Which lock is this? The Yale Real Living T1L is a touchscreen keypad deadbolt with no keyhole. Its model number is YRD120.

How do I know the batteries are low? The low-battery light on the keypad flashes red, and your alarm panel or the Alarm.com app may show a low-battery warning for the lock.

Can I change them myself? Yes. It takes about five minutes, and the lock doesn’t need to be paired again afterwards. Your codes stay as they are.

You’ll need: four new AA alkaline batteries. Don’t use rechargeable or heavy-duty batteries, and don’t mix old and new.

Steps

1. Unlock the door first. The bolt must be pulled back (unlocked) before you put new batteries in.
2. Go to the inside of the door. The batteries are behind the cover on the inside part of the lock, not the keypad outside.
3. Take the battery cover off.
4. Take out all four old batteries and put in four new AA alkaline batteries, matching the + and − marks.
5. Don’t press the small reset button while the batteries are out or going in. Holding it as the batteries go in erases every code, including the master code.
6. Put the cover back on.
7. Test it: lock and unlock it from the keypad, then from the Alarm.com app. The app may take a few minutes to show the lock as normal again.

Locked out with dead batteries? Hold a 9-volt battery against the two terminals below the touchscreen, either way round. That powers the lock long enough to enter your code and unlock the door. Then change the AA batteries.
