Just been to get a key cut for my car and found out that i need a transponder with a megamos chip? chip number 48? no idea what any of this means anybody know where i can get this chip from and where i can get it programmed and for how much? sorry about all the questions i have no idea about any of this. Its for a remote central locking fob with the key attached to the fob but because i dont have the transponder i cant get my car to start. Any help at all would be great.
