CAL — Certified Automotive Locksmith — Questions and Answers

Question 1: What is the recommended practice when an automotive locksmith cannot confirm a vehicle's ownership on a service call?

Proceed with service and document the uncertainty
Call the manufacturer for authorization
Perform the service and notify police afterward
Decline to perform the service until ownership can be verified (Correct answer)

Correct answer: Decline to perform the service until ownership can be verified

If ownership cannot be confirmed, the locksmith should decline service to avoid potential legal liability for facilitating vehicle theft.

Question 2: What is the primary purpose of a depth and space gauge in automotive key cutting?

To program transponder chips
To measure existing key cuts and verify cutting machine accuracy (Correct answer)
To test the tensile strength of key blanks
To remove broken key fragments from locks

Correct answer: To measure existing key cuts and verify cutting machine accuracy

A depth and space gauge allows locksmiths to measure the precise depth and spacing of cuts on an existing key or to verify the accuracy of a newly cut key.

Question 3: What is 'frequency hopping' and why is it relevant to automotive key fob security?

An alarm response where the horn chirps at varying frequencies to attract attention
The process of switching between backup frequencies when the primary signal is blocked
A method of increasing key fob range by hopping between cellular towers
A technique where the transmission frequency changes pseudo-randomly to prevent signal interception and jamming (Correct answer)

Correct answer: A technique where the transmission frequency changes pseudo-randomly to prevent signal interception and jamming

Frequency hopping spread spectrum (FHSS) rapidly switches transmission frequencies, making it difficult for attackers to intercept or jam the signal.

Question 4: When using a code machine to originate an ignition key by code, the locksmith inputs the key code and the machine produces a key. What is the key code derived from?

The owner's driver's license number
The cylinder's serial number stamped on the housing
The vehicle's VIN only
Manufacturer bitting code databases cross-referenced to the vehicle's key code tag or record (Correct answer)

Correct answer: Manufacturer bitting code databases cross-referenced to the vehicle's key code tag or record

Key codes are stored in manufacturer databases indexed by key code numbers found on dealer records, code tags, or code books, and they translate directly into the bitting sequence to be cut.

Question 5: Which of the following best describes the 'maximum adjacent cut specification' (MACS) rule in key cutting?

The maximum number of cuts allowed on a single key
The maximum blade thickness allowed for a given keyway
The furthest distance the key tip can be from the last cut
The largest allowable depth difference between any two adjacent cuts on a key (Correct answer)

Correct answer: The largest allowable depth difference between any two adjacent cuts on a key

MACS defines the greatest permitted depth difference between neighboring cuts; exceeding it can cause the key to bind or break in the lock.

Question 6: An automotive locksmith in the US who copies a high-security key for a customer without verifying ownership could potentially be held liable under which legal concept?

Only minor regulatory fines
Civil liability and potentially criminal accessory charges (Correct answer)
Federal telecommunications violations
No liability since the customer assumed all responsibility

Correct answer: Civil liability and potentially criminal accessory charges

Failing to verify ownership before duplicating keys can expose a locksmith to civil lawsuits and criminal accessory charges if the key is used in a theft.

Question 7: A customer reports their transponder key starts the car only when held at a specific angle near the ignition. What is the most likely cause?

Weak key battery
Faulty ignition lock cylinder
Corrupted PCM memory
Damaged transponder antenna ring (Correct answer)

Correct answer: Damaged transponder antenna ring

A damaged or partially broken antenna ring creates dead spots that require the key to be positioned precisely to achieve proper transponder communication.

Question 8: What is the primary purpose of the antenna ring surrounding the ignition cylinder?

To detect key insertion mechanically
To amplify the RF signal to the BCM
To energize and communicate with the transponder chip (Correct answer)
To power the ECU during startup

Correct answer: To energize and communicate with the transponder chip

The antenna ring creates an electromagnetic field that inductively powers and reads the transponder chip inside the key.

Question 9: On vehicles equipped with a passive entry system (PEPS), what happens to the door lock mechanism when the key fob is detected inside the vehicle?

Nothing changes; PEPS only affects the ignition
The system disables all power lock functions as a theft deterrent
The exterior door handles may be disabled to prevent accidental entry without the fob (Correct answer)
The ignition is cut off remotely by the manufacturer

Correct answer: The exterior door handles may be disabled to prevent accidental entry without the fob

Some PEPS systems detect the fob inside and inhibit the exterior passive-entry handle sensors to prevent confusion, meaning physical key or locksmith tools are needed to enter.

