I've one keyfob which doesn't work (2006 Alfa GT). Battery is fine, took it to a key place and they confirmed that it was transmitting when the buttons were pressed. They said I need the Code Card to pair it to back to the car. the Dealer kept this and then went bust several years ago. They only clue to the failure is that the metal keyring bit of the fob broke, and the remaining bit fell inside the keyfob and rattled around, next day the key wouldn't unlock the car. I wonder did the metal bit short something on the little circuit board, enough to mess up the codes being transmitted so it's not recognised, but it still transmits the UHF signal, hence the keyshop got a reading? I'm not stuck as I have the other key, but it will be costly if I have to pay the main dealers for a replacement code card when mine was never supplied when the car was new. I see the ecu program AlfaOBD can reprogram keys, but it mentions something about a password as well as the code card PIN. Full version of AlfaOBD is about £32, code card on top of that is I dont know how much, but If I need a password that only the main dealers have I've wasted my time. Any suggestions?
