Rekey or Replace? What to Do With Your Locks After Moving in DC

Think about every person who may have touched a key to your new home before you: the previous owner, their relatives, a house cleaner, a dog walker, a contractor who did the kitchen renovation three years ago. In a city as transient and densely populated as Washington, DC, key duplication is easy and often goes untracked. Even in newer buildings near NoMa or the Wharf, building management may have issued more copies than the records show. This is the core reason security professionals consistently recommend addressing your locks on day one — not day thirty.

The simple act of rekeying or replacing your locks severs that chain of unknown access. It's not about distrust of any one person; it's about establishing a clean, documented starting point for who has access to your home. If you're a renter, you have rights here too — DC tenant law generally permits you to request lock changes, and in many cases your landlord is required to act. Either way, doing nothing is the one option you want to avoid.

Rekeying means a skilled locksmith disassembles your existing lock cylinder and replaces the internal pins so that the old keys no longer work and a new key operates the lock. The lock hardware itself — the knob, deadbolt, or mortise lock body — stays in place. This is a practical, efficient solution when your locks are in good working condition, relatively modern, and you simply want to invalidate existing keys. For most standard deadbolts and door knob locks in good shape, rekeying is a straightforward service that gets the job done without replacing hardware that has years of useful life left.

Full lock replacement makes sense in a different set of circumstances: when the lock is visibly damaged, old, or malfunctioning; when you're upgrading to a higher security grade; when you're switching from a builder-grade door knob lock to a mortise lock for added strength; or when a lock has been tampered with and can no longer be trusted. Mortise locks, which sit inside a pocket cut into the door edge and are common in DC's historic rowhouses and older apartment buildings, offer substantially more resistance to forced entry than standard cylindrical locks. If your home currently has aging or low-grade hardware, replacement is often the smarter long-term investment.

Washington, DC has an enormous stock of pre-war and early-20th-century rowhouses, particularly in neighborhoods like Petworth, Brookland, and Takoma. These homes frequently feature mortise locks — the rectangular, multi-component lock assemblies installed inside a deep pocket in the door. A mortise lock typically combines a deadbolt, latch, and sometimes a night latch into one robust unit, making it significantly harder to kick in or jimmy compared to a surface-mounted cylindrical lock. If your new home has original mortise locks, they deserve special attention: they may be in excellent condition and simply need rekeying, or the mechanism may be worn and due for a full rebuild or replacement.

Newer construction and renovated properties throughout DC more commonly feature standard cylindrical deadbolts and door knob locks. These are simpler to rekey and easier to replace with upgraded hardware if you choose to step up your security. Regardless of lock type, a trained locksmith can assess the condition of your hardware during the same visit and give you an honest recommendation. Our team works with all lock types across DC — from antique mortise assemblies in Capitol Hill brownstones to modern smart-lock installations in Shaw condos — so you'll get advice matched to your actual door, not a generic upsell.

Even after you've sorted your locks, life happens. If you find yourself locked out of your house in DC, the first and most important step is to stay calm and avoid any actions that could damage your door or lock — forced entry attempts almost always make the situation worse and more expensive to repair. Start by checking whether any other entry point is accessible: a back door, a window you may have left cracked (on a ground floor only, and only if it's safe to access), or a trusted neighbor who may hold your spare key. If you live in a building with a property manager or super, they may be able to let you in during business hours.

If none of those options apply — which is most of the time, especially late at night or on weekends — calling a professional emergency locksmith is the right move. What to do when locked out of your house is straightforward: don't attempt to pick or force the lock yourself, don't let a stranger claiming to be a locksmith work without verifying who they are, and don't leave your home unsecured while you figure out next steps. Our mobile team covers all of DC 24 hours a day, seven days a week. We arrive with the tools and experience to get you back inside without damaging your lock or door — and before any work begins, we confirm your ownership or tenancy and provide a clear, up-front price. Call (704) 850-6756 any time — we answer around the clock.

Not every locksmith who shows up at your door operates the same way, and in a busy city like Washington, it pays to know what to ask. First, ask for identification and proof of business — a legitimate, experienced locksmith will have no issue showing you who they work for. You're fully within your rights to ask for this verification before allowing any work to begin; in fact, most professional locksmiths expect it and take it as a sign of a careful, aware customer. If you're a renter, a lease agreement or utility bill in your name is typically sufficient proof of residency. Homeowners can present a deed, closing documents, or a government-issued ID matching the property address.

When it comes to pricing, the factors that shape your final quote include the type of lock involved (a mortise lock service is more involved than a basic door knob lock rekey), the time of day (emergency locksmith calls outside regular business hours reflect the on-demand nature of the service), travel distance within the DC metro area, and whether any parts or new hardware are needed. What should never happen is a price that changes after the work is done. Our team provides an exact up-front quote before touching anything — no ambiguity, no surprise charges. We are insured, experienced, and equipped for residential, commercial locksmith work, and automotive services throughout the Washington area.
