I cant get the 2005 CL65 ket to turn or recognize in the ignition. I put a brand new battery in key fob. It is just telling me to "Do not forget Key" as soon as I open the door and that is the only message I am getting. The car has been sitting for awhile and hooked battery back up and something is not right. Any help would be much appreciated. The car was running and driving fine before it sat for a few months.
