Operating inside lever, closing door or operating outside emergency release unlocks outside lever. Latch bolt operated by lever from either side except when outside lever is locked by inside turn or button. Some privacy functions may also incorporate an indicator to show the locked/unlocked status of the lock. There are several variations on this function, including a hospital privacy which has a thumbturn on both the inside and outside to allow hospital staff quick access to the bathroom. They can be locked from the inside with a thumbturn or push button/turn for privacy, and they are typically unlocked from the outside using a tool rather than a key. Privacy sets are used for restrooms or dressing rooms.
Latch bolt operated by lever from either side at all times. There is no key cylinder and no means to lock a passage set. Passage sets are used where doors do not need to lock.

Please note that all of these functions allow free egress at all times. The most common functions for mechanical locks are described below. Add in a few deadbolt functions, and a basic understanding of electromechanical locks, and you’ve got the most common lock functions mastered! If a project requires a different lock function, our spec writers can help you decide which one to use. Luckily, there are 6 mechanical lock functions that account for the vast majority of locks specified. In fact, when I was teaching our spec writer apprentices a few weeks ago I said, “Don’t ask the architect if he or she wants a storeroom function lock, ask if the door should always require a key to enter.” A manufacturer’s catalog may show 50 different lock functions (or more!) and it’s difficult or impossible to remember how each function works. The topic of lock functions seems to arise at almost all of those meetings–usually someone in the room needs a refresher on how the basic functions work.
Back-to-basics: Lock functions When a hardware consultant writes a specification, it’s common practice to sit down and discuss the project with the architect, at least for the more complicated jobs.