Question 10: What is the primary difference between an OBD-II key programmer and a standalone key programmer?

OBD-II programmers connect via the vehicle's diagnostic port, while standalone units may work without a working key or OBD access (Correct answer)
OBD-II programmers require dismantling the dashboard
OBD-II programmers work only on foreign vehicles
Standalone programmers are only used for remote fobs

Correct answer: OBD-II programmers connect via the vehicle's diagnostic port, while standalone units may work without a working key or OBD access

OBD-II programmers connect through the diagnostic port and often require at least one working key, while standalone programmers can work via direct ECU connection or other bypass methods when no working key exists.

Question 11: Why is key programming often required after ignition cylinder replacement?

To disable the vehicle alarm
To sync the key with the new ignition system (Correct answer)
To calibrate the speedometer
To reset the fuel pump

Correct answer: To sync the key with the new ignition system

Modern vehicles use immobilizer systems that require the key to be reprogrammed to communicate with the new ignition cylinder.

Question 12: A locksmith needs to generate a key for a 2005 Toyota Camry with no working keys. After cutting the mechanical key, the next step specific to this vehicle is:

Reprogramming the BCM with a J2534 device
Using a resistor bypass to temporarily disable the transponder
Replacing the ignition switch to bypass the immobilizer
Programming the transponder chip using an EEPROM reader or compatible programmer (Correct answer)

Correct answer: Programming the transponder chip using an EEPROM reader or compatible programmer

Toyota Camry of that era uses transponder immobilizer technology requiring the new key's chip to be programmed to the vehicle's ECU.

Question 13: Which of the following best describes a 'smart key' system compared to a standard transponder key?

A smart key requires annual reprogramming at a dealership, while a transponder key is permanent
A smart key uses a longer RF range for remote start from up to one mile away
A smart key uses active RF communication for passive entry and push-button start without inserting the key, while a transponder key must be physically inserted (Correct answer)
A smart key contains a microprocessor that can update its own firmware, while a transponder key is read-only

Correct answer: A smart key uses active RF communication for passive entry and push-button start without inserting the key, while a transponder key must be physically inserted

Smart key systems (PKE) allow entry and ignition without inserting the key by using active RF signals, unlike transponder keys that require physical insertion for the coil to read the chip.

Question 14: What is the function of a 'key learning' or 'key registration' procedure performed via OBD-II?

To physically cut the key blade profile
To reset the odometer to zero
To add a new transponder's ID to the vehicle's authorized list (Correct answer)
To update the vehicle's firmware

Correct answer: To add a new transponder's ID to the vehicle's authorized list

OBD-II key learning writes the new transponder's unique ID into the immobilizer control module's approved key list.

Question 15: What is the purpose of a 'J' tool in automotive lockout work?

To measure the depth of a key cut
To decode a lock cylinder without disassembly
To hook and pull interior door handles or lock knobs (Correct answer)
To cut new keys by code

Correct answer: To hook and pull interior door handles or lock knobs

The 'J' tool is a long-reach hook-shaped rod inserted through a gap to snag and pull vertical lock buttons or interior door handles.

Question 16: When selecting a pinning tray for rekeying an automotive lock cylinder, what is its main purpose?

Storing key blanks sorted by manufacturer
Holding driver pins, springs, and key pins in organized rows to prevent mixing during disassembly and reassembly (Correct answer)
Testing transponder chip frequencies
Measuring the depth of existing key cuts

Correct answer: Holding driver pins, springs, and key pins in organized rows to prevent mixing during disassembly and reassembly

A pinning tray keeps the small components of a lock cylinder (driver pins, key pins, and springs) organized by position so they are not mixed up or lost during rekeying.

Question 17: Which tool is commonly used to clone a fixed-code (non-rolling-code) transponder key without programming access to the vehicle?

TPMS sensor tool
OBD2 scanner
Transponder cloner (e.g., CN900 or similar) (Correct answer)
Immobilizer bypass module

Correct answer: Transponder cloner (e.g., CN900 or similar)

A transponder cloner reads the data from a working transponder key and writes an exact copy to a compatible blank chip, allowing duplication of fixed-code transponders without vehicle access.

Question 18: Which safety precaution is most critical when removing a tilt steering column ignition lock cylinder on an older GM vehicle with a column-mounted airbag?

