Lock Change in Washington, DC
Replace commercial door locks in Washington, DC after tenant changes, lost keys, worn hardware, or security concerns.
What's included in Commercial Lock Change
Commercial lock change differs from residential in hardware specification. Commercial doors typically use mortise locks, cylindrical commercial-grade locks, or exit device trim — not the standard residential deadbolts used in homes. Confirming the door preparation — bore size, backset, door thickness, and whether the current hardware is cylindrical or mortise — before the visit ensures the correct replacement hardware is on the truck. For multi-door office suites, a master key system can be built into the new hardware at the time of installation.
We provide all necessary hardware, ranging from standard Schlage C keyways to restricted high-security systems. Every installation includes a functionality test to ensure the latch engages properly and the door meets local Washington, DC egress requirements.
- Installation of grade 1 heavy-duty commercial cylinders and housings.
- Replacement of mortise locks, rim cylinders, and deadlatches.
- Setup of SFIC (Small Format Interchangeable Core) systems by Best or Falcon.
- Narrow stile storefront lock replacements (Adams Rite specialists).
- Testing and adjustment of door closers and strikes for perfect alignment.
When you need Commercial Lock Change
Business owners often wait until a lock fails completely before calling for service, but proactive replacement is key to maintaining security and avoiding emergency lockout situations. If you notice your key turning with difficulty or the handle sagging, the internal springs and pins are likely worn beyond repair.
Another critical scenario is a change in management or staff. While rekeying is an option, a full commercial lock change allows you to upgrade to modern hardware, such as the Schlage L series or Sargent mortise locks, which offer superior durability and drill resistance compared to older models.
- Following a urgent security concern or unauthorized entry into your facility.
- When taking over a new commercial lease or office space in DC.
- If your current hardware is sticking, grinding, or failing to latch.
- After a high-level employee departure where keys were not returned.
- To upgrade from standard keys to a more secure, pick-resistant system.
Our process for Commercial Lock Change
Our process begins the moment you call (202) 559-7070. We arrive at your Washington, DC location in a fully equipped mobile lab, ready to handle any door configuration. We don't just "drop in" a lock; we ensure the backset is correct and the cylinder is timed perfectly with the bolt mechanism.
For businesses with specialized requirements, such as panic bars or narrow stile aluminum doors, we use specialized tools to ensure the fit is exact. We handle the entire cleanup and provide you with a full set of new keys, ensuring your business is secure before we leave the site.
- On-site assessment of your door type (hollow metal, glass, or wood).

Pricing & what affects cost
Transparency is the cornerstone of our service at DC Mobile Locksmith. The cost of a commercial lock change varies based on the level of security your business requires. A standard storefront cylinder replacement is more affordable than a full-scale Schlage mortise lock installation, which involves complex internal mechanics.
We provide honest, upfront pricing once we see the hardware in person. While high-security brands like Medeco or Mul-T-Lock carry a higher initial investment, they save DC business owners money in the long run through increased durability and key control. Give us a call for a clear estimate tailored to your specific hardware needs.
- The grade of hardware selected (Grade 1 vs. Grade 2).
- The complexity of the lock (Mortise locks vs. cylindrical levers).
- Modifications required for the door or frame to fit new hardware.
- The number of locks being changed across the facility.

Frequently asked questions
How long does it take to change a commercial lock?
In most cases, we can complete a standard commercial lock change in 30 to 60 minutes per door. Mortise locks or complex exit devices may take longer, but our fully stocked vans ensure we rarely need a second trip.
Can you upgrade my old storefront locks to something more secure?
Yes. We specialize in retrofitting old commercial doors with modern, high-security hardware. Whether you are upgrading to an Adams Rite deadlatch or a heavy-duty Schlage L series mortise lock, we ensure the new hardware fits perfectly and functions smoothly.
Do you offer interchangeable core (IC) cylinders for quick turnover?
Absolutely. We can install SFIC (Small Format Interchangeable Core) systems from brands like Best or Falcon. This allows you to change the 'core' of the lock in seconds without tools, providing instant security after employee turnover.
Is it better to rekey or change the entire lock?
Rekeying changes the internal pins so a new key works, while a lock change replaces the entire physical chassis. We recommend a full change if the hardware is worn, damaged, or no longer meets DC fire and life safety codes.
Will my new locks be compliant with DC fire codes and the ADA?
Yes. All commercial lock changes we perform in Washington, DC are done with ADA requirements and local fire codes in mind. We ensure your new hardware features the correct lever handles and 'single-motion' exit functionality required by law.
