Remote lock/unlock transmitter
 

I've dropped it several times, and the plastic is starting to flake off. Are those expensive to replace? I'm assuming one would need to be ordered. I'm afraid if I drop it again it may not work. I had the ignition switch replaced, so that's the only way I can unlock the car.

if the inside isn't damaged, and you just want to change the plastic cover, try ebay, you will have to buy the whole thing but you can always just take it apart and put yourPCB in.

hope this helps
