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 button that you want to train and the hand-held transmitter buttons. Do not release the buttons until step 4 has been completed. 
   NOTE:

   Some gate operators and garage door openers may require you to replace this Reprogramming Step 3 with procedures noted in the "Gate Operator/Canadian Programming" section.CANADIAN PROGRAMMING/GATE PROGRAMMING 

4. The HomeLink® transceiver indicator light will flash slowly and then rapidly after it successfully receives the frequency signal from the hand-held transmitter. Release both buttons after the indicator light changes from the slow to the rapid flash.
5. Press and hold the just trained 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 (most commonly a garage door opener).

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.
