Hi. I have just purchased a 2003 crossfire automatic coupe. The remote key fobs are the 2 button type with swing-out key... One key and fob works but is falling apart, the other is good condition and key works fine but the remote control does not work. Fitted new batteries and LED lights but does not operate central locking. Any ideas how to program or re sync this. Tried the "push button twice quickly and insert in ignition" technique but sadly did not work. Please help many thanks
