1. Locate the garage door opener in your Highlander. It is usually mounted on the ceiling of the garage or on the wall near the garage door.
2. Remove the cover of the garage door opener to access the controls.
3. Press and hold the "Program" button until the LED light begins to flash or changes color. This indicates that the opener is now ready to deprogram.
4. Press and release the "Open" button on the garage door opener for one second. The LED light may momentarily flash again.
5. Repeat Step 4, until all garage door remotes, and other external controllers are cleared from the memory of the system (Max 4). The opener LED stops flashing or changes color back to normal when cleared successfully.
NOTE: The steps required to deprogram your garage door opener can vary depending on the specific model. If you are unable to program or deprogram your door opener using these instructions, consult the garage door opener's owner's manual or the garage door manufacturer for further assistance.
