Battery type
The maker's manual says which battery a keypad takes and how to change it. Follow the maker's instructions.

We give no battery life figures. The maker's manual covers what it states.
A way in that works
Keep a working way to get in, such as a key, in case a battery or keypad fails. The maker's manual says what backup a given lock has.
What we do not cover
We give no wiring, reset, or bypass steps.

FAQ
General information only. No keypad, lock, or code can guarantee that a door will stay secure or that a break-in will not happen. Keep codes private, change any code you have shared, and follow the maker's instructions. Before you put a keypad or lock on a door people use to leave a building, check with your local building or fire official. In an emergency, call 911.
