My wife's Honda Jazz 2nd Generation (2005/55) has recently been written off in an accident. She has now purchased a 3rd Generation 2008 (58) however this only came with one key. I understand that getting a 2nd key cut for the car is pricy, I've just realised that we have 2 of the keys for the old car still kicking around the house. To be honest these look identical and I was wondering if they can be reused? I have the key code for the new car.
