Question: 1 / 400

Which component is NOT part of a key duplicating machine?

Key guide

Cutting wheel

Lock cylinder

The lock cylinder is not a component of a key duplicating machine because its primary function is to house the mechanism that allows a key to engage and operate a lock. In contrast, a key duplicating machine is specifically designed to replicate keys and does not require the actual lock cylinder for the duplication process.

A key duplicating machine typically includes a key guide, which assists in properly aligning the key to be copied; a cutting wheel, which precisely cuts the new key to match the original; and vise jaws, which securely hold the key in place during the duplication process. Understanding these components highlights their roles in ensuring accurate and efficient key duplication, while the lock cylinder’s function pertains solely to locking mechanisms, making it irrelevant in the context of key duplication machinery.
