Most inexpensive DIY key copy for 2005 Porsche Cayenne?
I was wondering the least expensive DIY route to copy keys from an existing working key.
Can I get all of it done with just with only these things and nothing else (no other hardware, no extra software purchase)?
1. the vvdi programmer for $435
2. the vvdi2 basic for $529
I'm willing to pull the bcm out and solder what I need to.
