Question: 1 / 400

In locksmithing, what are "lands"?

Grooves on the keyway

Highest, widest, or thickest portion of a key or keyway

In locksmithing, "lands" refer to the highest, widest, or thickest portions of a key or keyway. This term is significant because the lands are crucial for the proper functioning of a key within a lock mechanism. They play a key role in ensuring that the key fits correctly into the lock, allowing for smooth operation and engagement with the lock’s internal components.

When a key is manufactured, the lands must be designed precisely to match the specifications of the lock to ensure that when the key is inserted, it can align with the lock's pins or tumblers accurately. Understanding the concept of lands helps locksmiths in key cutting, lock picking, and troubleshooting locking mechanisms.
