Mortise Cylinder

How to remove mortise cylinder without key?

Removing a mortise cylinder without a key can be a bit tricky, but it is possible. Here are a few methods that may work:

1. Use a pair of pliers: If the cylinder has a small knob on the outside, you may be able to use a pair of pliers to turn it. Grip the knob firmly with the pliers and turn it in the direction that would unlock the door. With a bit of luck, the cylinder will turn and you can remove it from the door.

2. Use a screwdriver: If the cylinder has a slot on the face, you may be able to use a screwdriver to turn it. Insert the screwdriver into the slot and turn it in the direction that would unlock the door. Again, if you are lucky, the cylinder will turn and you can remove it from the door.

3. Drill out the cylinder: If neither of the above methods work, you may need to drill out the cylinder. This is a last resort and should only be attempted if you are unable to remove the cylinder using the other methods. To drill out the cylinder, you will need a drill and a bit that is the same size or slightly larger than the cylinder. Drill straight into the center of the cylinder until it comes apart. Once the cylinder is removed, you should be able to turn the locking mechanism with a flathead screwdriver or other tool.

Note: If the mortise cylinder is part of a locking mechanism, be sure to take appropriate safety precautions and follow any relevant laws and regulations. It may be best to contact a professional locksmith to assist with the removal.

How to change mortise lock cylinder?

Changing a mortise lock cylinder 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.

By following these steps, you should be able to change the mortise lock cylinder 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.
