The door needed to be accessible to residents and staff, however also needed to be locked at all times for safety purposes.

Our Reviews

Trusted Solutions, Exceptional Results
  • Highly recommend!
    “We had an emergency when the handle on our living room French doors broke and the doors wouldn't stay closed. We called Paragon, and Michael came over immediately, quickly diagnosed the problem, and spent several hours carefully adjusting the mechanism so the doors worked properly again. Without his help, it could have been a real disaster. We're incredibly grateful for his prompt, kind, smart, and truly professional work - highly recommend!”

  • Neighborhood gem!
    “So convenient and friendly! Needed to get an extra key made today - it was a Mul-T-Lock so a little more complicated. It was incredibly fast and Will at the counter was especially nice and told me about their Tuesday “happy hour” on key cutting - 20% off. Our building uses Paragon for all our building’s keys. They also installed and fixed an electronic keypad for our front door and took the time to do it right. Neighborhood gem!”

  • I have nothing but praise for Paragon
    “I have nothing but praise for Paragon. My apartment intercom handset hasn’t worked for a long time. My neighbor’s handset was replaced by Paragon and she recommended I call. Within a couple of days my inoperative equipment was replaced by a wonderful, timely, considerate young man who explained that the system is soon to be obsolete and I was just in time as the current equipment is not being made. I’m hoping my building considers Paragon to install a new system to bring us into the 21st century. Thank you for your excellent service.”

  • A flawless experience
    “We recently had two camera technicians working in our building Flavio and Adrian, their service was truly outstanding. From the very beginning, they demonstrated a high level of professionalism, punctuality, and technical expertise. They explained each step clearly, worked carefully around the building, and made sure everything was functioning perfectly before finishing. In addition to their excellent work, they were extremely friendly and respectful with all the residents and building staff, which made the experience even better. Their dedication and positive attitude really stood out. Highly recommended for their professionalism and exceptional customer service. A flawless experience”
