HELP! MY REMOTE FOB FOR MY 1999 CLK HAS STOPPED WORKING. IT STARTS THE CAR HOWEVER THE LOCK/UNLOCK NUTTONS DON'T WORK. I CHANGED THE BATTERY THINKING IT WAS THAT BUT IT GUESS IT WASN'T. I WANT TO KNOW IF ANYONE OUT THERE KNOWS HOW TO FIX THIS.

ALSO I JUST BOUGHT A NEW REMOTE FOB ON EBAY AND WANT TO PROGRAM IT. CAN ANYONE HELP ME DO THIS? THANKS ONCE AGAIN AND I HOPE TO HEAR FROM SOMEONE SOON.

maybe it's not a key problem?

central locking got PSE pump too.

 

If you live in the USA you will have to take your new key to a Benz dealer along with your registration and a copy of your drivers license and they will send it to MBUSA for programing. As far as your old key FOB, when you put in the new batteries did you put them in correctly that is positive sides facing up? and did you make sure th contacts weren't bent over the plastic inside and not contacting the battery when you slide the batteries and holder back together? this happend to me and until I figures out what I did the key didn't work, also reinstall the battery, but bend the metal contact down carefuly so they make good contact with the batteries and one last thing, did you buy the correct battery?
