"No start" Due to Anti-Theft System Fault on Mercedes-Benz ML320

A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.

I lost the keys and went to a dealer for new keys. One worked and one did not. I went to my local mechanic who works on MB's and he replaced the ME computer described as a Remanufactured ME 2.0 Control Unit (945$) for $1400. The dealer then order new keys saying the old ones were not correct. Did I need the new computer? It was remanufactured according to the mechanic who said he paid $745 for it.
Went out to start it one cold winter morning and it would not start. Starter would engage but as soon as it would kick over it would stop. It was the key. Cost me $100 to diagnose, $141.50 for the key and chip, and $52.50 to program it. That is for one. But it works!

My car is stored 6 months of the year. When it wouldn't start, I was told I had to replace the module ($1400). I did not do this. With some research, I determined that the problem was with the electronic system of the car not recognizing the key code. I was lead to believe that the problem occurs when the vehicle is inactive (no one has ever confirmed this). I do know that this can occur for people when the battery is changed out. I have two fobs with electronic locks etc. and both would start the car, but it would not stay running. Fortunately, I also have a simple, valet-type key and it starts the car and everything works fine. I now carry around one large fob and the valet key, one to run it and one to lock it. New coded keys are $300 each . . . .I'll make do with what I have.

When battery went dead, car would only start for a few seconds. Everything eventually locked up and had to have it towed. Keys then did not work thereafter. Even with new keys still problems.
