Parts of door lock

Before you can repair a door lock, you need to be conversant with the anatomy of the door lock. They include:

  1. Lock body: This is called the cylinder where the key is inserted. The cylinder engages several spring-loaded pins to lock it. Thus, the cylinder doesn’t turn.
  2. Latch: A piece of metal protruding into the door frame serves as the latch, or bolt, within the door to keep it closed. A latch can either be a Deadbolt or Spring bolt. A knob or supplementary key located on one side of your door is used to activate the deadbolt. These are said to be safer than spring-bolt latches. The clips that hold the spring bolts compress to release the latch and operate automatically as the door shuts.
  3. Metal strike plate: The frame has a metal strike plate on it. As a result, the latch is moved from the cylinder into the box for added durability.

The following equipment is required for general door lock repair:

  • Graphite power tube
  • Screwdriver
  • Pair of plier
  • Hammer
  • Lock de-icers
