Reprogramming Common Universal Transmitter Codes

To program a device to the HomeLink® transceiver using a button previously trained, follow these steps:

1. Press and hold the desired HomeLink® transceiver button. DO NOT  release the button. The indicator light will begin to flash after 20 seconds. Without releasing the HomeLink® transceiver button, proceed to step 2.
2. Position the end of your hand-held transmitter 3-8 cm (1-3 inches) away from the HomeLink® transceiver button while keeping the indicator light in view.
3. Simultaneously press and hold both the HomeLink® transceiver buttons that you want to program and the transmitter buttons. Do not release the buttons until step 4 has been completed. 
   NOTE: Some gate openers and garage door openers may require you to replace this reprogramming Step 3 with procedures noted in CANADIAN PROGRAMMING/GATE PROGRAMMING .
4. The HomeLink® transceiver indicator light will flash slowly and then rapidly after it successfully receives the RF signal from the transmitter. Release both buttons after the indicator light changes from the slow to the rapid flash.
5. Press and hold the just programmed HomeLink® transceiver button and observe the indicator light. If the indicator light stays on constantly, reprogramming is complete  and your device should activate when the button is pressed and released.
   NOTE: If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with "Reprogramming" steps 6-8 to complete the programming of a rolling code equipped device.
6. At the garage door opener receiver (motor-head unit) in the garage, locate the "learn" or "smart" button. This can usually be found where the hanging antenna wire is attached to the motor-head unit.
7. Firmly press and release the "learn" or "smart" button. The name and color of the button may vary by manufacturer.
   NOTE: There are 30 seconds in which to initiate step 8.
8. Return to the vehicle and firmly press, hold for two seconds and release  the reprogrammed HomeLink® transceiver button. Repeat the "press/hold/release"  sequence a second time, and, depending on the brand of the garage door opener (or other rolling code equipped device), repeat this sequence a third time to complete the reprogramming.

   The HomeLink® transceiver should now activate your rolling code equipped device.
