If you are referring to the child-safety locks that prevent the door from being opened from the inside - they are located on the door jamb of the door itself and look like little black switches that stick out. On mine they are on the back edge of the door itself located below the level of the window glass area.
I have a 1988 Honda civic lx and the rear passenger door has a child lock on it and I don't know how to get it open?
Hint: Have you checked the child-proof door lock button located in the door's door jamb to make certain it is in the unlocked position?

CHECK TO SEE IF THE "CHILD LOCK MECHANISM " IS ENGAGED
You open the back hatch door and pull the panel away from the latch and push down on the lever to the lock the lock will then pop open and you can shut the hatch
Pull the inner panel and actuate the latch manually.
On the inside upper frame of the rear passanger door when open there are 5 bronze pegs that make contact with the door when closed, if these become dirty the electrical contact will not lock the rear door. Take fine grade sandpaper or steelwhool and shine them up, close the door and try it again.
