How to Factory Reset an Amcrest Smart Lock

After restoring the device to factory settings the admin code will be 123456 and the user code will be 1234. All other user codes that have been set will be cleared and all other settings will be restored to its
original default settings.
Step 1: Remove one battery, wait 10 seconds, and put the battery back into the lock. You will hear a long beep and one short beep.
Step 2: Within 3 seconds, tap three times. The buzzer will beep and the indicator light will flash green indicating the device has been properly reset to its original factory settings.
