Door Lock Replacement – What Are the Different Parts of a Door Lock? Faulty door locks could make your home a to target for burglars. Changing your lock is an inexpensive way to beef up security without making your door unusable. A lot of locks come with a cardboard template that you can wrap around your door edge to ensure it will fit correctly. This will help you avoid buying the wrong lock. The Cylinder The cylinder is the primary element of a mechanical door lock. It is made up of a set of spring-loaded pins which keep the door shut even in the event that no key is inserted into the hole. When a key is placed into the doorknob the uneven edge pushes up on the pins within the cylinder, allowing them to fit into their proper place. When the pins are place, they allow for the bolt (also called the latch) to move forward, connecting to the door's interior. The bolt extends out of the cylinder and then into the box, a hole that is drilled in the door frame. The box is designed in a way that the bolt can't be easily pulled out. The bolt is pulled back by a clip spring when the door is closed. When you turn the handle, the spindle inside the cylinder rotates. The inclined end retracts into the door's frame when the spindle is finished rotating. source website rests in the carved-out portion of your doorframe, securing the door shut until you need to open it again. A faceplate is a metal plate that is attached to the interior of your door, either side of the deadbolt hole. Its job is to protect the locking mechanism from damage caused by your knob's continual insertion and removal. If you're installing a brand new lock, make sure that the faceplate lines up with the hole in the door frame and that it's securely fastened to the plate as well as the bore of your latch. When replacing locks on doors make sure the deadbolt is seated correctly by sliding it into the the strike plate. After you're done, screw the strike plate and the central part of the new lock into place. Do not tighten too much because this could cause damage to the latch or stop it from fitting into its groove. It's a good idea test the new lock by turning the key while it's in the locked position. If you find any issues like a squealing deadbolt or a loose latch, it's best to replace the lock with a brand-new one. The Faceplate A faceplate is a huge flat plate that attaches to the headstock of a lathe to hold the workpiece. The screw thread is inserted into the wood through the series of screw holes. A faceplate can support various shapes, but in general they need to be placed properly, balanced and fixed and balanced, which aren't easy tasks if compared to the ease of using a tool chuck. A typical faceplate is equipped with a number mounting holes. In this case, three are positioned at 120 degrees intervals to accept the mounting screws 18 in FIGURE. 2. These screw holes can be manufactured using an interchangeable insert 16 or directly into the faceplate body. The faceplate features an incline in the middle that acts as an index mark to locate an exact location on the blank workpiece. The stepping area is resistant to abrasion, so that the fastener will not harm the chisel used to cut it. The surface of the body of the faceplate has different characteristics from the surrounding region. Machining into this region alerts the operator of a possible contact with a fastener, and gives the turner time to react. Screws used to hold a faceplate into place should be of a size that can fit inside the screw hole, leaving only a tiny amount of play. There should be no space left behind the screw when it is tightened on the glue block, since this may cause the block to shift during turning. It is also an ideal idea to use a heavier gauge screw because it will seat more securely within the faceplate. The screw should also pass through the center of the screw hole to prevent the possibility of the screw head coming into contact with a workpiece. The Strike Plate The strike plate is among the most vital components of your door lock. The strike plate is what prevents the bolt from slipping when you shut the front door. The strike plate helps to reinforce the lock and stops intruders from breaking in by applying force against the jamb and latch. A strike plate is a heavy metal plate that installs in the doorjamb (the vertical part of the frame) with a hole that allows the deadbolt or latch to be able to pass through. When the cylinder is turned, the bolt is released from the strike plate into doorjamb and stays there. There are various kinds of strike plates that are available, depending on your needs. If you require strike plates that work with your specific lock it will be listed with the details of the product. In other cases, most strike plates are similar and will work with most standard latches and locks. Most standard strike plates have Ovular screw holes as well as an “C-shaped” piece that acts as a washer. They are often employed on doors with rounded corners. They are available in a variety of sizes to match the door. You can add extra security by using a strike plate with no lip that is designed for deadbolts. This is a great option in areas where security needs to be achieved quickly, such as staircases. This is an excellent option for those who want to secure documents or equipment in your home. Installing a box strikeplate will increase the security of your doors. It adds thickness to the strike plate, and also strengthens it. This makes it harder to gain entry through the latch or deadbolt and is often required for commercial doors equipped with security locks. Spray a lock lubricant on the strike plate if it isn't aligned with the latch bolt. If this doesn't work, you will have to modify the strikeplate by drilling new screwholes and widening your catch hole. It is best not to make any adjustments to the strike plate. Repeated and extreme adjustments could cause it to become ineffective. The Deadbolt A deadbolt is a steel bolt that connects the door to the doorjamb frame. In contrast to spring latches used in doorknobs that can be loided (jimmied) with credit cards or professional tools such as latch slips deadbolts are locked by keys, thumb turns or electronic (in the case of smart and keyless deadbolts). They are simpler to use and require less maintenance. They also provide better protection from forced entry techniques like kick-ins. The bolt extends through a hole or socket inside the doorjamb which is strengthened by a strike plate for additional security. The bolt should be at a minimum of 1 inch long to make it difficult to remove from the door. You should also choose deadbolts that have an ANSI rating, which indicates how secure the lock is. In addition to securing the bolt the strike plate also helps to hold the cylinder in place. There should be three holes through the bolt. One located in the middle connects the facepiece to the cylinder; the other two are to the left and right of the central hole. The screws are inserted into these holes to attach the cylinder and bolt. The screws should be included with the new deadbolt. Some locks have decorative covers that snap on the facepieces. Check the instructions of the manufacturer to ensure that these are installed correctly. Choosing the right lock for your home requires considering your lifestyle and what security level you need. Single cylinder deadbolts are the most popular lock and can be found on a variety of exterior doors. Keyless deadbolts can be more secure, but they are more difficult to use. Smart deadbolts let you lock and unlock them by voice commands or a mobile application. A professional locksmith can help you decide which type of lock is appropriate for your home, then install or replace it. Upgrading your front-door locking system is a cost-effective method to increase the security of your home. To add a layer of protection, consider adding a reversible or double-cylinder deadbolt on the inside of your door, too.
