Best Smart Locks for Security Systems: Ring Alarm, SimpliSafe and Abode

How lock and alarm integration works

A smart lock bought on its own gives you keyless entry and remote locking. Integrated with your alarm, it ties locking and arming together. The three systems covered here wire the link differently, and the direction matters:

• Ring Alarm arms from the lock. Lock with an access code created in the Ring app (or with one-touch locking, where the lock has it) and Ring Alarm arms Away mode; unlock with an access code and it disarms. A code created on the lock itself does not work for this, and a compatible Ring subscription is required.
• SimpliSafe locks from the alarm. Arming the system in Home or Away locks every equipped door, and SimpliSafe says that whenever you unlock the Smart Lock, including with a valid PIN on its PIN Pad, it also disarms the system. SimpliSafe states the Smart Lock cannot arm the system when you lock the door, so lock-and-leave still needs the keypad, app or key fob.
• Abode uses automations. Abode's product page publishes Auto Lock and Unlock automations through its CUE automation engine, which you configure, rather than a fixed arm-triggered behaviour.

Ring documents lock-to-arm for Away mode, so plan on arming Home mode yourself at night. When a smart lock battery dies it stops responding, none of the major makers says it unlocks itself, and you get in by key, emergency power or a power bank; what happens when a smart lock battery dies covers each brand.

Which locks each system supports

As of October 2026, by each vendor's own pages:

Match the full model number, not just the brand. The same lock family is often sold in Wi-Fi, Bluetooth and Z-Wave versions that look identical, and only the version your system lists will link to the alarm. If you already own a Z-Wave lock on Ring's list, Ring says pairing it costs nothing extra.

Ring Alarm: the certified Z-Wave list and what it needs

Ring Alarm talks to locks over Z-Wave, the same radio its own sensors use, and Ring says Works with Ring certified locks require an Alarm Base Station because Z-Wave devices need a Z-Wave controller. Ring's integration overview says Ring Alarm supports more than 35 Z-Wave locks from these three makers; its published compatibility list, as of October 2026, shows 34 distinct model numbers once two repeated Schlage rows are removed:

Ring flags the last four Yale models (YRD410, 450, 420 and 430 ZW2) as not compatible with "Touch" models. Once paired, Ring lists lock and unlock from the app, with a key or with shared PIN codes; Alexa control; and notifications when the disarm code opens the lock, when someone tampers with it, and when it malfunctions, jams or goes offline, plus a device history showing which code and lock were used. On security, Ring says its Alarm sensors use Z-Wave S2 (Elliptic Curve Diffie-Hellman key exchange and AES encryption) and that you need to check with the lock maker whether a given lock uses S2. For how Z-Wave compares with Zigbee, see Z-Wave vs Zigbee for security sensors.

The subscription line is the one to read carefully. Ring says lock arming works when you hold a compatible Ring subscription, and that one is required for digital arming and disarming and certain other in-app features. Ring's plans page, as of October 2026, lists Ring Solo at $4.99/month, Ring Multi at $9.99/month and Ring Pro at $19.99/month or $199.99/year, with 24/7 professional monitoring in Ring Pro. Ring's lock articles do not name which plans count as compatible, so confirm in the app before relying on it; Ring monitoring cost covers what each plan includes. One inconsistency to know about: Ring's integration overview says lock integrations are available only in the United States, while its newer arming article says the United States and Canada.

Ring's store also sells locks labelled Works with Ring that never touch the alarm. The Schlage Encode ($299.99) is a Wi-Fi deadbolt that Ring lists as BHMA/ANSI Grade 1 on 4 AA batteries, with locking and unlocking from a doorbell or camera's Live View. The Level Bolt ($199.99) needs a Video Doorbell Pro to link through Amazon Sidewalk. If you want the lock to arm and disarm the alarm, buy a Z-Wave model from the certified list; if you only want to let people in from the doorbell feed, a Wi-Fi lock works without the Base Station.

SimpliSafe: its own Smart Lock or August

SimpliSafe publishes two lock routes and no list of third-party Z-Wave locks, the main difference from Ring.

