Rekey or Replace? What to Do With the Locks When You Move In

The Bronx is a borough of neighborhoods — each with its own rhythm, its own building stock, and its own security realities. A pre-war building in Fordham with original door hardware is a very different situation from a newly renovated unit in Hunts Point with a brand-new deadbolt. But in both cases, one thing is true: you have no way of knowing how many copies of your key are floating around. A responsible previous tenant may have returned every copy. Or there may be duplicates with a neighbor, a building super, an ex-partner, or a dog walker who was never told the lease changed hands. Rekeying or replacing your locks isn't paranoia — it's basic due diligence, and in New York, it's entirely your right as a new occupant.

South Bronx Locksmith is a 24/7 mobile locksmith team that operates throughout the Bronx, from Riverdale down to Port Morris and everywhere in between. We come to you — no shop visit required — and we carry the hardware and tools to handle everything from a simple rekey to a full mortise lock installation on the same visit. If you've just moved in and aren't sure where to start, call us at (347) 708-8794 and we'll walk you through your options before we ever show up at your door.

Rekeying is the process of reconfiguring the internal pin tumblers of your existing lock cylinder so that the old keys no longer work and a new key operates the lock. It's a smart, cost-effective solution when the lock itself is in solid mechanical condition — no wobble, no grinding, no visible wear on the cylinder face or bolt. If your apartment has a functioning deadbolt or door knob lock that's less than several years old and shows no signs of damage, rekeying is almost always the right first move. It renders every existing key useless and gives you a fresh start without tearing out hardware that's doing its job.

Replacing the lock entirely makes more sense in several situations: the current hardware is visibly damaged, corroded, or has been forced at some point; you want to upgrade from a basic door knob lock to a high-security deadbolt or a mortise lock; the building's doors use an older keyway that's widely distributed among many residents; or you simply want modern hardware with features like anti-pick pins, anti-drill plates, or smart-lock compatibility. A mortise lock — the type that fits into a rectangular pocket cut into the door edge — offers significantly more strength and pick resistance than a standard cylindrical lock, and it's what we often recommend for ground-floor units or street-facing doors in higher-traffic Bronx neighborhoods. Our team can assess your existing setup on the spot and give you an honest recommendation with no pressure to buy more than you need.

Moving day is chaotic, and lockouts happen more often than people expect — a door slams shut with the keys inside, a lock sticks mid-move, or a fresh rekey doesn't go as planned and now nothing works. If you find yourself in a situation where you're locked out of your house, the first step is to stay calm and check your options methodically. Look for any other access points you have authority to use — a back door, a building super with a master key, or a trusted neighbor who may have a spare. Verify that all windows and secondary doors are also secure before assuming there's no way in.

If none of those options apply, do not attempt to force entry yourself — damaged door frames and broken locks create a bigger problem and a bigger bill than a professional service call. What to do when locked out of your house is straightforward: call a trained locksmith who can verify your identity and right of occupancy, then use professional tools to open the door without destroying anything. South Bronx Locksmith responds across the Bronx 24 hours a day, seven days a week — including weekends, holidays, and late-night moving day scrambles. Call (347) 708-8794 and someone will pick up every time.

South Bronx Locksmith handles a wide range of residential, automotive, and commercial locksmith needs throughout the Bronx. Here is a representative list of what our team handles on a regular basis: residential lock rekey (single cylinder and double cylinder), mortise lock installation and repair, deadbolt installation and upgrade, door knob lock replacement, high-security lock installation with anti-pick and anti-drill features, smart lock and keypad lock installation, master key system setup for multi-unit buildings, lock cylinder replacement, broken key extraction from locks and ignitions, car door unlock and automotive lockout response, car key replacement and key cutting, transponder key programming, ignition cylinder repair and replacement, garage door lock service, sliding door lock installation, window lock and sash lock installation, mailbox lock replacement, padlock and hasp installation, commercial locksmith services for offices and storefronts, commercial-grade deadbolt and mortise lock installation for business doors, access control system consultation, emergency lockout response (residential and commercial), lock rekeying after tenant turnover for property managers, safe opening and combination change, and security assessment and hardware recommendation for new move-ins.

Every one of these services is performed by experienced, insured technicians who arrive in a fully stocked mobile unit. We don't subcontract calls or send someone unfamiliar with the job — the person who answers your call is connected to the team that will actually show up. For new Bronx homeowners and tenants especially, we recommend asking about our move-in security assessment, where a technician reviews every entry point and gives you a prioritized list of what actually needs attention versus what can wait.

One of the most common questions we get — right alongside 'who is the best locksmith near me in the Bronx, NY?' — is about cost. How much is a locksmith in the Bronx? How much should locksmiths charge? How much does a locksmith charge per hour? How much should an emergency locksmith cost? These are fair questions, and we'd rather explain them honestly than throw out a number that doesn't apply to your situation. The final price for any job depends on several real variables: the type and brand of hardware involved (a Kwikset rekey is a different scope than a Schlage high-security mortise lock installation), the time of day (emergency overnight calls involve different logistics than a standard daytime appointment), travel distance within the Bronx, and the specific parts or materials your job requires.

What we commit to is full price transparency before any work begins. We confirm the exact quote up front — no surprise fees added at the end of the job. If the scope changes once we're on site (for example, we discover the existing lock body is cracked and can't be rekeyed safely), we stop and discuss before we proceed. We do not operate with hidden trip fees or mystery surcharges. As for who is the cheapest locksmith — that's genuinely not the right question to ask when it comes to the hardware protecting your home. The better question is who gives you an honest quote and stands behind the work, and that's what South Bronx Locksmith is built on.

Yes — South Bronx Locksmith is a fully mobile, 24/7 operation. That means whether it's 2 a.m. on a Tuesday or noon on Thanksgiving, someone answers when you call (347) 708-8794. We understand that lock problems don't schedule themselves around business hours, and the Bronx doesn't slow down at night. Our team regularly handles late-night residential lockouts in Co-op City, early-morning car lockouts near Yankee Stadium, and weekend lock change requests from new tenants who just got their move-in date pushed up.

And yes — if you can't open your car door and you're in a rush, we can help. Automotive lockouts are one of our most common calls, and we handle them with the same speed and professionalism as residential jobs. We can unlock your vehicle, cut a replacement key on site, or program a new transponder key depending on your make and model — all without damaging your door or window. If you've locked your keys in the car in a Bronx parking lot or gotten stranded after a late shift, don't risk your safety waiting or trying to force the door. Call us and we'll come to you.
