I bought the car few weeks ago. Previous owner gave me only one keyfob and it's in a bad shape. First I tought only missing 2 button so there is no problem. When I open it up, I realize there are several missing component other than just two button. I can find replacement key fobs but all of them coming with their own transponder chip which I don't need. And What I am most curious if I get one of those keyfobs can I resync the new bought keyfob with my car without programing the key because I will be using my own working transponder ?
