Question: 1 / 435

Which component changes the combination in a lock?

Drive Pin

Wheel Pack

Wheel Post

Wheel

The component that changes the combination in a lock is the wheel. In combination locks, particularly those using a rotating mechanism, the wheel is responsible for establishing the correct alignment necessary to unlock the device when the right combination is entered. Each wheel typically has notches or holes that interact with the drive mechanism, allowing for specific positioning based on the combination dialed by the user.

When a person turns the dial to enter a combination, they effectively cause the wheels to rotate into positions that correspond to the set combination. The correct positioning of all wheels then aligns with the drive pin, allowing for the lock to open. Thus, the wheel is a critical element in the combination control process, making it essential to the functionality of the lock. This highlights its role as the component that directly facilitates the changing of the combination.
