You just got the keys to your new home on Hillsdale Avenue or somewhere off Broadway — congratulations. But before you unpack a single box, there's one question worth asking: how many people out there still have a working key to your front door? The previous owners, their real estate agent, a house-sitter, a neighbor who watered plants — any of them could have a copy. Changing the locks or rekeying them isn't paranoia; it's the single most practical security step a new homeowner can take, and in most cases it costs far less and takes far less time than people expect.
This guide breaks down the real difference between rekeying and replacing your locks, explains when each option makes sense, walks through how to change the code on a door lock if you have a smart lock, and tells you exactly what to ask when you call a locksmith. Rapid Keys Locksmith serves Hillsdale, NJ and the surrounding Bergen County communities around the clock — here's everything you need to make the right call.
## Rekey vs. Change the Lock: What Actually Happens Inside the Door
Rekeying and replacing are two very different processes, even though the end result — locking out every old key — is the same. When a locksmith rekeys a lock, they disassemble the cylinder and swap out the small internal pins so that only your new key operates the mechanism. The hardware itself stays in place. This is almost always the faster, more cost-effective route when the existing lock is in good condition. If you have a quality deadbolt already installed, there's rarely a reason to throw it away just to feel secure.
Replacing the lock entirely means removing the old hardware and installing new. This makes sense when the lock is worn, damaged, an outdated style that no longer aligns with your door frame, or when you want to upgrade — say, from a basic door knob lock to a heavy-duty mortise lock or a smart deadbolt. A mortise lock, for context, is the type that fits into a deep rectangular pocket cut into the door edge; it's stronger than a standard bored lock and is common on older Bergen County homes and on commercial properties. If your new home has one, a skilled locksmith will rekey the cylinder rather than gut the whole unit — saving you significant time and expense.
## How to Change the Code on a Door Lock (Smart Locks and Keypads)
If your new home came with a smart lock or electronic keypad, rekeying looks a little different. Instead of swapping pins, you're clearing the old access codes and programming new ones. The exact steps depend on the brand and model. On many Schlage encode or similar deadbolts, you hold the outside programming button, enter a default code, and then set your new code. On a Honeywell door lock, how to change the code typically involves pressing the Program button on the interior panel, entering the existing master code, and following the prompts to create a new one — the process is outlined in the manual, but it varies by series, so always verify your specific model number first. For any keypad lock, how to change the door lock code also includes deleting any old user codes, not just the master. Previous residents may have set up codes for dog walkers or cleaners that still work even after you change your primary code.
For combination padlocks used on outbuildings, sheds, or gates, how to change the code on a combination lock usually requires opening it first with the current code, then holding a reset button or turning a reset lever on the back while dialing in your new sequence — again, exact steps are model-specific. If you've moved into a property and don't have the current code at all, that's a job for a professional. A trained locksmith can open the lock through legitimate means, verify your ownership, and either reset or replace the unit so you're not locked out of your own shed on day one.
## Mortise Lock Rekeying and Upgrades: The Right Hardware for Bergen County Homes
Hillsdale sits in a part of Bergen County where you'll find a genuinely mixed housing stock — Tudor-style homes near the train station, mid-century colonials on the quieter residential streets, and newer construction closer to Route 9W. Older homes in this area frequently have mortise locks on their front doors. These locks are well-built and durable, but the cylinder inside can be rekeyed just like any standard deadbolt, and an experienced locksmith will know exactly how to disassemble the mortise body without damaging the door or the escutcheon plate.
If you're upgrading, mortise lock installation is one of the most worthwhile investments you can make in a front door. The bolt engages the frame more deeply, the mechanism is harder to manipulate, and the overall assembly is more resistant to kick-in attacks than a standard cylindrical lock. Rapid Keys carries and installs a range of mortise lock hardware and can match finishes to your existing door hardware. Whether you need a straight rekey or a full mortise lock upgrade, call (201) 977-1100 and we'll come to you — no showroom trip required.
## What Determines the Cost — and How We Quote It
A common question we hear is some version of: how much does a locksmith cost, or what's the average price for this kind of work? Rather than give you a number that may not apply to your specific situation, here's how the quote is actually built. The type of lock matters most — a standard Kwikset deadbolt rekey takes less time and fewer parts than rekeying a multi-point mortise lock or programming a high-security smart lock. The number of locks on the property matters too; rekeying all exterior doors to the same key (called 'keying alike') is efficient and usually more cost-effective per lock when done in a single visit. Time of day is a factor: emergency locksmith calls at 2 a.m. carry a different rate than a scheduled afternoon appointment. Travel distance from our nearest available technician also plays a role, as does whether any parts need to be sourced for less common hardware.
What we commit to, every time: we confirm an exact, up-front price before any work begins. No surprises on the invoice. If you're asking how much an emergency locksmith should cost in NJ broadly — the honest answer is that it depends on those variables, and any reputable locksmith should be able to give you a firm number before they touch your door. We do exactly that.
