Read the Manual, its in there. I did it when I first got it.

 

put the key on and hit the trip button till it says #2 it should work

 

I perfer the silent mode...I'm not trying to draw attention to myself when I go in 7-11...Just seeing the Hummer takes care of that.

Remote Keyless Entry Feedback
This feature allows you to program your remote keyless
entry feedback to a preferred setting.
To set your choice for this feature, perform the
following steps:
1. With the engine off, turn the key to LOCK. Do not
remove the key from the ignition.
2. Press and hold the lock and unlock buttons on the
remote keyless entry transmitter at the same time.
Hold both buttons until the DIC display shows
the current remote keyless entry feedback mode.
3. To view the next available mode, press and hold
the reset stem for approximately two seconds.
Release the reset stem and press and hold again to
view each mode.
4. Once the desired mode is shown on the DIC

choice. The DIC display will then clear.

The following are the available modes:
RFA 1 (default): This mode flashes the parking lamps
when you press the lock or unlock buttons on the
remote keyless entry transmitter.
RFA 2: This mode flashes the parking lamps and
sounds the horn when you press the lock button on the

flashes the parking lamps when you press the unlock
button on the remote keyless entry transmitter.
RFA 3: This mode flashes the parking lamps and

feedback. There will be no feedback when you press
the lock or unlock buttons on the remote keyless
entry transmitter.

 

I prefer the chirp. That way I know that I locked it. Mine was like that when I picked it up, but I think that it can be set with the arrow button on your steering wheel.
