I would love to give ZERO stars! We called as the lock to the front door of our building was broken and we had Mathias come out to look. About a week later we received an estimate for $160.00. $75 for the work and $85 for the TRIP charge. They charge more to come out than they do for the work. I found a MUCH better place with VERY reasonable prices

I've rekeyed all my own locks for over 25 years. Mathias has been my sole source for keys and, occasional, advice. I've never had an incorrectly cut key. They are a great resource when one needs security that exceeds standard, consumer-grade locks. Consistently responsive & professional.

My favorite locksmith and I've used a many! I frequently have to cut keys and have locks re-keyed for work and have been doing so for several years. The techs are reliable, accurate and efficient. The accounting department is even friendly and efficient. The staff is consistent, responsive and clearly enjoy their job. I see very little turnover so I always get to see my faves Steve and David!

SHOUT OUT to Mable and Blake! Mable so friendly to get me where I needed to go. Blake, who we'd not seen two years or more, remembered our set up and was quick to know what needed to be done. Made us his first call and arrived in no time. Got our system fixed in less than ten minutes. CANNOT ask for better service! THANK YOU!
