Should You Rekey the Locks After Moving Into a NYC Apartment?

When a locksmith rekeys a door lock, they are not replacing the hardware on your door. Instead, they disassemble the lock cylinder and swap out the small internal pins — called key pins and driver pins — so that the old key no longer operates the lock and a freshly cut key does. The tumblers inside are reconfigured to match a new key's unique cut pattern. The lock body, the bolt mechanism, the strike plate, and all the exterior hardware stay exactly where they are. This is why rekeying is faster and less costly than a full lock replacement.

For a standard pin tumbler cylinder — the kind you find in most residential deadbolts and door knob locks across New York City — a trained locksmith can complete the rekey in a matter of minutes per lock. The process requires the current working key (or a technique called impressioning if the key is lost), a plug follower tool, the correct replacement pins from a pinning kit, and a steady hand. Because the labor is light and no new hardware is purchased, the only factors that affect your final quote are the number of locks, the lock brand and type, and whether the call is during standard hours or an after-hours visit. A professional from our team will confirm an exact price before touching anything.

This is one of the most common questions we hear, and the honest answer is: most standard locks, yes — but not all. Nearly every pin tumbler deadbolt from major hardware brands can be rekeyed as long as you have the current working key and the lock is in good mechanical condition. The classic mortise lock, which you will find on the vast majority of pre-war apartment doors throughout Manhattan, Brooklyn, and Queens, is absolutely rekeyable. Mortise locks are the rectangular, cassette-style units that sit inside a pocket cut into the door edge — they're more complex internally than a standard deadbolt, which is why mortise lock rekeying is a specialty service and a core part of what our team handles every day across the five boroughs.

Where things get more complicated: high-security locks with sidebar mechanisms, locks that are heavily worn or damaged, and certain proprietary formats may limit your options. As for smart locks — yes, you can rekey a smart lock, depending on the model. Some smart locks use a traditional key cylinder as a backup entry method, and that cylinder can be rekeyed just like any standard lock. However, if you are asking can you rekey a smart lock without the original key, the answer depends on the specific model. Certain Yale smart lock models, for example, allow the electronic access codes to be fully reset through the app or a factory reset procedure, effectively clearing all previous user credentials — no physical key required for that part. Our team works with both traditional and electronic lock systems and can advise you on the right approach for whatever is on your door.

If you have moved into a pre-war building anywhere along Bleecker Street, West 4th, or the side streets threading through Greenwich Village, there is a good chance your front door has a mortise lock. These locks are robust, time-tested, and genuinely difficult to force — but they are also the type most likely to have had multiple key copies floating around over decades of tenant turnover. A mortise lock rekey clears that entire history. The cylinder is pulled from the mortise body, repinned to a new key, and reinstalled. The rest of the lock — the elegant escutcheon plate, the lever or knob trim, the latch — is untouched. It is the most efficient way to reclaim security in a building where the landlord may or may not have kept strict key control records.

Our mobile team serves Greenwich Village and the surrounding neighborhoods continuously, which means we are familiar with the door configurations, building layouts, and lock hardware common to that area. If you need a same-day rekey after picking up keys from a landlord, or if you want to consolidate multiple locks so that one key opens your deadbolt, door knob lock, and mailbox, we can handle that in a single visit. Call 646-722-6780 and we will have someone at your door, typically within the hour, any time of day or night.

Yes — and this is one of the most practical, underused services we offer. If your apartment has a deadbolt and a door knob lock, or a deadbolt and a secondary mortise lock, they may currently require two different keys. A locksmith can rekey both cylinders to operate on the same key, a process called key matching or key control. This is especially valuable in NYC apartments where multiple entry points — front door, building lobby, basement storage, or a secondary apartment entrance — each have their own lock. Rather than carrying a ring of keys, one correctly matched key can operate all of them after rekeying.

The same logic applies in the opposite direction: if you want to ensure that no old key can open your new home, and you want fresh keys cut at the same time, we can rekey all your locks to a single new key in one visit. This is the cleanest solution for new tenants and is far more thorough than simply changing the locks outright — unless the existing hardware is damaged, outdated, or you are upgrading security for another reason.

Rekeying is a planned, preventive service — but not every lock situation is planned. If you are locked out, if a key breaks inside a mortise lock cylinder, or if you discover signs of tampering on a door knob lock or deadbolt, you are dealing with an emergency locksmith situation. What defines an emergency situation in the context of locks and access control? Generally: any circumstance where you are unable to safely enter or secure your property, where evidence of a break-in attempt is present, or where a lock failure is actively preventing occupancy. In those cases, waiting for a scheduled appointment is not reasonable, and our 24-hour service exists precisely for those moments.

We also serve commercial clients throughout the New York area. As a commercial locksmith team, we handle master key systems, high-security mortise lock installations, access control hardware, and rekeys for office suites, retail storefronts, and multi-unit residential buildings. If you are a property manager handling turnover for several units at once, we can coordinate a single visit to rekey multiple apartments efficiently. The factors that shape your final quote on a commercial job include the number and type of locks, the complexity of any existing master key hierarchy, travel distance, and whether the work needs to happen outside standard business hours. We provide an exact confirmed price before any work begins — no surprises on the invoice.
