so what i did was i spliced into the lock wire since its a 12v pulse.. then i connected it to the piezo buzzer and grounded the other wire on the piezo and its in my driver fender.. so as long as i hit the button and hear one beep then its locked, if i click it and i hear nothing then its unlocked. but thats just me as long as i get one beep to confirm i locked my car thats good enough for me.. i might be converting to full keyless 2012 style soon no keys to open or start the car..
