Hello, I am new to this site and just purchased a 2013 C250 sport. Comes with keyless go, as I got a printout at the dealer, has the black sensor on driver handles, and regular sensors on all other doors. The issue I'm having is that the smart key works to unlock/lock doors and roll down windows, but the keyless entry part of it doesn't work. When i grab the handle, the car won't unlock. I've tried switching out the battery. Is there anything else I can try before taking it to the dealer? I've searched the forum but couldn't find anything. Thanks!
