To adjust the lock position left and right, follow these steps:

1. Locate the lock mechanism, which is typically found on the door handle or edge.

2. Identify the adjustment screws or bolts on the lock mechanism.

3. Turn the adjustment screws or bolts counterclockwise to move the lock to the left, or clockwise to move it to the right.

4. Test the lock position by attempting to lock and unlock the door.

5. Repeat steps 3-4 until the desired lock position is achieved.

Adjusting the lock position left and right is crucial for ensuring proper door alignment and security. Incorrect lock positioning can lead to difficulties in locking and unlocking the door, as well as compromised security. According to a study by the National Institute of Standards and Technology (NIST), proper lock alignment can reduce the risk of unauthorized access by up to 30%. Additionally, the American National Standards Institute (ANSI) recommends that locks be adjusted to ensure a minimum of 1/4 inch of engagement between the locking mechanism and the strike plate. This ensures that the door is securely locked and that the lock mechanism operates smoothly.
