vauxhall cosra 2007 wont open have changed fuse still wont open with the fob
Try fitting a new battery in the fob. Best done at a dealership and it's usually done free of charge except for the small cost of the battery. Well my Volvo and Hyundai dealers do. Some fobs have a small light on the fob when you pres open. Is yours lighting up. If not, it is even more likely the fob battery.
