Delaware's Lock Change Experts
Sometimes rekeying isn't enough. When your locks are old, worn, damaged, or simply not up to the security standard your property deserves, changing them entirely is the right call. A fresh set of quality locks — properly selected and correctly installed — is one of the most reliable ways to take control of who has access to your home or business.
1st Capital Locksmith provides professional lock change service for residential and commercial properties throughout Delaware. We carry a selection of quality replacement hardware and handle the full job on-site — removing old locks, fitting new hardware, testing operation, and leaving your property more secure than we found it. We also make sure the new lock fits your door correctly and that the strike plate is properly reinforced.
Whether you need one door lock changed or every exterior lock on your property replaced, we serve homeowners, renters, landlords, and business owners throughout Dover, Milford, Smyrna, Camden, Harrington, and all of Kent County, Delaware.
Lock Change Situations We Handle
There are many reasons to change your locks — and not all of them involve an emergency. Here's a detailed look at the most common lock change situations we handle for residents and businesses throughout Delaware.
Moving into a new home is one of the most common — and most important — reasons to change your locks. The previous owners, former tenants, real estate agents, contractors, cleaning crews, and anyone else who ever had a key to that property could still have a working copy. You have no way of knowing how many keys are out there, and the only way to truly take control of who can enter your home is to start fresh with new hardware.
1st Capital Locksmith helps new homeowners and renters throughout Delaware get their new homes secured properly. In many cases, rekeying the existing locks is a fast and cost-effective solution if the hardware is in good condition. But if the locks are old, worn, low-quality builder-grade hardware, or if you simply want the peace of mind that comes with brand-new locks, we can replace every exterior lock on your home in a single visit.
We recommend scheduling your lock change the same day as your move-in, or even before you bring in your furniture and belongings. It's a small investment that pays for itself in the security and peace of mind it provides from your very first night in a new home.
Losing your keys — or having them stolen — creates an immediate security concern. If your keys had any kind of identifying information attached to them (a tag with your address, a keychain from a local business, or anything that could connect the key to your home), you should act quickly. Even if there's no obvious identification, the possibility that someone has both a key and the motivation to use it is a real risk that isn't worth leaving unaddressed.
Rekeying is often the fastest and most affordable option in a lost key situation — it prevents the lost key from working without replacing the entire lock hardware. However, if your current locks are already past their prime, this is a good opportunity to upgrade to better hardware at the same time. 1st Capital Locksmith carries replacement hardware and can do either on the same visit.
Don't let a lost key sit as an open security question. Call us and we'll get your home re-secured quickly throughout Delaware, with upfront pricing before we start.
Every responsible landlord changes or rekeys the locks between tenants — full stop. No matter how well a tenancy went, the outgoing tenant may have made copies of the keys that were never returned, and those copies are now in the hands of people you don't know. Protecting your next tenant — and your property — means ensuring no previous key will work when a new tenant moves in.
1st Capital Locksmith works with landlords and property managers throughout Delaware to handle lock changes at tenant turnover, after lease disputes, and in situations where a tenant failed to return all keys at move-out. We're efficient, reliable, and understand the time pressure that comes with tenant turnovers — we work around your scheduling to get the property re-secured between occupancies.
If you manage multiple rental properties in Kent County, give us a call. We offer consistent, reliable service across your portfolio and can build a working relationship that makes lock changes a seamless part of your turnover process.
After a break-in, getting your property re-secured is the immediate priority. Any lock that was attacked — whether by kicking, picking, drilling, or prying — needs to be assessed and in most cases replaced. A lock that has been forcibly compromised may appear to function normally while having significantly reduced structural integrity and security capability. You can't rely on it.
Beyond just replacing the damaged hardware, a break-in is also a clear signal to review the overall quality of every lock on your property. Burglars typically target the easiest entry point — but they'll move to the next easiest if the first fails. Upgrading from builder-grade hardware to quality Grade 1 deadbolts across all entry points is a smart response to a break-in.
1st Capital Locksmith responds to post-break-in lock change calls throughout Delaware. We also assess and reinforce door frames and strike plates that may have been weakened during the forced entry — because a strong lock on a weakened frame is only as good as the frame. Call (302) 735-0050 and we'll get there as quickly as possible.
Many homes in Delaware — particularly those built in the last decade or two — came with builder-grade locks as standard. These are typically ANSI Grade 3 hardware: the lowest security classification, designed to meet a minimum cost target rather than a maximum security standard. They're often straightforward to defeat, and they wear out faster than quality hardware.
Upgrading to ANSI Grade 1 deadbolts and quality entry hardware is one of the highest-return security investments you can make in your home. The price difference between builder-grade and Grade 1 hardware is modest, but the difference in forced-entry resistance, pick resistance, and overall durability is significant. Many homeowners who have upgraded describe the change as noticeable — the hardware simply feels and operates like a different category of product.
1st Capital Locksmith advises on and installs security upgrade lock replacements for homes and businesses throughout Delaware. Whether you want to upgrade one door or every lock on the property, we'll help you choose the right hardware for your security goals and budget.
Commercial properties have their own distinct lock change needs — employee turnover, management changes, security audits, lease transitions, and hardware that's reached the end of its service life are all common triggers. Keeping control of who has access to your business is an ongoing responsibility, and lock changes are a key part of that.
1st Capital Locksmith changes commercial door locks for offices, retail stores, restaurants, warehouses, medical practices, and other business properties throughout Delaware. We carry commercial-grade hardware and can advise on the best options for your specific access control needs — from standard keyed deadbolts to keypad entry systems to locks that integrate with master key systems.
We understand that commercial lock work needs to happen on your schedule. We'll work around your business hours, coordinate with your facilities team, and complete the work with minimal disruption to your operations. Call us at (302) 735-0050 to discuss your commercial lock change needs.
This is one of the most common questions we get, and the honest answer is: it depends on your situation. Rekeying is faster and less expensive — it changes the internal pin configuration of your existing lock so all previous keys stop working, while keeping the same hardware in place. It's the right choice when your locks are in good condition and you simply need to void old keys.
A full lock change makes more sense when: your existing hardware is damaged, worn out, or of poor quality; you want to upgrade to a higher security grade; you want a fundamentally different type of lock (like switching from a knob to a deadbolt, or adding a keypad); or when you want the complete assurance that every component is brand new. Lock changes cost more than rekeying, but they deliver a fully reset security baseline.
Not sure which you need? Call us at (302) 735-0050 and describe your situation. We'll give you an honest recommendation without pushing you toward the more expensive option unless it's genuinely the right call for your circumstances.

