The HomeLink® compatible transceiver in your vehicle has 3 buttons which can be programmed to operate 3 different devices. Refer to the programming method below appropriate for the device.

Programming the HomeLink®

Keep the indicator light on the HomeLink® in view while programming

If the HomeLink® indicator light comes on but does not flash, or flashes rapidly for 2 seconds and remains lit, the HomeLink® button is already programmed.
Use the other buttons or follow the “Reprogramming a HomeLink® button” instructions.

If programming a garage door opener, check to see if the garage door opens and closes.
If the garage door does not operate, see if your garage transmitter is of the Rolling Code type. Press and hold the programmed HomeLink® button.
The garage door has the rolling code feature if the indicator light (on the HomeLink®) flashes rapidly for 2 seconds and then remains lit. If your transmitter is the Rolling Code type, proceed to the heading “Programming a rolling code system”.
Programming a Rolling Code system (for U.S.A. owners)
If your device is Rolling Code equipped, follow the steps under the heading “Programming the HomeLink®” before proceeding with the steps listed below.
Refer to the operation manual supplied with the garage door opener for the location of the training button.
Following this step, you have 30 seconds in which to initiate step 3 below.
If the garage door opens, the programming process is complete. If the door does not open, press and release the button a third time. This third press and release will complete the programming process by opening the garage door.
The ceiling mounted garage door opener motor should now recognize the HomeLink® transceiver and operate the garage door.
