How do I install/replace my 905 Keyless Deadbolt batteries?
If the 4 AA batteries are too low to operate the lock, use a 9-Volt Alkaline battery to temporarily power the lock.
Make sure both terminals on the 9-Volt battery touch the terminals below the keypad. When lock has enough power you will hear 3 short beeps. Hold the 9-Volt in place while entering your user code to unlock the door. Continue holding the 9-Volt in position until the door unlocks.
Note: If you remove the battery before the door unlocks, you will need to re-enter your user code
Remove the terminal cover
Hold the battery to the terminals. You will hear beeping to signal you can open door.
Press the battery firmly against the terminals, it will beep 3 times. Keep holding the battery firmly and enter your User Code and press the lock button to unlock
