I HAD A BUMPER COVER INSTALLED ON MY 2000 CL500. I WENT TO PICK MY CAR UP AND IT WON'T START. CHECKED THE FUSES AND THEY ARE GOOD. THEY DID HAVE TO CHARGE MY BATTERY THOUGH. OPEN THE DOOR AND THE DASH LIGHTS UP, PUT THE KEY IN AND TURN IT AND THE CAR WON'T DO ANYTHING. IT SAYS REMOVE KEY. WHAT THE HECK DID THEY DO OR UNPLUG?
