Automotive Locksmithing Tools Flashcards

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

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.

A laser key cutter (also called a sidewinder cutter) is specifically designed to cut which type of automotive key profile?

Answer: High-security laser/milled track keys

Laser key cutters are designed to cut high-security laser-cut (milled/sidewinder) keys that have cuts machined into the side rather than the edge of the blade.

When using a code cutting machine, what is the 'bitting list' used for?

Answer: Identifying the sequence and depth values for each key cut based on the key code

A bitting list (or bitting code) provides the specific depth values for each cut position on a key, allowing the code cutter to produce the correct key from the key code alone.

Which tool is specifically used to extract a broken key fragment that has snapped off inside an automotive door lock cylinder?

Answer: Key extractor

Key extractors are hooked or barbed tools inserted alongside a broken key fragment to grip and remove it from the lock cylinder without damaging the cylinder.

A 'tryout key set' for automotive locksmithing is used to:

Answer: Progressively try many pre-cut keys to open a lock without the original key

Tryout key sets contain a series of keys with different bitting combinations that are tried systematically in a lock to find the correct combination without the original key.

What is the function of a 'clamp' or 'jaw' on a key cutting machine?

Answer: It holds the key blank securely in the correct orientation during cutting

The clamp or jaw on a key cutting machine firmly holds the key blank in the proper position and orientation so that cuts are made accurately at the correct locations.
