Automotive Locksmithing Flashcards

What information does a locksmith typically need to verify before performing an automotive lockout or key service?

Answer: Proof of ownership (registration or title) and government-issued ID matching the vehicle owner

Locksmiths should verify proof of ownership (registration or title) and a matching ID to confirm the requester is the legal owner before servicing a vehicle.

Which Ford vehicle system uses a resistor pellet embedded in the key to provide a basic form of ignition security?

Answer: PATS (Passive Anti-Theft System) predecessor — Ford's resistor key system

Earlier Ford vehicles used a resistor key system where a resistor pellet in the key blade sent a resistance value to the ignition module to allow starting — an early precursor to transponder systems.

What does 'cloning' a transponder key mean, and why is it important for automotive locksmiths?

Answer: Copying the transponder chip's crypto ID to a blank chip without accessing the vehicle's ECU, allowing a duplicate key to start the car

Cloning copies the transponder's fixed code to a cloneable blank, creating a working duplicate without needing to access or modify the vehicle's immobilizer programming.

Which key machine type uses a stylus to trace an existing key and reproduce the cuts on a blank?

Answer: Mechanical duplicator (pantograph-style)

A mechanical duplicator or pantograph machine traces an existing key with a stylus, mechanically transferring the cut pattern to a blank key simultaneously.

What is a 'high-security automotive key' that requires an automotive locksmith to be factory-authorized or have specific tooling to duplicate?

Answer: A key with patent-protected cuts and an embedded transponder that cannot be cut or programmed without specific licensed equipment

High-security automotive keys (e.g., Medeco, Mul-T-Lock ignition-grade) have patent-protected keyways and cuts, requiring licensed cutters and authorized dealers to duplicate or program.

What does it mean to 'virginize' an immobilizer module during automotive key programming?

Answer: To reset the immobilizer ECU to its factory unprogrammed state so new keys can be learned from scratch

Virginizing resets the immobilizer to its factory blank state, erasing all previously programmed keys and allowing the technician to program an entirely new set of keys.
