they are a special key thing. Actualy, if you can get under the truck there is a black tub thingy leading to where you put the thing in to lower the spare tire. it might take a bit of effort, but you can turn that and it comes off, should be about 1/4 turn. then there is a little metal thing there that the key goes into, it pops out with a pry bar or something. It's easier to get rid of the damn things then to get a new key, and besides that if you get any mud or anything in there they key don't work till it's cleaned out. I actually should get rid of mine, I'll try to get pics then if I can. Stupidest concept I've ever seen. The ones on the newer trucks are not bad.
