The ignition key is for the ignition only. If you need a new ignition or door key, contact your dealer who can obtain the correct key code. Also, see "Roadside Assistance" in the Index for more information. NOTICE: Your vehicle has a number of features that can help prevent theft. But you can have a lot of trouble getting into your vehicle if you ever lock your keys inside. You may even have to damage your vehicle to get in. So be sure you have extra keys. If your vehicle is equipped with the OnStarR system with an active subscription and you lock your keys inside the vehicle, OnStar may be able to send a command to unlock your vehicle. See "OnStar" in the Index for more information. The ignition and door keys don't have plugs. Your dealer or Buick Roadside Assistance has the code for your keys. The door key is for the doors and all other locks. 2-5
