I have a 1997 E320 with two keys. Just the other day, I could not lock the doors with either key. Figuring it was the batteries, I changed them in both and yet it still will not lock. I can start the engine and drive no problem, but I cannot lock the car!
I have tried turning the key one click (not turning the engine on) then removing the key and that did not work. Not sure how to resynch, but was hoping to avoid removing the battery terminal. Any ideas???
Thanks in advance.
Oh, and if you happen to see my car, please don't steal anything since my doors will be unlocked!!!
