You want to buy a replacement ignition tumbler from a dealer and either have it installed or install it yourself. Yours is worn out, and I'm told that if it becomes so worn out that your key gets stuck in there or it won't turn at all anymore, it has to be drilled out, which is a pain in the you know where. You'll need the car's title or registration as well as your drivers' license to order this part, if your dealer is like my dealer.
