How Long Will The Battery Last for my Premis Lock?
4xAA batteries are expected to last up to a year based on 10 entries per day. However, misaligned doors where the lock faces resistance during lock/unlocking will shorten the battery life since the motor uses more power to exercise the latch. In addition, properly “handing” or calibrating the lock as outlined in the installation guide will maximize the battery life. Refer to the step 5 in the installation instructions.
