DO NOT USE. We used this company about five months ago. The lock was never put in correctly and the doorknob was loose the entire time. We questioned it, we were told that this is how it had to be. We were charged some exorbitant amount of money. The lock was clearly never put in properly. It's now a few months later, and the cylinder with lock has completely fallen out of the door. The company refuses to take responsibility and I cannot get them to send someone to fix it.
I'm not sure this is a real company. I think it's just a bunch of guys who say they are locksmiths that get called through a computer application. There is no one there that actually guarantees the work much less takes responsibility for it. There are many other locksmiths in NYC. Use someone else.
