Oklahoma Locksmith Practice Exam

What can cause difficulty in inserting or removing a key blank during impressioning?

1. Incorrect terminal settings

2. Using excessive force

3. Improperly lubricating the lock

4. Poor quality key blanks

The correct answer is: Improperly lubricating the lock

Improperly lubricating the lock can indeed lead to difficulties in inserting or removing a key blank during the impressioning process. Lubrication is critical in ensuring that the moving parts within the lock operate smoothly. If the lock is not adequately lubricated, the internal components may create friction, making it challenging to insert or remove the key blank. This can cause the key blank to stick or bind within the lock, potentially damaging both the key and the lock mechanism over time. While terminal settings, excessive force, and key blank quality can also impact the key insertion process, they do not directly relate to the lubrication of the lock itself, which is essential for maintaining smooth operation. Proper maintenance and lubrication are crucial aspects of locksmithing that can significantly affect the ease of working with locks during impressioning or other procedures.
