Privacy locks are specialized locks designed to provide security and privacy for interior doors, such as those in bathrooms and bedrooms. Unlike standard locks, privacy locks can be easily engaged from the inside, allowing users to secure the door without needing a key. They typically feature a simple turn mechanism or push-button design. These locks are not meant for exterior doors, as they can often be opened from the outside in case of an emergency. Privacy locks are commonly used in residential settings, hotels, and offices to ensure personal space while maintaining safety and accessibility.
