Do the dash cd, wipers & horn work with one key and not the other?
Batteries in the key have nothing to do with this. The key is inductively energised by the EIS.

W203 key problems
Glyn, thanks for your reply, yes the chrome key is fine, the spare will unlock/lock remotely, start the engine & drive but nothing else is energized, non of these work- rev counter, wipers, horn, cd etc, I've tested the IR output with a camera & it unlocks the car, it's like a get-you-home mode - any ?

The key for some reason is not accomplishing a complete handshake with the EIS. Very, very strange. First time I've ever encountered this. I'm sure a new key will fix it - reprogramming the old key might. You talk about a Chrome key? Is the other one plain black plastic & are both original? C32's to SA did not have chrome keys so I wonder if it is a replacement. Do you know the history?
It is almost as though the spare key has been programmed as a service key except the things it is cutting out make no sense. Maybe in Europe some cars second keys were programmed as minimum function service keys.
Anyway - a new key or reprogrammed key will fix it but it is a bit of a pain with Benz security. The dealer will have to send it in with all the checks that you are the owner of the car.
Good luck!

Yes - it could be a valet coded key but cutting wipers would seem stupid.

W203 key problem
Thanks for the suggestions guys!
Think I'll go down the old key or new key reprogram route, my local MB money vacuum shouldn't try it on this time, the last visit was a battle over the cash register.........they had the car 4 times before managing to fit new pads n discs, the original price was £716.00 all in..... I actually paid £275.00 after various requests to see the MD & asking whom was going to take responsibility for not having checked the spares had arrived prior to calling me to drop the car into them 4 times in 2 months!!!!! GOOD RESULT eventually!
