Turn the ignition key to the "I" position and remove the electrical plug in the back of the ignition switch. The switch should be exposed now that the cowl and instrument cluster have been removed. You will access the plug from the top of the ignition switch and cylinder assembly. Another way to troubleshoot your Mercedes ignition switch problem is by using a spare key. Insert the spare key into the Electronic Ignition Switch (EIS) and attempt to start the vehicle. If the vehicle starts, the problem could be with the original key. Replace the battery in the key fob or consider having a new key programmed for your vehicle. Remove the two plastic covers surrounding the steering column and the transponder ring and forcefully strike the lock face using the wooden dowel and hammer. After each striking insert the key and try to turn. Do not use contact cleaner, it is a drying agent. Use Lock-Ease as I originally suggested. Popular Mercedes-Benz Services We Offer.

First time this started was about two weeks ago, after about an hour driving all dash lights disappear and car goes into park and won’t drive while the engine is still running.
