Keys
WARNING
Leaving children in a vehicle with the ignition key is dangerous for many reasons. Children or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move.
The windows will function with the keys in the ignition and children could be seriously injured or killed if caught in the path of a closing window. Do not leave the keys in a vehicle with children.
The key is used for the ignition and all door locks.
The key has a bar-coded key tag that the dealer or qualified locksmith can use to make new keys. Store this information in a safe place, not in the vehicle.
See your dealer if a replacement key or additional key is needed.
Notice: If the keys get locked in the vehicle, it may have to be damaged to get them out.
Always carry a spare key.
If locked out of the vehicle, call Roadside Assistance. See Roadside Assistance Program (U.S. and Canada) on page 13‑8 or Roadside Assistance Program (Mexico) on page 13‑10.
With an active OnStar subscription, an OnStar Advisor may remotely unlock the vehicle. See OnStar Overview on page 14‑1.
