Rim Cylinder

How to change a rim cylinder lock?

Changing a rim cylinder lock is generally a simple process, and can be done with a few basic tools. Here are the general steps:

1. Remove the old cylinder: Use a screwdriver to remove any screws that are holding the cylinder in place. If the cylinder is stuck, you may need to use a pair of pliers or a wrench to loosen it. Once the cylinder is loose, pull it out of the door.

2. Measure the cylinder: Before purchasing a new cylinder, measure the length and diameter of the old cylinder. Make sure that the new cylinder is the same size as the old one.

3. Insert the new cylinder: Insert the new cylinder into the hole in the door. Be sure that it is inserted all the way and that it is aligned correctly. If necessary, adjust the orientation of the cylinder so that the keyway is facing in the correct direction.

4. Secure the new cylinder: Use a screwdriver to install any screws or bolts that came with the new cylinder. If the cylinder came with a backplate, install it now as well.

5. Test the new cylinder: Once the new cylinder is installed, test it by inserting the key and turning it. The locking mechanism should operate smoothly and the door should unlock and lock as expected.

It's important to note that rim cylinder locks may also have a backplate that is secured with screws, which will also need to be removed and replaced when changing the cylinder.

By following these steps, you should be able to change the rim cylinder lock on your door. If you are not comfortable doing this yourself, or if you encounter any problems during the process, it is always a good idea to contact a professional locksmith for assistance.

What is a rim cylinder? 

A rim cylinder is a type of lock cylinder that is mounted on the surface of a door or gate, rather than being installed within the door like a mortise lock cylinder. It is typically used in conjunction with a rim lock or rim latch, which is a surface-mounted lock that is attached to the inside of the door or gate.

A rim cylinder lock consists of a cylinder that contains the locking mechanism, a keyway for inserting the key, and a tailpiece that connects the cylinder to the lock mechanism. The cylinder is inserted into a hole on the surface of the door or gate and is secured in place with screws or bolts.

Rim cylinder locks are commonly used in residential and commercial applications, and can be found on doors, gates, and other types of access points. They are often used in situations where it is not possible or desirable to install a mortise lock cylinder, such as on doors with glass panels or thin metal doors.

One advantage of rim cylinder locks is that they are generally easier to install and replace than mortise locks, since they do not require a complex mortise cutout in the door. However, they may be less secure than mortise locks, since the cylinder is exposed on the surface of the door and may be vulnerable to tampering or attack.
