if your afraid of locking the keys in just get a couple of cheapies made and put them in a magnetic holder somewhere. Did that with our 09 pick-up. Was told you couldn't get a key without dealer but not so...   The key you get will unock the door but not start the truck. It also helps to hurry up and put the right key in the ignition if security is on. Otherwise the horn might blow till you start it... At least you won't get locked out.

  let our onstar expire but it stills tells me to air up the tires.
