About Us
Our company started out in 2006 as a local locksmith providing mostly house/vehicle lockout, key duplication, and lock repairs in Baltimore MD. We quickly turned into a full service locksmith and security company due to huge need in Baltimore & central Maryland for a reliable and licensed locksmith and security systems company.
All of our locksmiths go through an extensive training to ensure they are experts at not only lockouts but also all other facets of locksmith service. Our shop on Reisterstown Rd near Pikesville in Baltimore MD and our locksmith shop in Timonium MD offer a variety of safes, locks, keys, cameras and many other security products for sale.
At these Baltimore locations we offer comprehensive lock, key, and safe services including key copying, rekeying of locks, master keying of locks, car key replacement for almost all cars and car key fob programming.
We also have an express locksmith shop in Downtown Baltimore on Baltimore St for house key duplication and a safe & vault shop in Middle River. Our Downtown Baltimore location does not provide the extensive locksmith work on-site like our other 2 Baltimore locations.
Please call us so we can direct you to the right Baltimore location for your specific needs or dispatch out a mobile locksmith unit to you anywhere in Baltimore-Columbia-Towson Metropolitan Area.
