Key extractors are tools used in locksmithing and security to remove broken keys from locks. They typically feature a thin, flexible design that allows them to fit into tight spaces within a lock. By carefully maneuvering the extractor, a locksmith can grasp the broken key fragment and pull it out without damaging the lock itself. These tools come in various shapes and sizes, often made from durable materials like stainless steel. Key extractors are essential for maintaining the functionality of locks, ensuring that users can regain access without the need for complete lock replacement.
