Should You Rekey or Replace the Locks After Moving Into a Brooklyn Apartment?

When a locksmith rekeys a lock, they open the lock cylinder and swap out the small internal pins and springs so that the old key no longer works and a new key operates the lock instead. The hardware on your door stays exactly where it is — the mortise lock body, the strike plate, the trim — none of it moves. This is the core answer to the question of how do you rekey a lock: a skilled technician removes the cylinder, replaces the pin stack to match a new key cut, and reinstalls everything. The whole process is typically faster than a full replacement and requires no drilling or door modification.

Lock replacement, on the other hand, means removing the entire lock mechanism — cylinder, body, and all hardware — and installing a completely new unit. This is the right call when the existing hardware is damaged, outdated, or simply not up to the security standard you want. In a city neighborhood like Bushwick or Bed-Stuy, where street-level security matters, upgrading from a worn builder-grade lock to a solid mortise lock with anti-pick, anti-drill pins can meaningfully change the security profile of your front door. Both services have a legitimate place — and a professional locksmith will tell you honestly which one your situation calls for.

The rekeying process itself follows a consistent set of steps regardless of brand: the locksmith uses a follower tool to remove the cylinder plug, drops out the old driver and key pins, inserts a new pin set matched to the new key's cuts, reassembles the cylinder, and tests it thoroughly before returning the hardware to the door. Can you rekey any lock? The short answer is: most keyed locks, yes — standard deadbolts, knob locks, lever locks, and classic mortise locks are all rekey-friendly. The exceptions are locks that are severely corroded, physically damaged, or use proprietary restricted-key systems that require factory retooling.

One increasingly common question we hear from tenants in newer Brooklyn buildings is: can you rekey a smart lock? In many cases, yes. Several smart lock models allow a trained technician to rekey the physical key cylinder that serves as a backup entry method, even when the primary entry mode is a keypad or app. A follow-up we get often is whether you can rekey a smart lock without the original key — and the answer depends on the specific model. For some units, a locksmith can use specialized tools to decode the existing pins and rekey without the original key present. For others, the manufacturer requires the original key or a factory reset. If you have a Yale smart lock — a common choice in renovated Brooklyn apartments — a qualified locksmith can often rekey a Yale smart lock through the physical cylinder, though model-specific limitations apply. When in doubt, call us before assuming it's impossible.

There are scenarios where rekeying simply isn't enough — and recognizing them early saves you from a false sense of security. If your apartment door has an old, single-cylinder mortise lock with no anti-pick protection and visibly worn keyway, rekeying the same vulnerable cylinder only solves the key-copying problem, not the forced-entry problem. Brooklyn's older housing stock — especially along corridors like Flatbush Avenue or in the row houses of Prospect Lefferts Gardens — is full of original mortise locks from the 1940s and 1950s that still function but offer minimal resistance to modern bump-key or picking attacks. In those cases, a mortise lock upgrade is the smarter investment.

A mortise lock is the rectangular lock body that fits into a routed pocket in the door edge, as opposed to a cylindrical bore-through lock. High-quality mortise locks from manufacturers like Schlage or Kwikset offer significantly more bolt throw, reinforced strike integration, and resistance to lateral force than standard cylindrical locks. As a commercial locksmith serving businesses throughout Brooklyn, we install heavy-duty mortise locks on storefronts, office suites, and multi-family building entrances every day — the same hardware is absolutely appropriate for a ground-floor apartment or a building with a shared vestibule. If your door currently has a door knob lock as its only security layer, that's almost always a replacement conversation, not a rekeying one. A door knob lock alone provides minimal security and should be supplemented or replaced with a deadbolt or mortise lock. Call 718-928-6890 and a member of our team can assess your door and hardware remotely or in person and tell you exactly what makes sense.

A question we hear constantly is: what is the average charge for a locksmith, or how much does an emergency locksmith cost near me? The honest answer is that no responsible locksmith quotes a flat rate without knowing the specifics of the job. The factors that shape your final price include the type and brand of lock currently installed, whether you need a mortise lock service or a simpler cylindrical rekey, the number of locks being serviced, the time of day (an emergency locksmith responding at 2 a.m. operates differently than a scheduled afternoon appointment), travel distance within the Brooklyn service area, and whether new parts or hardware need to be supplied. At Bedford Ave Locksmith, we confirm an exact, up-front price before any work begins — no surprise additions when the job is done.

What is the meaning of locksmith, really, in a practical sense? It's a trained trade professional who understands the mechanical and electronic security of doors, locks, safes, and access systems — not just someone who cuts keys at a kiosk. What does the locksmith do beyond turning a wrench? A skilled locksmith assesses your full door security, identifies weak points in your current setup, recommends the right hardware for your specific door and threat environment, and installs or services it correctly so the hardware performs as designed. How much should an emergency locksmith cost? Enough to ensure the person showing up is insured, experienced, and accountable — and transparent about price before touching your door. We are insured and our team is trained to handle everything from a standard rekey to a full high-security mortise lock installation on short notice.
