I bought a Porsche Cayenne s for 700 with no key. When I found a local person willing to cut and program a new he believes he may have corrupted the kessy module. I don't live near a dealer and my current attempts at getting a new haven't worked yet. Is there a way to get a new key and kessy module without going to the dealer or do I just have to call it a day and get ready to write a check? I've already pulled one kessy module from a junkyard and bought one off eBay. Neither worked.

 

Speak with Speedo Solutions, Tom I believe is his name, but he can tell you if you are missing a step and he can even perform all services needed. Also he has an aftermarket key option that I very much like and would endorse.
Please be conscious of his time when asking questions, he is very nice and very busy.

 

Maybe these guys can help?
