Question 1: What are the main internal components of a pin tumbler lock?
- Levers, cams, and tension springs
- Driver pins, key pins, springs, plug, and outer shell (Correct answer)
- Wafers, cams, and actuators
- Discs, detents, and a rotating core
Correct answer: Driver pins, key pins, springs, plug, and outer shell
A pin tumbler lock operates with driver pins, key pins, springs, a rotating plug, and an outer shell that together allow or prevent the plug from rotating.
Question 2: What does key cutting mean in locksmithing?
- Physically removing a lock from a door
- Duplicating or originating a key by machining cuts to specific depths on a blank (Correct answer)
- Breaking the tip off a key for extraction
- Filing down lock pins to match an existing key
Correct answer: Duplicating or originating a key by machining cuts to specific depths on a blank
Key cutting involves using a key cutting machine to produce specific depth cuts on a key blank that correspond to the lock's pin configuration.
Question 3: What two tools are used for lock picking?
- Tension wrench and pick (Correct answer)
- Screwdriver and probe
- Drill and extractor
- Hammer and punch
Correct answer: Tension wrench and pick
Lock picking uses a tension wrench to apply light rotational pressure to the plug while a pick manipulates the pins to align at the shear line one by one.
Question 4: What defines a deadbolt lock?
- An electronic lock with a motorized bolt
- A bolt that requires a key or thumb turn to operate and has no spring mechanism (Correct answer)
- A padlock with a hardened shackle
- A cam lock used in cabinets
Correct answer: A bolt that requires a key or thumb turn to operate and has no spring mechanism
A deadbolt requires deliberate operation by key or thumb turn and has no spring mechanism, making it more resistant to forced entry than a spring latch.
Question 5: What is key control?
- Making multiple copies of keys for convenience
- A security system restricting unauthorized duplication and tracking key distribution (Correct answer)
- A purely electronic key management solution
- The process of removing compromised keys from service
Correct answer: A security system restricting unauthorized duplication and tracking key distribution
Key control is a security system that restricts unauthorized key duplication and tracks which keys have been issued and to whom.
Question 6: What is re-keying a lock?
- Replacing the entire lock cylinder and hardware
- Changing the internal pin configuration so a new key operates it (Correct answer)
- Duplicating the existing key set
- Repairing a damaged lock mechanism
Correct answer: Changing the internal pin configuration so a new key operates it
Re-keying changes the internal pin heights of a lock so that only a new key operates it, while the existing lock hardware remains in the door.
