Changing the cylinder on a lock is a relatively simple task that can be completed in a few minutes. However, it is important to note that this task should only be attempted by those who are comfortable working with tools and have a basic understanding of how locks work. If you are not comfortable performing this task, it is best to contact a professional locksmith.
The first step is to remove the old cylinder. To do this, you will need to insert a key into the lock and turn it to the unlock position. Once the lock is unlocked, you can use a screwdriver to remove the screws that are holding the cylinder in place. Once the screws are removed, you can pull the cylinder out of the lock. If you are having difficulty removing the cylinder, you can try using a pair of pliers to gently pull it out.
Once the old cylinder is removed, you can insert the new cylinder. To do this, simply align the cylinder with the lock and push it into place. Once the cylinder is in place, you can use a screwdriver to tighten the screws that are holding it in place. Once the screws are tightened, you can insert a key into the lock and turn it to the lock position. If the lock works properly, you have successfully changed the cylinder.
Identifying the Lock Cylinder
Identifying the lock cylinder is the initial and crucial step in changing a lock cylinder. Here’s a detailed guide to help you locate and identify the lock cylinder:
Visual Inspection
Examine the lock carefully. The cylinder is typically a cylindrical or oval-shaped component located in the center of the lock. It may have a keyhole or a thumb turn on its surface. Depending on the lock type, the cylinder may be visible from the exterior or may require removing the lock from the door for inspection.
Removal of Lock Components
In some cases, it may be necessary to remove certain lock components to access the cylinder. This could involve removing the faceplate, strike plate, or handle from the lock. Note that the specific steps for removing these components may vary depending on the lock type.
Identification by Key
Insert the key into the lock and turn it slightly. Observe the movement of the key within the cylinder. If the key moves smoothly and engages with the tumblers, it indicates that the cylinder is functional. A key that does not fit or turns with difficulty suggests a faulty or incompatible cylinder. Additionally, the keyhole itself can provide clues about the cylinder type. For instance, locks with narrow keyholes are likely to have narrow-profile cylinders, while locks with larger keyholes may have standard or large-format cylinders.
| Type of Keyhole | Possible Cylinder Type |
|---|---|
| Narrow | Narrow-profile cylinder |
| Standard | Standard cylinder |
| Large | Large-format cylinder |

Removing the Lock Cylinder
Once you have the lock removed from the door, you need to remove the lock cylinder. The steps for removing the lock cylinder will vary depending on the type of lock you have. Here are the general steps for removing a lock cylinder:
- Remove the screws that are holding the lock cylinder in place.
- Pull the lock cylinder out of the lock body.
- Insert the key into the lock cylinder and turn it to the unlock position.

Inserting the New Cylinder
Now that you have the lock cylinder removed, it’s time to insert the new one. The process is similar to removing the old cylinder, but in reverse. First, insert the new cylinder into the lock body. Make sure that the keyway is aligned with the keyhole. Then, turn the cylinder clockwise until it is fully seated. Once the cylinder is seated, you can insert the set screw. The set screw will help to keep the cylinder in place.
Once the set screw is tightened, you can insert the key and test the lock. If the lock works properly, you have successfully replaced the cylinder.
Things to Keep in Mind When Inserting the New Cylinder
Here are a few things to keep in mind when inserting the new cylinder:
– Make sure that the keyway is aligned with the keyhole. If the keyway is not aligned, the key will not be able to enter the lock.
– Turn the cylinder clockwise until it is fully seated. If the cylinder is not fully seated, it will not be able to function properly.
– Tighten the set screw. The set screw will help to keep the cylinder in place.
– Insert the key and test the lock. If the lock works properly, you have successfully replaced the cylinder.
Additional Tips
Here are a few additional tips that may be helpful when inserting the new cylinder:
– Use a flashlight to help you see inside the lock.
– If you are having difficulty inserting the cylinder, try using a pair of pliers.
– Be careful not to overtighten the set screw.
Tightening the Screws
Once the new cylinder is in place, it’s time to tighten the screws. These screws are located on either side of the cylinder and help to secure it in place. Use a screwdriver to tighten the screws until they are snug. Be careful not to overtighten the screws, as this can damage the cylinder.
In general, you’ll want to use a screwdriver that is the correct size for the screws. If the screwdriver is too small, it will be difficult to get a good grip on the screws and you may end up stripping them. If the screwdriver is too large, you may damage the screws or the cylinder.
To avoid damaging the screws or the cylinder, it’s important to use a screwdriver that is the correct size and to tighten the screws until they are snug. Overtightening the screws can damage the cylinder and make it difficult to operate the lock.
Here are some additional tips for tightening the screws:
