I can’t thank Chris enough for his professionalism, skill, and compassion. I recently needed help unlocking a safe that belonged to my late father, and it was a very emotional task for me. Chris handled the situation with such respect and understanding from the moment I arrived. He worked carefully and efficiently, explaining each step and making sure the safe was opened. What truly stood out was his kindness—he understood how meaningful this was to me and treated the entire process with genuine care. It’s rare to find someone who combines technical expertise with such empathy. I’m so grateful for Chris’s help and would highly recommend Granite Lock to anyone in need of a trustworthy and professional locksmith.

I can't recommend them enough. I emailed them with my questions and they got right back to me. Zack was incredible, very friendly, extremely knowledgeable and went above and beyond. He did such a great job, we had him come back a 2nd time to replace the handles and locks on our other doors. Def give Zack a call if you need any work done. He's the best.

Very responsive, fast reliable work! I called up to have 6 cylinders re-keyed and in under 48 hours the work was done! Really great experience working with Zack, I will be going back to Granite for all future needs.

Chris was amazing and honest. He was able to help us with our issue. We were left a safe that had no key. He was able to open it. He also verified our relationship to the owner of the safe. Definitely would recommend

I have a very old house, built in 1910. I called Granite Lock with an issue with the front door. I thought I might have to get a deadbolt and drill into the woodwork of the door. Granite lock sent out their technician, Zack, within a day. Zack was extremely knowledgeable and explained the necessary repair. Also … he didn’t just push me to the most expensive option as he said the old lock was good and solid and just needed some repair in the mechanism. He was quick and thorough and did an excellent job!! I will always choose Granite Lock. They are reliable and trustworthy.
