Alarm.com Smart Locks Explained: Z-Wave & PowerG Locks, Yale, Kwikset, Schlage Integration
Smart locks are one of the most practical additions to an Alarm.com security system. When integrated with your panel and the Alarm.com app, they let you control access remotely, track who comes and goes, assign individual user codes per person, and tie door locking directly into your security automations—all without a separate smart home hub or subscription to a third-party platform.
Benefits of Smart Locks with Alarm.com
The most immediate benefit is remote access: you can lock or unlock any paired door from the Alarm.com app regardless of your location. This is useful for letting in a contractor, a family member who forgot their key, or confirming that a door is locked after you’ve already left. Every lock and unlock event is logged with a timestamp and the name of the access code used in the Alarm.com activity feed, giving you a clear, searchable record that a traditional deadbolt cannot provide.
Access logs become especially useful when combined with per-person user codes. Instead of sharing a single household PIN with everyone, you can assign a distinct code to each family member, employee, or service provider. If a code needs to be revoked—because a contractor’s job ended or a code was shared without permission—you can delete that one code without affecting any others. Temporary codes can be set to expire automatically on a specific date and time, eliminating the need to remember to revoke them manually.
Smart locks also integrate directly with your security system’s arm and disarm state. You can set rules so that all doors lock automatically when the system arms to Away mode, or receive push notifications any time a specific door is unlocked. On systems that support it, a verified alarm event can trigger a lock command to prevent re-entry while a response is in progress.
How Alarm.com Smart Locks Work
Alarm.com-compatible smart locks communicate with your security panel using one of three protocols: Z-Wave, PowerG, or Wi-Fi (cloud integration). Understanding the difference matters for choosing the right lock and avoiding installation problems down the line.
Z-Wave is the most widely supported protocol across Alarm.com-compatible locks. Z-Wave locks pair directly with the panel’s built-in Z-Wave controller and communicate over a mesh network operating at 908.42 MHz in North America. Because battery-powered devices like locks do not act as Z-Wave mesh repeaters, the mesh extends only through AC-powered Z-Wave devices such as smart outlets or in-wall switches. Standard Z-Wave has an open-air range of roughly 30–50 feet between devices, and signal must pass through walls and obstructions. Z-Wave Long Range (Z-Wave LR), supported by newer panels such as the Qolsys IQ Panel 4, is a separate protocol variant that allows compatible devices to communicate directly with the panel at significantly greater distances without relying on the mesh network at all—making range issues largely a non-issue for most home installations.
PowerG is a proprietary Qolsys protocol operating at 915 MHz with frequency-hopping spread spectrum (FHSS), which improves reliability in environments with wireless congestion and provides encrypted communication by default. The IQ Lock-PGK is the only PowerG smart lock currently listed as Alarm.com-compatible, and it works exclusively with Qolsys IQ panels. PowerG has a rated open-air range of up to 2 km—far exceeding standard Z-Wave—making it the strongest option for installations where Z-Wave coverage is difficult to achieve or where large properties are involved.
Wi-Fi locks such as the Schlage Encode connect to your home’s Wi-Fi network and integrate with Alarm.com through a cloud-to-cloud connection rather than communicating directly with the panel. This means range is not a factor, but the lock’s remote functionality depends entirely on your internet connection remaining active. A router reboot, ISP outage, or Wi-Fi password change will disrupt remote access until the lock reconnects. Local keypad access using stored codes continues to work regardless of internet status.
Top Compatible Models
The models below are listed on Alarm.com’s official hardware compatibility page (as of 3/9/26) and represent the most commonly installed options across the three supported protocols.

Yale is widely considered the premium residential choice for Alarm.com installations—the Assure series balances aesthetics, multiple entry-style options, and consistent Z-Wave reliability. Schlage deadbolts are favored for durability and their ANSI Grade 1 physical security rating. Kwikset locks work reliably with Alarm.com, but the SmartKey re-key cylinder found on many Kwikset models has a documented vulnerability that allows bypass without a key using widely available tools; this is worth factoring in if physical attack resistance is a priority. The IQ Lock-PGK is the clear choice for Qolsys panel users who want maximum communication range or who just don’t want to deal with communication problems.
