Question 2

Which part of a key blank determines compatibility with a specific lock brand and model?

Question 3

On a standard key cutting machine, what component holds the key blank in place during cutting?

Accepted Answer

The carriage clamp (vise)

The carriage clamp (vise) secures both the original key and the blank so they move together while the cutter and tracer follow the bitting pattern.

What is the 'shoulder' of a key used for when cutting on a manual key machine?

Accepted Answer

It is the reference stop point that aligns the key's cuts to the correct position
