Lock repair involves fixing or replacing malfunctioning locks to ensure they operate smoothly and securely. Common issues include broken keys, jammed mechanisms, or worn-out components. Professional locksmiths assess the problem and determine whether a simple repair or a complete replacement is necessary. During the repair process, locksmiths may use various tools to disassemble the lock, clean it, and replace any damaged parts. They can also rekey locks, which changes the internal mechanism so that a new key will work, enhancing security without needing to replace the entire lock. Proper lock repair helps maintain safety in homes and businesses.
