Moving into a new home along Philadelphia Pike or settling into one of Claymont's quiet residential streets is exciting — but that excitement can fade fast if you realize you have no idea who else might have a key to your front door. Previous owners, contractors, real estate agents, neighbors who were trusted with a spare — the list of people who could still walk in is longer than most new homeowners want to think about. The good news is you have two solid options: rekey your existing locks or replace them entirely. Knowing which one fits your situation can save you real headaches down the road.
This guide breaks down exactly what rekeying involves, when it makes more sense than buying new hardware, and when a full lock replacement is the smarter call. We'll also cover mortise locks, smart locks, and the scenarios every new Claymont homeowner should think through before their first night in the house.
## Rekeying vs. Replacing: Understanding the Core Difference
When a locksmith rekeyes a lock, they disassemble the lock cylinder and swap out the small internal pins — called key pins and driver pins — so that the old key no longer works and a freshly cut key does. The hardware itself (the lock body, the bolt, the strike plate) stays exactly where it is. This is why rekeying is typically less involved than a full replacement: you're changing the secret, not the door. So if you've ever asked yourself 'can you rekey a lock without touching the rest of the door?' — yes, in most cases you absolutely can.
Replacing a lock, on the other hand, means removing the entire lockset or mortise lock assembly and installing new hardware. This makes sense when the existing hardware is worn, outdated, damaged, or simply not up to the security standard you want for your new home. A full replacement is also the right move when you're upgrading from a basic door knob lock to a deadbolt, or when you want to introduce a smart lock system. The decision between the two comes down to the condition and quality of what's already installed — and that's something a trained locksmith can assess on the spot.
## How Do You Rekey a Door Lock — and Can You Rekey Any Lock?
The process of rekeying a door lock follows a consistent set of steps. A locksmith removes the lock cylinder from the door, uses a specialized follower tool to push out the plug (the rotating part you insert the key into), and then removes the existing key pins from the plug. New pins of different heights are inserted to match a new key blank, the plug is reassembled, and the cylinder is reinstalled. The whole job on a standard deadbolt or door knob lock typically takes a professional only a few minutes per lock — but doing it correctly requires the right pinning kit, follower tool, and familiarity with each brand's cylinder design.
Can you rekey any lock? The honest answer is: most pin-tumbler locks can be rekeyed, which covers the vast majority of residential deadbolts and knob locks from brands like Schlage and Kwikset. Mortise locks — the longer, rectangular lock bodies common in older Claymont homes and in commercial properties — can also be rekeyed, though their cylinders require a bit more care to remove and reassemble. There are some exceptions: certain high-security locks use proprietary keyways that can only be rekeyed by a locksmith working with that manufacturer's tooling, and some older or worn cylinders are better replaced than rekeyed. A quick inspection tells the story.
## When Replacement Beats Rekeying: Mortise Locks, Smart Locks, and Worn Hardware
If your new home has an aging mortise lock with a loose chassis or a worn bolt mechanism, rekeying the cylinder is only half the solution — the underlying hardware still poses a security risk. Mortise locks are a specialty area for a skilled locksmith because their internal components are more complex than a standard cylindrical lock. When we assess a mortise lock, we're looking at the case, the spindle, the cam, and the cylinder together. If the case is damaged or the bolt doesn't throw cleanly, replacement of the full mortise unit is the right call, and it's an upgrade worth making. A quality mortise lock on your front door is a meaningful security improvement over a basic door knob lock.
Smart locks are another category where the rekey question gets interesting. Can you rekey a smart lock? Some models that use a physical key override alongside their electronic mechanism can be rekeyed just like a traditional cylinder — a locksmith simply repins the backup key cylinder. Others are entirely keyless and 'rekeying' means resetting user codes rather than any physical pin change. Can you rekey a smart lock without the original key? If the lock has a physical cylinder component, yes — a trained locksmith can repin it using a blank without needing the old key, since the cylinder is disassembled directly. If you're moving into a home with a smart lock already installed, call us and we'll identify the model and walk you through the right approach. Reach us any time at (631) 380-4138.
