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.Google+

the car dosent star whit the send key and dont open the doors.
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.

Wont stay running. Anti theft. Cant get a key from dealer. They have all been given out and lost. Any help would be wonderful
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!

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.
