Based on 10 operations per day, a single, new set of Alkaline batteries will operate the lock for over a year.
For best results, use new non-rechargeable Alkaline batteries only.
When the system is idling, it consumes minimum power (very close to battery self-discharge rate). With a new set of alkaline batteries, the lock should be operable after years of idle.
Check your door alignment. If the deadbolt makes several unsuccessful attempts to lock or unlock the door, it may mean that the door is warped and the latch does not line up correctly with the strike. Operating the lock excessively reduces battery life. Avoid turning on the touchscreen unnecessarily.
Disable the Status LED, Auto-Lock, SecureScreen™, and mute the sound of the lock inside the Premis App.
