What should you do when resetting a lock?

  1. Test the lock mechanism

  2. Lubricate the key

  3. Replace the lock battery

  4. Adjust the locking mechanism

The correct answer is: Lubricate the key

When resetting a lock, it's essential to ensure that all components are functioning correctly. Lubricating the key is important since it can help maintain smooth operation within the lock mechanism. A well-lubricated key can prevent wear and tear on the lock and ensures that it turns easily without jamming. Testing the lock mechanism is also a valuable step when resetting a lock, as it allows you to confirm that the lock is functioning properly after the reset. However, lubrication should be performed as part of routine maintenance to promote optimal operation. Changing the lock battery may be necessary for electronic locks, but this step alone isn’t directly tied to the resetting process. Adjusting the locking mechanism can be critical if there are alignment issues, yet that is a separate task from resetting the lock itself. In summary, lubricating the key is a key maintenance practice that supports the overall functionality of a lock when it is reset.