## Keying Alike: Can You Rekey a Lock to Match an Existing Key?
One of the most practical — and underused — services for new homeowners is keying alike, also called master keying at the residential level. Can you rekey a lock to match an existing key? Yes, as long as the locks share a compatible keyway (for example, both are Kwikset KW1 or both are Schlage C keyway), a locksmith can repin each cylinder to match a single key you already own. This means your front door, back door, side entry, and garage entry can all operate on one key. For a home with multiple entry points — something common in the older two- and three-story homes near Manor Avenue in Claymont — this is a convenience that also reduces the number of keys floating around.
Do you need to rekey a new lock that comes fresh from the box? Here's something many homeowners don't know: several lock manufacturers ship their products keyed to a small set of common factory codes to simplify retail packaging. That means a brand-new lock from a hardware store could theoretically be opened by someone with the same factory key. Having a locksmith rekey a new lock upon installation — or having us key it to match your other entry points — ensures you start with a truly unique key combination from day one.
## Making the Call: A Practical Checklist for New Claymont Homeowners
Before you decide, run through these checkpoints. First, inspect the hardware: do the locks operate smoothly, does the deadbolt throw fully, is there play in the door knob lock cylinder? If anything feels loose, stiff, or uncertain, lean toward replacement. Second, know your history: did the previous owner provide all keys, or is the key history unknown? Unknown history means rekeying is a minimum step — not optional. Third, consider your security goals: are you staying with standard locks or upgrading to a mortise lock or smart lock system? Upgrades mean replacement. Fourth, think about keying alike: do you want one key for every door? This can be factored into a rekey job from the start. Fifth, check for an emergency locksmith need: if you've lost keys on moving day or discovered a lock that won't function, that's a situation our 24/7 mobile team handles regularly throughout the Claymont area.
Pricing for rekeying and lock replacement depends on several factors: the type and brand of lock (a standard door knob lock differs from a commercial-grade mortise lock), the number of locks being serviced, the time of day, travel distance, and whether new parts or hardware are needed. We confirm an exact price before any work begins — no surprises when the job is done. If you're ready to secure your new home, call (631) 380-4138 and we'll come to you, any time of day or night.
Frequently asked questions
How much is the average locksmith charge for rekeying a home after moving in?+
There's no single flat rate because the final quote depends on several variables: the type of locks being rekeyed (a standard door knob lock versus a mortise lock), how many cylinders are on the property, the time of day the service is requested, travel distance to your Claymont address, and whether any replacement parts are needed. What we always do is confirm an exact price up front before we start — so you know the full cost before we touch a single lock.
What is the most common locksmith task for new homeowners?+
Rekeying entry locks is by far the most frequent request we handle from people who've just moved into a home. It's a straightforward security measure that ensures previous keyholders — former owners, contractors, real estate contacts — can no longer use their old keys. Close behind that are lock replacements when existing hardware is worn or outdated, and smart lock installations for homeowners who want keypad or app-based access on their new property.
What locks can locksmiths not open?+
A skilled locksmith can open the vast majority of residential and commercial locks through legitimate, non-destructive methods — picking, bypass techniques appropriate to the lock type, or decoding. However, some very high-security locks with anti-pick pins, hardened steel inserts, and restricted keyways are specifically engineered to resist standard entry techniques, meaning even experienced locksmiths may need to drill as a last resort (and then replace the cylinder). Certain electronic smart locks that have lost power or have a malfunctioning circuit board can also present challenges that go beyond mechanical lock work. In those cases, the solution is often replacement of the electronic module rather than traditional entry.
Should I tip my locksmith?+
Tipping is entirely at your discretion and is never expected or factored into our pricing. If a job was handled quickly, professionally, and at an inconvenient hour — like a late-night emergency locksmith call — some customers choose to tip as a gesture of appreciation, and that's always genuinely welcomed. That said, our team's goal is simply to get you taken care of at the price we quoted, with no pressure around gratuity.
