When to Change the Code
Change the keypad code when you move into a house, after a contractor, house sitter or ex-roommate no longer needs it, or if you've ever shared it more widely than you meant to. Skip codes like 1234, the house number or a birthday.
If the Keypad Stopped Working
- Replace the battery. Most keypads run on a 9-volt or a couple of AAA batteries under the cover, and cold weather drains them faster.
- Check the lock button on the wall control inside. When it's on, the keypad and remotes won't work.
- Reprogram it. A keypad has to be paired again after a new opener or logic board, or if someone cleared the opener's memory.
Programming a Keypad Yourself
On most LiftMaster and Chamberlain openers, press the Learn button on the opener, then within about 30 seconds enter your new four-digit code on the keypad and press Enter. When the opener lights blink or you hear two clicks, it's set. Other brands work differently, so check the label on the opener or the manual.
When to Call
If a new battery and reprogramming don't do it, the keypad may have failed, may not match your opener, or the opener's receiver may be the problem. Zach can test it and replace the keypad with one that works with your opener. If your remotes are giving you trouble too, see remote setup.
