How to Program a 2011 GMC Terrain Ignition Chip Key Transponder
Step by Step How to Programming Instructions:
1. Enter the vehicle and ensure all doors are closed. The anti-theft light will start blinking.
2. Insert the master key into the ignition and turn it five times, leaving the key in the ignition on the fifth insertion. The anti-theft light will go out.
3. Open and close the driver’s door six times.
4. Remove the master key from the ignition. The anti-theft light will stay on. Verify that the security light on the information display is solid, indicating that the car has entered programming mode.
5. Insert the new transponder chip key. Watch the security light blinking for about 60 seconds.
6. When the security light goes out, your new key should be successfully programmed.
7. Remove the newly programmed key from the ignition cylinder and insert the master key. Start the engine. This will take the vehicle out of programming mode.
8. Turn the key off and insert the newly programmed key again to start the car.
