Hi, tried to lock my car using the key yesterday, but it would only lock the drivers door ,and nothing else. When using the alarm fob ,or the lock button inside the car, all works fine.
Once the doors are locked via alarm fob, i can unlock them all with the key.
Any ideas what could've happen ? It used to work fine until now
