If you have any questions or are having difficulty programming your HomeLink buttons, refer to the HomeLink web site at: www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ACC position when programming HomeLink. It is also recommended that a new battery be placed in the hand-held transmitter of the device being programmed to HomeLink for quicker programming and accurate transmission of the radio frequency.

1. Position the end of your hand-held transmitter 1-3 in (2-8 cm) away from the HomeLink surface, keeping the HomeLink indicator light 1 in view.

2. Using both hands, simultaneously press and hold the desired HomeLink button and hand-held transmitter button. DO NOT release until the HomeLink indicator light 1 flashes slowly and then rapidly. When the indicator light flashes rapidly, both buttons may be released. (The rapid flashing indicates successful programming.)
NOTE:
Some devices may require you to replace Step 2 with the cycling procedure noted in "Programming HomeLink for Canadian customers and gate openers" in this section.
3. Press and hold the programmed HomeLink button and observe the indicator light.
A second person may make the following steps easier. Use a ladder or other device.
Do not stand on your vehicle to perform the next steps.
4. At the receiver located on the garage door opener motor in the garage, locate the "learn" or "smart" button (the name and color of the button may vary by manufacturer but it is usually located near where the hanging antenna wire is attached to the unit). If there is difficulty locating the button, reference the garage door opener's manual.
5. Press and release the "learn" or "smart" button.
6. Return to the vehicle and firmly press and hold the trained HomeLink button for 2 seconds and release. Repeat the "press/hold/release" sequence up to three times to complete the training process.
HomeLink should now activate your rolling code equipped device.
7. If you have any questions or are having difficulty programming your HomeLink buttons, refer to the HomeLink web site at: www.homelink.com or call 1-800-355- 3515.
