Step1: Batteries
Once inside the room, open the back of the lock using the Allen wrench, as seen in the photo, counter-clockwise screw to open the cover.
- Disconnect the wire attachment from the top of the battery block.
- Replace the batteries, making sure their orientation is correct; take one out at a time and place the new one in exactly the same direction as the original.
- Reattach the wire connector, which you should hear a gentle noise after completing the wire attachment if it's working.
- Place the battery box on the ledge
- Put back the cover and screw it back in.