Keep the key in the ON position throughout removal
Cover the airbag module with a rubber mat
Remove the airbag fuse only—no battery disconnect needed
Disconnect the battery and wait at least 10 minutes before working near the airbag (Correct answer)

Correct answer: Disconnect the battery and wait at least 10 minutes before working near the airbag

Airbag systems retain capacitor charge for several minutes after battery disconnect; waiting at least 10 minutes ensures the capacitors are fully discharged and accidental deployment cannot occur.

Question 19: Which of the following best describes the 'under-the-door' technique for vehicle entry?

Using a flexible reach tool inserted through the bottom weather seal gap to operate interior controls (Correct answer)
Sliding a flat bar under the door sill to pop the lock rod upward
Accessing the lock cylinder through a hole drilled under the door handle
Removing the door threshold trim to expose the lock linkage

Correct answer: Using a flexible reach tool inserted through the bottom weather seal gap to operate interior controls

The under-door technique uses a flexible rod inserted through the rubber weather seal gap at the door base to reach up and operate the interior lock button or handle.

Question 20: Which of the following best describes 'in-circuit' EEPROM programming?

Programming the chip after removing it from the PCB
Reading or writing to the chip while it remains soldered on the board (Correct answer)
Cloning one chip to another using a chip duplicator
Programming via the vehicle's OBD-II port exclusively

Correct answer: Reading or writing to the chip while it remains soldered on the board

In-circuit programming reads or writes to the EEPROM chip while it remains soldered on the PCB, using clip adapters to access the chip pins.

Question 21: What is the primary reason automotive locksmiths must document the odometer reading when servicing a vehicle?

To provide a reference point that the vehicle was in their possession at a specific mileage, limiting liability claims (Correct answer)
To satisfy insurance underwriting requirements
To calculate proper oil change intervals
To comply with EPA emissions reporting

Correct answer: To provide a reference point that the vehicle was in their possession at a specific mileage, limiting liability claims

Recording odometer mileage establishes a time-stamped record of the vehicle's condition when in the locksmith's care, limiting liability for pre-existing damage claims.

Question 22: What does 'NASTF Vehicle Security Professional (VSP) registration' allow automotive locksmiths to access?

Access to manufacturer recall databases
Free OEM diagnostic tools for all makes
OEM security data, key codes, and programming procedures for modern vehicles (Correct answer)
Direct dealer wholesale parts pricing

Correct answer: OEM security data, key codes, and programming procedures for modern vehicles

NASTF VSP registration grants vetted professionals access to OEM security information including key codes and immobilizer programming procedures.

Question 23: A locksmith is cutting a high-security Medeco or Mul-T-Lock key blank on a standard code-cutting machine. What additional feature of these keys cannot be replicated by depth-only code cutting?

The angular rotation (rotation or sidebar position) of each cut, which requires specialized equipment (Correct answer)
The material hardness of the blank
The key's overall length
The key's bow shape

Correct answer: The angular rotation (rotation or sidebar position) of each cut, which requires specialized equipment

High-security keys like Medeco use angled cuts that interact with a sidebar mechanism; standard code cutters only control depth, not the rotational angle of each cut.

Question 24: Which term describes the bitting specification that a manufacturer assigns to each key blank, indicating the maximum and minimum cut depths and their increments?

Key code
Keyway profile
Bitting list
Depth and space specification (Correct answer)

Correct answer: Depth and space specification

Depth and space specifications define the exact dimensions (depths and spacing between cuts) a manufacturer uses for a key series, ensuring cuts fall within tolerances the lock can operate.

Question 25: When drilling out a damaged ignition lock cylinder, at what component must the locksmith stop drilling to avoid further damage?

The ignition electrical switch assembly (Correct answer)
The retainer clip
The shear line between the plug and housing
The steering column shaft

Correct answer: The ignition electrical switch assembly

Drilling must be stopped at the back of the lock housing to avoid destroying the ignition electrical switch assembly, which would require additional replacement.

Question 26: When cutting a Tibbe key (used on some Ford and Jaguar models), which characteristic makes it different from conventional keys?

It has cuts only on the tip of the key
It requires a specialized heated cutter due to its titanium alloy composition
It has a round profile with angled cuts at set rotation positions around the blade (Correct answer)
It uses a double-sided bitting pattern with 12 cuts per side

Correct answer: It has a round profile with angled cuts at set rotation positions around the blade

Tibbe keys have a cylindrical (round) blade with cuts at specific rotational positions rather than the flat-blade edge cuts of conventional keys.
