how to reset remote key fob for Mercedes SL 320
C200 key fob problem
You normally do not have to reprogram the key when you replace the battery. If you do you will have to contact your VW dealer.
You'll probably need to have this done at a dealership.

Put the key in the ignition and turn the key 2 clicks to the On position and press and release the lock button on the fob. Then press and hold the unlock button on the fob 5 times and then release. This will reset the fob for your Mercedes.

Take it to your dealership they would be the one to help you with that.
your key fob can only be programed by the local gm dealer.

It can cost as much as about 300 dollars to re-key the average car. This varies depending on the type of ignition and the type of key.
