Just Moved In? A Rekey Checklist for Your New Home

Rekeying is the process of changing the internal pin configuration of a lock cylinder so that the old key no longer works and a new one does. It is not the same as replacing the entire lockset, and in most situations you do not need a full replacement. The hardware stays in place; only the tumblers inside the cylinder change. This matters because the Greenville area has a significant stock of older homes — some dating to the early 20th century — many of which carry original or period-appropriate mortise lock hardware. A corbin antique mortise lock, for example, is a beautiful piece of engineering that is still perfectly functional and worth preserving. Rekeying the cylinder inside that mortise lock body keeps the character of the door intact while completely resetting who has access. A skilled locksmith knows how to change the cylinder in a door lock of this type without damaging the antique case, which is a task that genuinely requires hands-on experience rather than a weekend tutorial.

Full lock replacement does make sense in specific scenarios: the existing hardware is damaged beyond serviceable condition, you are upgrading to a higher-security grade, or you are adding a smart lock with keypad or app control. In those cases, understanding how to install a mortise lock in a new door — including routing the pocket correctly and aligning the strike plate — becomes part of the job. Our team handles both rekeying and full mortise lock installation, so we can give you an honest recommendation on which path makes sense for each door in your home rather than defaulting to the more expensive option.

Start at the front door and work systematically around the perimeter. Front entry door: rekey or cylinder change, verify the deadbolt and the door knob lock are keyed alike if that is your preference, and inspect the strike plate for proper depth and screw length. Back and side doors: these are statistically the most common points of unauthorized entry, yet they are the ones new homeowners most often forget. Garage entry door: if the door from your garage into the home does not have a quality deadbolt, this is the moment to add one — it is your second front door. Sliding glass doors: these do not rekey in the traditional sense, but the locking bar, security pins, and anti-lift hardware should all be inspected and adjusted. Basement or cellar entry: older Greenville homes frequently have original cellar doors with lever or mortise-style hardware that has been rekeyed a dozen times by a dozen owners. A professional assessment here is worth every minute. Interior locks on a home office, medicine cabinet, or gun safe: these have different cylinder types and should not be overlooked if sensitive items are involved.

Once the perimeter is covered, make a note of any outbuildings — a detached garage, garden shed, or pool house. If those structures are on your property, their locks tie back to your security profile too. Finally, if the home has a security system with a smart door lock — whether it uses a proprietary app or a Z-Wave hub — you will want to reset the access codes, update any paired devices, and check that the batteries are freshly installed. Knowing how to change batteries in an August lock, for instance, typically involves removing the interior mount and swapping in four AA batteries, then confirming the lock re-syncs with your app. Similarly, if your home uses an ADT-integrated smart lock, understanding how to change batteries in that ADT door lock before the low-battery alert interrupts your first night of sleep is a small but genuinely useful bit of prep. Our team can walk you through device pairing and code resets as part of a full move-in locksmith appointment.

Mortise lock is a term that confuses a lot of buyers because it covers a range of hardware that looks and operates differently from the cylindrical locksets most people grew up with. The mortise lock body — the rectangular metal case — is set into a pocket (the mortise) cut into the edge of the door. It contains the latch, the deadbolt throw, and sometimes a chain or nightlatch mechanism all in one unit. The cylinder, sometimes called the plug, is the separate piece that your key enters; it can be removed and rekeyed or swapped independently of the main body. Older American manufacturers like Corbin produced mortise lock hardware that is still widely installed in historic Delaware properties, and the corbin mortise lock found in antique locks and keys collections is a recognizable piece of that era. These cylinders use a different pin stack geometry than modern Kwikset or Schlage keyways, so not every locksmith carries the right blanks — confirm your provider has experience with period hardware before booking.

Beyond mortise locks, your new home may have cylindrical locksets (the most common modern type), rim locks (surface-mounted, often on older interior doors), deadlatches, or lever-handle commercial-grade locksets if the property was previously used as a rental with frequent tenant turnover. Locksmith specializations exist precisely because these systems are not interchangeable. A residential locksmith who focuses on mortise lock rekeying, antique hardware, and smart lock integration has a different toolkit than a commercial locksmith who works primarily on panic bars, electric strikes, and access control panels. Reliable Wilmington Locksmith covers both ends of that spectrum, which matters for Greenville homeowners whose properties sometimes blend original historic hardware with contemporary security technology.

Modern homes — and increasingly, resold homes — come with smart lock technology already installed. After closing, you need to assume that the previous owner's phone, codes, and paired devices still have access until you deliberately reset everything. A trained locksmith can assist with factory resets on most major smart lock platforms, re-pair the lock to your own hub or app, and verify that the mechanical backup cylinder is also rekeyed. Many homeowners also ask: can a locksmith program my key fob? The answer depends on the fob type. Automotive key fobs for the garage door opener are typically programmed through the vehicle's onboard system or a dedicated programmer. Smart home access fobs tied to a Z-Wave or Zigbee hub can usually be reset and re-enrolled during the same appointment as your lock rekeying. If you have moved into a home with a car stored on the property — or if you are dealing with a detached garage that uses a coded remote — our team can assess and address those access points as well.

This is also a good moment to think about emergency locksmith access planning for your new home. Put a spare key with a trusted neighbor or in a secure key lockbox mounted somewhere non-obvious on the property. Know which windows open from the outside as a legitimate backup entry (and consider whether that is a vulnerability you want to address). Having a plan before you need it means that the first time you lock yourself out in Greenville, you have options that do not involve waiting on the sidewalk at midnight. If you do find yourself in that situation, our 24/7 emergency locksmith service covers the entire Greenville and Wilmington area — call (704) 850-6756 and a mobile technician will be dispatched to your address.

If you have recently relocated from outside the United States, it is worth understanding that locksmith regulation varies significantly by country — and even by state within the U.S. In the United Kingdom, locksmith work is governed by a combination of voluntary trade bodies and consumer protection law; practitioners are expected to follow a code of practice and many pursue membership in recognized industry associations that set technical benchmarks. Regulation by country shapes not just who can call themselves a locksmith, but what training pathways exist and how consumer disputes are handled. In the United States, locksmith licensing requirements vary by state. Delaware does not currently require a state-issued locksmith license, which means the barrier to entry is lower than in states like Virginia or Maryland — making it even more important that you choose a provider based on verifiable experience, insurance, and a transparent quoting process rather than assuming a license guarantees quality.

What this means practically for a Greenville homeowner: ask your locksmith how long they have been working with the specific hardware types in your home, whether they carry insurance (we are insured), and whether they provide a confirmed price before any work begins. At Reliable Wilmington Locksmith, we assess the lock type, door configuration, any specialty hardware like a mortise lock with antique cylinder, the time of day, and travel distance to your address — all of those factors shape the final quote, which we confirm with you up front before a single tool comes out of the bag. There are no surprise charges after the job is done. If you are ready to schedule your move-in rekey or want to talk through what your specific doors need, call us at (704) 850-6756 — we are available around the clock, every day of the year.
