Hi Paul I take it the batteries has gone flat if so re-new them once this is done put the key in the ignation and turn the car on and off 4 times quickly if you do this right the light on the clock will stay on then press the second botton and keep it pressed for about 4 seconds then let go. the light on the clock should flash if so then the job is done.
if this isen't your answer then put the key in the drivers door and lock the door and open it then try in the ignation. If this doesent work try the same on the passanger door.
Good luck
Jim
