#1 please make sure you provide full details. What year is your van?

Do the headlights come on, or any accessories whatsoever?
You would have a security light if the anti-theft system was engaged.
Replacement BCMs need to be programmed to your vehicle.

Got it going. Disconnected battery and connected battery cables to drain all power. Reconnected battery and car started, locks work etc. I think the computers got screwed up somehow and needs to be rebooted. Thanks!
