Lock Rekey & Replacement
When you move into a new home off Dunhams Corner Road, hand over keys after a lease ends, or simply misplace a set on a busy Tuesday, the question is never 'should I secure this lock?' — it's 'how fast can I get it done right?' Lock rekeying resets the internal pin configuration of your existing hardware so every old key becomes useless and only your new key works. It's the most precise way to reclaim control of who can enter, and for most standard cylinders it takes less time than a full lock replacement.

What Lock Rekey & Replacement Actually Involves — And Which One You Need
Rekeying and replacing are two distinct solutions to the same security problem. During a lock rekey, a trained technician removes the lock cylinder, disassembles the pin stack, and replaces the driver and key pins with a new configuration that matches a freshly cut key. The old key — no matter how many copies exist — no longer operates the lock. The hardware, the deadbolt body, the strike plate, and the finish all stay exactly as they are. For most residential doors with functioning Schlage, Kwikset, or similar brand cylinders, rekeying is the right call after a move, a lost key, a roommate change, or any situation where key control has been compromised.
Lock replacement makes more sense when the cylinder is worn and stiff, when the door knob lock or deadbolt is an outdated low-security model, when you are upgrading to a mortise lock for better forced-entry resistance, or when visible damage has compromised the mechanism. A mortise lock — the rectangular unit that fits into a routed pocket inside the door — offers a much larger footprint and more robust bolt throw than a standard cylindrical lock, which is why we see them specified frequently on older colonial-style homes in East Brunswick's established neighborhoods as well as on commercial storefronts. Our technicians assess the existing hardware before recommending anything, so you are never pushed toward a replacement when a rekey will do the job cleanly.

Lock Rekey Set for Every Door in the House — One Key, Every Lock
One of the most practical upgrades any homeowner can request is a lock rekey set: bringing every keyed entry point in the home — front door, back door, side garage entry, even a detached workshop — to a single matching key. This is called keying alike, and it eliminates the drawer full of nearly identical keys that no one can tell apart in the dark. For a rental property on New Street or a multi-unit building near the East Brunswick Public Library, a rekey set also lets a landlord issue a single master key that opens all units while giving each tenant a key that opens only their own door.
Our mobile setup means we carry pin kits compatible with the most common residential and commercial cylinders in the area. We can rekey a full set of door locks in a single visit, confirm each key turns smoothly before we leave, and cut additional copies on site if needed. If you have a smart lock rekey situation — say, a Schlage Encode or similar electronic deadbolt with a rekeyable cylinder — we handle the mechanical cylinder portion during the visit and walk you through the electronic credential reset so both sides of the lock are synchronized to your new access plan.

After a Move or Lost Key: Why Timing Matters for Home and Business Lock Rekey
The window between getting your keys at closing and the moment you actually sleep in the house is the highest-risk period most homeowners never think about. Previous owners, contractors, real estate agents, cleaning crews, and neighbors may all have copies of keys that fit your new front door. The same logic applies to a commercial lock rekey situation: when an employee leaves — especially under difficult circumstances — every lock that key touched is a potential liability until it is reset. East Brunswick's commercial corridor along Route 18 sees a steady volume of tenant turnover, and we regularly service businesses there that need cylinders rekeyed before the next business day.
A lost key creates a different but equally urgent problem. You don't know where it is or who has it, and replacing your wallet or bag doesn't change the fact that your address may be on something that was with those keys. For both scenarios — move-in and lost key — the fastest, most cost-effective first step is a professional lock rekey rather than a full replacement, unless the lock itself is damaged or undersized for the door. If you are unsure which option fits your situation, call (732) 327-3683 and describe what you have — we will give you a straight answer before scheduling anything.

Frequently asked questions
How much does a locksmith cost in NJ to rekey a lock?
There is no single flat rate because the final price depends on several factors: the type of lock being serviced (a standard cylindrical deadbolt costs less to rekey than a commercial-grade mortise lock), the number of locks included in the visit, the time of day (late-night and holiday calls carry a different rate than mid-morning appointments), your location within our service area, and whether any parts — new pins, a replacement cylinder, or cut keys — are needed. What we commit to on every call is confirming an exact price before a single tool comes out. You approve the quote, then we do the work. Call (732) 327-3683 for a specific number based on your actual situation.
What does the average locksmith charge per hour for a rekey job?
Most lock rekey work in residential settings is quoted per job rather than per hour, because the time required is predictable once a technician sees the hardware. A single-cylinder deadbolt rekey typically takes 15 to 30 minutes; rekeying a full set of doors takes longer but is usually quoted as a package. Factors that shift the price up include high-security or mortise lock cylinders, emergency or overnight timing, travel to areas at the edge of our service zone, and the need for replacement parts. We always confirm the all-in price before starting so you are not watching a clock wonder what the final bill will be.
How much will a locksmith charge to change a lock versus rekey it?
Rekeying is almost always less expensive than a full lock change because the existing hardware stays in place — you are paying for labor and a small set of replacement pins. A full lock change involves removing the existing unit and installing new hardware, which adds both parts cost and additional labor. That said, there are situations where replacement is the smarter long-term investment: a worn cylinder, an outdated low-security lock on a primary entry, or an upgrade to a mortise lock for a commercial door. Our technicians will tell you honestly which option fits your door, your security goals, and your budget, and give you an exact quote for each path before you decide.
Can a locksmith make a key from a lock during a rekey visit?
Yes. When we rekey a lock, we are already working inside the cylinder, which means we know the new pin configuration precisely. From that configuration, our technician can cut a new key on site using mobile key-cutting equipment — no trips to a hardware store required. If you need additional copies, we can cut those during the same visit. The only situation where key origination from a lock becomes more complex is with high-security cylinders that have patented keyways; those require the correct key blank, which we stock for the most common brands. Let us know how many copies you need when you call and we will confirm we have the right blanks on the truck.
Is East Brunswick, NJ a good fit for a smart lock rekey or is a standard deadbolt enough?
East Brunswick is a large, diverse township — the stretch of older colonials near Dunhams Corner Road and the newer construction near Edgebrook have different door preparations and different security baselines. A smart lock makes the most sense when you want keypad or app-based access alongside a mechanical backup, which is common for rental properties and home offices. For most primary entries, a properly rekeyed high-quality deadbolt is genuinely solid security. The honest answer is that the right choice depends on your door prep, your existing hardware brand, and how you actually use the entry point. Our technician can assess that on arrival and explain the trade-offs — including whether your current electronic deadbolt has a rekeyable cylinder we can service mechanically.
What is the difference between a mortise lock rekey and a standard cylinder rekey?
A mortise lock is a rectangular mechanism that sits inside a routed pocket in the door edge, with a separate cylinder (typically a removable oval or rim cylinder) that plugs into the body. Rekeying a mortise lock means extracting that cylinder, repinning it to the new key, and reinstalling it — leaving the full mortise body, latch, and deadbolt throw intact. It requires a slightly different tool set and pin kit than a standard cylindrical deadbolt, but our technicians carry both. Mortise locks are common on older East Brunswick homes with traditional door styles and on commercial storefronts, and they offer a larger bolt throw and more robust housing than most cylindrical locks, which is why many property owners choose to keep and rekey rather than replace them.
