Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Programming Common Universal Transmitter Codes
- Press and hold the two outer HomeLinkĀ® transceiver buttons, and release only after the indicator light begins to flash (after 20 seconds). Do notĀ hold the buttons for longer than 30 seconds and do notĀ repeat this step (Step 1) to program a second and/or third hand-held transmitter to the remaining two HomeLinkĀ® transceiver buttons.
- Position the end of your hand-held transmitter 3-8 cm (1-3 inches) away from the HomeLinkĀ® transceiver buttons while keeping the indicator light in view.
- Simultaneously press and hold both the HomeLinkĀ® transceiver button to be programmed and the hand-held transmitter button. Do not release the buttons until step 4 has been completed.Ā NOTE:
Some gate operators and garage door openers may require performing an alternative procedure for this step. If needed, perform the Step 3 procedure below in CANADIAN PROGRAMMING/GATE PROGRAMMINGĀ .
- The HomeLinkĀ® transceiver indicator light will flash slowly and then rapidly after the HomeLinkĀ® transceiver successfully receives the frequency signal from the hand-held transmitter. Release both buttons after the indicator light changes from the slow to rapid flash.
- Press and hold the selected programmed HomeLinkĀ® transceiver button and observe the indicator light. If the indicator light illuminates constantly, programming is completeĀ
and the device should activate when the button is pressed and released.NOTE:
To program the remaining two buttons, begin at Step 2Ā of "Programming HomeLink Transceiver Codes". Do not repeat step 1Ā .
If the indicator light blinks rapidly for two seconds and then turns illuminates constantly, continue with "Programming" steps 6-8Ā to complete the programming of a rolling code equipped device (most commonly a garage door opener).
- 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.
- Firmly press and release the "learn" or "smart" button (The name and color of the button may vary by manufacturer).NOTE:
Step 8 must be initiated within 30 seconds.
- Return to the vehicle and firmly press and holdĀ
the programmed HomeLinkĀ® transceiver button and release after two secondsĀ
. Repeat this "press/hold/release"Ā
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 programming.
The HomeLinkĀ® transceiver should now activate your rolling code equipped device.
To program the remaining two HomeLinkĀ® transceiver buttons, begin at Step 2Ā of "Programming HomeLink Transceiver Codes". Do not repeat step 1Ā .
