C. Replace the entire lockset
D. Duplicate the key and test it
Verifying identity and authority before performing locksmith work protects the property

manipulating the locking device.
2. Under British Columbia's Security Services Regulation, which category specifically
covers a person performing locksmith work?

The regulation identifies a specific security worker licence type for locksmiths. The locksmith
category includes performing locksmith services and specified electronic locking and property-
protection activities.

are authorized to enter the premises. What is the most appropriate response?
A. Proceed if the customer knows the office number
B. Open the door only if the customer pays in cash
C. Proceed after obtaining a verbal description of the contents
D. Decline the opening until satisfactory authorization is established
A locksmith should not rely solely on a customer's verbal claim of ownership or occupancy.
Establishing authorization is an essential professional and risk-management practice.
,4. Which component of a conventional pin-tumbler cylinder normally contains the
chambers that house the key pins and driver pins?
A. Plug
B. Cam
C. Housing
D. Tailpiece
The cylinder housing contains the pin chambers. The plug rotates within the housing when
the correct key aligns the pin stacks at the shear line.
5. In a conventional pin-tumbler lock, what occurs when the correct key is fully inserted?
A. All springs are compressed permanently
B. The pin interfaces align at the shear line, allowing the plug to rotate
C. The cylinder housing separates from the lock body
D. The latch automatically retracts without plug rotation
The correct key positions the key pins and driver pins so that their interface aligns with the
shear line. This permits the plug to rotate and operate the lock mechanism.
6. A key operates a cylinder but requires excessive force to turn. Which should the
locksmith investigate FIRST?
A. Door and latch alignment
B. Key bow thickness only
C. Restricted-key registration
D. Rekeying authorization
A misaligned door, latch, or strike can place side loading on the locking mechanism and make
the key difficult to turn. Mechanical alignment should be checked before assuming the
cylinder itself has failed.
7. What is the primary function of a deadlatch or auxiliary latch on many commercial door
locks?
A. Increase key duplication speed
B. Prevent unauthorized manipulation of the latch when the door is closed
,C. Eliminate the need for a strike plate
D. Convert a cylinder into an electronic lock
The auxiliary latch is designed to help prevent the latch from being manipulated when the
door is closed and properly seated against the frame.
8. A locksmith notices that the strike plate is loose and the latch is contacting its edge
rather than entering the opening cleanly. What is the most appropriate corrective action?
A. Cut a new key
B. Replace the cylinder immediately
C. Correct the strike and door alignment
D. Remove the latch
A latch that contacts the strike incorrectly indicates an alignment problem. Correcting the
strike position and door alignment can restore proper operation without unnecessary cylinder
replacement.
9. Which measurement is most directly associated with determining whether a replacement
lock will fit an existing door preparation?
A. Paint thickness
B. Door swing only
C. Hinge finish
D. Backset
Backset is the distance from the edge of the door to the centreline of the lock or latch. It is a
critical measurement when selecting compatible hardware.
10. A customer presents a key that appears heavily worn and reports intermittent
operation. What is the best initial diagnostic approach?
A. Examine the key for wear and compare it with a known-good key or decode
B. Drill the lock
C. Replace every component in the door
D. Lubricate the key and return it without testing
A worn key can cause inconsistent alignment of the lock's pin stacks. Comparing the key with
a known-good key helps distinguish key wear from a cylinder or door problem.
, 11. What is the main purpose of rekeying a lock cylinder?
A. Change the door's handing
B. Change the physical size of the door
C. Change the key combination while retaining compatible hardware
D. Increase the thickness of the strike plate
Rekeying changes the internal pin configuration so an existing cylinder operates with a
different key. It can provide key-control benefits without replacing the complete lock.
12. A business manager wants former employees' keys to stop working while keeping the
existing lock hardware. Which service is generally most appropriate?
A. Door replacement
B. Rekeying
C. Hinge replacement
D. Strike removal
Rekeying can invalidate previously issued keys while allowing the existing compatible lock
hardware to remain in service.
13. Which practice provides the strongest protection when managing a restricted key
system?
A. Cutting duplicates for anyone who requests them
B. Keeping a controlled record of authorized key issuance and duplication
C. Leaving the code card in the customer's vehicle
D. Allowing verbal authorization from unknown callers
Restricted key systems depend on controlled duplication and authorization. Accurate records
help prevent unauthorized keys from entering the system.

restricted key?
A. Any person who possesses the original key
B. Any tenant in the building
