Wha't wrong with yours? If it's the cylinders, you can get the door and ignition fairly cheap at the dealer. A locksmith can rekey for you if that's the problem.
If you buy new locks, you can rekey them - you'll have to if you get the new cylinders. The new cylinders do not come with wafers.
Either way - whatever you do, you'll need to get those little chrome faceplate/door thingys, they're at the dealership or at a locksmith's A 'smith may also have the cylinders, if you're lucky.
Somehow I doubt anyone here with good locks will part with them, and any locks they're willing to part with won't be too useful for you. Just a guess...
