The battery went flat in my 2000 Mercedes SL500 (R129).
Now the remote control part of the key doesn't operate the central locking.

I replaced the batteries in the key and tried different methods of coding it to the car.
Nothing works.

There is an infra-red receiver in the door, no lights in the interior mirror.
Anyone know the answer?
