Rekey or Replace? What to Do With Your Locks After Moving In

Rekeying means a trained locksmith reconfigures the internal pin tumblers of your existing lock cylinder so that all old keys stop working and a fresh set of new keys operates the lock. The hardware on your door stays exactly the same — deadbolt, knob, handle, strike plate and all — only the internal secret changes. For most new homeowners who move into a property with locks that are in good physical shape and already at a decent security grade, rekeying is the fastest, most practical way to cut off access for anyone who held a key before you. It's especially effective when you want to put every exterior door on a single key, a process called master-keying, so you're no longer juggling four different keys for four different doors.

Where rekeying falls short is when the lock itself has problems. A mortise lock with a worn cam, a deadbolt with a cracked cylinder housing, or a door knob lock whose latch is sticking — these issues won't be fixed by rekeying alone. If the hardware is aging, damaged, or simply a low-grade product that a determined person could defeat with basic tools, rekeying is putting a fresh coat of paint on a fence that needs replacing. In those cases, a full lock replacement is the wiser investment. Not sure which camp your locks fall into? Our team offers free consultations so you can get an honest assessment before committing to either path — call 973-604-2305 and we'll talk it through with you.

When replacement is the right call, the type of lock you choose matters enormously. A standard door knob lock provides basic privacy but almost no real forced-entry resistance on its own — the latch bolt is spring-loaded and can be compromised quickly. A single-cylinder deadbolt is a major step up, but the gold standard for many Chatham Township homes, especially older properties with thick solid-wood doors, is the mortise lock. A mortise lock sits inside a precisely cut pocket — or mortise — in the door edge itself, combining a deadbolt, a latch, and sometimes a lever handle into one integrated unit. Because the lock body is embedded in the door rather than surface-mounted, it distributes force across the door structure rather than concentrating it at two small screws. Brands like Schlage and Kwikset offer well-engineered mortise lock options that our team installs regularly throughout the Chatham area.

High-security upgrades worth considering include locks with anti-pick, anti-drill, and anti-bump pins; reinforced strike plates anchored with three-inch screws into the door frame stud; and smart-lock cylinders that allow keypad or app-based access without sacrificing grade-one deadbolt strength. If you're also securing a home office, a detached garage, or a basement workshop — spaces that effectively function like small commercial properties — our commercial locksmith services cover multi-point locking systems and access-control hardware designed for higher-traffic or higher-stakes environments. Every installation our team performs includes a door and frame inspection, because even the best mortise lock won't perform well if the frame itself has soft wood or a poorly aligned strike.

Key cutting isn't just duplicating a key on a machine. Precision key cutting for high-security cylinders, laser-cut sidebar keys, transponder car keys, and restricted keyways (keys that can't be duplicated at a hardware store without authorization) all require different equipment and expertise. When you rekey or replace locks during a move-in, it's also the ideal moment to have a deliberate spare-key strategy: decide exactly how many copies exist, who holds them, and where your emergency spare lives. A locked-out-of-house situation — knowing what to do if locked out of house is something every homeowner should think about before it happens, not during a stressful moment at midnight — is far easier to handle when you've already placed a spare key with a trusted neighbor or family member rather than under a doormat.

If you do find yourself locked out, the practical steps are straightforward: check every door and window you know to be unlocked through normal use, contact a household member who may have a key, or retrieve your pre-arranged spare. If none of those options are available, calling an experienced, insured locksmith is the safe and legitimate path — it protects your door, your lock hardware, and your own safety. What to do when locked out of house is not a moment to experiment with improvised tools or techniques that can damage the lock cylinder, void a manufacturer warranty, or — in a worst case — attract the attention of concerned neighbors or local police. Our mobile team operates around the clock and can reach most Chatham Township addresses quickly, verify your identity and ownership, and get you back inside without damage to your door or lock.

Knowing what to do if you get locked out of your house is only part of the picture for Chatham homeowners. Lockouts happen in parking lots, office buildings, and storage units too. Our 24/7 emergency locksmith service covers residential lockouts, automotive lockouts — including high-security transponder-key vehicles and push-button ignition cars — and commercial lockouts for business owners who need access to their property outside normal hours. Because we're a fully mobile operation, we come to you: there's no shop you need to tow a car to, and no trip you need to make with a broken key in your pocket.

