Dear JPO,
Not sure exactly what you are asking, but I assume that you want to change the unlock setting to open all doors at once. If so, here is the excerpt from another thread that gave me the answer that worked for me:
TorontoTCH 
vbmenu_register("postmenu_90082", true);

Re: Smart Key Auto Unlock
According to my Canadian manual page 40, it says" Hold the LOCK, ALARM and TRUCK buttons on the remote together for 5 seconds then release." You should hear 2 beeps after.
Even though this was from the Canadian manual, it worked for me first time.
If this is NOT what you are looking for, please clarify.
Good luck!
