Here's what I've found before on the key fob codes:
AUTOMATIC (ROLLING) LOCKS
This is the "Lock when the vehicle is going 15mph" feature. This feature can also be disabled through the EVIC.
The rolling locks feature can be toggled ON/OFF by using the DRB IIIt only.
HORN CHIRP DISABLING / ENABLING
This controls if you want your Libby to beep the horn when locking via the keyless entry. * Reports indicate that this does not work for 05 mdoels.
To DISABLE (cancel) the horn chirp feature,
Press and hold the transmitter LOCK button for four to ten seconds.
While pressing the LOCK button in, press the UNLOCK button.
Release both buttons.
To ENABLE the horn chirp feature, repeat the above procedure.
OPTICAL CHIRP (FLASH) DISABLING / ENABLING
This controls if you want your Libby to flash the hazard lights when locking/unlocking via the keyless entry.
To DISABLE (cancel) the optical chirp feature,
Press and hold the transmitter LOCK button for four to ten seconds.
While pressing the LOCK button in, press the TAILGATE RELEASE button.
Release both buttons.
To ENABLE the optical chirp feature, repeat the above procedure.
TAIL GATE RELEASE DELAY
The liberty can be set to pop the tailgate instantly when you press the button, or require it to be pressed and held for it to open
Press the UNLOCK button for four to ten seconds.
While pressing the UNLOCK button, press the TAIL GATE RELEASE button.
Release both buttons.
This will toggle between PRESS AND HOLD and PRESS (no delay).
UNLOCK SEQUENCE
When unlocking the liberty, you can choose between unlocking drivers door first or unlocking all doors simultaneously.
Press and hold the transmitter UNLOCK button for four to ten seconds.
While pressing the UNLOCK button in, press the LOCK button.
Release both buttons.
This will toggle between Driver door first and Unlock all doors function.
Hope this helps.
