Lost key problem

If you only lost the keys and the rest of it was working good you will want to do one of two things. One would be to contact an automotive locksmith, they can use information on the car and from the factory to make new keys that fit the original locks as well as program them into the system. You can usually do the same thing at a dealer, however they will require you to get the car to them while the locksmith will come to you. In both cases they can delete the old keys from the cars memory so that if someone were to find them they would no longer work.
