Hi. Having major issues with my central locking.

The key fob wont unlock or lock the car doors or boot but it still activates the wing mirrors when I press the lock/unlock on the key fob. So im assuming Key Fob not broke. Also spare key does same.

when inside the car with ignition on the button on the inside of the drivers door does not lock or unlock the car either. Totally dead

Any help much appreciated.
Cheers.
Rob
