After the cylinder has been removed, you can measure from the screw hole in the middle of the cylinder to edge of the handle plate on the inside of door. Make sure you include the thickness of the plate, as well. You can also take a measurement of the length of the threaded shaft on the new cylinder to determine the size. After determining the length of the cylinder you can install it inside your door. Start by drilling a hole in the door. This is where the handle will go. It should be a little bigger than the diameter of the new cylinder. Afterward, connect the handle inside or knob to the new handle and make sure it passes through the latch's spindle and operates smoothly when turned. When replacing a deadbolt, you should also upgrade your strike plate. The strike plate is a piece metal mounted to the doorjamb, which locks into the deadbolt when a key is pushed in. It is essential to replace the strike plate with a more secure version that is less difficult to break. Choose a strikeplate that has a reinforced metal structure to resist kick attacks. Make sure to use screws that are 2.5-3 inches long to ensure they penetrate deeply into the doorjamb. Design The lock cylinder is part of the front door lock that you utilize to open or close the handle. It has pins that move into position when you insert the key. When it comes time to select the correct lock cylinder, you'll need to know some things. It is crucial, for instance to determine the length of your cylinder locks that you have in place so that you can order the correct size. It is also important to consider any door furniture, such as handles and escutcheons. Euro cylinder locks are common in homes, and they're offered in a variety of styles. Some are double cylinder locks, which offer security from both sides of the door. They are often used on doors that require more security than conventional locks, as well as in commercial buildings with a few. If you're in the market for a new lock, check that it's British Standards approved and meets the following requirements: Anti-Snap: A burglar may try to snap a cylinder by applying pressure to the exterior of the door. To avoid this the lock must have a thin sacrificial line that's cut into the body of the cylinder. Anti-Drill – Some burglars attempt to drill into the lock and break into homes. To prevent this from happening, a cylinder must have pins made of steel that has been hardened. If you're looking for a new cylinder, then you should also consider whether it's anti-drill. This will prevent a burglar from tearing the plug off by drilling into it with a power tool. If you've decided to purchase a new cylinder lock, you'll need to gather the necessary materials for installing it. This includes a screwdriver that's appropriate for the job and pliers and a hammer for added grip. It is also recommended to have oil to ensure that the mechanism is operating smoothly. Be aware that changing the lock on a uPVC can be a challenge. If you're not confident in doing it yourself, you should contact a locksmith or a specialist to get help. Keyway The keyway is the shape that the interface between the pins of the cylinder and the key has. The key has a series of grooves and ridges that extend along the length of its “blade” and, when inserted, these align with the cutouts in the pins of the cylinder. The cylinder will only rotate if it recognizes that it is the correct one. Each lock brand has a distinct keyway that allows it to be unlocked or locked with a specific type of key. Within a single brand, however, there are many different keyway shapes and sizes available. This provides a degree of security for different locks, since keys of the same brand can't be used to unlock the other's. In the majority of residential settings, the latch is operated by a lever that can be pushed or lifted in order to release the bolt. This is more comfortable than a knob that requires you to turn. However some commercial settings use knobs for added security. When the key is correctly installed, a spring-loaded set of pins move into place so that the plug can turn. The pins also align with grooves on the blade of the key, which allows them to recognize the correct key and blocking access. If the cylinder has been manipulated in a way that is not correct, or if a key is not a proper fit the pins will shift to the control line rather than the operating shear line and the lock will not be able to open. In this situation it is likely that the key has been re-keyed. This involves moving the pins up to the proper height so that the key rotates freely within the cylinder. This is typical when keys need to be transferred from one lock to another in a dormitory. It's not uncommon for individuals to change their locks as they move houses, or to grant access to a new roommate or employee without needing to change all locks to the same key. This is a reasonable option to improve security for a home and is often accomplished with only the key cylinder. Installation Changing a lock barrel on uPVC doors is a simple task that can be done at home. The first step is to locate the screw under the lock on the edge of the uPVC door. It will usually be noticeable because it is an entirely different color. Then, remove it using the help of a Phillips screwdriver. Next, take the new barrel and put it into the previous hole. Then, replace the knob with the barrel and push rod. It is essential to confirm the position of each component (the barrel, push rod and spring / lever housing) before you begin assembling. With the help of a screwdriver, you are able to easily remove the handle and knob to access the lock body. Once this is done, the cylinder can be rotated counterclockwise in order to loosen it. It is now possible to either remove the cylinder and get it “re-keyed” or leave it in the position it is in. Re-keying does not alter the pins in the cylinder. It will only move them into the proper location using the key that matches. The other option is to remove the cylinder and install a replacement. If you choose this option it is important to use the same size as the old cylinder, and ensure that the pins are placed correctly to allow your lock to work correctly. After you have installed the new cylinder, it's a good idea for you to lubricate it to make sure that everything runs smoothly. The process is a bit more difficult if you own mortise sets. This kind of lock is installed into a pocket (mortise), which is cut into the edge the door. It will require some careful measuring and maybe a few attempts to make the latch and bolt sections to align. Once they do then you'll have to take off the strike plate (which is fixed by screws that are located on the both sides of the frame of the door) and the latch bolt, which can be an arduous task if you do not have the proper tools.
