Door Lock Replacement – What Are the Different Parts of a Door Lock? A damaged door lock 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. Many locks come with a cardboard template which you can use to wrap around the edges of your door to ensure that it is properly fitted. This will prevent you from purchasing the wrong lock. The Cylinder The cylinder, also known as the lock body is the most important component of a traditional mechanical door lock. It contains a series spring-loaded pins that hold the door shut when there is no key into the hole. When a key is placed into the doorknob the uneven edge presses upwards on the pins inside of the cylinder, fitting them into their proper place. When the pins fit, they alow the bolt, also referred to as the latch, to move forward and engage the door's inside. The bolt extends from the cylinder and into the box, through a hole is made in the door frame. The box is designed to fit the bolt snugly so that it won't be easily pulled open. A clip spring holds the bolt retracting when the door is closed. When you turn the handle and the spindle inside the cylinder rotates. When it's done rotating, the slanted end of the bolt retracts into the doorframe. The bolt rests on the carved-out portion of the doorframe, and keeps the door closed until you are required to reopen it. A faceplate is a metallic plate that attaches to the inside of your door, either side of the deadbolt hole. Its function is to shield your locking mechanism from damage that could be caused by the repeated insertion and removing of your knob. If you're installing a brand new lock, make sure that the faceplate is aligned with the hole in your door frame and that it's securely attached to the plate as well as the bore of your latch. If you're replacing a door lock be sure that the deadbolt fits correctly by sliding it into the strike plate's opening. Once you're done, screw the strike plate and the core of your new lock into place. Do not over-tighten as this can damage the latch or prevent it from fitting into its groove. You can test your new lock by rotating the key until it is locked position. If you find any issues like a loud deadbolt or loose latches it's recommended to replace the old lock with a new one. The Faceplate A faceplate is a huge flat plate that is attached to the headstock of a lathe to hold the workpiece. It has a variety of screw holes through it where the screw thread enters from the back and winds into the wood. Faceplates can accommodate many different shapes but in general they need to be placed properly, balanced and fixed and balanced, which aren't easy tasks if compared to the simplicity of using an chuck. A typical faceplate is equipped with a number mounting holes. In this instance three holes are located at 120Adeg intervals to receive the mounting screws 18 in FIGURE. 2. These screw holes are manufactured using an insert that can be interchanged or directly into the faceplate body. The faceplate has an incline in the middle, which serves as an index mark to indicate an exact location on the blank workpiece. The stepping region is abrasion resistant so that the fastener won't damage the chisel used to cut it. The surface of the body of the faceplate has distinct properties from that of the surrounding area and machining into this area alerts the turner to possible contact with a fastener and gives the turner time to react. Screws used to secure the faceplate must have a little free space in the screw hole. There should be no space left behind the screw after it is tightened on the glue block, since this may allow the block to move when turning. It is also an ideal idea to use a heavier gauge screw since it will be more secure on the faceplate. The screw should pass through the center of the screw hole to avoid the possibility of a screw's head coming into contact with the workpiece. The Strike Plate The strike plate is one of the most vital components of your door lock. The strike plate is what stops the bolt from sliding when you shut the door. The strike plate helps to strengthen the lock and stop intrusions by putting force against the jamb and latch. A strike plate is a thick metal plate that is inserted into the doorjamb (the vertical portion of the frame) with a hole that allows the deadbolt or latch to pass through. When the cylinder is turned the bolt will shoot out of the strike plate into the doorjamb, and it stays closed. There are various kinds of strike plates available, depending on your needs. If you need a strike plate that is compatible with your specific lock it will be listed with the product information. In other cases, most strike plates are the same and work with all standard locks and latches. Standard strike plates are fitted with ovular screws as well as an “C”-shaped piece that functions as a washer. They are often used on doors that have round corners. They are available in a variety of sizes to match the door. For additional security, you can opt for strike plates with no lip and is designed specifically for deadbolts. This is a great option for areas that must be secured quickly, for instance stairs. This is a great option when you need to protect items or documents inside your home. Installing a box strikeplate will also improve the security of your doors. replacing window locks increases the thickness of the strike plate, and also strengthens it. This makes it more difficult to break in through the deadbolt or latch and is often required for commercial doors equipped with a security lock. Spray a lock lubricant on the strike plate if it isn't aligned with the latch bolt. If this doesn't work, you'll have to adjust the strike plate by drilling new holes in the screw and widening the hole for the catch. Be careful not to make many adjustments to the strike plate as repeated and extreme changes can weaken it to the point where it's no longer effective. The Deadbolt A deadbolt lock is a sturdy bolt made of metal that secures your door to the doorjamb's frame. As opposed to a spring-latch that is used in doorknobs which can be used to loid (jimmied) using credit cards or professional tools such as latch slips, deadbolts are locked with the use of a key, thumb turn, or electronically (in the case of keyless and smart deadbolts). They are more user-friendly and require less maintenance. They also provide better protection against forced entry methods such as kick-ins. The bolt extends through an socket or hole in the door jamb, which is then reinforced with a strike plate to provide additional security. The bolt must be at least 1 inch long to make it more difficult to pull off the door. It is also recommended to select deadbolts that have an ANSI rating, which shows how secure the lock is. The strike plate also helps to hold the cylinder in place. There should be three holes that run along the bolt: one, in the center, connects the facepiece and the cylinder. The two other holes are to the left and right of the central hole. These are the holes where screws go to attach the cylinder to the bolt. The screws should come standard with the new deadbolt. Certain locks come with decorative covers that snap on the facepieces. Follow the directions provided by the manufacturer to ensure that they are properly installed. Selecting the best lock for your home requires contemplating your lifestyle and the level of security you require. Single cylinder deadbolts, the most common lock type can be found on a variety of exterior door. Keyless deadbolts are safer however they can be difficult to operate. Smart deadbolts let you lock and unlock the bolt using voice commands or a mobile app. A professional locksmith can assist you in determining which type of lock is appropriate for your home and will install or change the lock. Upgrading your front-door locking system is a cost-effective option to boost the security of your home. For an added layer of security, you could think about adding a reversible or double-cylinder deadbolt to the outside of your door, too.
