Doors & Frames


Strong, heavy duty doors are an important component of any security system. When they’re not functioning properly, they can become vulnerable to intruders and other security threats. If your storefront or entrance doors are outdated, damaged, or poorly designed, call on Minneapolis Lock & Key. We provide expert commercial door installation for businesses and commercial buildings in Minneapolis, St. Paul, and the surrounding Twin Cities metro area.

If you have one or more commercial doors with only a minor flaw, such as a small gap between the door and frame, we are happy to install weatherstripping or offer other repair services.

Examples of damage and functionality issues we can repair include:

  • Drooping door/frame
  • Bent or broken hinges
  • Outdated/broken hardware
  • Small dents or holes
  • Gaps between door and frame
  • And more!

We work quickly to repair or replace many types of commercial doors, from storefront and fire rated doors to double and retrofit doors. Our experienced security technicians can help you determine whether replacement doors are necessary or if a simple repair will do. Give us a call today at 612-823-8148 to get started!

You may also email us a photo of the door(s) if you wish. One of our technicians will be happy to take a look to determine the best solution. We care about your bottom line and will only recommend a replacement if it is absolutely necessary.


Looking for an advanced commercial door solution? For the most secure protection, Minneapolis Lock & Key supplies and installs steel commercial doors, which are available with or without glass inlays. Not only is steel incredibly durable and long-lasting, but it also offers a sleek, modern appearance that complements any exterior.

Additional benefits of steel commercial doors:

  • Improved Energy Efficiency: Weathered or poorly made commercial doors can not only be a security issue, they can cost you more money in utility bills – especially if the door has an outdated, single-pane glass window. These doors often do not properly shield your structure from the elements, allowing heat or cool air to flow in and out. Upgrade to modern, hollow metal doors and frames for a perfect, weather-tight fit.
  • Minimal Maintenance Required: Steel doors are built to withstand Minnesota’s harshest weather conditions. They won’t crack, warp, or rot, and will continue to look and function great for many years while requiring very little maintenance. Ask your technician for tips on how to keep your commercial doors in tip-top shape.
  • Impact-Resistant: The steel doors we supply are hollow metal – widely recognized as the best value in the commercial door industry. Due to the hollow design, the doors are cost-effective and lightweight for ease of use, yet more impact-resistant than solid steel doors, which can sometimes transfer breaks, cracks, or dents all the way to the edges. Hollow metal doors are much better at absorbing and dispersing impact.

We also offer hollow metal door frame installation, ensuring that you receive a complete and secure solution to your commercial door needs. For more information about the doors and frames, or to request a quote, please contact our team at your convenience.


All of the steel commercial doors supplied by Minneapolis Lock & Key can be customized to suit your needs. We offer new, non-mechanical hardware on the steel doors, including locks, power closers, and continuous hinges.

Electrical/mechanical hardware is also available, such as handicapped door operators. Please contact our team for more information about your hardware options.
