My passat has trouble opening the central locking. The garage replaced key 12 months ago.
The key has now intermittently stopped unlocking ( locks ok) but I can unlock it using the other key.
a garage reported that the alternate key had failed yo unlock for him .
he used the backup method of opening the door.
The new key cost £400 + service charge to register it to the car.
Is this a common problem?
any DIY method of fixing?
