What Does a Locksmith Do?
A locksmith is a trained professional who installs, repairs, replaces, and unlocks locks and key systems for homes, vehicles, and businesses. Locksmiths also create new keys, rekey existing locks, program modern car keys, and help restore access during lockouts.
While many people think of locksmiths only during emergencies, their work covers a wide range of everyday security services.

Locksmiths help homeowners maintain and improve their home security systems.
Common residential services include:
