What is double lock in hotel?

I’m trying to learn about hotel lock systems and security, so I have a question: What is a double lock in a hotel?

In the hotel industry, the term “double lock” or “double locked door” can refer to a couple of different things, depending on the context:

Guest Room Security: Most hotel room doors have two locking mechanisms for added security:
- The primary lock is the regular lock that engages when the door is closed or when a key or card is used.
- A secondary lock can be a deadbolt, security chain, or swing bar lock. This secondary lock can only be engaged from inside the room and provides an additional layer of security for guests. Even someone with a key or access card (like hotel staff) cannot enter the room when this secondary lock is engaged.
Hotel Management System: In the context of hotel management and room status, “double lock” or “double-locked” can refer to a room status indicating that a guest has locked the room from the inside, implying that the guest is currently in the room. This status is important for housekeeping and other hotel staff to know, as they typically won’t enter a room that’s double locked without explicit permission or a very good reason.

In both contexts, the idea behind the “double lock” is to provide hotel guests with security and privacy. If you’re ever unsure about a hotel’s locks or security features, it’s always a good idea to ask the hotel staff or check the room’s information booklet.
