Repairing a Rim Deadbolt Lock

Rim deadbolt locks are installed on the surface of a door rather than within the body of the door. No lock holes are required, but the lock still provides extra security above that of a key-in-knob lock. When hinge screws come loose from hinges, the entire door shifts, causing the bolt and strike to become misaligned. Loose hinges and a lack of lubrication can lead to malfunction of a rim lock. With a little maintenance, you can restore the lock to proper working order.

Instructions

- 1
  Check the bolt and slide to make sure the gap between the two sections lines up with the gap between the door and frame.
- 2
  Examine the door hinges for any loose screws. Remove and replace the screws with longer screws in the same diameter or slightly larger. If the top of the bolt housing is leaning further toward the strike than the bottom, tighten the top hinge screws until level. If the bottom of the bolt housing is leaning toward the strike, tighten the bottom hinge screws until level.

  Spray the bolt lightly with a silicone-based lubricant and move the slide back and forth to distribute the spray.
- 4
  Turn the thumb turn counterclockwise until it loosens from the assembly. Remove the thumb turn and spray the inside of the screw hole lightly with silicone-based lubricant. Screw the thumb turn back into place clockwise.
- 5
  Remove the trim screws, insert the key into the lock and turn it 90 degrees. Remove the trim plate. Brush any debris from the lock interior with a toothbrush. Spray lightly with a silicone-based lubricant. Replace the trim and screws.
- 6
  Remove the strike plate mounting screws and reposition so the bolt slides into the strike without resistance.