A common question we hear is 'What locks can locksmiths not open?' — and the honest answer is that a skilled locksmith can open virtually any lock through non-destructive techniques given the right tools and enough time, but certain ultra-high-security designs (like some biometric vault locks or multi-custody safes) are intentionally engineered to be extremely resistant even to professional tools. For everyday residential and commercial locks, a trained locksmith will almost always have a non-destructive method available. Another question, 'How much does a locksmith cost in NJ?' or 'How much should an emergency locksmith cost?', comes up constantly. The honest answer is that the final price depends on the specific lock type involved, the time of day (after-hours calls involve different resource costs), the travel distance to your location, and whether parts like a new cylinder or lock body are needed. What we commit to is confirming an exact price upfront before any work begins — no surprises on the invoice. The same principle applies whether someone asks us 'How much is the cheapest locksmith?' or simply wants to understand what drives the quote: transparency from the first call, every time.

Chatham Township is a genuinely diverse mix of housing stock — century-old Victorians, mid-century colonials, and newer construction — and the right lock solution isn't the same for every door. A 1920s front door with a mortise lock pocket already routed into its edge just needs the right mortise lock cartridge and trim. A 1970s colonial with a standard bore pattern may be best served by a high-grade deadbolt and a reinforced door knob lock combo. A newly built home may already have a smart-lock rough-in. If you're unsure what you have, what you need, or what your budget priorities should be — call 973-604-2305. We'll walk through the options with you at no charge, and there's never pressure to purchase anything on the spot.

We also want to note something for neighbors in the broader Chatham area, including those who might wonder 'Is there a locksmith in Glenmore Park?' — our mobile service radius extends well beyond Chatham Township's borders, and if you're in a surrounding community and need a skilled hand, reach out and we'll let you know if we can get to you. Chatham has long attracted residents who appreciate craftsmanship and attention to detail — it's the kind of town where historical figures like figures connected to New Jersey's rich political and academic history have called home, and where homeowners take pride in their properties. We take the same pride in the quality of every lock installation and rekey we perform here. Our team is insured, experienced, and treats every job — from a simple door knob lock rekey to a full mortise lock replacement — with the same professional care.

Our full service menu covers every access-control need a Chatham homeowner, driver, or business owner is likely to face: residential lock rekeying, residential lock replacement, mortise lock installation and repair, deadbolt installation, door knob lock replacement, high-security lock upgrades, smart lock installation, master key system design, key duplication, restricted keyway cutting, laser-cut key cutting, transponder key programming, car key replacement, automotive lockout service, ignition repair and replacement, trunk lockout service, commercial lock rekeying, commercial deadbolt installation, access control panel installation, push-button keypad lock installation, file cabinet and desk lock service, mailbox lock replacement, garage door lock service, padlock replacement, and safe lockout assistance. If your need isn't on that list, call us — chances are we handle it.

Here is the practical framework: if your locks are in good mechanical condition, from a reputable manufacturer, and the only concern is unknown key copies floating around — rekey. If your locks are worn, low-grade, visibly damaged, or were installed more than ten to fifteen years ago on an exterior door — replace, and consider upgrading to a mortise lock or a grade-one deadbolt with a reinforced strike. If you're moving into a home where you have both concerns — old hardware and unknown key history — do both simultaneously to save a service call.

What to do if you're locked out of your house in the middle of this process, or any other time, is simple: don't force anything, don't try improvised entry methods, and call a professional who will verify your identity, protect your door, and get you back inside cleanly. What to do when your locked out of your house at 2 a.m. on a cold Chatham night is the same answer — we're available around the clock, every day of the year. Call 973-604-2305 and our mobile team will be on the way.

Rekeying and lock replacement are not complicated decisions once you know what to look for — and now you do. Take a walk around your new home, test every exterior lock, note which ones feel smooth and which feel stiff or loose, and think about whether you want all your doors on a single key. Then call us. We'll confirm availability, discuss the specifics of your door hardware over the phone, and give you a firm, upfront quote before we touch anything.
