Warning
Leaving children in a vehicle with a Remote Keyless Entry (RKE) transmitter is dangerous and children or others could be seriously injured or killed. They could operate the power windows or other controls or make the vehicle move. The windows will function with the RKE transmitter in the vehicle, and children or others could be caught in the path of a closing window. Do not leave children in a vehicle with an RKE transmitter.
The key, inside the Remote Keyless Entry (RKE) transmitter, is used for the driver door.
To remove the key, press the button near the bottom of the transmitter, and pull the key out. Never pull the key out without pressing the button.
If it becomes difficult to turn the key, inspect the key blade for debris.
See your dealer if a new key is needed.
Contact Roadside Assistance if locked out of the vehicle. See Roadside Assistance Program.
With an active OnStar or connected service plan, an OnStar Advisor may remotely unlock the vehicle. See OnStar Overview.
