Home Lock Rekeying

Every pin-tumbler lock — the type found in the vast majority of residential and commercial doors across the Five Towns and Rockaways — contains a stack of small spring-loaded pins inside the cylinder. When the correct key is inserted, its unique series of cuts lifts each pin stack to exactly the right height, allowing the cylinder to rotate and the lock to open. Rekeying means a locksmith disassembles the cylinder, removes those pins, and replaces them with a new set sized to match a freshly cut key. Once reassembled, the old key hits the wrong heights and the cylinder refuses to turn — physics, not software, keeps intruders out.

Our technicians carry a wide assortment of key pins and driver pins compatible with the most common residential and commercial lock brands in New York, including Kwikset, Schlage, Baldwin, Medeco, and many others. If you have multiple locks on a door — a knob lock and a deadbolt, for example — we can rekey both to accept the same new key, a process called keying alike, so you're never fumbling through a ring of nearly identical keys at midnight after a flight lands at JFK.

There are specific situations where rekeying is clearly the smarter choice over full replacement. You've just bought a house in Cedarhurst or Inwood and have no way of knowing how many copies the previous owners handed out over the years — rekey immediately. A contractor, housekeeper, or dog walker who had a key is no longer in your life and you'd like to be certain access is revoked. A roommate moved out. A break-up happened. A key went missing somewhere between the A train and Atlantic Avenue. In every one of these scenarios, your lock hardware itself is perfectly functional; the only problem is that too many people have a key that works. Rekeying solves exactly that problem at a fraction of the replacement cost.

Rekeying is also the go-to solution for landlords managing rental properties across the Five Towns and Rockaways. New York law effectively expects tenants to have exclusive access to their unit, and handing incoming tenants re-coded locks — rather than hoping prior tenants returned every copy — protects both the tenant and you from liability. Many of our commercial clients in the JFK corridor rekey their facilities on a fixed schedule or any time a keyholder leaves the organization, which is a straightforward best-practice for access control without investing in a complete hardware upgrade.

Replacing a lock makes the most sense when the hardware itself is damaged, worn, or simply outdated — a builder-grade deadbolt installed in the 1990s that wobbles in the door, a lock with a compromised strike plate, or a situation where you're upgrading to higher-security hardware with anti-pick, anti-drill, or anti-bump features. If your existing locks are solid, though, swapping them out is unnecessary expense. Rekeying keeps the hardware you paid for and achieves the same security outcome — a key that no longer works simply does not work, period.

When you call or text us, we'll ask a few quick questions about your locks and your situation before we arrive. If we find on-site that rekeying is genuinely not in your best interest — say, the cylinder is damaged or the security grade is too low for what you need — we'll tell you plainly and walk you through replacement options. We confirm an exact price before any work begins, so there are no surprises on your bill. The price we quote depends on factors like the number of locks, the brand and type of cylinder, whether you need keys duplicated, and whether you're calling during regular hours or at 2 a.m. after realizing your keys are gone — but you'll know the full number up front.

Rutherford Locksmith Inc operates as a fully mobile service. There's no shop you need to visit, no lock you need to remove and mail in, and no waiting around for a technician driving in from outside the area. We're already in Rutherford, the Five Towns, and the Rockaways, and we stay available around the clock — 24 hours a day, 7 days a week, 365 days a year — because a lost key or a tenant change doesn't wait for business hours. Our goal on every call is to reach you quickly, work efficiently, and leave your door hardware in the same condition we found it.

We carry professional rekeying kits and key-cutting equipment in our service vehicles so the entire job — disassembly, pin replacement, cylinder reassembly, key cutting, and function testing — happens right at your door. We test every key multiple times before we close the job so you're not left with a lock that feels stiff or a key that occasionally doesn't catch. Licensed, insured, and local — that's the standard we hold ourselves to on every call, whether it's a single front-door deadbolt in Rockaway Beach or a six-unit rental building in Elmont.
