The factory anti-theft system is built in to the computer system on this van. Why not have a good shop scan the engine computer, the body computer etc to find the code and fix the problem? It could just be a worn key or the transducer that goes around the ignition lock etc. A good shop should be able to isolate the problem, I have fixed these problems several times and I mentioned the 2 most common problems i.e. key and transducer.
here are some shops:
