Read the first 7 Key Cutting & Code Origination flashcards as text

  1. Which method of key origination involves using a code derived from the lock's serial number stamped on its face?

    Answer: Code origination from factory code

    Code origination from a factory code uses the serial or code number stamped on the lock or hardware to look up and cut the correct key.

  2. A 'key blank cross-reference' is primarily used to:

    Answer: Identify alternate manufacturer blanks that fit the same keyway as a given original blank

    A cross-reference guide identifies compatible aftermarket or alternate brand blanks that share the same keyway profile as a specific original blank.

  3. What is the purpose of the 'tracer' on a manual key duplicating machine?

    Answer: To follow the original key's cuts and guide the cutter to reproduce the same pattern

    The tracer (or stylus) follows the profile of the original key, mechanically guiding the cutter to reproduce identical cuts on the new blank.

  4. In a high-security key system, 'restricted keyways' serve what purpose in code origination?

    Answer: They prevent unauthorized duplication by controlling access to the key blanks

    Restricted keyways use proprietary blank profiles that are only available to authorized dealers, preventing unauthorized key origination.

  5. When originating a key from an indirect automotive code, the code '1234' represents:

    Answer: A translated code that must be looked up in a code book to find actual bitting depths

    Indirect codes are reference numbers that must be translated through a manufacturer's code book to determine the actual cut depths.

  6. What is the significance of 'first cut distance' (also called 'stop distance') in key cutting?

    Answer: It specifies the distance from the key's reference point to the center of the first cut

    The first cut distance (stop distance) positions the first bitting cut at the correct location from the reference point so all subsequent cuts align with their corresponding tumblers.

  7. A locksmith discovers that a key cut to code does not operate the lock smoothly. The FIRST diagnostic step should be:

    Answer: Verify the correct code book section and key blank were used before re-cutting

    Verifying the correct code section and blank confirms whether a lookup or blank selection error occurred before any re-cutting is attempted.
