Hi all,
Yes I've been off the forums for a while onehundred80, unfortunately I sold my Crossfire. But, I did not run into trouble with the push to start, it turned out really well.
For the bypass module I used the Directed Electronics universal bypass module.
(It's only about $12 right now)
The system I used was the push to start by Advanced Keys, it worked flawlessly and I had no reliability issues.
The hardest part was probably opening up my key to get the transponder out and placing the transponder in the bypass module. Quite honestly it was an easy install. Although it was very convenient, a few months later the novelty of the push to start wore off and it became "normal" to use I guess. I don't regret doing it at all though, it was very convenient, PM me if you have any questions. I will try to stay as active as I can now that I know there's at least one person interested haha!
