doors wont open....

I have a 1990 sedan deville, I can only open the drivers door.the rear doors wont open or the passenger door, the door lock cylinder does not work on the passenger side either the key just spins around.the rear doors have manual locks lets put it this way Ive tried everything under the sun to no avail.Ive tried the electic locks in front I hear the selenoids working.......I dunnnno.

Gotta get the trims off and look for disconnected lock rods, or try and slim jim them open for better access to get the trims off.
