Customer Testimonials

Without at doubt 5 STARS. I wish I could give them 100! I own a hair salon and needed our lock for our front door changed. I e-mailed them in the morning, they gave me quick reply. Jeff came at 4pm as said, and changed our lock in 10 minutes. Great price, great service, and simply just a great guy. Thank you so much, you saved our day.

I left my keys in my bedroom and found myself locked out. I called and had someone get here within 15 minutes! And It was a holiday! The guy who helped me out was extremely friendly and got me in even faster than he got here! Great service!

They put a new programmable lock on front door at my house. I love the new system that Hks System suggest that I go with for safety. They do a great job at the apartment complex that I manage and always show up on time. I always get great service from the company.

Great service! Called in for a rekey 30 mins before the guy arrived! Great guy and quickly serviced. I'm very impressed. Will use them again.
