Pick guns work by:
- A.
Crushing the springs
- B.
Bouncing the top pins above the shear line
- C.
Clicking all pins above the shear line
- D.
Bouncing the bottom pins above the shear line
Correct Answer
B. Bouncing the top pins above the shear lineExplanation
Pick guns work by bouncing the top pins above the shear line. The shear line is the line where the inner and outer cylinder of a lock meet. When the top pins are lifted above the shear line, the lock's cylinder can rotate freely, allowing the lock to be opened. The pick gun achieves this by rapidly striking the bottom pins, causing the top pins to jump and momentarily clear the shear line. This creates a brief window of opportunity to rotate the cylinder and unlock the lock.Rate this question:

Correct Answer
A. Improper lubricating the lockExplanation
Difficulty inserting or removing the key blank during impressioning is caused by improper lubricating the lock.

Of the following materials, which key blank produces the most obvious marks?
- A.
Nickel silver
- B.
Brass
- C.
Cobalt
- D.
Steel
Correct Answer
B. BrassExplanation
Brass is the correct answer because it is a softer material compared to the other options listed. When a key is inserted into a brass blank, it will leave more noticeable marks due to its softer composition. This is because brass is more easily scratched or indented, making the marks more obvious and visible. Nickel silver, cobalt, and steel are all harder materials, so the marks left on them would be less prominent and not as easily noticeable.Rate this question:
