If you need to change the code on your keyless door lock, follow these steps:
Press and release the [Unlock] button on your remote. The Lock/Unlock indicator will flash to indicate that the system is in programming mode.
Press and release the [Lock] button on your remote (this will set a new code). Your unique code will be programmed into memory automatically; if it’s successful, you’ll hear a chirp from your garage door opener. If this doesn’t happen, try repeating this process until it works (it sometimes takes more than one attempt).
