Things to Check
- Remote battery
- Keypad battery
- Whether the wall control still works
- Whether the opener has power
- Whether controls need to be reprogrammed
One Control or All Controls?
If one remote stops working but the wall control still operates the door, the issue may be limited to that device.
When the Opener May Be Involved
If all controls fail or the opener behaves inconsistently, the opener system may need service.