Installation and Pairing Guide
The pairing process depends on which protocol your lock uses. For Z-Wave locks, the lock must be in close range of the panel—ideally within 6 feet—during the initial pairing process. On a Qolsys IQ panel, navigate to Settings > Advanced Settings > Installation > Devices > Z-Wave Devices and select Add Device. Put the lock into inclusion mode using the manufacturer’s procedure (typically a specific button press sequence on the interior assembly), and the panel will discover and register it. Once pairing is confirmed, run a Z-Wave network rediscovery before installing the lock in its final location. This ensures the panel accurately maps signal paths through the mesh. For Z-Wave Long Range (LR) locks, use the SmartStart QR code method of enrollment to enable long range.
After the lock appears in the panel’s device list, Alarm.com will sync it to your account within a few minutes. Confirm it’s visible by opening the Alarm.com app and navigating to the Locks section. If it doesn’t appear within 10 minutes, trigger a manual panel sync from the Surety System Manager. All subsequent code management should be done through the Alarm.com app rather than directly on the lock’s keypad.
For the IQ Lock-PGK (PowerG), pairing follows the PowerG enrollment process rather than Z-Wave. On the IQ panel, go to Settings > Advanced Settings > Installation > Devices > Security Sensors and enroll the lock as a PowerG device. Given PowerG’s extended range, proximity to the panel during pairing is much less of a concern than with Z-Wave.
For Wi-Fi locks like the Schlage Encode, there is no panel pairing step. The lock connects to your home’s Wi-Fi network via the manufacturer’s app, and you then authorize the Alarm.com integration from within the Alarm.com app under Connected Services. Once authorized, the lock appears in the Alarm.com locks interface and supports all standard code management and automation features.
Regardless of protocol, it is important to manage all user codes exclusively through the Alarm.com platform after initial setup. Codes added directly on the lock’s keypad or through the manufacturer’s own app can create conflicts with Alarm.com’s code database and result in sync failures or codes that stop working unexpectedly.
Managing User Codes and Schedules
User codes are managed in the Alarm.com app under Users. The same code used to disarm the alarm is used to unlock the door. You can create a code for each person and give it a descriptive name—when that code is used, the name appears in the activity log so you know exactly who unlocked the door. Codes can be configured as permanent, temporary (active between a specific start and end date and time), or recurring (active only during defined hours on selected days of the week).
Recurring codes are useful for regular service personnel who should only have access during defined windows—for example, a housekeeper who visits every Tuesday from 9 AM to 1 PM, or a dog walker with a standing afternoon slot. The schedule enforces itself automatically without any action on your part once it’s configured.
Temporary codes are useful for one-time or short-term access. A code issued to a contractor can be set to expire the moment their job ends, with no follow-up required. The activity log will still record any access attempts using that code after expiration, providing a complete audit trail. The number of codes a lock can store varies by model—most residential Z-Wave locks support between 30 and 100 slots—but Alarm.com manages slot allocation automatically.
Automation Rules Examples
Alarm.com’s rules engine lets you connect lock behavior to other system and app events. The following configurations are commonly used in practice.
Auto-lock on Away arm: When the system arms to Away mode—from the panel, app, or key fob—all paired locks automatically lock. This prevents the common scenario of leaving a door unlocked when leaving the house.
Unlock notification by code: Receive a push notification any time a specific door is unlocked, or specifically when unlocked using a particular user code. This is useful for knowing when children arrive home from school, when a delivery has been dropped inside, or when a service visit has taken place.
Geofence-triggered lock: The Alarm.com app’s geofencing feature can automatically remind you to lock all doors when your phone’s GPS indicates you’ve left a defined boundary around your home—providing a reliable fallback if you forget to arm or lock manually.
Disarm-to-unlock: Unlocking the froon door can simultaneously disarm the alarm, eliminating the need to enter a second code on the alarm itself when you arrive home.
Auto-relock timer: Most locks support auto-relock, which re-engages the deadbolt a configurable number of seconds after it was unlocked. This can be set on the lock’s hardware or managed through Alarm.com rules depending on the model.
Troubleshooting Common Problems
Lock shows “Malfunction” in the app: A malfunction status often indicates a communication issue between the lock and the panel. Start with the battery—low batteries are the most common cause of erratic Z-Wave behavior. Replace with fresh name-brand alkaline batteries (Energizer or Duracell are recommended), then allow a few minutes for the status to update. If malfunction persists with fresh batteries, perform a Z-Wave network rediscovery from the panel.
