Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Park outside the garage, clear the door's path and switch vehicle power on as the manual directs.
- 02
Press and release the desired HomeLink button.
- 03
Hold the original remote 3–7 cm away and press it until the HomeLink indicator changes from flashing amber to green.
- 04
Test HomeLink; slow green flashing generally completes fixed-code learning.
- 05
For rapid green flashing, press the opener's Learn or Smart button and within 30 seconds press-hold-release HomeLink for two seconds up to three times.
Important limits
- Keep the car outside the garage during setup because the door can move unexpectedly.
- Use the garage-opener manufacturer's instructions and safe ladder technique at the motor housing.
- Erasing all HomeLink memory removes every programmed device.
Quick checks.
- ✓If the indicator does not turn green, verify the original remote works and vary its position within the specified distance.
- ✓If rapid green flashing remains, repeat the motor Learn step and the timed HomeLink presses.
- ✓If the opener's Learn window expires, reactivate it rather than continuing to press HomeLink.
