HomeLink onboard systems can be found on dozens of vehicle types around the world. These programmable remotes are most commonly synced to garage door opener units, but they also can be used to control your home's gate opener. Programming your HomeLink system can be done in just minutes from your driver's seat, as long as you have your gate opener remote or access to the motor, and you can have the system ready to use immediately.
Enter the car with your gate remote and press and hold the two outer buttons on your HomeLink onboard system.
Hold for about 20 seconds and release the buttons once the LED light on the system begins blinking.
Turn your key in your ignition to the "Acc" position.
Hold your gate remote three inches from the onboard system and press and hold the button you wish to program on your onboard system.
Repeatedly press the open button on your remote every two seconds until the LED light on the system begins flashing more rapidly. Release the button on your onboard system.
Press and hold the button you just programmed on the onboard system again until the LED light glows solid.
