I did... and you saw it at our get together in NH a few months back.It is a pita! No one to my knowledge has managed to do this with the factory key fob but I think aftermarket systems are capable to it. Someone here has added an aftermarket remote that accomplishes this if I recall.
Hey Eddie, did you install an aftermarket alarm when you did the all unlock/lock setup on another key fob?I did... and you saw it at our get together in NH a few months back.
The key (pun intended) is to remotely use the center console all-lock/all-unlock button wiring to connect to a cheap keychain remote control. My setup also allows you to lock the van with the engine running, because the aforementioned button does it.
