I have taken my lock problem to this small company since I was a teenager, for the past 35 years. I use safes (Sargent and Greenleaf), Medico, Abloy, and other high end and garden variety Schlage and Kwickset locks. Then there are my old and new cars. When I lived in other states, I was never able to find a decent locksmith. These guys at Santa Monica lock and Safe are far and away the best locksmith I have ever used, or ever heard of. They completely know their stuff. Their craftsmanship is unmatched. If you leave them to install new locks on your building, when you come look later you will see no sawdust is left lying around, all doors engage perfectly, it could not be done better. Plus, they are very inexpensive, very honest, reliable, and I think pretty much always undercharge me. Highly recommended!