The SimpliSafe Smart Lock (Series 2) is a retrofit that mounts over the inside of a standard single-cylinder deadbolt, keeps your existing key working, and runs on 4 AA batteries. It requires a SimpliSafe Gen 3 system; SimpliSafe recommends keeping the system on Wi-Fi but says Wi-Fi is not required. Beyond the arm-locks, unlock-disarms behaviour above, SimpliSafe's product and support pages list:

• Auto-Lock after 30 seconds, 1 minute or 5 minutes.
• Door sensor sync. With an Entry Sensor on the same door, the lock will not throw the bolt while the door is open.
• Wrong-PIN handling. From the fifth wrong PIN the lock sends app alerts, applies progressively longer lockouts, and cameras on the system start recording. After the eleventh wrong attempt, customers with professional monitoring get a call from the monitoring center.
• Duress PIN. It unlocks and disarms as normal but silently alerts the monitoring center that you need police, with select monitoring plans.

August locks. SimpliSafe supports the August Wi-Fi Smart Lock and the August Smart Lock + Connect. August's own SimpliSafe page also lists a Wi-Fi Smart Lock + Keypad bundle; the Yale Approach Lock, which August also sells, is not on either company's SimpliSafe list, so do not assume it works. Setup happens in the SimpliSafe web account, not the app: SimpliSafe says it is not currently possible from the SimpliSafe App. You open Integrations, authorize August, enter a PIN August emails you, and pick how the lock reacts to each arming state.

Which plan you need. SimpliSafe's August article requires a supported residential or business monitoring subscription, and August's page says syncing is for SimpliSafe customers on interactive professional monitoring. SimpliSafe's plans page lists August compatibility in its comparison of the Core, Pro and Pro Plus plans; Core is $32.99 a month as of October 2026 on SimpliSafe's support page ($1.10 a day on its plans page). We could not find a SimpliSafe page that says whether the Standard plan supports August, so confirm with SimpliSafe before buying an August lock for Standard. With no plan at all, SimpliSafe says you keep live camera view and remote arm and disarm in the app, but lose emergency dispatch and the built-in network backup. The full plan breakdown is in is SimpliSafe worth it.

Which to buy, on paper: for an existing SimpliSafe system, the SimpliSafe Smart Lock is $80 cheaper than either August option (our arithmetic) and does not depend on a cloud link between two companies. August makes sense if you already own one, or want a lock that also works with Apple HomeKit, which August lists for its Wi-Fi Smart Lock.

The integrated locks by published specs

The SimpliSafe and Abode locks are retrofits: they replace the interior thumb-turn side of your existing deadbolt, so your exterior hardware and keys stay the same. That is faster to install, renter-friendlier, and keeps your existing key as backup. The Works with Ring route mostly means replacing the full deadbolt, and because it is a certification program rather than one product, you pick a lock grade and finish and check it against Ring's list before buying.

Of the options covered here, the SimpliSafe Smart Lock is the cheapest published integrated lock at $119.99, the Abode Lock adds fingerprint access, and the Ring-certified route offers the widest hardware choice at generally higher prices. If you rent, a retrofit model keeps the outside of the door and the landlord's key unchanged; see smart locks for renters. Doorbell cameras follow the same first-party and partner pattern; see video doorbells that work with alarm systems.

What to check before buying any of these

Deadbolt compatibility first: retrofit locks require a standard single-cylinder deadbolt that turns smoothly. A misaligned strike plate that makes your thumb turn stiff will defeat a motorized lock; fix the alignment before installing, since the motor will not force what your hand has to.

Second, match the lock to the system you actually run, not the other way around. The SimpliSafe Smart Lock requires a SimpliSafe Gen 3 system, Ring's alarm integration requires the Base Station and a lock on Ring's certified list, and the Abode Lock works on its own but its Auto Lock and Unlock automations run through Abode's CUE engine. If you are still choosing the system itself, settle that first and treat the lock as an accessory decision; best DIY security systems is the place to start.

Third, think through the failure modes honestly. Battery-powered locks warn before dying, but plan for the dead-battery case: retrofit models keep your physical key working, which is a real advantage over key-free keypads. And a smart lock does not strengthen the door; a weak strike plate or door frame yields to force regardless of what is driving the bolt. For the physical-hardening half of door security, see the apartment door security checklist, which applies to houses too.

A smart lock's physical strength comes from its bolt and BHMA grade, while its added risks are digital and battery related; are smart locks safe walks through both. A keypad deadbolt needs no app or Wi-Fi, while a Wi-Fi smart lock adds remote control, logs and alarm integration; keypad deadbolt vs smart lock compares them.
