My friend at work says his wifes spare key now wont unlock the car with the plip part, using the blade he can unlock the car and he can start the car using the blade, but he cant open the doors using the plip (or lock using plip), he has changed the battery and that didnt help ?, anything else to try ?, will the fob need reprogramming after a battery change ? (i heard it can be reset by leaving key in ignition ?
cheers
