- Every remote you want to keep, ready to re-pair right after
Step by step
Step 1: Find the learn button on the motor unit.
Step 2: Press and hold it for about six seconds, until the LED next to it goes out. Then let go. Remotes and keypads are now erased.
Step 3: On a yellow-button opener, myQ accessories like a wireless door sensor are kept. To clear those too, hold the learn button again straight away, until the LED goes out a second time. Neither hold removes the opener from your myQ account; that takes the black adjustment button, held until the opener beeps three times.
Step 4: Press each old remote. None of them should move the door now.
Step 5: Re-pair the remotes and keypad you're keeping, and re-train your car buttons.
Still not working? Here is what it usually is.
- The LED never went out. Keep holding until it does.
- An old car button still works. Re-train it from the car, or clear it using the car's own reset.
- The learn button doesn't respond at all, which points to a logic board problem.

Common Questions
We just moved in. Should we really do this?
- Yes. You don't know how many remotes the previous owners, their family, or their contractors still have. Erasing them takes a minute and is the single best security step for a new house. Set a new keypad PIN at the same time.
