Door Lock Replacement – What Are the Different Parts of a Door Lock? A broken door lock can make your home an easy to target for burglars. Change your locks can be an inexpensive way to improve security without making your doors unusable. Many locks come with a cardboard model that you can use to wrap around the edges of your door to ensure it fits properly. This will stop you from buying the wrong lock. The Cylinder The cylinder, also referred to as the lock body is the primary component of the traditional mechanical door lock. It houses a collection of spring-loaded pins that lock the door even when no key is placed into the hole. When keys are put into the doorknob the uneven edge presses upwards on the pins inside of the cylinder, fitting them to their correct positions. Once the pins are seated they allow the bolt, also referred to as the latch to move forward, and then engage the door's inside. The bolt extends from the cylinder and into an opening in your door frame called the box. The box is designed to fit the bolt tightly so that it won't be pulled open easily. The bolt is pulled back by a clip spring once the door is closed. When you turn the handle, a spindle is engineered to rotate inside the cylinder. After it has completed its rotation the slanted side of the bolt retracts into the doorframe. The bolt rests on the cut-out portion of the doorframe, and closes the door until you are required to reopen it. A faceplate is an inside metal plate that is fixed to your door on either side of the hole that is used for the deadbolt. Its purpose is to safeguard your locking mechanism from damage that could result from the repeated removal and insertion of your knob. Installing a new lock?

Faceplates can accommodate many different designs, but they have to be positioned properly, balanced and fixed that aren't simple tasks if compared to the simplicity of the chuck. A typical faceplate has many mounting holes, in this case three holes positioned at a 120-degree spacing to accommodate the screws for mounting the workpiece 18 of FIG. 2. The screw holes are made using an interchangeable insert 16 or directly into the body of the faceplate. A portion between the faceplate has a stepped area that provides an index mark to pinpoint a specific location on the blank workpiece. The stepping area has also been designed to be abrasion-resistant to ensure that the fastener doesn't harm the chisel that you use to cut it. The body's surface of the faceplate has different characteristics from the surrounding region and machining into this region warns the turner to possible contact with a fastener and gives the turner time to react. Screws used to fix to a faceplate should have a little free space in the screw hole. When the screw is firmly seated onto the glue block, there should be no space between it. This may permit the block during rotation to shift. A screw with a greater gauge will also seat more securely on the faceplate. The screw should be inserted into the middle of the screwhole to prevent the possibility that a screwhead might be in contact with the workpiece.
