Battery is fine in the key fob. Even put a new battery in just for the heck of it. If you stand close to the van and press the button, sometimes the hazard lights will flash one time and you can barely hear a little noise (click) like the door is trying to lock. But no go.

Same goes if you are in the cab and press the dash power lock button. You can barely hear something trying to happen (click), but no go.

So, it's not the key fob.

No bad fuses either.

Add it to the list of strange things wrong with the Babe.
