What's included in Residential Lock Change

Lock change versus rekey is a decision based on the condition of the hardware. Rekeying is the right call when the deadbolt is mechanically sound but the key access needs resetting. Lock replacement is necessary when the deadbolt is worn, corroded, misaligned, or below the security level you want. For DC rowhouses with original hardware, upgrading from a builder-grade deadbolt to a Grade-1 deadbolt is a straightforward same-day job that significantly improves door security.

We provide a wide inventory of finishes—from satin nickel to oil-rubbed bronze—so your new high-security hardware matches your home’s aesthetic. Our goal is to blend superior mechanical strength with the visual appeal your DC home deserves.

Installation of ANSI Grade 1 and Grade 2 deadbolts and lever sets.
Expert replacement of mortise lock cylinders and rim cylinders.
Upgrading standard locks to high-security brands like Medeco, Mul-T-Lock, or Schlage.
Smart lock integration including keypad and biometric entry systems.
Reinforcement of strike plates and door frames for added kick-in protection.
Precision key cutting for all newly installed hardware on-site.

Security needs evolve over time. If your locks are over a decade old, the internal components have likely worn down, making them easier to bypass. A Residential Lock Change is often the most cost-effective way to reset your home's security perimeter.

For many Washington, DC residents, the transition between tenants or the purchase of a new property is the most common time for this service. Ensuring you are the only one with access to your sanctuary is the primary goal of any lock replacement project.

Moving into a new home where previous owners or tenants might have copies of the keys.
Experiencing a home break-in or attempted forced entry that damaged the lock mechanism.

Frequently asked questions

How long does it take to change a residential lock?

A typical deadbolt or handle set installation takes about 20 to 30 minutes per door. If we are modifying the door frame for high-security hardware or installing fresh bore holes, it may take slightly longer to ensure a perfect fit.

Is it better to rekey or change the locks entirely?

While rekeying changes the internal pins to work with a new key, a lock change replaces the entire physical fixture. We recommend a full change if your hardware is older than 10 years, rusted, or structurally compromised.

Can you replace my old locks with smart locks?

Absolutely. We carry a variety of smart locks from brands like August, Schlage, and Yale. We can replace your traditional deadbolt with a keypad or Bluetooth-enabled system to modernize your Washington, DC home security.

Can you make all my new locks work with the same key?

Yes, if the locks are the same brand and model, we can often 'key them alike.' This allows you to use one single key for your front, back, and side doors, reducing keychain clutter.

Do you offer lock changes for sliding patio doors?

Yes, we provide specialized Residential Lock Change services for sliding glass doors, including heavy-duty patio locks and foot-actuated bolts that offer significantly better protection than standard factory latches.