## Why Rapid Keys Is Different — and the Services We Actually Provide
Some homeowners consider picking up a key-copying kiosk solution or a DIY rekeying kit from a hardware store. Those options can work for very basic scenarios, but they don't cover mortise locks, high-security cylinders, smart lock programming issues, or situations where you simply don't have the original key. A kiosk can copy a key you already have — it can't rekey your home, install a mortise lock, program a transponder key, or respond when you're locked out at midnight. Rapid Keys is a 24/7 mobile locksmith serving Hillsdale and surrounding Bergen County communities, which means a trained, insured technician comes to your door with the right tools — not a machine in a grocery store aisle.
Here is a specific, honest list of what our team handles every day: residential deadbolt rekeying, mortise lock rekeying and installation, door knob lock replacement, smart lock installation and code programming, high-security cylinder upgrades, master key system design, residential lockout response, commercial locksmith services for storefronts and office suites, commercial mortise lock service, access control system installation, keypad and keycard entry setup, safe opening and combination changes, mailbox lock replacement, garage door lock service, sliding door lock repair and reinforcement, window lock installation, car lockout service, automotive transponder key programming, car key duplication (including laser-cut keys), ignition switch repair and replacement, broken key extraction (door and ignition), emergency locksmith response any hour of the day or night, lock re-installation after door repair or replacement, padlock and gate lock service, and multi-point locking system service for steel and fiberglass doors. If your situation isn't on that list, call anyway — chances are we can help or can tell you immediately if it's outside our scope.
## When to Call Before You've Even Unpacked
The best time to rekey or change the locks at a new home is the same day you receive your keys at closing — ideally before you move boxes in. Once your furniture and valuables are inside, you naturally want the place secured. For new homeowners in Hillsdale, the sequence we recommend is: (1) take stock of all exterior entry points, including the back door, any side entry through a garage, and basement door locks that are often forgotten; (2) check whether any of those have smart locks or keypads that need code resets, not just mechanical rekeying; (3) have a single locksmith do all of them in one visit so you can also request that they be keyed alike, meaning one key opens everything. A mortise lock on the front, a standard deadbolt on the back, and a knob lock on the garage entry door can all be pinned to the same key cut — that's a clean, practical setup most homeowners appreciate once they stop juggling three different keys.
If you're reading this and already moved in but haven't dealt with the locks yet, it's not too late — it just became more urgent. And if you're a commercial tenant or business owner taking over a space near the Hillsdale downtown area, the same logic applies: previous tenants, cleaning crews, and contractors may all have keys. A commercial locksmith visit to rekey or upgrade your entry hardware is a standard step that any careful business operator takes on day one of a new lease. Rapid Keys handles both residential and commercial properties throughout Bergen County. Call (201) 977-1100 — we answer 24/7, and we can often schedule same-day service for new-move-in rekeying jobs.
Frequently asked questions
Is it better to rekey or fully change the locks when I move into a new home in Hillsdale?+
For most new homeowners, rekeying is the smarter first move — it locks out every key the previous owners ever had, costs less than new hardware, and takes less time. Full lock replacement makes sense when the existing hardware is damaged, outdated, or you want to upgrade to a higher-security option like a mortise lock or a smart deadbolt. A quick assessment by a trained locksmith will tell you which route is warranted for each door.
How do I change the code on my door lock if I have a smart lock or keypad I inherited from the previous owner?+
It depends on the brand and model. Most electronic keypad locks have a programming or reset button on the interior panel; you enter the existing master code (or a factory default if the previous code is unknown), then follow the prompts to set a new one. For a Honeywell door lock, how to change the code typically involves the Program button on the interior unit followed by a sequence of entries. The critical step most new owners miss is deleting all previously saved user codes — not just the master. If you don't have the current code and can't access the programming mode, a locksmith can help reset or replace the unit.
How much does a locksmith cost for rekeying or lock changes in NJ — what affects the price?+
There's no single flat rate because the quote depends on several real variables: the type of lock (a standard deadbolt rekeys faster than a mortise lock or smart lock), the number of locks being serviced, whether you need keying-alike across multiple doors, the time of day (emergency locksmith calls overnight carry different rates than daytime appointments), and travel distance. What doesn't change is our process — we confirm an exact price before any work begins. Call (201) 977-1100 for a no-obligation quote specific to your home and hardware.
Can a locksmith rekey a mortise lock, or does it have to be replaced entirely?+
Yes — a mortise lock cylinder can absolutely be rekeyed without replacing the entire lock body. The cylinder is removed from the mortise housing, repinned to match your new key, and reinstalled. This preserves the quality hardware already in your door, which is often worth keeping since mortise locks are more durable and secure than standard cylindrical locks. Only if the mechanism itself is damaged or the lock is a very outdated design that no longer fits the door properly would full replacement become necessary.
