Is it possible to reprogram a crossfire key, and if so can the “blade” be replaced and cut to fit the ignition?

 

The original key can be reprogrammed, what's your problem with the key ?

 

I’m buying a scrap crossfire for parts. It has a key with it. I only have one key for mine, curious if it can be reprogrammed to work with my car.

 

No!

 

I think the parts car fob can be recognized by your car, but the key and the security chip cannot - the key probably doesn't have enough meat on it to be re-cut, and the chip is a one time programmable eprom. You can buy a blank key on ebay for a few dollars, I believe the size is H64, and you can buy the programmable chip for a couple of bucks (I bought 10 for about $20, I don't remember the part number). The problem is finding a locksmith who can clone your key for a reasonable price.

You can get a extra key by sending in your existing key to the MSS, 5 working day turnaround at this link : https://themercedesswapshop.com/?page_id=211

 

You have a few options.
The best is to send your working key out to either Needswings.com or MercedesSwap Shop.com.
The next option is a memnber in the market place in our forum. Look for his add.
The last option is to find a local automotive locksmith as mentioned above, who can clone your chip and make a valet key.
That's what I had done here in New Jersey. The locksmith could not make a working key fob. When I get some spare money I'll send mine out to get another working fob.

 

to added to this, ANY KEY THAT BEEN PROGRAMMED ONCE CAN NOT BE REPROGRAMMED TO ANOTHER CAR.

but yeah us at The MSS can get you squared away

 

Has anyone ever optically digitized a key into to a dxf format ? This file can then be used to generate a program for a cnc milling machine that could cut a new blank. This is probably how the keys were initially cut.
