The key stop and the #1 space position for an IC (Interchangeable Core) key are found at the tip of the key. This positioning is essential because the tip of the key is where it makes initial contact with the locking mechanism when the key is inserted into the cylinder. The #1 space refers to the cut on the key that corresponds to the first cut depth defined by the lock's specifications. This ensures that the key can properly align with the pin tumblers in the lock for it to function correctly.

Understanding the layout of an IC key is crucial for locksmiths, as it helps them recognize the specific points of engagement between the key and the lock, as well as the importance of proper key cuts and depths to ensure security mechanisms operate as intended. Positioning at the tip also allows for a consistent engagement with the locking mechanism across different types of locks that use IC systems.
