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

New York law (RPL Section 227-a) gives landlords the right to manage key distribution, but it does not guarantee that every copy of your key has been collected and accounted for. In practice, keys get duplicated without authorization, maintenance workers carry master copies that rarely change, and turnover in busy buildings means the paper trail for who holds a copy of your lock's key combination is virtually nonexistent. The risk is not hypothetical — NYPD precinct data consistently shows that a meaningful percentage of residential burglaries in boroughs like Brooklyn and the Bronx involve no forced entry at all, meaning someone walked in with a key.

The answer is not to live in fear. It is to take a single afternoon — or a single phone call — to make your lock respond only to keys you control. This is exactly what rekeying and lock replacement accomplish, and understanding the difference between the two will help you decide which one you actually need.

Rekeying is the process of changing the internal pin configuration of your existing lock cylinder so that your old keys no longer work and a new key cuts are required. The lock hardware stays exactly where it is — only the tumblers inside change. This is ideal when your existing lock is in good working condition, the hardware is solid, and you simply want to invalidate any outstanding copies. A trained locksmith can typically rekey a standard cylinder in a matter of minutes per lock. If your apartment has a classic New York mortise lock — the large, rectangular mechanism recessed into the door edge that's common in pre-war buildings across the West Village, Park Slope, and Washington Heights — rekeying is often the most seamless path because the mortise lock body itself is expensive to replace and usually built to last generations. An experienced locksmith will extract the cylinder, repin it to a new key, and reinstall it without disturbing the trim or the door.

Replacing the lock entirely makes sense when the existing hardware is worn, damaged, poorly rated for security, or simply not the right fit for your lifestyle. This is also when you might consider upgrading to a smart lock with a keypad. If you have ever wondered how to change the code on a door lock or whether you can change the code on a keypad door lock, the answer is yes — but the specific steps depend entirely on the brand and model you install. For a Kwikset SmartKey or a Schlage encode, how to change the door lock code usually involves a dedicated programming button, a sequence of key presses, and a reset procedure outlined in the manufacturer's guide. A qualified locksmith can handle the installation and walk you through reprogramming so you are not guessing. If you happen to have a standalone combination lock on a storage unit or secondary access point and are wondering how to change the code on a combination lock, that process is model-specific but generally involves pressing a reset pin while turning the dial to your new sequence — always confirm with your lock's documentation.

Not all New York apartment doors are the same, and your lock strategy should match your actual hardware. Pre-war buildings — think anything constructed before 1940, which covers enormous swaths of Manhattan, Brooklyn, and Queens — almost universally feature mortise lock systems. These are robust, multi-component locks that include a deadbolt, a latch, and sometimes a night-latch, all housed in a single mortise lock body. They are excellent locks when maintained, but the cylinders can wear over decades of use, and the sheer age of the hardware means rekeying by a skilled locksmith is far preferable to a DIY attempt with the wrong tools. Tampering with an old mortise lock incorrectly can crack the casting and require a full door edge repair.

Post-war and modern buildings are more likely to feature a door knob lock paired with a separate deadbolt, or a lever-handle setup. These are simpler to rekey or replace and have a wider range of compatible aftermarket cylinders. Whichever system you have, the single most important step is to have a professional assess it before assuming a standard solution will apply. If you want to know how to change the code on a honeywell door lock or how do I change the code on my door lock after installing a new smart lock, your locksmith can configure the unit during installation and demonstrate the reset process so you have full control going forward.

One often-overlooked scenario in New York high-rises: the building may have a keyed intercom system or a key-fob-based front door that the landlord controls separately. Rekeying your apartment door does not affect those systems, but it does mean the one door between your belongings and the world is under your authority alone — and that matters.

This is the question every new renter asks, and the honest answer is that no single number applies universally across New York City. Several factors shape the final quote: the type of lock involved (a basic door knob lock cylinder costs less to rekey than a full mortise lock assembly), the number of locks on your door, whether any parts need to be sourced and replaced, the time of day, and your specific location in the five boroughs. Emergency locksmith calls — say, you moved in and discovered your lock was already compromised at 11 PM — carry a different pricing structure than a scheduled afternoon appointment. What never changes is this: 7th Ave Locksmith NYC confirms an exact price before any work begins, so you know precisely what you are agreeing to with no after-the-fact surprises. How much does a NYC locksmith cost, or how much is the average locksmith charge? The only truthful answer is that it depends on those variables — anyone quoting you a flat number over the phone without knowing your lock type and location is guessing, and guessing is how you end up with surprise fees. Call us at (646) 274-4573 and we will assess your situation and give you a real number upfront.

Emergency locksmith calls are a separate category worth understanding. How much will an emergency locksmith cost, or how much does an emergency locksmith cost near me? After-hours and emergency calls typically reflect the urgency and the logistics of dispatching a mobile technician at any hour across a city as spread out as New York. The price is real and it is confirmed before work starts — but it is not the same as a mid-afternoon scheduled appointment, and any provider who tells you otherwise is not being straight with you. Our team is mobile, dispatched 24 hours a day, and covers neighborhoods from Midtown Manhattan to the outer boroughs.

Here is a straightforward process to follow when you move into a new apartment: First, check your lease. Some landlords prohibit tenants from changing locks without written permission; others require only that you provide a copy of the new key. Review your agreement before calling a locksmith — or ask your landlord proactively, because many will approve the request without hesitation when it is framed as a security measure. Second, count your locks. NYC apartments often have more points of entry than renters initially notice: the main deadbolt, the door knob lock, a secondary chain or latch (which may not need rekeying but should be inspected), and sometimes a building storage unit. Third, identify your lock type so the locksmith arrives prepared. A photo of the lock hardware sent in advance helps the technician bring the right cylinder blanks or parts. Fourth, ask about key control — specifically whether the new cylinder uses restricted key blanks that cannot be duplicated at a standard hardware store without authorization. This is an upgrade worth considering if you value long-term key accountability.

Fifth, and most importantly, schedule the work before you start bringing in furniture and boxes, not after. The window between receiving your keys and moving day is when your door is most vulnerable and when arranging a locksmith is most convenient. 7th Ave Locksmith NYC offers 24/7 mobile service across New York — our technicians come to you, work on-site, and have you set up with fresh, accountable keys typically within the same visit. Whether you need a quick rekey of a single mortise lock cylinder, a full hardware upgrade with a new smart keypad, or you have questions like how to change the code on my door lock after an install, call (646) 274-4573 and we will walk you through it — or come to you and handle it in person.
