1. A technician is preparing to service a Class B combination safe that
uses a mechanical dial lock. The customer complains that the lock
does not rotate smoothly. Upon inspection, the drive cam feels stiff
and slightly worn. Which of the following is the most appropriate first
step to correct this issue?
A. Replace the entire lock assembly with a new electronic lock
B. Remove the dial and inspect the drive cam, spindle, and bushing;
then clean and lightly lubricate with a dry graphite lubricant
C. Apply oil-based lubricant directly on the dial mechanism while the
lock remains installed
D. Adjust the boltwork to compensate for the stiffness
Rationale: A mechanical safe lock should be disassembled for
inspection of worn parts, and the appropriate dry lubricant applied
to reduce friction without attracting debris._
2. A customer’s deposit safe features a time delay lock and they report
the delay period has increased well beyond specifications, causing
operational delay. What is the most common reason for the extended
delay?
A. Corroded bolts
B. Worn time delay motor gear train or dried lubricants inhibiting
movement
C. Incorrect combination entered
, D. Loose door hinges
Rationale: Excessive delay is often due to mechanical wear inside the
time delay motor or gears and old/dry lubrication, which slows
actuator response._
3. During a service call, you find that the safe’s electronic lock keypad
registers false presses when touched lightly. Which is the most
probable cause?
A. Dead battery only
B. Faulty power supply
C. Contaminated keypad contacts due to dust, moisture, or corrosion
D. Incorrect combination programming
Rationale: False key registrations are typically due to contaminants
on the keypad membrane interfering with proper switch contact._
4. A safe technician must re-program an electronic lock after a battery
failure. What is the first required verification step before
programming?
A. Test door alignment
B. Remove the lock from the safe
C. Confirm the lock model and check that the correct master code is
available
D. Replace all internal bolts
Rationale: Verifying the exact lock model and availability of master
code ensures that programming proceeds with correct parameters
and avoids lockout._
5. A UL TL-15 rated safe is being serviced for a hardened steel plate near
the combination lock that has worn burrs. Why must these burrs be
carefully removed and the surface maintained?
A. They enhance security
B. They improve aesthetics only
C. To prevent interference with lock operation and ensure consistent
dial interaction under attack conditions
D. To allow use of oil-based lubricants
Rationale: Burrs can catch or bind the dial mechanism, interfering
with safe opening and undermining design integrity under rated
conditions._
, 6. A deposit safe’s drop slot has become misaligned, jamming envelopes
as they are inserted. What is a likely correct adjustment?
A. Increase the tension on the primary boltwork
B. Adjust the inner drop chute guide screws and ensure the slot
frame is square and lubricated
C. Replace all door bolts
D. Reprogram time delay lock
Rationale: Misalignment of the drop chute likely comes from shifted
guides or fasteners; correcting their alignment solves the jam issue._
7. On a high-security safe with a Group II mechanical lock, the customer
reports that the combination has been forgotten. Under Arizona
regulations, what is the documented proof a technician must obtain
before initiating combination retrieval?
A. Company letterhead alone
B. A verbal authorization
C. Government-issued ID and proof of ownership documentation
D. Police report only
Rationale: Technicians must verify identity and legal ownership
before sensitive combination retrieval to prevent unauthorized
access._
8. When installing a new safe in a commercial environment, local code
requires anchoring. Which anchoring method provides the highest
level of compliance for a steel floor?
A. Adhesive pads
B. Light screws
C. Heavy-duty expansion anchors into the concrete slab or grade
beam identified in specifications
D. No anchor required
Rationale: Heavy anchors into structural concrete provide the secure
anchoring required by most safe installation codes for commercial
applications._
9. A technician is troubleshooting a safe’s audit trail feature on an
electronic lock. Users report events are not being logged. Which is the
most appropriate diagnostic step?
A. Reinstall batteries
