I've recently fallen in love with my "new to me" 2004 CTT.  Now that I've taken care of all of the mechanical bits I'm turning my attention to some minor cosmetic things.

 

#1 on my list is that I only have one single lonely key.  I'm always nervous about losing it, so I've been prowling eBay for a couple of spare remotes.

 

I understand that I'll have to cut the blank and have someone with PIWIS program the key. 

 

My question is: Can a "used" key fob be programmed to my vehicle?  Or must I purchase a new, virgin, fob?

 

Sort of a second question: Is there an alternative to the "switchblade" style key?  One that has a remote door lock button, but the blade is fixed?

 

By the way, mine Cayenne has (non-functional) keyless 'enter and drive' (or whatever it's called), if that matters.  I'll fix it, but one problem at a time...

 

Thanks for your advice!

Probably a violation of myriad rules of etiquette, but I'm answering my own question.  Hopefully this will help the next owner with the question, "Can I program a key fob previously used on a different car to my own Cayenne?"

 

Nope.  I've consulted my dealer and two independent mechanics I respect.  They say that, while it's technically possible, it's so difficult that they wouldn't undertake the task.

 

So much for all those cheap used fobs on eBay....
