To adjust locks left and right, follow these steps:

1. Identify the lock mechanism: Determine if the lock is a mortise lock, a cylindrical lock, or a deadbolt.

2. Check the lock's orientation: Ensure the lock is properly aligned with the door and frame.

3. Adjust the lock's position: Loosen the set screws or bolts that secure the lock to the door or frame.

4. Move the lock: Gently slide the lock to the desired position, ensuring it is level and square with the door and frame.

5. Tighten the set screws or bolts: Secure the lock in place by tightening the set screws or bolts.

6. Test the lock: Verify that the lock operates smoothly and securely.

Adjusting locks left and right is crucial for ensuring proper alignment and functionality. Misaligned locks can lead to difficulty in operation, increased wear and tear, and potential security risks. According to a study by the National Burglar and Fire Alarm Association (NBFAA), approximately 30% of all residential burglaries involve forced entry through unlocked doors or windows. Properly adjusted locks can significantly reduce the risk of such incidents.
