What Is a Privacy Function Lock and How Does It Work?

When selecting a lock for a commercial door, the lock function determines how the door can be locked and unlocked and how the inside and outside levers operate.

We previously discussed storeroom locksets and classroom function locks. Another common option is the privacy function lock, which is designed for spaces where temporary privacy is needed.

What Is a Privacy Function Lock?

A privacy function lock is a lockset that can be locked from the inside without using a key.

Privacy locks are commonly used on restrooms, dressing rooms, changing rooms, and other spaces where occupants need temporary privacy.

When the door is locked from the inside, the outside lever becomes inoperable. The inside lever remains operable so the occupant can open the door from inside.

Privacy function locks typically include a means of emergency access from the outside, although the exact operation depends on the lockset.

How Does a Privacy Function Lock Work?

A privacy function allows an occupant to secure the door from the inside while still being able to leave freely.

• Outside lever: Becomes inoperable when the privacy function is engaged from the inside.
• Inside lever: Remains operable and allows the occupant to open the door from inside.
• Inside locking mechanism: Depending on the lock design, a push button, turn button, or similar mechanism is used to lock the outside lever.

           

• Outside emergency access: Privacy function locks typically provide a means of access from the outside in an emergency, although the method varies by lockset.

Operating the inside lever typically releases the privacy function as the occupant exits, although operation can vary depending on the specific lockset.

Privacy Locks with Occupancy Indicators

Some privacy locks are also available with occupancy indicators, which provide a visual indication of whether the room is occupied or vacant.

Occupancy indicators can be found on certain mortise locks and cylindrical locks with privacy indicator trim, as well as on deadbolts with occupancy indicators. Depending on the hardware, the indicator may display wording such as “Occupied” and “Vacant” or use another visual indicator to show the status of the lock.

This feature can be especially useful for restrooms, dressing rooms, changing rooms, and other shared spaces because someone approaching the door can see whether the room is currently in use without trying the door.

Choosing a Privacy Function Lock

A privacy function lock can be a good option for commercial spaces where occupants need temporary privacy without requiring normal keyed access from the outside.

When choosing a lock function, consider who needs to control the door, whether keyed access is necessary, and how the door should operate from both sides. Understanding these differences can help you select the appropriate lock function for your commercial door and application.
