Amazing people & work. My motorcycle key snapped, and out of the 15+ places I called these people were the most helpful. I drove over there with the snapped key, they cut me a new one.

Granite Lock was incredibly responsive when I reached out about rekeying doors in my new home. Zach did a wonderful job explaining what he was doing and making sure I was comfortable with it. He was quick, honest, thorough, and so personable! I'm very pleased with my experience.

Great experience with Granite Lock and Zach was delightful! Being a first time home-owner Zach laid out my options, gave feedback for how to best set up our new locks and provided high-quality service and products. He took time to instruct me in a thorough tutorial on how to use our new lock system. I can rest easy knowing our knew home is safe and functional and know we have a trustworthy company for future needs. Thank you Zach and Granite Lock!

Great service! Zack the locksmith tackled my difficult job. It required waiting for antique parts to be ordered and refitting old parts to work better. It was worth the wait and I was so happy to get this complex job done in a way that kept the look and style similar to the original decor. I would give more then 5 stars if I could.
