Length
There are a variety of lock barrel types to ensure that your front door is as safe as it can be.

Cylinders that protrude too far are more likely to snap, whereas those which are too small may hinder you from turning your key to unlock the doors. There are a variety of methods to determine the right cylinder length, so you can buy a replacement that will offer your door the best protection.
The first step in determining the correct cylinder length is to remove the existing one from the door. Take off the screws that are holding the lock cylinder.

Include the thickness of the plate, too. 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 place it inside your door. Start by drilling a hole through the door. This is the hole in which the handle will be placed. It should be slightly bigger than the diameter of the new cylinder. Attach the knob on the inside or handle to the handle you are replacing. Make sure that it is able to fit into the spindle of the latch and rotates smoothly.
When replacing a deadbolt you should also upgrade the strike plate. The strike plate is the piece of metal that mounts to the doorjamb and locks into the bolt once it's driven in by a lock. The plate should be replaced with a safer version. Choose a strike plate with a reinforced design that can protect against kick attacks. Also, use screws that are at least 2.5-3 inches long to ensure they go deep into the door jamb.
Design

When it comes to selecting the correct cylinder for your lock, you'll need to know a few things.

Make sure the lock you're viewing is British Standards approved, and is in compliance with these 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 body of the cylinder.
Anti-Drill - Some burglars attempt to drill holes into locks and then break into homes. To prevent this the pins of a cylinder should be made of hardened metal.

Keyway
Keyway is the shape that the interface between cylinder pins and the key takes. The key has a series of grooves and ridges that are affixed to its "blade" and, when it is inserted, they align with the cutouts on the cylinder's pins. The cylinder will only move if it is sure that the key is the correct one.
Each brand of lock has a distinct keyway that permits it to be locked or unlocked with specific keys. Within a single brand however, there are many different keyway styles and sizes to choose from. This allows for a level of security for different locks, as keys of the same brand cannot be used to open the locks of another.
In most homes the latch is operated by a lever, which can be pushed down or lifted to let the bolt go. more info is typically more comfortable than a knob which requires you to turn it. Some commercial settings still use knobs to provide security.
When the correct key is put in, a set of spring-loaded of pins move into place 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 is manipulated in a way that is not correct, or if a 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 this particular image it's possible that the cylinder has been changed into a new key, which is a process in which the existing pins are shifted upwards to the right height to allow the key to rotate freely inside the cylinder. This is typically the case in dormitory situations where the key for one person may need to be moved between several locks. Many people require their locks to be rekeyed whenever they move or want to allow access to a new employee or roommate without having to change the locks all to the same key. This is a cost-effective way to increase the security of the home. It can be done by simply changing the key for the cylinder.
Installation
The process of changing the barrels on locks on doors made of uPVC is a simple job that can be accomplished at home. The first thing to do is to locate the screw under the lock on the edge of the door made of uPVC. It will usually stand out because it has an unusual colour. Then, you can remove it using an Phillips screwdriver. Then, put the new barrel into the last slot. Then replace the knob with the push rod and the barrel. Before reassembling, it's essential to make sure that each component is aligned correctly (the rod and the barrel as well as the spring/lever housing).
After the handle and knob are removed you can easily access the lock body by loosening the set screw that holds it in place using the help of a screwdriver. The cylinder is then unscrewed by rotating it counterclockwise. At this point, you can either leave the cylinder in place and have your locks "re-keyed" or take it off it. A re-key will not change the pins within the cylinder. It will simply move them into position with the key that matches it.
The other option is to remove the cylinder, and then install a new. If you decide to do this, it is crucial to choose the same size as the old cylinder, and ensure that the pins are positioned correctly in order for your lock to work correctly. It is also an excellent idea to use oil on the new cylinder following installation to ensure that everything moves smoothly.
If you have a mortise lockset, the process is slightly more difficult. This kind of lock is installed inside pockets (mortise) cut into the side of the door. Therefore, it will require careful measurement and possibly a few tries to get the latch and bolt sections to line up. Once they do it, you'll need to remove the strike plate (which is secured by screws at the top and bottom of the frame of the door) and the latch bolt, which is an arduous task if you do not have the proper tools.
