Door Lock Types

Locks are installed to maintain safety and security for your business, your personal possessions, and most importantly the people you care about. And what better way to secure your home or office than with a high security lock? The problem is, there are so many different types of locks available, how do you determine the right type of locking system for your building? You can count on the Paragon Security team for expert advice, but here’s an overview of the most popular types of door mechanisms and locks to help you make the best decision.

Padlocks are widely used around the house because they are portable, affordable and easy to install. They consist of a u-shaped shackle that latches two items together. Padlocks either have a key or a combination to open and close them.

Dead Bolt locks are commonly used as an added security feature for both residential and commercial doors. They are activated by turning a spring that puts a bar into a mortise in the door. Dead bolts are made as either single cylinder or double cylinder. Single cylinder requires a key on one side and has a knob for the inside of the door; and double cylinder requires a key on either side.

Dummy Knob locks are used for decorative purposes. They do not have any mechanical latch mechanism, and are only used to pull the door open or push it shut.

Passage Locksets are interior door knobs that cannot be locked from either side, so they are used on closets and pass-through doorways.

Privacy Locksets allow you to lock one side of the door, usually with a push button or small turning knob. They are commonly used in the interior of a home on bedroom or bathroom doors.

Entry Locksets are used inside a home or commercial building. They can only be locked from the outside upon exiting the room.

Surface-mounted Deadbolt locks have most of the mechanism attached to the interior of a door and contain either a vertical or horizontal deadbolt.

Mortise Locks require a hole cut into the door where a bolt or lock is fitted. Dead bolts are examples of mortise locks.

Night Latch doors can be opened from the inside by turning a lever or a knob. The door can be closed simply by pushing it into the frame without having to turn the knob.

Keyless Entry System refers to systems that use electronic locks, which can be activated in various manners such as touchscreens, buttons, and smart keys.

Handlesets are door hardware that have a handle and a button to unlock or unlatch a door instead of a turning knob.

Our Reviews

Trusted Solutions, Exceptional Results
  • 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!”

  • 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”

  • 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!”

  • Very happy with the service
    “I've been using Paragon for more than 20 years. Gal was here most recently to repair several door handles that had become loose. He was knowledgeable, fast and efficient.”

  • 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.”
