Automotive Locksmithing Flashcards

What is the NASTF (National Automotive Service Task Force) Vehicle Security Professional (VSP) credential relevant to automotive locksmiths?

Answer: A credentialing program that allows vetted locksmiths to access OEM immobilizer security data and PIN codes

The NASTF VSP credential allows background-checked automotive locksmiths to access OEM security data portals for immobilizer PIN codes and security data needed for key programming.

Which tool category allows automotive locksmiths to read and write transponder data and program new keys to a vehicle's ECU?

Answer: Automotive key programmer / OBDII programmer

Automotive key programmers (such as Autel, Xhorse, or Advanced Diagnostics tools) connect via OBDII or direct to the immobilizer to read security data and program new transponder keys.

What is the purpose of a 'depth and space gauge' in automotive key cutting?

Answer: To measure the cut depths and spaces on an existing key or lock wafer to determine the bitting code

A depth and space gauge measures the precise cut depths and spacing on a key or wafer, allowing the locksmith to identify the bitting code without a code database.

What is a 'proximity key' or 'smart key' in modern vehicles?

Answer: A key fob that communicates with the vehicle wirelessly and allows push-button starting without inserting a key

Proximity (smart) keys use low-frequency radio communication to authenticate with the vehicle when the fob is nearby, enabling keyless entry and push-button start.

Which automotive ignition issue is described as a cylinder that turns but does not engage the starter or accessory position properly?

Answer: Worn ignition wafers or a damaged ignition actuator

Worn ignition wafers or a damaged actuator prevent the cylinder from properly engaging ignition switch positions, requiring cylinder replacement or repair.

When performing an automotive lockout service on a newer vehicle, why should locksmiths avoid using metal Slim Jim tools on most modern cars?

Answer: They can damage wiring, airbag sensors, and weather stripping, and may trigger airbag deployment

Modern vehicles route airbag wiring and complex electronic linkages through the door, making metal Slim Jim tools dangerous — they can trigger airbag deployment or destroy wiring harnesses.
