Remote door lock works but the door lock button does not?

Answer:
If the remote locks the door properly that tells me that the wiring and the lock solenoids are operating OK. I'm also taking it for granted that the switch you spoke of is the door lock switch on the drivers door. Does the passenger door switch work properly? If so, then you probably have a bad switch on the drivers door.
(IMPROVE) You can remove the door lock mechanism from the panel and gently pry open. Carbon build-up is common on the switches. Use a pencil eraser to remove the carbon and ensure the switch functions properly. Re-assemble.
