SECTION ONE: QUESTIONS 1–100
1. Which of the following is the primary purpose of a master key system?
A. To allow a single key to open all locks in a facility regardless of their bitting
B. To provide a hierarchical access structure where one key can operate multiple locks
C. To ensure all locks within a building can be opened with the same change key
D. To create a system where each key is unique and cannot be duplicated
🟢 B. To provide a hierarchical access structure where one key can operate multiple locks
🔴 Explanation: A master key system is designed to provide a structured hierarchy of access. A master
key operates a group of locks that each have their own individual change keys, allowing for convenient
access for supervisory personnel while maintaining security for individual users.
2. When decoding a wafer lock, a locksmith notices that all wafers are spring-loaded. This indicates
the lock is most likely a:
A. Disc tumbler lock
B. Wafer tumbler lock
C. Pin tumbler lock
D. Lever lock
,🟢 B. Wafer tumbler lock
🔴 Explanation: Spring-loaded wafers are a defining characteristic of the wafer tumbler mechanism. In
pin tumbler locks, the driver pins are spring-loaded, not the key pins. Lever locks use a set of levers,
and disc tumblers have a rotating disc mechanism, making wafer tumbler the correct identification.
3. Under the British Columbia Security Services Act, a locksmith must maintain records of key
duplication and sales for what minimum period?
A. 6 months
B. 1 year
C. 2 years
D. 5 years
🟢 C. 2 years
🔴 Explanation: The Security Services Act requires licensed locksmiths to maintain detailed records of
key duplication and all related transactions for a minimum of two years. This regulation helps law
enforcement investigate crimes and ensures traceability of key requests.
4. A client has an electronic lock that uses a magnetic stripe card. The card fails to work, but the
door can be opened with a physical key. What is the most likely initial cause?
A. A failure of the lock's internal motor
B. A corrupted or demagnetized card
C. A loss of power to the lock
D. A jammed latch bolt
🟢 B. A corrupted or demagnetized card
🔴 Explanation: Since the physical key still operates the lock, the mechanical and electrical power
mechanisms are likely functional. The most logical and common cause for a mag stripe card failure is
that the card's magnetic stripe has become corrupted or demagnetized, requiring a new card to be
issued.
5. The Canadian Standards Association (CSA) sets standards for locks in Canada. Which of the
following is a key function of a CSA-approved deadbolt?
A. It must be made of brass to prevent corrosion
B. It must have a minimum 2-inch throw bolt
C. It must resist a specific amount of force and torque
D. It must be equipped with a keypad for access
🟢 C. It must resist a specific amount of force and torque
🔴 Explanation: CSA standards for locks, such as CSA B69, focus on security and durability. They
require deadbolts to pass rigorous tests for strength, resistance to prying and impact, and other forms
of attack. The minimum throw bolt length is typically 1 inch, not 2 inches, making C the most accurate
statement.
6. What is the correct order of pin stack components in a standard pin tumbler cylinder, from the
key to the top of the cylinder?
A. Top pin, bottom pin, spring
B. Spring, bottom pin, top pin
, C. Bottom pin, top pin, spring
D. Bottom pin, spring, top pin
🟢 C. Bottom pin, top pin, spring
🔴 Explanation: In a pin tumbler lock, the pin stack is arranged from the keyway upward as follows: the
bottom pin (which contacts the key), then the top pin (or driver pin), and finally the spring at the very
top of the chamber. This order is essential for the lock's operation, as the proper key lifts the bottom
pins to the shear line, separating them from the driver pins.
7. A locksmith is called to a property where the owner has lost all keys to a high-security mortise
lock. Which is the most appropriate and ethical first step for the locksmith?
A. Drill out the cylinder immediately to provide entry
B. Attempt to impression a key for the lock
C. Verify the identity and ownership of the client
D. Decode the existing lock by reading the pins
🟢 C. Verify the identity and ownership of the client
🔴 Explanation: Before any work is performed, especially when no keys are available for verification,
the locksmith's primary professional and legal obligation is to confirm that the client has the authority
to access the property. This may involve checking photo ID, property ownership documents, or a lease
agreement. Failure to do so could result in aiding an illegal entry.
8. Which keyway type is designed to restrict key blank availability to licensed locksmiths?
A. Paracentric keyway
B. Standard keyway
C. Restricted keyway
D. Warded keyway
🟢 C. Restricted keyway
🔴 Explanation: A restricted keyway is a patented or proprietary design where the key blanks are only
sold to authorized dealers or locksmiths. This restricts the ability for unauthorized individuals to
duplicate keys, thereby enhancing security and key control.
9. A property owner wants to install an access control system where different employees have
different schedules and access levels. The most appropriate hardware choice is a:
A. Mechanical cipher lock
B. Electromagnetic lock with a keypad and programmable controller
C. Single-sided deadbolt
D. Combination padlock
🟢 B. Electromagnetic lock with a keypad and programmable controller
🔴 Explanation: The core requirement is flexible, programmable access control. A keypad and
controller system can manage multiple users, schedules, and permissions. An electromagnetic lock
paired with this control allows for remote and electronic management, while the other options are
mechanical and do not offer flexible programming.
10. What is the function of the 'pegging' process in safe and vault lock manipulation?
A. It involves physically drilling a hole to view the lock's internal components.