Customer Reviews
"Just bought my first home and had 1st Capital come out and change all the exterior locks the day we moved in. The locksmith was professional, quick, and explained the difference in lock grades — we ended up upgrading to Grade 1 deadbolts on all three doors. Couldn't be happier with the peace of mind it gives us."
Jennifer & Tom K.
New Home Lock Change — Dover, DE
"My purse was stolen with my keys inside. Called 1st Capital and they came within two hours and changed both exterior door locks. Fast response, fair price, and the new locks are noticeably better quality than what I had before. Highly recommend them for anyone in a similar situation."

Richard A.
Rental Property Lock Change — Milford, DE
"Had a break-in attempt at my house — they didn't get in but the front door lock was damaged. Called 1st Capital the next morning and they came that afternoon. Replaced the lock, reinforced the strike plate, and put on a much better deadbolt than what I had. Very professional and thorough."
Cynthia L.
Post Break-In Lock Change — Camden, DE
"Changed all the locks in our office after an employee left on bad terms and didn't return their keys. 1st Capital worked around our schedule and had everything done before close of business. New locks are solid quality and all staff have new keys. Great experience — will definitely use them again."
Sandra M.
Commercial Lock Change — Dover, DE
"We'd been meaning to upgrade the old locks on our house for years. Finally called 1st Capital and it was the easiest experience. The technician came out, showed us our hardware options, and replaced all three exterior locks with Grade 1 deadbolts. The new locks feel like a completely different category. Very satisfied."

FAQ
Common questions about lock changes in Delaware — costs, timing, and when to change vs. rekey.
The cost depends on the type of lock, the brand of replacement hardware, and the number of doors. We provide a clear upfront quote before starting any work. Call (302) 735-0050 for a fast, no-obligation estimate based on your specific situation.
Rekeying reconfigures the internal pins of your existing lock so old keys stop working — it's faster and less expensive, and the hardware stays in place. A lock change replaces the entire lock with new hardware. Lock change is the right choice when hardware is damaged, worn out, low quality, or when you want a different type of lock entirely.
Change your locks when: the hardware is damaged or worn; you want to upgrade to a higher security grade; you want a different lock type (like a keypad or deadbolt); after a break-in; or when the existing lock is simply too old for reliable performance. When in doubt, call us and we'll give you an honest recommendation.
In most cases, yes. Our mobile locksmiths carry common replacement hardware and can often complete a lock change on the same day throughout Delaware. Call (302) 735-0050 and we'll confirm our availability for your location.
Yes. We regularly work with landlords and property managers throughout Delaware. We handle lock changes at tenant turnover, after lease disputes, and when tenants fail to return all keys. We can efficiently service multiple properties and work around your turnover schedule.
Absolutely. We change commercial door locks for offices, retail stores, warehouses, and other business properties throughout Delaware. We carry commercial-grade hardware and can schedule work around your business hours to minimize disruption.
It depends on the reason for the change. If it's a security concern (lost keys, break-in, tenant change), you should change all exterior locks since any of them could be compromised. If it's a hardware quality issue on one specific lock, just that one may be fine. We'll advise you based on your situation.
We carry lock hardware in the most common finishes — satin nickel, oil-rubbed bronze, polished brass, and matte black. Let us know your preference when you call and we'll do our best to match your existing hardware aesthetics.
