1. A homeowner reports that their front door lock is sticking and difficult
to turn. Upon inspection, you find that the pins are worn unevenly and
there is minor corrosion inside the cylinder. Which of the following is
the most appropriate first step to restore proper function?
A. Drill out the lock cylinder and replace it entirely
B. Lubricate the lock with graphite powder and reassemble
C. Replace all the pins with standard pins regardless of measurement
D. Disassemble the cylinder, clean corrosion, inspect and replace
worn pins, then reassemble
Rationale: The proper method involves careful disassembly, cleaning,
and replacing only worn components to restore function without
unnecessary replacement. Lubrication alone may not solve the issue
if pins are worn, and drilling should be a last resort.
2. When installing a commercial mortise lock, which of the following
factors is most critical for ensuring compliance with fire safety
regulations?
A. Using the heaviest lockset available
B. Ensuring the lock allows egress without keys from the inside
C. Selecting a lock with a decorative finish
D. Installing additional locking mechanisms on the door
, Rationale: Fire safety codes require that occupants can exit a
building without using keys, tools, or special knowledge. Mortise
locks must be configured to allow free egress in emergencies.
3. A client requests that you rekey all their exterior locks after moving
into a new home. The locks are all pin tumbler types. Which tool
combination is most appropriate for this task?
A. Pick set and tension wrench
B. Key gauge, pinning kit, and follower
C. Drill and replacement cylinder
D. Hammer and punch
Rationale: Rekeying pin tumbler locks requires a pinning kit to match
new keys, a follower to retain the plug while removing the cylinder,
and a key gauge to ensure proper pin sizing. Drilling is unnecessary
unless the lock is damaged.
4. While performing a lock audit at a commercial facility, you discover a
high-security cylinder with restricted keyway. Which statement best
describes the locksmith’s responsibility regarding key duplication?
A. Duplicate keys for convenience without authorization
B. Only duplicate keys using generic key blanks
C. Duplicate keys only according to manufacturer’s authorization and
control measures
D. Remove the lock to access key patterns for duplication
Rationale: High-security locks with restricted keyways are protected
by patent and manufacturer control. Unauthorized duplication
violates legal and ethical standards.
5. A safe requires combination resetting. The manufacturer provides a
change key and instructions. What is the correct procedure to reset
the combination?
A. Force the dial to the new combination without using the change key
B. Remove the lock entirely and manually adjust internal wheels
C. Insert the change key, follow manufacturer instructions, and
record the new combination securely
D. Guess the new combination until the safe opens
Rationale: Using the manufacturer-provided change key ensures that
, the internal wheels align correctly for the new combination,
preventing lockout and maintaining security.
6. You are called to service a door with an electronic keypad lock that
intermittently fails to grant access. After checking the batteries, you
notice no visible damage to the circuit board. Which step should you
take next?
A. Replace the entire lock assembly immediately
B. Reset the lock to factory settings and reprogram the access codes
C. Drill the lock open and replace the cylinder
D. Ignore the issue as it may resolve itself
Rationale: Intermittent electronic lock failures often result from
software or programming errors. Resetting to factory settings and
reprogramming codes can resolve these issues without unnecessary
hardware replacement.
7. When selecting a master key system for a multi-tenant office building,
which principle should guide the pinning of cylinders?
A. Each tenant uses the same key for all doors
B. Install padlocks instead of cylinders
C. Configure pin stacks to allow individual keys for tenants while
enabling a master key to access all cylinders
D. Use only one master key for the entire building without individual
tenant keys
Rationale: Master key systems require careful pinning so that
individual users have unique keys while the master key opens all
locks, maintaining both security and convenience.
8. A lock exhibits “key turning but bolt not retracting” symptoms.
Inspection reveals no internal obstruction. Which cause is most
probable?
A. Improper lubrication
B. Wrong key blank
C. Broken or disconnected cam inside the cylinder
D. Corrosion on the lock exterior
Rationale: If the key turns but the bolt does not retract, the cylinder
is turning freely without engaging the cam mechanism. Replacing or
repairing the cam restores function.
