hyundai - central locking not working - adam f
car is a 1997 2.0SE hyundai coupe.

the central locking works when i put the key in doors.
the key fob works - light comes on when press buttons. put a new battery in just in case the old one didnt have enough power for car to pick up signal.

the car seems not to be picking up signal, even when standing next to it.

does anyone know how i can fix this. would a diagnostic machine be able to reset something to fix the problem.

I wouldn't be surprised if Hyundai use a rotating code system, and the car & key are out of sync. A lot of cars are resettable by turning the ignition on and pressing the button. However, every manufacturer is different - a main-dealer might be able to point you in the right direction without charging (unless of course it's a problem with the key, in which case they're not cheap).
