i dont think c5s have the fob your talking aboutIt sounds like you don't have your option set to unlock the doors when the car is turned off.
You have to go into the DIC and go thru the options to see if it's turned on or off.
It also sounds like you have the fob set to auto lock the doors when you are in range with the fob.
You should have a slide switch on your fob to turn that on and off.
but i could be misreading it:huh:
