How Do I Know If My Opener Uses Rolling Code?

Look for:

• “Security+”

1. Press and hold desired Car2U button.
2. Hold until LED flashes slowly.
3. Press Learn button on opener.
4. Return to vehicle.
5. Press Car2U button repeatedly until door activates.

Consult your vehicle manual for exact procedure.
