I originally contacted this company because I was desperately trying to figure out how our condo board would get access to make Mul-T-Lock keys. The prior board had passed them out, and the new board had no idea where the key code was to copy more once a tenant lost both of her keys. After contacting at least 20 to 30 different locksmiths, plus Mul-T-Lock headquarters explaining our hands were tied (and finding out later that one locksmith who claimed they didn't copy our keys really WAS the company that did), Nonstop Locksmith was the only one that would allow me to prove that we were legit. With paperwork in hand to confirm we were legitimate board members, they were able to copy our key and also contacted the headquarters, too. (Shortly after, our incompetent and terminated property management company said they "didn't know what that box was for with the code on it" but never bothered to mail it to us or even tell us they still had it. So we finally did get the box after I had to track down that property manager plus the one before that.) Alexander was the locksmith I worked with, and he was EXTREMELY professional, helpful and funny, too. When I found out that they fixed doorbells and their rates were decent, I contacted them again. The one in my building had terrible audio, and other owners had doorbells that didn't work either. I was elated to do business with them. While I could go through all the details of them having to visit five different times due to rewiring, two condo owners who refused to stay home (or answer their door), weather damage in two bells and station replacements, what I will say is I grew extremely frustrated. But through it all, with one technician (Manuel), one manager (David) and one field manager (Rodney), we were finally able to get two of three doorbells in operable condition. The last one still has wiring issues, but that has zip zero to do with Nonstop Locksmith and everything to do with residents refusing to let them in to replace the wires. Rodney especially was patient, professional and did try to explain what the problems were. Although I did leave with more questions than answers with Manuel and David during the first few visits, physically standing there and watching Rodney work and listening to them cleared up a lot of confusion versus a summary at the end of hours of work. In all fairness, David did give me a chart to show his progress. Still, I'm a big fan of not hounding contractors while they work, but I finally did realize that wasn't going to work in this case and decided to stay put and just quietly observe. Shimon, the owner, stepped up to try to get all of our doorbell problems resolved, too, and called three times, too. While I certainly wish we could've been a one-and-done, in an older building with wiring issues that happened long before I moved in, this turned out to be a much bigger job than I expected. But I am relieved that it is (mostly) done and totally done to the best of their capabilities. Thank you!
