You need to sync your keys.. Try inside the car pointing at the rear view mirror cluster..Hold button for 60 secs.. then exit lock door remotley the unlock trunk remotley..Try see what happens..

I dont think this is a fix, but to resync a remote on a 92, point it at the door, push button for a few seconds, and then within 30 seconds lock or unlock door with a key. The sensors are in the door and trunk handles.
