Hi all, I have two identicle keys same serial numbers one works the central locking one doesn't, but the red L.E.D light on both key fobs lights up and acts the same denoting the battery in the key is okay, is it possible one key has lost its code and one hasn't, and if so is this a dealer only job or is there any one else that will deal with the problem local to Nottingham. Thanks for any help. Andy.
