While I haven’t been able to actually use the secondary CAS key programmed to the original CAS, it looks to be new(unused). I was expecting to receive an “EBay Special”, and was genuinely surprised with the product. From the dealership, it’s $250.00 ( not programmed). I would’ve purchased the upgraded ECU (DME), but my state, Texas, has very strict, and specific requirements for emissions testing. After consulting with the technician at ECU-Pro, he, honestly, wasn’t sure if it would pass. He did, however, take a day to format a program that would work, but the decision maker of the household was unwilling to be the beta subject, even after an offer of a 10% discount, which is huge!!! If you’re from California, Texas, or New York, they DO have a solution. I’m now spending an additional $400.00 over their price at dealership. Call them!!! Speak to a tech. It’s a clear line of communication. Sincerely, Ryan Humphrey
