Lock Change & Rekeying NYC

Need to change the locks on a NYC apartment, house or office? There are two ways to do it, and most people only need the cheaper one. A full lock change means new hardware on the door: new deadbolt, new cylinder, new keys. Rekeying keeps the hardware you already have and re-pins the inside so the old keys stop working and only your new ones do. Both give you the same result: nobody with an old key can get in. Rekeying just costs a fraction of a lock replacement and takes about an hour.

SwiftLocksmith does both, same-day, across all five boroughs. We will tell you honestly which one your door needs when we see it. If your existing locks are sound, we will rekey them and you will pay less. We only recommend replacing the hardware when it is worn, damaged, low-grade, or when you want to upgrade to a high-security cylinder.

Lock rekeying is the most cost-effective way to take full control of who can enter your NYC home, apartment or office without buying brand-new hardware. SwiftLocksmith's licensed technicians visit you anywhere in Manhattan, Brooklyn, Queens, the Bronx and Staten Island, disassemble each lock cylinder on-site, swap the internal pins to a brand-new key bitting, and hand you a fresh set of keys, usually in under an hour per lock. Your old keys stop working immediately, which is exactly what you need after moving into a new apartment, losing a key on the subway, ending a roommate or contractor relationship, or finalising a co-op closing.

We rekey every common NYC lock format, including Schlage, Kwikset, Yale, Mul-T-Lock, Medeco, Arrow and Sargent, and we can match multiple locks to a single key (keyed-alike) so one key opens your front door, mailbox and roof-deck door. For brownstones and townhouses, we also rekey rim cylinders and Segal-style vertical deadbolts that are common across pre-war Brooklyn and Manhattan stock. Co-op and condo residents appreciate that rekeying is fully reversible and almost always permitted under standard alteration agreements because no door, frame or strike modifications are made. Perfect when your board would otherwise need to approve a full lock change.

For landlords and small property managers we run keyed-different or master-keyed systems across multiple units so each tenant has their own key while you keep one master that opens everything. Pricing starts at $75 per cylinder for standard residential locks; high-security cylinders like Medeco Maxum, Mul-T-Lock MT5+ and Schlage Primus are quoted on-site because they require restricted key blanks. Same-day mobile service is available 7 days a week and most jobs across NYC can be dispatched within an hour of your call.
