Locksmith Test #6

Question 1

The only available outlets are 2-pronged, however a power tool has a 3-pronged connector. What is the technician supposed to do?

Accepted Answer

Locate a 3-pronged outlet

Answer

The third prong on a power tool's connector is a ground wire, a critical safety feature designed to protect the user from electrical shock. Removing it or using an adapter that defeats the ground connection is extremely dangerous and violates electrical safety standards. The only safe and proper solution is to use a properly grounded 3-pronged outlet.

Question 2

Please explain how to properly utilize security pins with a mushroom and spool:

Accepted Answer

They make standard lock picking attempts more difficult

Answer

Security pins like mushroom and spool pins are designed with irregular shapes (e.g., tapered, undercut, or spooled) that create false sets during picking. When a picker encounters a false set, it feels like a pin has been set, but it's actually binding in a way that prevents the lock from opening, making it much harder to determine the true shear line and successfully pick the lock.

Question 3

GM 10-cut lock mechanism often denotes the following in the lock:

Accepted Answer

An even number of total cut depths

Answer

Some GM 10-cut lock mechanisms are designed with a specific keying system where the sum of the bitting depths across all cuts, or specific pairs of cuts, results in an even number. This characteristic is often part of their master keying or interchangeability systems, ensuring compatibility and functionality within their automotive lock designs.

Question 4

How many trainees can an experienced technician supervise on a given job site?

Accepted Answer

3

Answer

While specific regulations can vary by jurisdiction and industry, a common guideline or best practice in many trades, including locksmithing, suggests that an experienced technician can effectively supervise up to three trainees on a job site. This ratio allows for adequate instruction, direct oversight, and ensures safety and quality of work without overwhelming the supervisor.

Question 5

Please specify the kind of lock that the sentence refers to: a key-in-knob lock that requires a key on each side to open.

Accepted Answer

An asylum or Institutional Lock function

Answer

An asylum or institutional lock function is characterized by requiring a key on both sides to open the door, meaning there is no free egress or entry without a key. This type of lock is specifically designed for environments where strict control over movement is necessary, such as psychiatric facilities or correctional institutions, to prevent unauthorized entry or exit.
