If the key fob and the central locking buttons on dash don’t work but the boot and fuel filler door still lock/unlock (you can hear them clicking when the fob buttons are pressed) but the doors do not and you get two delayed beeps then you need to sit in the car with the doors closed DON’T press the brake pedal and turn the ignition on and off with the start/stop button 4 times then press the unlock buttons on all fobs you want to re-sync then turn the ignition on and off again and the fobs should now work again and the mirrors will fold in when locked. Hope this helps.
