Okay, so got in the car last night to drive home and no problems, car opened as usual with the unlock button on the key. Got home, tried to lock the car with the lock button and nothing. Red light still flashed on the key, but doors would not lock. Tried the unlock and boot buttons too but still nothing. I'm thinking its the key battery need replacing but would the red light still flash if it was flat?
If it is the battery, which one do I need to get hold of and how quickly do I need to change it over?
Thanks!
