Hi,
Advice needed. I have a 2002 ML 500. It has about 40K miles on it. My kids have been using it and we are now down to one key. The transmitter does not work. I have to use the key to open the doors. When I get in I turn the key and all of the accessories work. The radio and lights are all on. However there is no crank when I fully turn the key. It is just dead. Nothing. A day or two later I will try again and it will work fine. Im confused. The other night the car was dead again. I pushed it a few feet to move it closer to the curb. When I tried again it worked. Do you think it could be the key or the battery?? Please let me know. thanks.
