A "Key Opener" is a tool designed to assist in opening various types of locks, particularly those that use traditional keys. It often features a simple design that allows users to manipulate the lock mechanism without damaging it. Key openers can be useful for locksmiths, security professionals, or individuals who may have lost their keys. In addition to physical key openers, the term can also refer to software tools that help unlock digital files or systems. These digital key openers are often used in cybersecurity to recover access to encrypted data, ensuring that users can regain control of their information when needed.
