Front Door Lock Barrel Replacement Front door barrel replacement for locks is a relatively easy DIY task that can save you the cost of calling out locksmiths. You can buy kits that include all the tools you need. You'll require a brand new cylinder lock barrel and a reliable screwdriver set as well as pliers or hammers for extra grip, and oil lubricant. Length There are a variety of locks barrels to pick from that will ensure your front door is secure. But, when selecting the right type of lock barrel, the length of the cylinder could be critical to the security of your home. Cylinders that extend too far are prone to snapping and those that are too small can prevent you from turning the key to unlock the door. There are a variety of ways to determine the proper cylinder length, so you can buy a replacement that will provide your door with the maximum security. The first step in determining the correct length of cylinder is to remove the existing one from the door. Remove the screws holding the lock cylinder. After the cylinder has been removed it is possible to measure from the screw hole in the middle of the cylinder to the edge of the handle plate that is on the inside of the door. Include the thickness of the plate as well. You can also determine the cylinder size by measuring the length of the threaded spindle attached to the new cylinder. After determining the length of the cylinder, you can then place it inside your door. Begin by using a drilling tool to create an entrance hole for the door. This is where the knob or handle will be placed, and it should be slightly larger than the diameter of your new cylinder. Attach try here on the inside or handle to the handle you are replacing. Make sure it fits through the spindle of the latch and is turning smoothly. If you're replacing a deadbolt you should also think about upgrading your strike plate. The strike plate is a piece of metal mounted to the doorjamb which locks into the deadbolt when the key is pushed into. This plate should be replaced with a safer version. Choose a strikeplate that has a reinforced metal construction to resist kick attacks. Use screws that are at minimum 2.5-3 inches in length to ensure they are able to penetrate deep into the doorjamb. Design The lock cylinder is a part of the front door lock that you can use to open or close the handle. It has pins that move into place when you insert the key. When it comes time to select the right lock cylinder you'll need to know some things. For instance, it's essential to determine the length of your current cylinder lock so you can select the appropriate size. You will also need to take into consideration any door furniture, such as handles and escutcheons. Euro cylinder locks come in a variety of styles. Some are double cylinder locks that provide security from both sides of the door. They are commonly used on doors that require more security than standard locks, and in commercial buildings with a few. Make sure that the lock you are looking at is British Standards approved, and has the following requirements: Anti-Snap: A burglar could try to snap the cylinder by applying pressure to the outside of the doors. To stop this from happening, an sacrificial strip of thinness is cut into the cylinder. Anti-Drill: Some burglars are able to cut holes in the lock to gain entry into homes. To guard against this, a cylinder must have pins that are made of steel that has been hardened. If you're looking for a new cylinder, you should also consider whether it's anti-drill. This will prevent thieves from drilling into the plug with an electric drill and then breaking it apart. If you've decided to purchase the right cylinder lock, you'll need to gather the necessary components to put it in. This includes a screwdriver appropriate for the job, as well as an hammer and pliers to provide additional grip. It's also a good idea to have fluid to ensure that the mechanism is working smoothly. Before you begin, keep in mind that changing the barrel of a lock on a uPVC door isn't easy. If you're not confident about the job you should contact a professional or locksmith to assist you. Keyway Keyway is the shape that the interface between pins on the cylinder and the key has. The key's "blade" has a series grooves and ridges running down its length. When the key is inserted it, they align with pins of the cylinder. This is how the cylinder detects the correct key and allows it to rotate. Each lock brand has a distinct keyway that allows it be locked or unlocked using specific keys. There are a variety of keyway sizes and shapes within a single brand. This allows for a level of security for different locks, as keys of the same brand can't be used to unlock the other's. In most homes, the latch is operated by a lever that can be pulled or lifted in order to release the bolt. This is usually more comfortable than turning a knob which requires you to turn it. However, some commercial settings still use knobs for added security. When the key is properly put in, a set of spring-loaded of pins shift into position so that the plug can move. The pins also align with grooves in the blade of the key, identifying the correct key, but blocking access. If the cylinder or key is not inserted correctly the pins will shift 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 raising the pins to the correct height so that the key rotates freely within the cylinder. This is a common procedure when a key has to be transferred from one lock to another in the dormitory. Many people require their locks to be rekeyed whenever they move house or want to give 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 enhance security for a home and can often be accomplished with only the key cylinder. Installation Removing a barrel lock on doors made of uPVC is a straightforward task that can be accomplished at home. The first step is find the screw underneath the lock on the edge of the door made of uPVC. It will usually be visible because it has a different colour. Remove it with the Phillips screwdriver. Then, grab the new barrel and insert it into the previous hole. After that, you can put the knob that was previously used with the new barrel and push rod back in place. Before reassembling, it's essential to make sure that all parts are positioned correctly (the barrel and push rod as well as the spring/lever housing). With the help of a screwdriver, you are able to easily remove the knob and handle to access the lock body. The cylinder can be unscrewed by rotating it counterclockwise. It is now possible to either remove the cylinder and have it "re-keyed" or keep it in place. Re-keying will not change the pins in the cylinder. It will only shift them into the correct position using the key that matches. The other alternative is to simply take off the cylinder and then install an entirely new one. If you opt for this option it is essential to make use of the same cylinder that you used previously and that the pins are positioned correctly. This will ensure that your lock works correctly. After installing the new cylinder, it's an ideal idea to lubricate it to ensure that everything moves smoothly. If you are using a mortise lockset the process will be slightly more complicated. This type of lock is set into pockets (mortise) cut into the side of the door, so it will require careful measurement and maybe a few attempts to get the latch and bolt sections to align. When the latch and bolt sections are aligned, you can remove the strike plate that is held in place on the sides and the bottom of your door frame with screws.
