I am using C6 latches in my car and billet outer door handles with the button inside the grip part.

There is no lock or unlock on those latches though. I'm using the security disable function on my Infinity Box to disable to latches when the system is armed. I'm running the back up release cable to my door lock though so I still have a way to get in the car should the battery die or something.
