Z-Wave locks use encrypted communication over Z-Wave, meaning their communication is completely secure. With this added security, the lock and the controller must use additional Z-Wave commands to learn-in and communicate. With each additional command sent, the probability of a communication breakdown increases.

Important: Do not add or delete user codes locally to or from the lock. Only use the Alarm.com web interface for user code management. 

To lower the chances of a learn-in failure for locks, complete the following during installation. 

1. Begin with the lock within 6 feet of the panel or module.
2. Delete the lock from the Z-Wave network.
3. Place the panel into Add Mode and trigger the lock.
4. Wait two minutes before locally operating the device.
5. Verify that the lock shows up on the Alarm.com website and responds to lock/unlock commands.
6. Move the lock to its final location and run a Network Rediscovery.

If the lock is not completing secure enrollment, see Z-Wave device is not completing secure enrollment.
