North Carolina Locksmith Practice Exam

The use of a key extractor is specifically designed for the purpose of removing a broken or stuck key from a lock. This tool typically features a set of fine, pointed hooks or jaws that can grip onto the part of the key that is lodged inside the lock. By carefully inserting the extractor into the lock alongside the broken key, a locksmith can manipulate it to catch and pull out the remnants of the key without damaging the lock itself.

In contrast, the other tools listed are not suited for this particular task. A lock pick is intended for manipulating the lock's internal mechanisms to open it without a key, not for extracting keys. A wrench is primarily used for turning or gripping objects but would not effectively remove a broken key from a lock. The torque tool is designed to apply rotational force and is irrelevant in the context of key extraction, as it does not assist in extracting items lodged within a lock. Therefore, the key extractor is the most appropriate and effective tool for addressing this specific locksmithing challenge.
