Springs at the top of the shaft keep the pins in place.
How a door handle lock works.
The two most common types of locks in a home are simple key locks in a doorknob and deadbolt locks.
The pins are placed in pairs with one on top of the other.
The key to match the particular lock lifts the pins to the correct height to allow the latch the part that protrudes into the door frame to be pulled back against the spring allowing the door to open.
The latch bolt is connected to the latch which protrudes from the edge of the door and engages the door frame preventing the door from opening.
When the door is unlocked a part called a tang is resting fully inside of the cylinder.
Inside the cylinder are all the parts that work together with the key to lock or unlock the door.
When it s locked the cylinder engages a series of spring loaded pins which keep the cylinder from turning.
Round pocket door locks often fit in a standard 2 1 8 hole allowing you to use an existing door for a pocket door.
A door handle controls a door by manipulation of a latch a mechanical fastener that joins two or more objects together.
When you insert a key the uneven edge pushes the pins upward to fit the key s height in that location within the lock body.
Key locks contain a small cylinder that runs down the middle of the doorknob and into the door.
A standard doorknob lock set consists of a pair of knobs one on each side of the door that are connected through the door by a spindle and held together by mounting bolts.
Most square pocket door locks feature a simple lever that flips out from the door edge and acts as a finger pull to slide the door out of the pocket.
Cylinder lock body the cylinder or lock body is the part of the door lock where you insert the key.
Each pair rests in a shaft which is drilled through the cylinder and the housing around the cylinder.
The spindle runs through the latch bolt which is inside the door perpendicular to the spindle.
