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 attached to the new cylinder. After determining the length of the cylinder, you can install it inside your door. Start by drilling a hole through the door. This is where the handle or knob will go and should be slightly larger than the diameter of the new cylinder. Attach the knob on the inside or handle to the new handle. Make sure it is able to fit through the spindle of the latch and rotates smoothly. When replacing a deadbolt you must also replace the strike plate. The strike plate is the piece of steel that mounts to the doorjamb and locks into the bolt when forced in by a key. It's crucial to replace this plate with a more secure version that is harder to penetrate. Find replacement upvc door lock with a reinforced metal construction to withstand kick attacks. Make sure to use screws that are 2.5-3 inches in length to ensure they are able to penetrate deep into the door jamb. Design The lock cylinder is part of the front door lock that you use to open or close the handle. It has pins that slide into position when you insert the key. When it comes time to select the correct cylinder for your lock, you'll need to know a few things. For instance, it's essential to measure the length of your current lock cylinder so that you can select the appropriate size. You'll also need to consider any furniture for doors, like handles or escutcheons. Euro Cylinder locks come in a variety of styles. Some of these double cylinder locks provide security on both sides of the doors. They are typically fitted to doors that require greater security than standard locks and are also used in some commercial premises. If you're looking to purchase a new lock, check that it's British Standards approved and meets the following criteria: Anti-Snap – A burglar can try to snap a cylinder by applying pressure to the exterior of the door. To prevent this, the lock should have a thin sacrificial line that's cut into the cylinder body. Anti-Drill: Some burglars attempt to cut holes in the lock in order to gain entry into a home. To avoid this the pins on a cylinder must be made from hardened metal. If you're in the market for a new cylinder, then you should also consider whether it's anti-drill. This will stop a burglar from tearing the plug off by drilling into it using a power tool. Once you've selected the cylinder lock that you want to install, you will have to gather all the components you'll need to put it in place. Included in this are an appropriate screwdriver for the task and a hammer for additional grip and pliers. It is also recommended to have fluid to ensure that the mechanism runs smoothly. Before you begin, keep in mind that changing the barrel of a lock on a uPVC door can be difficult. If you're not confident about the task it is recommended to contact a professional or locksmith for assistance. Keyway Keyway is the shape that the interface between cylinder pins and the key has. The key's “blade” has a series grooves and ridges that run along its length. When inserted into the lock, they align with the pins of the cylinder. The cylinder is able to turn if it can confirm that the key is the correct one. Each brand of lock has a distinct keyway that allows it be locked or unlocked using specific keys. There are various keyways sizes and shapes within a single brand. This ensures a certain level of security for locks since keys of the same brand cannot be used to open the other's. In most homes, the latch is operated by an adjustable lever that can be lifted or pushed to let loose the bolt. This is more ergonomic than the knob that needs to turn. Some commercial settings still use knobs for security. When the correct key is put in, a set of spring-loaded of pins move into place to allow the plug to rotate. 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 properly inserted, the pins will move to the control shear, rather than the operating line. The lock will not open. In the case of this particular photograph it's possible that the cylinder was reset-keyed, which is when the pins in the cylinder are moved up to the correct height so that the key can rotate freely inside the cylinder. This is typical when keys need to be moved from one lock to another in a dormitory. It is not uncommon for people to change their locks when they move houses or if they want to give access to a new roommate or employee without having to change all the locks to the same key. This is a cost-effective way to improve the security of your home. It can be accomplished by changing only the key for the cylinder. Installation Changing a lock barrel on doors made of uPVC is a simple task that can be accomplished at home. The first step is to locate the screw under the lock at the edge of the door. It is usually distinct from the rest of the screws as it has a different color. Then, you can remove it using the help of a Phillips screwdriver. Then, put the new barrel into the previous slot. Afterward, put the knob that was previously used with the new barrel and push rod back into position. It is essential to confirm the position of each component (the barrel, push rod and the lever housing and spring) before you start reassembling. Once the handle and knob are removed you can easily access the lock body by loosening the set screw that holds it in place with the help of a screwdriver. Once this is done the cylinder can be rotated counterclockwise in order to loosen it. You can now either remove the cylinder and have it “re-keyed” or leave it in the position it is in. Re-keying will not change the pins in the cylinder. It will only move them into the proper position using the key that matches. The other option is to take the cylinder off and install a replacement. If you opt for this option, it is crucial to choose the same size as your old cylinder and make sure that the pins are placed correctly to allow your lock to function correctly. It is also recommended to apply oil on the new cylinder following installation to ensure that everything operates smoothly. The process can be a little more complicated if you're using a mortise set. This type of lock installs inside a pocket (mortise) cut into the edge of the door. Therefore, it will require careful measurement and perhaps a few tries to get the bolt and latch sections to align. When they do it, you'll need remove the strike plate (which is held in place by screws at the top and bottom of the door frame) and the latch bolt, which can be a difficult task without proper tools.
