DC Commercial Door Solutions installs and upgrades high-security commercial lock systems for businesses and property owners throughout Washington, DC. High-security locks use restricted keyways and commercial-grade cylinders that are harder to duplicate or bypass than standard commercial locks, and they’re often paired with formal key control policies.

High-Security Lock Features

  • Restricted keyways — keys can’t be duplicated without authorization
  • Commercial-grade cylinders built for higher-traffic, higher-security applications
  • Key control tracking for who holds which keys
  • Compatibility with existing commercial door hardware in most cases

For restricted keyways and pick- and drill-resistant cylinders, we install and service Medeco and Mul-T-Lock high-security cylinders and locks, including retrofitting them into existing mortise, rim and cylindrical hardware at offices, retail spaces and government facilities in Washington, DC.

Upgrading Existing Locks

Many businesses upgrade to high-security locks without replacing their existing doors or frames — the lock hardware itself is what changes. We evaluate your current hardware to confirm compatibility before recommending an upgrade.

Integration with Door Hardware

High-security cylinders are often integrated into existing mortise or cylindrical lock bodies, and can be combined with electrified hardware for access-controlled doors — see our access control and commercial door hardware pages for related integration options.

When High-Security Locks Make Sense

Not every door needs high-security locks, but some openings carry more risk than others. Businesses usually upgrade when:

  • Keys have been copied without permission, or no one is sure how many copies exist
  • A door protects cash, inventory, records, controlled items, or server and utility rooms
  • A building has many tenants or contractors and needs tighter key control
  • An insurer, landlord, or internal security policy calls for restricted keys
  • A break-in or attempted break-in exposed a weak cylinder

How Restricted Keys Work

With a restricted key system, key blanks are not sold to the general public, so a key cannot simply be duplicated at a hardware store or kiosk. Additional keys are cut only for people you have authorized, which gives you a reliable record of how many keys exist and who holds them. For many businesses this key control is the main reason to move to high-security locks, more than the added physical resistance. If a key is lost or an employee leaves without returning one, the affected cylinders can be rekeyed without replacing the locks.

Our Installation Process

We start by reviewing which doors need the upgrade and how keys should be organized. In many cases the existing lock body can stay and only the cylinder is changed, which keeps cost down. Where the lock itself is worn or light-duty, we replace it with commercial-grade hardware. Every cylinder is tested with its keys, and you receive the keys along with a record of the key system. High-security cylinders can also be combined with a master key system, so managers carry one key while staff keys open only their own doors.

Frequently Asked Questions

What makes a lock “high-security”?

Restricted keyways that prevent unauthorized key duplication, along with commercial-grade cylinders built for higher-security applications.

Can high-security cylinders be added to existing locks?

In many cases, yes — high-security cylinders can often be integrated into existing mortise or cylindrical lock bodies.

Does upgrading to high-security locks require a new door?

No, in most cases only the lock hardware changes, not the door or frame.

Can high-security locks be integrated with access control?

Yes, high-security cylinders can be combined with electrified hardware for access-controlled doors.

Are high-security locks pick- and drill-resistant?

High-security cylinders are built to resist picking and drilling far better than standard cylinders, and their keys use restricted keyways so copies need authorization. No lock is impossible to defeat, but they raise the difficulty considerably.
