I have a 1993 400 SEL and the key entry system does not work at least not all the time. The keys were originally designed to use a battery that is no longer avaliable because of enviromental reasons. The replacement battery from the dealer is a style 357. Does this have anything to do with the operation which is now sporadic? I have three keys, two regular keys and one 'Valet' key. The two regular keys are the ones with replacement batteries and don't work most of the time. Can they be repaired?

CALL YOUR LOCAL BENZ DEALER. ITS POSSIBLE THAT THEY CAN GET NEW ONES

I have a '95 S600, and just bought a new battery for my entry key from the local dealer after I bought the car a few months ago. I don't remember how well the old battery worked, but I do know that the remote access button must be pressed for a few seconds to open or lock the doors, and I always have to be fairly close to the car for it to work. I'm wondering of all these transmitters require such close distances to work (less than 10 feet)?

I BELIEVE THE BOOK (MANUAL) SAYS 21FT.

IF THIS STILL DOESN'T WORK, CHECK THE DOOR HANDLES TO SEE IF THE RED/GREEN SENSOR AREAS ARE FADED...
