Commercial Locksmith Services for Local Bismarck Properties

commercial locksmith services we provide in Bismarck, ND

We offer many locksmith services for commercial properties, including (top to bottom): door lock installation, lock rekeying, and emergency lockout services.

We support a wide range of local facilities, from single offices to larger sites with many doors. Our goal is to protect access to offices, storage rooms, mechanical spaces, and public entries while keeping use simple for staff and customers.

We also provide standard and high-security key duplication for commercial keys, including Medeco systems for sites that need stronger key control. For supported products, we offer installation and programming services for smart lock hardware, allowing you to use keys and keypads where they best fit your building. Our team explains options in plain language and helps you select hardware that supports your security needs and budget.

Master Key Systems, IC Cores, and Key Control

We handle master key systems for many businesses in and around Bismarck. A master key system allows owners or managers to open multiple doors with one key, while staff use keys that only open their assigned rooms. This structure helps you control access while keeping daily use simple for your team.

We design and maintain master key systems, utilizing interchangeable core (IC core) locks that enable core changes without requiring the replacement of the entire lock. IC cores are useful for buildings with frequent staff or tenant changes because they allow for the replacement of cores and keys with minimal disruption. We create clear key charts, provide key duplication for approved key levels, and explain how to request new keys in the future so your key control stays organized.

Doors, Frames, Closers, and Weatherstripping

Commercial doors experience heavy use and can wear out more quickly than residential doors. Over time, hinges sag, frames shift, and closers lose control. These problems can cause doors to slam, fail to latch, or leave gaps that weaken security and comfort inside the building.

We repair and install doors and frames, including interior and exterior commercial doors. We install continuous hinges for doors that require extra support and adjust or replace door closers to ensure doors close smoothly and latch properly. We also handle weatherstripping and gasketing on commercial doors to help block drafts and extend the life of the hardware.

If your doors drag on the floor, bounce off the frame, or will not close fully, we can inspect the setup and offer clear options. Our goal is to leave you with doors that open, close, and lock in a way your staff can rely on every day.

Break-In Repair and Security Upgrades

A break-in or attempted break-in can damage doors, frames, and locks, and reduce confidence in your building’s security. We provide break-in repair for commercial properties, including lock replacement, frame reinforcement, and hardware upgrades where needed.

We can install stronger lock hardware, continuous hinges, and reinforced strike plates on key doors. For some sites, we may recommend high-security locks and restricted keyways to limit access. You can rest assured that we will take the time to discuss your concerns, examine the damage, and suggest steps that help protect the property going forward.

Smart Locks and Keyless Options for Businesses

Some commercial doors benefit from smart locks or keyless entry options. We install and program supported smart locks for offices and other doors where you want to use codes or electronic credentials while still keeping a key option available.

Smart locks can be useful for staff entrances, small offices, or shared spaces that need easy code changes. We explain what each lock can do, program it for your use, and demonstrate how to make basic adjustments. Due to the local climate, we focus on products that withstand North Dakota conditions while still keeping your doors secure.

Commercial Locksmith FAQ

What is a commercial locksmith?

A commercial locksmith works on locks, keys, and door hardware for businesses and other non-residential properties. We handle office unlocks, lock rekeying, master key systems, door and frame repair, and commercial hardware installation.

Can you unlock our office door if the keys are inside?

Yes. We provide office unlock service for many commercial doors. We use locksmith tools to open the door and can then help with rekeying or key duplication if you want extra keys for staff.

Do you install and maintain master key systems?

Yes. We design, install, and maintain master key systems so managers can use a master key while staff use keys that open only their assigned areas. We also work with IC core systems for properties that need flexible key changes.

How much does commercial lock work cost?

The cost depends on the type of service, the number of doors, and the hardware involved. Rekeying existing locks usually costs less than full replacement or extensive hardware upgrades. Once we know your property details and goals, we provide an estimate before starting work.

Can you rekey our locks so one key can work on several doors?

In many cases, yes. If your commercial locks are compatible, we can rekey them so one key works multiple doors or zones. We match the key plan to your access and security needs.

Do you install and repair door closers and continuous hinges?

Yes. We install and repair door closers and continuous hinges, and we repair or replace doors and frames where needed. This helps doors close and latch correctly and improves long-term security.

Do you offer high-security or restricted keys for businesses?

Yes. We provide high-security key duplication and support for restricted key systems, including Medeco, at sites that require stronger key control and protection against unauthorized key copying.

Do you serve businesses outside Bismarck?

We serve Bismarck, Mandan, Lincoln, and other North Dakota communities, along with part of northern South Dakota, with a main focus on the Bismarck/Mandan area. When you contact us, please share your location, and we will explain how we can assist you.

How do we get started with commercial locksmith service?

You can call our Bismarck storefront or contact us online. Tell us about your building, doors, locks, and current concerns. We will review your needs, answer any questions you may have, and schedule a visit that suits your business.