Low battery alert won’t clear after battery replacement: The low battery status in Alarm.com can take several hours to update passively after a battery swap. To clear it immediately, run a Z-Wave network rediscovery or trigger a manual panel sync from the Alarm.com app. If the alert returns quickly after fresh batteries are installed, inspect the battery compartment for corrosion or a loose contact, and try a different battery brand.
Range and connectivity issues (Z-Wave, non-LR locks): Standard Z-Wave locks are battery-powered and do not repeat Z-Wave signals, so if the lock is far from the panel and there are no AC-powered Z-Wave devices in between, communication can be intermittent. The fix is to add a Z-Wave repeater or an AC-powered Z-Wave device—such as a smart plug or in-wall switch—between the panel and the lock. After adding the repeater, run a Z-Wave network rediscovery so the panel updates its mesh map. Locks communicating via Z-Wave LR or PowerG do not have this limitation.
User codes not syncing to the lock: Confirm the lock shows no malfunction status, then delete and re-add the code in the Alarm.com app. Avoid entering codes directly at the lock keypad, as this is a common source of sync conflicts. For persistent code sync issues, the Surety support forum thread on Z-Wave smart locks documents known edge cases and solutions from real installations.
Lock won’t pair or drops from the network: If a previous pairing attempt was incomplete, the lock may hold a stale network association. Perform a factory reset on the lock and run an “Exclude” operation on the panel (found in the Z-Wave Devices menu) before attempting a fresh inclusion. Always keep the lock within 6 feet of the panel during the pairing process.
Frequently Asked Questions
How long do batteries last in a smart lock? Most Z-Wave deadbolts last 6–12 months on a set of AA alkaline batteries under typical use of 10–15 locking operations per day. Heavy traffic, cold weather, and frequent Z-Wave polling can reduce battery life. The Alarm.com app sends a low battery notification before power is critically low, giving you time to replace batteries before the lock loses functionality.
Do I need a Z-Wave repeater? Not necessarily. If the lock is within reliable Z-Wave range of the panel—generally within 30–50 feet through typical interior walls—no repeater is required. If your installation involves greater distances, thick walls, or significant RF interference, adding a Z-Wave repeater or an AC-powered Z-Wave device between the panel and the lock will resolve most range problems. Locks using Z-Wave LR on a compatible panel like the Qolsys IQ Panel 4, or PowerG locks, do not require repeaters in any typical installation.
Is Kwikset safe to use with Alarm.com? Kwikset locks integrate reliably with Alarm.com and work well for access management. However, the SmartKey re-key cylinder included on most Kwikset residential models has documented physical vulnerabilities that allow the lock to be bypassed without a key using a common tool. For installations where the lock is the primary physical barrier and resistance to physical attack matters, Yale or Schlage models are generally considered stronger choices.
Does the IQ Lock-PGK work with any Alarm.com panel? No. The IQ Lock-PGK uses the PowerG protocol and is only compatible with Qolsys IQ panels (IQ Panel 2 Plus, IQ4, and related models). It will not function with DSC, Honeywell, or other non-Qolsys panels even if those panels otherwise support Alarm.com.
Can I use a smart lock without a Qolsys panel? Yes. Z-Wave locks work with any Alarm.com-compatible panel that includes a built-in Z-Wave controller, including 2GIG and Honeywell panels. Wi-Fi locks like the Schlage Encode also work with any Alarm.com account regardless of panel brand, since they connect through the cloud rather than the panel directly. Only PowerG locks require a Qolsys panel specifically.
What happens to the lock if my internet connection goes down? Z-Wave and PowerG locks communicate directly with the panel rather than over the internet, so local functions—keypad code entry, auto-relock, and rules triggered by panel arming—continue to work during an outage. Remote access via the Alarm.com app requires an active internet connection but Alarm.com panels utilize dual-path internet + cellular for maximum uptime. Wi-Fi locks lose remote access during an outage but retain local keypad functionality using stored codes.
If you’re ready to add a smart lock to your system, the IQ Lock-PGK is available at SuretyHome.com for Qolsys panel users. For Z-Wave lock questions, model-specific compatibility notes, and real-world pairing tips from other Alarm.com subscribers, visit the Surety community forum.
