Starting the car without a key.. is it possible?
The new Smart key will need to be coded to your car's ECU to work. That's a dealer only operation. I'm afraid you'll have to bite the bullet and get the car to the dealer.
BTW, I don't think $500 will put much of a dent in the cost of your own SDS.

Good luck.
The key needs no battery to start the car.
B. Have you checked the cars battery?
C.What good will spending $2500 on an sds do if you don't know what the diagnostics mean and how to resolve the issue?
D. charge the battery
E. after that disconnect it and try to reestablish comm with the key when you re hook it up.
F. if that fails tow it to an indie shop with an sds.They can order a special one time use das key to reprogram the system if that is the issue.
G. No, there is no way to start it without the key. the key generates a rolling code to the das.

Kevin, I was referring to a factory SDS bought from MB (if you could). There have been several 'reverse-engineered' systems on eBay using electronics from asia and a pirated copy of an older version of Carsoft International's software. Some as cheap as $100 without a laptop. Those seem to have dried up awhile back but I did see a post recently from a guy in Canada. As for the post you referred to it's from early 2008 so maybe that one's not available. But ohlord's right that having an SDS isn't going to solve the problem if one doesn't have the knowledge and experience to exploit it's use.
You might try shopping around for a transport service. Maybe someone who needs the work will negotiate a better price.
Good luck.
The Carsoft software ($100-$200) is unlikely to help you reprogram your car key. There are "shared" copies of SDS software that are available, but are well into the thousand dollar range.
