To determine the proper size of the cylinder, remove the old cylinder from the door. Make use of a screwdriver to take out the screws that keep the lock cylinder. Once the cylinder has been removed, you can determine the distance between the center of the screw hole in the cylinder to the edge of the handle backplate on the inside of the door. Include upvc door locks replacement of the plate, too. You can also determine the length of the threaded shaft on the new cylinder to determine its size. After determining the length of the cylinder you can then place it in your door. Begin by using a drilling tool to create a face bore hole in the door. This is where the knob or handle will go and should be slightly larger than the diameter of your new cylinder. Then, attach the handle or knob to the new handle and ensure that it is able to pass through the spindle of the latch, and is able to turn smoothly when it is turned. If you're replacing a deadbolt you should also consider upgrading your strike plate. The strike plate is the piece of steel that attaches to the doorjamb and locks into the bolt once it's pushed in by a key. This plate should be replaced with a safer version. Find strike plates with an enhanced metal design to resist kick attacks, and make sure that the screws are at least 2.5-3 inches long to ensure that they get deep into the door jamb. Design The lock cylinder is a part of the front door lock you can use to open or close the handle. It has pins that slide into place when you insert the key. It is important to be aware of a few points when selecting the right lock cylinder. For instance, it's crucial to determine the length of your existing lock cylinder so that you can purchase the correct size. Also, you should consider any furniture for doors, like handles or escutcheons. Euro Cylinder locks are commonly used in homes, and they're available in a variety of designs. Some of these double cylinder locks are secure on both sides of doors. They are commonly employed on doors that require more security than regular locks, and also in some commercial buildings. If you're in the market for a new lock, ensure that it's British Standards approved and meets the following requirements: Anti-Snap: An intruder could attempt to break the cylinder by applying force to the door's outside. To avoid this the lock must have a thin sacrificial line that's cut into the body of the cylinder. Anti-Drill – Some burglars try to drill into the lock and break into homes. To prevent this from happening, a cylinder should have pins made of steel that has been hardened. If you're looking for a new cylinder, you should consider whether it's anti-drill. This will stop a burglar from ripping the plug out by drilling it with a power tool. Once you've selected the cylinder lock that you want to install, you will have to gather all the necessary materials to put it in place. Included in this is an appropriate screwdriver for the job and a hammer for additional grip and pliers. You should also have some lubricant to ensure that the mechanism runs smoothly. Be aware that changing locks on a uPVC can be difficult. If you're not confident about the job, it is best to seek out a specialist or locksmith for help. Keyway Keyway is the shape that the interface between the cylinder pins and the key takes. The key's “blade” is made up of a series of grooves and ridges along its length. When the key is inserted, they align with the pins of the cylinder. The cylinder can only rotate if it recognizes that the key is the right one. Every lock model has a different keyway, which allows it to be locked or unlocked by using the use of a specific key. There are various keyways sizes and shapes within a single brand. This provides a degree of security for different locks, since keys from the same brand are not able to unlock each other's. In most residential settings the latch is operated by the lever, which 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 utilize knobs to provide additional security. When the correct key has been inserted, spring-loaded pins shift into position allowing the plug to be rotated. The pins are aligned with grooves on the blade of the key which allows the lock to recognize the correct key. If the cylinder or key is not properly inserted the pins will be moved to the control shear rather than the operating line. The lock won't open. In this particular photograph it's possible that the cylinder was re-keyed, a process where the pins that are in place are moved up to the correct height so that the key can freely move within the cylinder. This is a common practice in situations of shared housing where the key for one person might need to be moved between multiple locks. It's not uncommon for individuals to have their locks re-keyed when they move houses or if they want to grant access to new roommates or employees without having to change all locks to the same key. This is a cost-effective method to improve security for a home. It can be done by simply changing the key for the cylinder. Installation Changing a lock barrel on doors made of uPVC is a straightforward task that can be completed at home. The first step is to find the screw underneath the lock on the outside of the door. It is usually distinct from the rest of the screws because it is a different color. Then, remove it with an Phillips screwdriver. Next, take the new barrel and put it into the hole you removed. Then replace the knob with the push rod and the barrel. Before reassembling, it is essential to make sure that each component is aligned correctly (the rod and the barrel as well as the spring/lever housing). Once the knob and handle are removed you can easily gain access to the lock's body by loosening the set screw that holds it in place using a screwdriver. Once you have done this the cylinder can be rotated counterclockwise in order to loosen it. At this point, you can either keep the cylinder in place and have your locks “re-keyed”, or remove it. Re-keying will not alter the pins within the cylinder, it will simply shift them into position with the key that matches it. Another option is to remove the cylinder, and install a replacement. If you decide to do this, it is important to use the same size as your old cylinder and ensure that the pins are placed correctly in order for your lock to function correctly. After you have installed the new cylinder, it's an ideal idea to lubricate it to make sure that everything is moving smoothly. If you are using a mortise lockset the process is slightly more complicated. This type of lock is set inside the pocket (mortise) that is cut into the edge the door. It will require some careful measurements and possibly several attempts to get the latch and the bolt sections to be aligned. When they do, you will need remove the strike plate (which is fixed by screws that are located on the both sides of the door frame) and the latch bolt, which is difficult if you don't have the right tools.
