How to program key fob?

First of all, you need to confirm whether your key remote can be programmed by yourself or you need a professional to do it. Second, if your vehicle supports self-programming, you can follow the key remote programming tutorial to do the programming yourself. If your vehicle needs to be programmed by a professional, contact your local locksmith or dealer who will do the programming. Most importantly, you need to make sure that the car key you purchased is compatible with your car, and if the programming fails because of the wrong purchase, I really feel sorry for you.
