MY Dad has a '95 Econoline Van and he doesn't know what he's done but the front 2 doors are all that the remote will unlock now. It's a handicap model for my Mom and now he has to climb back their to unlock the doors.
He's a very good mechanic but hasn't had time to check it out yet.
He's says it acts like he has activated some sort of child lock protection.
Any ideas??

 

Did you check the owner's manual?
