For security, you will want to perform this function again to erase all button frequencies before transferring vehicle ownership. You do not need to repeat this step to program or reprogram any of the individual HomeLink buttons. Do this by pressing and holding the two outside buttons I and III – releasing only after approximately 20 seconds, when the light in the HomeLink symbol begins to flash. Prior to programming any of the buttons for the first time, you will want to erase any factory-set default codes. Then switch on the ignition, but do not start the engine. HomeLink can be programmed in just one minute, after which all functions can be used immediately. The three HomeLink ® buttons can be programmed to replace loose remote control devices, such as those for garage door openers or property gates.
