Rekey Locks NYC

Rekeying swaps the pins inside your existing lock so old keys stop working — same hardware, brand-new key — and Top Notch Locksmith & Security rekeys locks across NYC daily, all five boroughs, 24/7. It's usually the most cost-effective fix on our locksmith services menu when the lock itself is healthy; when it isn't, a full lock change is the honest recommendation instead.

Rekey vs. Lock Change: How to Choose

The question to ask: is the problem the lock, or the keys? If the hardware works smoothly and you just need old keys dead — after a move, a breakup, a lost ring, a staff change — rekey it. The lock stays, the pins change, and every existing copy becomes scrap metal. If the lock is damaged, worn, gritty, or you want stronger hardware on a street-facing door, replacement earns its higher cost. We carry both answers on the truck and quote both honestly, so you pick based on facts rather than upsell. Rekeying typically costs less because you're paying for skilled labor, not new hardware.

Move-In Rekeys and Lease Turnovers

Count the people who might hold a key to your new apartment: previous tenants, their exes, their dog walker, two contractors, and whoever the landlord lent a copy in 2019. A move-in rekey erases that whole list in one visit, which is why it should sit next to the WiFi setup on every NYC moving checklist. Landlords flip the same logic: rekeying between tenants is faster and cheaper than replacing decent hardware, and it keeps unit keys aligned with building master systems when there is one. Renters — check your lease first; rekeying the main lock usually involves the landlord, and we can coordinate that.

One Key for Every Door

Keyed-alike rekeying is the quiet upgrade nobody regrets: the deadbolt, the knob, the gate, and the basement door all answering to one key. For a commuter sprinting to a train, two fewer keys to fumble is a daily win; for a brownstone owner, it turns a janitor-grade key ring into a single cut of brass. We can also rekey Medeco and Mul-T-Lock high-security cylinders, where new keys are cut on restricted blanks — meaning a hardware store can't copy them, and key control actually stays controlled.

Common Questions

Is rekeying cheaper than changing the locks?

Usually, yes — you keep the hardware and pay for the pin work and new keys. You'll get a transparent quote for both options before any work begins.

Can a renter rekey an apartment lock?

Often, but check your lease — the main lock usually involves the landlord, and many buildings need unit keys to stay compatible with a master system. We coordinate that routinely.

How long does a rekey take?

It's a single-visit job in almost every case, including multiple doors keyed alike in the same appointment.

Can you rekey high-security locks?

Yes — we rekey Medeco and Mul-T-Lock cylinders and cut their restricted keys, which can't be copied at a hardware store.
