I'm assuming you mean "from the inside" since you would use your key from the outside. I'm not sure about the '92, because I have a '94, but on my van on the inside of the slider door there is a small rocker lever just above the door opening latch. This rocker causes my slider door to lock and unlock. Hope this helps!
This answer is correct!!
Begin by removing the inside door panel on your 1997 Plymouth Grand Voyager. Remove the door lock linkage. Remove the door lock retaining bolts. The door lock will come out.

I would rather have a sliding door. A sliding door offers unparalleled convenience and efficiency. Sliding glass doors are also better because they are easier to lock from the inside and you can see out of them because they double as a window.
maybe its broken
The child lock could be on.
Try turning the key to the on position then back to off 4 times, then press the driver's door lock button. You should hear a chime if it works.
drill the lock out
If the sliding door on the 1999 Mercury Villager will not stay open, check for something that is not allowing the latching mechanism to lock into place. Make sure that the door is all the way back so that it can lock in.
To lock one side of a sliding mirrored closet door, a person can insert something in the channel for the slide mechanism that will stop movement of the door. A screw will accomplish this if it is left only halfway screwed in.
Try cleaning the spring loaded contact points between the door and the door jam. Both the points and the door contact get dirty. I've cleaned them with a good pink pencil eraser and very fine sand paper. Good luck.
Here's a video that I've included below, that shows you how to repair the door lock actuator on the sliding door of a 2001-2007 Chrysler Town and Country.
