Question: 1 / 400

What is the function of a pin tumbler lock?

It uses a series of gears

It requires a fingerprint to unlock

It uses a series of pins that must align for the lock to turn

The function of a pin tumbler lock centers around the mechanism where a series of pins must align properly for the lock to turn. In this type of lock, each pin is divided into two parts: a key pin and a driver pin. When the correct key is inserted, the notches on the key lift the key pins to a specific height, aligning them with the shear line of the lock cylinder. Once all pins are aligned correctly, the cylinder can rotate, thereby allowing the lock to open. This design is widely used in many types of locks due to its balance of security and ease of use.

Other options pertain to different locking mechanisms or features that are not characteristic of pin tumbler locks, such as electronic locks that function without pins or locks requiring fingerprints for access. These alternatives represent methods of locking that do not involve the traditional pin and tumbler system.
