Q: Ignition key not working - 1987 Mercedes-Benz 420SEL

asked by on

I am having trouble with my car key. I cannot get it to work in my ignition, and the car has been sitting in the garage for a couple of months. I can open the trunk, the doors and the glove compartment. Do you have any suggestions, solutions?

It’s quite likely the battery is dead, and all electrical functions are inoperative. All of the locks have mechanical actuators. A certified technician from YourMechanic can replace your battery at your home or office and get you on your way.
