Include the thickness of the plate too. You can also determine the size of the cylinder by measuring the length of the threaded spindle on the new cylinder. Install the cylinder in your door after determining its length. Begin by drilling a hole in the door. This is where the knob or handle will go and should be a little larger than the diameter of the new cylinder. Attach the knob on the inside or handle to the new handle.

Keyway The keyway on a lock is the shape of the interface between the cylinder and the key. The key's “blade” is made up of a series of grooves and ridges along its length. When the key is inserted into the lock, they align with the pins of the cylinder. This is how the cylinder recognizes the correct key, and allows it to rotate. Every lock model comes with a different keyway that allows it to be locked or unlocked with the use of a specific key. There are various keyways sizes and shapes within the same brand. This allows for a level of security between different locks since keys of the same brand cannot be used to open the locks of another. In most homes, the latch is operated using a lever, which can be pushed downwards or lifted to let the bolt go. This is often more ergonomic than a knob which requires you to turn it. However, some commercial settings still utilize knobs to provide additional security. Once the key that is correct has been inserted, the spring-loaded pins are shifted into a position that allows the plug to rotate. The pins also align with grooves on the blade of the key, identifying the correct key, but denying access. If the cylinder is operated incorrectly, 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 the case of this particular photo it's likely that the cylinder was previously reset-keyed, which is when the existing pins are shifted upward to the proper height to allow the key to freely move within the cylinder. This is common in situations of shared housing where the key for one person might need to be moved between dozens of locks. It's not uncommon for individuals to change their locks when they move homes, or to allow access to new roommates or employees without needing to change all locks to the same key. This is a cost-effective way to improve security for the home. It can be done by simply changing the key to the cylinder.

Then, you can remove it using the help of a Phillips screwdriver. Then, grab the new barrel and insert it into the last hole. Afterward, put the knob on the new barrel and push rod back into place. It is important to check the direction of each piece (the barrel, push rod and spring / lever housing) before you start reassembling. After the handle and knob have been removed, you can gain access to the lock's body by loosening the set screw that holds it in place using the help of a screwdriver. Once you have done this the cylinder is turned counterclockwise to remove it. At this point, you can either leave the cylinder in place and have your locks “re-keyed” or take it out of it. Re-keying won't change the pins in the cylinder. It will simply shift them into the proper position with the key that matches. The other option is to take the cylinder off and replace it with a new. If www.repairmywindowsanddoors.co.uk decide to do this, it is essential to use the same size as the old cylinder and make sure that the pins are positioned correctly in order for your lock to work correctly.
