You can start it by putting into program mode...try to start, then turn it to off..,,then turn it to on (not start)..leave it on for 15 min...turn it to off for 2 min..and start..
This will reset the signal from the bcm to the pcm of the car.
you most like ly have a problem in the start switch key reader...It has to be replaced as a unit
Or it could be your bcm or pcm...very very expensive... try this first... If it does not work off to the dealership..don't even try to give this to a garage to fix. Gm has the software to reflash your computer.

First the sensor in the rear gearbox may be bad or corroded for sensing wheel speed. Also the engine wiring harness may be falling apart. From 1991-1995 the US made MB use biodegradable material on the wiring. When the insulation cracks you get shorts in the system. The same wires are in your EHA on the air inlet area. Check and replace as needed.

I had the same problem in my 2004 CLK 500. I took it to the dealer and they said it was shorting out and it needed a new alarm siron. The repair cost was $450. What a rip off.
