North Carolina Locksmith Practice Exam

Question: 1 / 435

Identify the type of key that features a tubular blade with cuts made around its circumference.

Tubular Key

A tubular key is designed with a cylindrical shaft and a blade that is shaped like a tube. The distinct feature of this key is that it has cuts or grooves made along the circumference of its circular blade. These grooves correspond to the pins located inside a tubular lock cylinder. When the key is inserted into the lock, the cuts align with the pins, allowing the lock to turn and open.

This design offers several advantages, such as increased security and complexity, making it more difficult to pick than traditional flat keys. Tubular keys are commonly used in various applications, including vending machines, computer locks, and some bicycle locks, due to their unique shape and function.
