Adjusting Your Lock Cylinder

The following steps outline how to adjust a door lock cylinder:

Locate the Screw: Identify the screw that secures the lock cylinder. This screw is usually located on the edge of the door, close to the lock cylinder itself.
Loosen the Screw: Use a screwdriver to turn the screw anti-clockwise by a quarter of a turn. This action will loosen the screw slightly and not remove it entirely.
Move the Cylinder: Loosening the screw enables the lock cylinder to move up and down freely from its center point. You should now be able to adjust the cylinder.

Adjusting the lock cylinder might be necessary for a variety of reasons, including:

Sticking or Difficulty Turning: If the key is hard to insert or turn, a slight adjustment can sometimes correct the alignment issue.
New Door Installation: When installing a new door, the lock cylinder might need adjustment for proper functionality.

Ensure not to remove the screw entirely. You only want to loosen it so the cylinder has room to move.
