Make sure to include the thickness of the plate, as well. You can also measure the length of the threaded shaft that is on the new cylinder to determine its size. Install the cylinder in your door after determining its length. Start by drilling a hole in the door. bletchley double glazed door lock replacement is the place where the handle or knob will be placed and it should be slightly larger 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 is able to turn smoothly when it is turned. If you are replacing a deadbolt, you must also consider upgrading your strike plate. The strike plate is the piece of metal that mounts to the doorjamb and locks into the bolt once it's forced in by a key. It's crucial to replace the strike plate with one that is harder to penetrate. Find a strikeplate with a reinforced metal structure to protect against kick attacks. Use screws that are at least 2.5-3 inches long to ensure they are able to penetrate deep into the doorjamb. Design The lock cylinder is the component of your front door lock that you use to open and close the handle. It has pins that move into place when you insert keys. When it comes time to select the right lock cylinder you'll need to know a few things. For instance, it's crucial to determine the length of your existing lock to ensure you order the right size.

They are typically fitted to doors that require more security than standard locks, and they're also used in commercial buildings. Make sure the lock you are considering is British Standards approved, and has the following requirements: Anti-Snap: A burglar may attempt to snap a cylinder by applying pressure to the exterior of the door. To stop this from happening, a thin strip of sacrificial material is cut into the cylinder. Anti-Drill: Some burglars are able to penetrate the lock in order to gain entry into a home. To prevent this the pins of a cylinder should be made of hardened metal. If you're looking to purchase an entirely new cylinder, you must also think about whether it's anti-drill. This will prevent a burglar from drilling into the plug using a power drill and breaking it up. Once you've chosen a new cylinder lock you'll need to gather the necessary components to put it in.

Before you begin, remember that changing the barrel of a lock on a uPVC door isn't easy. If you're not confident about doing the work yourself, you should seek out a locksmith or expert for assistance. Keyway The keyway on a lock is the shape of the cylinder's interface and the key. The key has a set of grooves and ridges that are affixed to its “blade” and, when inserted, these coincide with the cutouts in the cylinder's pins. This is how the cylinder detects the correct key, and allows it to turn. Each lock brand comes with a different keyway which allows it to be locked or unlocked with the use of a particular key. There are various keyways sizes and shapes within the same brand. This gives a certain level of security between locks as keys from the same brand can't be used to open each other's. In the majority of residential settings, the latch is operated by a lever that can be lifted or pushed to let loose the bolt. This is more ergonomic than the knob that needs to turn. Certain commercial settings still utilize knobs for security. When the key is correctly inserted, a spring-loaded set of pins shifts into position so that the plug can move. The pins also align with grooves in the blade of the key, identifying the correct key and blocking access. If the cylinder has been manipulated improperly, or if the key is not a proper fit, the pins will shift to the control line instead of the operating shear line, and the lock will be unable to open. In this case it is likely the key has been re-keyed. This involves moving the pins up to the correct height so that the key can rotate freely within the cylinder. This is common when a key needs to be moved from one lock to the next in a dormitory. It is common for people to require their locks to be rekeyed whenever they move or want to allow access to a new employee or roommate without the need to change all of the locks to the same key. This is an affordable option to increase security for a home and is usually done with just the key cylinder. Installation It is simple to change the barrels of locks in the door made of uPVC. The first thing to do is to locate the screw under the lock at the edge of the uPVC door. It will usually be visible because it has an unusual colour. Then remove it using an Phillips screwdriver. Then, you can insert the new barrel into the previous slot. Then, place the knob on the new barrel and push rod back in place. It is important to check the direction of each piece (the barrel, push rod and lever housing / spring) before you start reassembling. With an screwdriver, you can easily remove the handle and knob to access the lock body. After this is done, the cylinder can be rotated counterclockwise to unscrew it. You can then either take off the cylinder and get it “re-keyed” or keep it in place. A re-key will not change the pins in the cylinder. It will simply move them to the key that matches it. Another option is to remove the cylinder, and replace it with a new. If you opt for this option, it is important to use the same size cylinder as the one you had previously and that the pins are placed in the correct position. This will ensure that the lock functions correctly. It is also an excellent idea to use lubricant on the new cylinder after installing it to ensure that everything moves smoothly. If you are using a mortise lockset the process will be slightly more complicated. This kind of lock is installed inside a pocket (mortise), which is cut into the edges of the door. It will require careful measurements and possibly a few tries to get the latch and bolt sections to be aligned. Once the bolt and latch sections are aligned then you can take off the strike plate, which is secured on the sides and the bottom of your door frame using screws.
