Not all locks are equal. The $30 deadbolt from a hardware store is built differently than what a locksmith installs on a commercial building — and the difference shows up when it's tested by an intruder, a fire, or just daily use. Here's a practical guide to choosing the right commercial locks for your Charlotte small business, based on what we actually install and recommend every day.
ANSI/BHMA Lock Grades Explained
Every commercial door lock sold in the United States is tested and rated under ANSI/BHMA standards. There are three grades, and the differences are significant:
The rule is simple: any exterior door on a commercial building should have Grade 1 hardware. Interior doors can sometimes use Grade 2 depending on the application, but Grade 1 is always the better investment for doors that matter — server rooms, offices with sensitive information, stockrooms with high-value inventory.
Types of Commercial Locks
There isn't one lock that fits every application. Here are the six main types you'll encounter on commercial properties in Charlotte, and where each one belongs:
Top Commercial Lock Brands — What We Install in Charlotte
Not all brands are equal, and your choice of brand affects not just initial security but long-term serviceability, parts availability, and key control. Here's an honest look at the brands we regularly install for Charlotte businesses:
Schlage (B-series commercial) — The most common Grade 1 commercial deadbolt in Charlotte. Excellent build quality, widely available for service, and good value for the security provided. The Schlage B60N and B62N are workhorses we install constantly on commercial back doors, offices, and secondary entries.
Medeco — High-security locks with patented key control. Medeco cylinders are pick-resistant, drill-resistant, and use a restricted key system that prevents unauthorized duplication at hardware stores. If you handle sensitive data, pharmaceuticals, financial records, or valuable merchandise, Medeco is worth the premium.
Mul-T-Lock — Israeli-engineered with telescoping pins that provide exceptional pick resistance. Like Medeco, Mul-T-Lock uses a patented restricted keyway — keys can only be duplicated with authorization. Excellent choice for businesses with high employee turnover or any situation where key control is a priority.
Adams Rite — The industry standard for aluminum storefront glass doors in Charlotte and nationally. If you have a glass-front retail or office unit in a strip mall, your door almost certainly has an Adams Rite rim cylinder and deadlatch. We stock Adams Rite parts and can repair or replace on the first visit.
Corbin Russwin — A go-to brand in healthcare, education, and institutional commercial buildings. Heavy-duty cylindrical and mortise hardware with excellent durability for high-traffic doors. Common in medical offices, dental practices, and multi-tenant professional buildings throughout the Charlotte metro.
Kaba / dormakaba — Commercial lever hardware with a strong ADA compliance focus. dormakaba (formed from the merger of Kaba and Dorma) makes excellent commercial lever sets used in offices and medical facilities throughout the Southeast. Also a major player in electronic access control hardware.

What Locks Does My Business Actually Need?
The right hardware depends on the door, the risk level, and the daily usage. Here's a straightforward breakdown by door type for Charlotte small businesses:
- Front door (primary entry): Grade 1 deadbolt + Grade 1 knob/lever, or a mortise lock if you want a single heavy-duty unit that handles everything. The deadbolt is non-negotiable on any exterior door.
- Back door / delivery entrance: Grade 1 deadbolt at minimum. These doors are often targeted because they're less visible from the street — don't cut corners here.
- Interior office or server room: Grade 1 lever (ANSI A156.2 Grade 1). Server rooms and offices with financial records or sensitive data deserve the same level of hardware as exterior doors.
- Glass storefront: Adams Rite deadlatch + rim cylinder. This is the standard setup for retail units in Charlotte strip malls and commercial plazas. Make sure the cylinder hasn't been worn down over years of use.
- Storage room / warehouse: High-security padlock (Abloy, Medeco, or Mul-T-Lock) with a shrouded shackle on a properly reinforced hasp. The lock is only as strong as what it's mounted on.

Security professionals talk about "key control" — and it's something most small business owners don't think about until it costs them. Here's the core issue: a standard lock can be rekeyed when an employee leaves, but if the old keys are still out there, those keys can be copied at any hardware store before you get around to rekeying.
There are three ways to address this:
- Rekey immediately on any staff change. Don't wait. The cost of rekeying one door is minimal compared to a break-in. Our rekey service is fast and affordable for Charlotte businesses.
- Use a restricted keyway. Locks from Medeco and Mul-T-Lock use patented key blanks that hardware stores don't stock. Duplicating those keys requires authorization through the manufacturer's authorized dealer network — which is us. This is the most effective form of physical key control.
- Switch to access control. If you have significant staff turnover or a large number of key holders, consider eliminating physical keys entirely. A keypad or card-based system lets you revoke access in seconds, no locksmith visit required. See our access control page for options.
If you're running a master key system, key control becomes even more critical — a compromised master key gives access to every door in the hierarchy. We design master key systems with key control as a primary consideration.
When to Upgrade Your Locks
Not every business needs to replace locks immediately — but these situations are clear indicators that an upgrade is overdue:
- Moving into a new commercial space. You have no idea how many keys the previous tenant made or distributed.
- After a break-in attempt, even an unsuccessful one. A forced entry attempt often damages the lock mechanism in ways that aren't immediately obvious.
- If locks are 10 or more years old. Commercial lock cylinders wear out. Worn pins and drivers make locks easier to pick and more likely to fail on you.
- When you want to add a master key system and the existing hardware isn't compatible with your chosen key system.
- After a significant staff change, especially the departure of someone with wide key access.
