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.

No wonder they’re so highly rated. I “had a lot going on” as Zach said. He couldn’t have been nicer getting me sorted out. I was expecting a nightmare but he just took care of everything.

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!
