Make sure to include the thickness of the plate as well. You can also determine the size of the cylinder by measuring the length of the threaded spindle that is attached to the new cylinder. After determining the length of the cylinder you can then place it inside your door. Start by using a drill to create an entrance hole for the door. This is where the handle or knob will be placed and should be a little larger than the diameter of the cylinder you've created. Then, attach the handle or knob to the handle you want to replace and make sure it is able to pass through the latch's spindle and operates smoothly when turned. If you're replacing a deadbolt you must also consider upgrading your strike plate. The strike plate is the metal piece that mounts to the doorjamb and locks into the bolt when forced in by a key. The plate should be replaced with a safer version. Find a strike plate with a reinforced metal design to resist kick attacks, and use screws that are at least 2.5-3 inches long to ensure that they get deep into the door jamb. Design The lock cylinder is component of the front door lock you utilize to open or close the handle. It is equipped with pins that move into place when you insert the key.

To prevent this, a cylinder's pins should be made from hardened metal. If you are searching for a new cylinder, you should also check if it is anti-drill.

If you're unsure about doing the work yourself, you should seek out a locksmith or expert for assistance. Keyway The keyway is the form that the interface between the cylinder pins and the key takes. The key is made up of a series of grooves and ridges that extend along the length of its “blade” and, when it is inserted, they align with the cutouts in the pins of the cylinder. The cylinder can only move if it is sure that it is the correct one. Each brand of lock 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 the same brand. This provides a degree of security to different locks, as keys from the same brand cannot be used to unlock each other's. In most homes, the latch is operated by the lever, which can be pulled or lifted to open the bolt. This is more ergonomic than a knob that requires you to turn. Certain commercial settings still employ knobs to add security. When the key is properly inserted, a spring-loaded set of pins shift into position to allow the plug to move. The pins also align with grooves on the blade of the key, which allows them to recognize the correct key and denying access. If the cylinder or key is not correctly inserted the pins will be moved towards the control shear rather than the operating line. The lock won't open. In this situation it is likely that the key has been re-keyed. This involves moving the pins up to the right height so that the key rotates freely within the cylinder. This is common in dormitory situations where the key for one person may require a move between several locks. It's not uncommon for individuals to have their locks re-keyed when they move houses or when they wish to grant access to new roommates or employees without needing to change all locks to the same key. This is a cost-effective approach to increase the security of the home. It can be accomplished by changing only the key to the cylinder. Installation It is easy to change the barrel of a lock in the uPVC door. The first thing to do is locate the screw underneath the lock on the edge of the uPVC door. It is likely to be visible because it has an unusual colour. Then, remove it with an Phillips screwdriver. Then, you can take the new barrel and place it into the hole you removed. Then replace the knob with the push rod and barrel. Before reassembling, it is essential to make sure that each part is oriented correctly (the barrel and push rod as well as the spring/lever housing). Once the handle and knob have been removed you can easily access the lock body by loosening the screws that hold it in place using an screwdriver. After this is done the cylinder is turned counterclockwise to remove it. At this point, you are able to keep the cylinder in place, and have your locks “re-keyed” or take it out of it. Re-keying will not alter the pins within the cylinder, but will simply shift them into position with the key that matches it. Another option is to remove the cylinder, and then install a new. If you decide to do this, it is essential to use the same size as your previous cylinder and make sure that the pins are positioned correctly in order for your lock to work correctly. After installing the new cylinder, it's an ideal idea to apply lubrication to it to ensure that everything runs smoothly. The process can be a little more complicated if you're using a mortise set. This type of lock is set into pockets (mortise) that is cut into the edges of the door. It will require careful measurement and perhaps a few attempts to get the latch and bolt sections to coincide. Once the latch and bolt sections are aligned and you are able to remove the strike plate that is secured on the sides and the bottom of your door frame by screws.
