I have lost my only key to my 2004 Crossfire. Every site I have contacted has come up empty, does anyone have a possible source or supplier I can contact? Rich in Ohio

 

Josh Chase at the Mercedes Swap Shop. He will need your car's ECU and SKREEM. There is almost no other alternative, many locksmiths will charge your a "trip charge to see what I can do", then bill you and tell you they can't help.
Same goes for dealers, the corporate channel from your dealer back to MB is gone, so there is no factory support.

Call Josh.

Best Info.

 

Pizzaguy is correct. You are going to need to remove the ECU from under the hood (easy and there are Youtube videos - Josh has one posted I believe).

You are going to need to drop the lower dash to remove the instrument cluster (not so easy but also nothing to get overly spooked about). To do that you'll want to watch these 2 videos in this order and as long as you are dropping the dash you may as well do the sticky key fix at the same time because it is not a matter of if but when the ignition is going to give you problems. The SKREEM removal video picks up nicely from where the Sticky Key removal video ends.

I had already done the sticky key fix so going back in to get the SKREEM out for Josh took me about 45 minutes watching the video a couple of times and then watching parts of it in the car when I was doing the work.

There's a reason Paul's sticky key upload has been viewed 55k times and the SKREEM upload 30k times.
