CPL Key Cutting & Code Origination 3

Question 1

What is the purpose of a 'spacing gauge' when originating keys by code?

Accepted Answer

To determine the correct horizontal distance between cuts on the key blade

Answer

A spacing gauge ensures each cut is positioned at the correct horizontal distance from the reference point along the key blade.

Question 2

The 'MACS' (Maximum Adjacent Cut Specification) rule prevents:

Accepted Answer

Bitting combinations where adjacent cuts differ by too many depth increments, making a key inoperable

Answer

MACS limits how much adjacent cuts can differ in depth to ensure a key can physically operate a lock without binding the tumblers.

Question 3

Which type of code book would a locksmith use to find the key cuts needed for a specific lock serial number?

Accepted Answer

An indirect code book that translates serial/code numbers to bitting depths

Answer

An indirect code book translates a lock's serial or code number into the actual cut depths needed to originate the key.

Question 4

On a code-cutting machine, the 'index' positions represent:

Accepted Answer

The fixed spacing stops that position the key blank for each successive cut

Answer

Index positions on a code-cutting machine are precisely spaced stops that advance the key blank to the correct position for each cut.

Question 5

A locksmith originating a Ford automobile key from a code uses cuts measured in what unit?

Accepted Answer

Arbitrary depth numbers (1–6 or 1–8)

Answer

Automotive key systems, including Ford, typically use arbitrary depth designations (such as 1–8) that correspond to specific physical depths defined in the manufacturer's specifications.
