Granite Lock Co
About Us

Granite Lock Co., Inc. is a family-owned and operated business serving the South Shore and neighboring communities. Located in the City of Presidents and the city known for its granite quarries, our locksmithing roots date back to 1958 where Dick began his locksmithing career at Granite City Hardware. Granite Lock opened its doors in 1981 when his son, Rick, joined him. From that point forward, we have expanded our business to now include additional service technicians along with a third generation apprentice. We are constantly striving to keep up with all the current technologies from cutting of keys, programming transponder keys, modern mechanical and electronic locking systems and much more. Granite Lock is your complete locksmith providing personal, professional service. We are a diversified locksmith here to help you solve your security needs.
