I found a set of ALPHA padlocks in the back of the closet. There are 12 of them, and they all use the same key. I couldn't think of many use cases where you'd need multiple padlocks that all open with the same key, but I asked Gemini, and it gave me the following answer: ``` That's a keyed-alike padlock set! Having 12 that all open with the same key makes management super easy. The most common uses are in large facilities, factories, schools, and offices. For warehouses, inspection hatches, lockers, gates, etc., where there are many locking points, you only need one key, so key management isn't complicated. For example, a facility manager can open and close all the warehouses with a single key. It's very efficient because you don't have a jingling key ring! ``` For those managing facilities with many doors that use padlocks, what do you think?
