Front Door Lock Barrel Replacement

Front door barrel replacement for locks is a relatively easy DIY job that will save you the expense of calling out locksmiths. You can buy kits that include everything you need to complete the task.

You will need to purchase a new cylinder-lock barrel, a screwdriver set that is solid, a hammer or pliers, for extra grip and the lubricant.

Length

There are a myriad of lock barrel types to ensure your front door is as safe as is possible. When selecting a new lock type the length is essential to the security of your home. Cylinders that extend too far can snap, and those that are too short can prevent you from turning the key to unlock the door. Fortunately, there are several ways to determine the correct cylinder length, so you can purchase a replacement that will provide your door with maximum protection.

To determine the proper size of the cylinder, remove the old one from the door. Remove the screws that hold the lock cylinder. Once the cylinder has been removed, you can determine the distance from the center of the screw hole on the cylinder up to the edge of the backplate for the handle on the inside of the door. Include the thickness of the plate as well. You can also take a measurement of the length of the threaded shaft that is on the new cylinder to determine the size.

After determining the length of the cylinder you can then install it in your door. Start by using a drill to create a face bore hole in the door. This is where the handle or knob will be placed and should be a little larger than the diameter of the new cylinder. After that, you can attach the handle or knob to the handle you want to replace and ensure that it goes through the latch's spindle and operates smoothly when turned.

If you're replacing a deadbolt, you should also consider upgrading your strike plate. The strike plate is a piece of metal attached to the doorjamb which locks into the deadbolt once the key is pushed into. It's crucial to replace the strike plate with a high-security version that is more difficult to penetrate. Choose a strikeplate that has a reinforced metal construction to protect against kick attacks. Make sure to use screws that are at least 2.5-3 inches in length to ensure they are able to penetrate deep into the doorjamb.

Design

The lock cylinder is a component of the front door lock that you use to open or close the handle. It is made up of pins that move into place when you insert a key. When it comes to choosing the right lock cylinder you'll need to be aware of a few things. For instance, it's essential to measure the length of your current lock to ensure you purchase the correct size. It is also important to consider any furniture for doors, like handles or escutcheons.

Euro cylinder locks come in a variety of designs. Some are double cylinder locks that offer security from both sides of the door. They're often fitted to doors that require more security than standard ones and are also utilized in commercial buildings. Check that the lock you're considering is British Standards approved, and has the following requirements:

Anti-Snap: A burglar may attempt to snap a lock by applying pressure to the exterior of the door. To prevent this the lock must have a thin sacrificial line that's cut into the cylinder body.

Anti-Drill – Some burglars attempt to drill into the lock and break into a home. To stop this from happening the pins of a cylinder should be made of hardened metal.

Keyway

The keyway on locks is the shape of the interface between the cylinder and the key. The key has a set of ridges and grooves which run down the length of its "blade", and when inserted, these coincide with the cutouts in the pins of the cylinder. This is how the cylinder detects the correct key and allows it to turn.

Each brand of lock has a unique keyway that allows it to be locked or unlocked using a specific type of key. There are a variety of keyway sizes and shapes within a single brand. This ensures a certain level of security for locks since keys from the same brand cannot be used to open one other's.

In most homes, the latch is operated using an adjustable lever that can be pulled down or lifted to release the bolt. This is more comfortable 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 shifts into position to allow the plug to move. The pins align with grooves on the blade of the key and allow the lock to recognize the correct key. If the cylinder is manipulated incorrectly, or if the key is not a proper fit, the pins will shift to the control line rather than the operating shear line, and the lock will not be able to open.

In the case of this particular photo it's possible that the cylinder was re-keyed, a process where the existing pins are shifted upward to the proper height so that the key can freely rotate inside the cylinder. This is common when keys need to be transferred from one lock to another in a dormitory. It is not uncommon for people to have their locks changed as they move houses, or to allow access to new roommates or employees without having to change all the locks to the same key. This is a reasonable option to enhance security for a home and is usually done using just the key cylinder.

The first thing to do is locate the screw under the lock on the edge of the door made of uPVC. It will usually be noticeable because it is an entirely different color. Then, you can remove it using an Phillips screwdriver. Then, you can take the new barrel and place it into the last hole. Afterward, put the knob with the new barrel and push rod back in place. It is important to check the orientation of each part (the barrel, push rod and spring / lever housing) before you start reassembling.

You can then either take off the cylinder and be able to have it "re-keyed" or leave it in the position it is in. Re-keying won't change the pins of the cylinder. It will only shift them into the proper position with the key that matches.

upvc door locks replacement is to simply remove the cylinder and replace it with an entirely new one. If you decide to do this, it is crucial to choose the same size as the old cylinder, and ensure that the pins are placed properly to allow the lock to function properly. It is also a good idea to use lubricant on the new cylinder after installing it to ensure that everything is moving smoothly.

If you have a mortise lockset the procedure will be a bit more difficult. This type of lock is set inside pockets (mortise) cut into the side of the door, therefore it will require careful measurements and maybe a few attempts to get the latch and bolt sections to align. Once they do it, you'll need remove the strike plate (which is secured by screws that are located on the top and bottom of the frame of the door) and the latch bolt, which can be an arduous task if you do not have the proper tools.
