To determine the proper size of the cylinder, take out the old cylinder from the door. Remove the screws that hold the lock cylinder. Once the cylinder has been removed and you are able to 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 determine the length of the threaded shaft that is on the new cylinder to determine the size.
Install the cylinder inside your door after determining its length. Start by using a drill to create an entrance hole for the door. This is where the knob or handle will be placed and should be a little larger than the diameter of your new cylinder. Attach the interior knob or handle to the new handle. Make sure that it is able to fit into the spindle of the latch and turns smoothly.
When replacing a deadbolt, it is recommended that you must also replace your strike plate. The strike plate is the piece of metal that is attached to the doorjamb and locks into the bolt when forced in by a key. It's crucial to replace the strike plate with a high-security version that is harder to penetrate. Choose a strike plate with an enhanced metal design to stop kick attacks, and make sure the screws are at least 2.5-3 inches long to ensure they go deep into the doorjamb.
Design
The lock cylinder is the part of your front door lock that you use to open and close the handle. It has pins that move into position when you insert the key. When it comes time to select the correct lock cylinder, you'll need to know a few things. It is crucial, for instance to measure the length of the cylinder locks you currently have to ensure that you order the right size. You'll also need to take into consideration any door furniture, such as handles or escutcheons.

They are typically fitted to doors that require greater security than standard locks and are also used in commercial spaces. If you're in the market for an upgrade to your lock, make sure that it's British Standards approved and meets the following requirements:

Included in this are an appropriate screwdriver for the job as well as a hammer to provide extra grip, and pliers. It's also a good idea to have oil on hand to ensure the mechanism operates smoothly. Be aware that changing the lock on uPVC isn't easy. If you're not sure about the task you should call in a specialist or locksmith for help.
Keyway
The keyway on a lock is the shape of the connection between the cylinder and the key. The key is made up of a series of ridges and grooves which are affixed to its "blade", and when inserted, these coincide with the cutouts in the cylinder's pins. The cylinder is able to turn if it can confirm that the key is the right one.
Each lock brand has a distinct keyway that allows it to be locked or unlocked using a specific type of key. Within a single brand, there are different shapes and sizes that you can pick from. This gives a certain level of security for different locks, since keys from the same brand can't be used to open the locks of another.
In most residential settings the latch is operated by an adjustable lever that can be pulled or lifted in order to release the bolt. This is more ergonomic than the knob that needs to turn. Certain commercial settings still utilize knobs to provide security.
When the correct key is inserted, a spring-loaded set of pins move into place to allow the plug to move. The pins align with grooves on the blade of the key and allow the lock to recognize the right key. If the key or cylinder is not correctly inserted, the pins will move towards the control shear rather than the operating line. The lock will not open.
In this particular photo it's likely that the cylinder was reset-keyed, which is when the pins in the cylinder are moved up to the correct height to allow the key to freely move within the cylinder. This is a common practice in dormitories where the key for a single person could have to be moved between dozens of locks. Many people need their locks changed when they move houses or wish to give access to a new employee or roommate without the need to change all the locks to the same key. This is an affordable option to improve security for a home and is often done with just the key cylinder.
Installation
It is easy to change the barrels of locks in the uPVC door. The first step is to find the screw under the lock at the edge of the door, it usually stands out from the other screws due to its different color. Then, remove it using a Phillips screwdriver. Then, you can take the new barrel and put it into the previous hole. Then, place the knob with the new barrel and push rod back into position. When 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 have been removed you can easily gain access to the lock's body by loosening the set screw that holds it in place using an screwdriver. The cylinder can be unscrewed by rotating it counterclockwise. At this point, you are able to either keep the cylinder in place and get your locks "re-keyed" or take it out of it. Re-keying won't alter the pins inside the cylinder. It will simply shift them into position with the key that matches it.
Another option is to simply remove the cylinder and install another. If you decide to go this route it is crucial to use the same size cylinder as your old one and that the pins are positioned correctly. This will ensure that your lock works correctly. It is also a good idea to use lubricant on the new cylinder after it has been installed to ensure that everything is moving smoothly.
The process is a bit more complicated if you're using a mortise set. This kind of lock is inserted inside the pocket (mortise), which is cut into the side of the door. It will require careful measurements and possibly a few attempts to get the latch and the bolt sections to coincide. Once they do then you'll have to take off the strike plate (which is secured by screws that are located on the both sides of the door frame) and the latch bolt, which can be difficult if you don't have the right tools.
