There is a program fob menu on your DIC, page through it and it explains what to do.
The early C5s have a passive mode. There is a pendulum switch in fob and walking towards car automatically unlocks it, while walking away locks it. You do NOT have to push buttons. New C6s brought back this feature. If you lock your keys in the car, with the passive switch on, you can just shake the car and it will unlock the doors.
Oh, stand by car and push both the lock and unlock buttons for 5-7 seconds, if horn honks you have reset fob. Sometimes this works, reprograming always works (as long as battery and fob are okay).

I just walked out to the garage.. held lock and unlock.. and, almost jumped out of my boots when the horn beeped. Works great now. That's crazy.. but, great.
