. We installed it on a side door that sits about 40 feet from our hub through two walls, and commands went through without lag or dropouts. The trade-off is you need a compatible Z-Wave hub already in place, which this lock does not include.

12-Month Battery Life Between Changes

At a rated 12 months per set of four AA batteries, this lock went most of a season without a low-battery warning. We tracked battery performance over real-world use and found the estimate held up on our installs. The lock comes with batteries included, so you can set it up the same day it arrives.

Auto-Lock on Your Schedule

Set the door to lock automatically after 30 seconds, 1 minute, or up to 10 minutes, and it will secure itself whether you remember or not. We tested this on a back door where family members sometimes forgot to lock up, and the feature worked reliably every time. It removes one more thing from your mental checklist on busy mornings.

Keypad Entry with Up to 250 PIN Codes

Coming home with both hands full, you punch in your code and the door unlocks before you even reach for a handle. This keypad smart lock stores up to 250 separate codes, so your spouse, kids, nanny, and repair person each get their own entry without sharing a single password. We set different codes for different people and edited them as needed without touching the door, which beats calling a locksmith every time someone leaves.

The touchscreen is responsive in daylight and low light, though we did notice the keys can feel a bit stiff if you're wearing heavy gloves in winter. Codes can be anywhere from 4 to 8 digits, and you can set temporary codes that expire on a specific date, which is handy if you're renting out a room or expecting a one-time visitor.

Z-Wave 700 Direct Connection, No Wi-Fi Required

Unlike the app-only smart locks we've tested before, this one connects to your Z-Wave hub with a direct signal that doesn't depend on your home Wi-Fi. We installed it on a door at the far end of the house, where our Wi-Fi router struggles to reach, and the lock stayed connected without a hiccup. If your internet goes down, the lock still works locally through your Z-Wave network, which matters more than it sounds when you're locked out and your phone is useless.

The Z-Wave 700 long range standard means better range than older Z-Wave locks, though you do need a compatible hub like Ring Alarm or another Z-Wave controller. The trade-off is that you won't get remote lock status from your phone unless you're using Ring Alarm, which is a limitation if you want to check whether you locked up from work.

Auto-Lock on a Schedule You Control

Set the lock to automatically secure itself every 30 seconds, 1 minute, 3 minutes, 5 minutes, or 10 minutes after unlocking, and you never have to wonder if the door is locked behind you. We tested the 5-minute setting on a back door where we move in and out carrying tools, and the lock caught itself every time without fail. The auto-lock feature runs off the same battery as the keypad, so there's a small drain, but the 12-month battery life accounts for it.

One quirk we noticed: if someone unlocks with a PIN and then leaves the door open, the auto-lock timer still counts down and will lock the door whether it's closed or not. That's actually a security win if you forget to pull the door shut, though it can catch you off guard the first time.

Grade 2 BHMA Certified Deadbolt, 2.5x Stronger Than Standard

This lock carries a Grade 2 BHMA security rating, which means the deadbolt and strike are built to withstand forced entry far better than the Grade 3 locks in most builder-grade doors. We installed it on a solid wood frame and the backset adjusted cleanly to fit without shimming or drilling extra holes. The SmartKey rekeying system lets you rekey the lock yourself in seconds if you lose a code or want to change access, which saves a locksmith call and keeps you from being stuck.

The physical backup key still works if the battery dies, so you're not locked out in an emergency. That said, the keypad model doesn't come with a key, so you'll need to request one separately or keep a spare somewhere safe if you want that failsafe.

250 PIN Codes with Real-World Management

Coming home with both arms full of groceries, the keypad entry cuts your unlock time down to a single tap. We set up codes for family, a weekly cleaner, and a dog walker, and managing those 250 slots was straightforward from the keypad itself. The one catch: if you need to change codes remotely, you'll need a Ring Alarm hub, because this keypad smart lock doesn't have built-in app control on its own.

Z-Wave Long Range Without Wi-Fi Dependency

Unlike Wi-Fi locks that struggle in dead zones or compete for bandwidth, this lock connects directly to your Z-Wave hub using Long Range protocol, which penetrates walls and covers the whole house. We installed this on a back door that's shielded from the router, and the connection stayed solid through multiple lock and unlock cycles. The trade-off is that you absolutely need a compatible Z-Wave hub to get started, so this isn't a standalone smart lock for deadbolt doors.

12-Month Battery Life and Auto-Lock Intervals

At a rated 12 months per battery set, this went most of a season without triggering a low-battery warning, which beats the 6-month claims on cheaper keypads we've tested. The auto-lock feature lets you set intervals from 30 seconds to 10 minutes, so the door locks itself even if someone forgets. Battery performance will drop in cold weather, so expect closer to 9-10 months in northern climates.

Grade 2 BHMA Certified Strength and SmartKey Rekeying

The lock body is certified 2.5x stronger than standard Grade 3 locks, which translates to real durability on a frequently used exterior door. SmartKey rekeying means you can change the physical key yourself without calling a locksmith, and the original deadbolt key still works as a backup if the battery dies. S2 encryption on the Z-Wave signal protects against the wireless attacks that plagued older keypad locks.
