Under lock and key 🔒🔑

Meaning

Securely locked away and inaccessible.

Origin

Imagine a time before sophisticated security systems. To keep something truly safe, you'd need a sturdy lock and the corresponding key. This wasn't just about furniture; think about treasury chests, prison cells, or the strongboxes holding valuable documents. The phrase paints a vivid picture: if something is under lock and key, it's not just put away, it's guarded, protected by the dual might of the mechanism and its opener. It signifies a complete absence of access, a state of absolute security intended to deter any prying eyes or sticky fingers.
