QUESTION 1.
A property manager requests that every tenant unit in a multi-building apartment
complex be rekeyed while preserving emergency access by maintenance personnel.
During planning, you discover that several buildings have undocumented keying
changes completed by previous contractors. What is the MOST appropriate first step?
A. Install new cylinders immediately using the existing master key hierarchy.
B. Develop and verify a complete key system inventory before designing the new
master key structure.
C. Issue temporary master keys and update records after installation.
D. Rekey only units with documented key records.
Correct Answer: B. Develop and verify a complete key system inventory before
designing the new master key structure.
Explanation: A verified inventory prevents incompatible pinning schedules,
unintended cross-keying, and security gaps. Designing a master key system without
confirming existing hardware and undocumented changes can create operational
and security failures. The other options either perpetuate inaccurate records or
produce inconsistent key control.

QUESTION 2.
During a commercial lock installation, an exit door equipped with panic hardware fails
to latch consistently after the frame settles. Which corrective action BEST preserves
both security and life-safety requirements?
A. Disable the latch until structural repairs are completed.
B. Increase spring pressure within the panic device.
C. Adjust door alignment and hardware so the latch engages fully without impeding
,free egress.
D. Replace the panic hardware with a double-cylinder deadbolt.
Correct Answer: C. Adjust door alignment and hardware so the latch engages
fully without impeding free egress.
Explanation: Proper alignment restores reliable latching while maintaining
unobstructed emergency egress. Disabling the latch compromises security, increasing
spring pressure does not address alignment problems, and replacing panic hardware
with a double-cylinder deadbolt may violate life-safety requirements.

QUESTION 3.
A business owner requests duplicate keys marked "Do Not Duplicate" for an employee
who lacks written authorization. What represents the MOST appropriate professional
response?
A. Produce the duplicates because the employee possesses the original key.
B. Produce only one duplicate to reduce security risk.
C. Decline the request until proper authorization is verified.
D. Remove the marking before duplicating the key.
Correct Answer: C. Decline the request until proper authorization is verified.
Explanation: Responsible key control requires confirming authorization before
duplicating restricted or controlled keys. Possession alone does not establish
authority, and altering or ignoring key markings undermines security practices and
professional ethics.

QUESTION 4.
While troubleshooting a pin tumbler cylinder, the plug rotates only intermittently after
rekeying. Driver pins, springs, and key pins match the intended bitting. Which
condition is MOST likely responsible?
, A. Excessive lubricant on the key blade.
B. Incorrect key bow design.
C. A worn plug causing inconsistent shear line alignment.
D. A decorative faceplate installed upside down.
Correct Answer: C. A worn plug causing inconsistent shear line alignment.
Explanation: Excessive wear within the plug or shell can prevent pins from aligning
consistently at the shear line despite correct pinning. Lubrication, bow style, and
faceplate orientation are unlikely to create intermittent shear-line alignment
problems.

QUESTION 5.
A healthcare facility requires rapid emergency access while maintaining strict
departmental key control. Which master key strategy BEST balances operational
efficiency with security?
A. A carefully documented tiered master key hierarchy with limited issuance and
periodic auditing.
B. One grand master key issued to every department supervisor.
C. Independent change keys with no master key capability.
D. Universal keyed-alike cylinders throughout the facility.
Correct Answer: A. A carefully documented tiered master key hierarchy with
limited issuance and periodic auditing.
Explanation: A structured hierarchy limits access according to operational need while
preserving emergency capabilities and accountability. Broad distribution of master
keys or universal keying greatly increases risk, while eliminating master functionality
can hinder emergency response.

QUESTION 6.
After replacing a commercial mortise lock, the customer reports that the latch retracts
normally but the deadbolt occasionally binds. What should be evaluated FIRST?
