OK, so I lost my keys today and I still have my spare set. I was wondering how I can go about reprogramming the FOB so that whoever out there who has my other set of keys can't unlock my car with the FOB. I thought I read that you can do it youself. And how much does the dealer charge for this service?

 

The specific instructions can be found easy though search.
