Delaware's Deadbolt Installation Experts
If your home or business relies on a spring latch or a worn-out old deadbolt for security, you're more vulnerable than you might think. A quality deadbolt — properly selected and correctly installed — is one of the single most effective steps you can take to harden your doors against break-in attempts. Studies consistently show that most burglars look for quick, easy entry, and a strong deadbolt significantly raises that barrier.
1st Capital Locksmith provides professional deadbolt installation services for homes, apartments, rental properties, and commercial businesses throughout Delaware. We carry quality hardware from trusted brands and take the time to ensure every deadbolt is correctly fitted, aligned, and functioning smoothly before we leave your property.
Whether you need a basic single-cylinder deadbolt installed on a new door, a double-cylinder deadbolt added to a door with a window nearby, or a keypad or smart lock deadbolt for keyless entry convenience, we handle all types throughout Dover, Milford, Smyrna, Camden, Harrington, and all of Kent County, Delaware.
Types of Deadbolts We Install
Not all deadbolts are created equal. Here's a detailed breakdown of every deadbolt type we install and the situations where each one is the right fit. Not sure what you need? Call us and we'll walk you through it.
The single-cylinder deadbolt is the most widely used deadbolt type for residential exterior doors throughout Delaware. It operates with a keyed cylinder on the outside and a simple thumb-turn on the inside, allowing you to lock and unlock quickly from inside without a key — important for emergency exit. This is the correct choice for the vast majority of front doors, back doors, and side entry doors.
When selecting a single-cylinder deadbolt, quality and grade rating matter enormously. Cheap, builder-grade deadbolts sold at big-box stores are often ANSI Grade 3 — the lowest rating — and can be defeated surprisingly quickly. 1st Capital Locksmith recommends and installs ANSI Grade 1 deadbolts, which are the highest residential security rating and provide dramatically better resistance to picking, drilling, and forced entry.
We carry quality single-cylinder deadbolts in a range of finishes to match your existing hardware. Installation includes proper alignment with your door frame and strike plate reinforcement to ensure the bolt seats fully and the lock performs as designed.
A double-cylinder deadbolt requires a key to operate from both the outside and the inside. This makes it the right choice for doors that have glass panels, sidelights, or windows close enough that a burglar could break the glass, reach through, and turn a standard thumb-turn to unlock the door. With a double-cylinder lock, even getting a hand through the broken glass doesn't help — they still need the key.
Double-cylinder deadbolts come with an important safety consideration: in a fire or emergency, you need a key to exit. If you choose a double-cylinder deadbolt, we strongly recommend keeping a key hung near — but not reachable from — the door at all times, and making sure every household member knows where it is. Many homeowners use a key holder mounted a safe distance from the glass.
1st Capital Locksmith installs double-cylinder deadbolts throughout Delaware and will walk you through the safety guidelines before completing the installation. Your security and your family's safe exit in an emergency are both priorities we take seriously.
Keypad deadbolts combine the security of a traditional deadbolt with the convenience of keyless entry. You unlock your door by entering a PIN code — no key needed. This is a practical solution for families where kids come home from school before parents, for vacation rental properties, for landlords managing tenant access, or for anyone who's tired of fumbling for keys.
Modern keypad deadbolts offer features like auto-locking after a set time, multiple user codes (so you can give different codes to different people and delete them individually when needed), and backup key entry. Many models also have a built-in alarm that triggers after repeated incorrect code attempts — a valuable feature that adds an extra layer of security.
1st Capital Locksmith installs keypad deadbolts from trusted brands throughout Delaware. We handle everything from hardware selection through full installation and programming, and we make sure you're comfortable operating the lock before we leave.
Smart lock deadbolts take keyless entry to the next level. They connect via Bluetooth, Wi-Fi, or Z-Wave to your smartphone and smart home system, allowing you to lock and unlock your door remotely, receive notifications when your door is locked or unlocked, grant temporary access codes to guests or contractors, and check the status of your lock from anywhere.
Popular smart lock deadbolt brands like Schlage Encode, Kwikset Halo, Yale Assure, and August Smart Lock all offer excellent security alongside their smart features. Many also integrate with Amazon Alexa, Google Home, and Apple HomeKit ecosystems. The important thing is making sure the lock is professionally installed so it operates correctly and securely — a misaligned smart lock can fail to engage properly despite showing as "locked" on your phone.
We install smart lock deadbolts throughout Delaware and ensure correct alignment, proper door prep, and full function testing before completing the job. Whether you already have a brand in mind or need a recommendation, call us and we'll help you find the right fit.
For homeowners and property owners who want the highest level of door security available, we install ANSI Grade 1 high-security deadbolts. ANSI Grade 1 is the top residential security classification, tested to withstand at minimum 250,000 open/close cycles and significant impact force. Brands like Schlage B60N, Kwikset 980, and Medeco Maxum are examples of Grade 1 hardware that deliver real, measurable protection.
High-security deadbolts often feature hardened steel bolts, anti-drill pins, anti-pick security pins, and reinforced housings that make them dramatically more resistant to the most common forms of physical attack. Combined with a properly reinforced strike plate and long screws that anchor into the door frame's structural wood, a Grade 1 deadbolt installation represents the standard we recommend for all primary entry doors.
If you're upgrading from a builder-grade lock or have concerns about the security of your property, this is the installation we'd recommend. 1st Capital Locksmith carries and installs Grade 1 deadbolts throughout Delaware — call us to discuss the right option for your specific door and situation.
If your existing deadbolt is stiff, difficult to turn, loose in the door, damaged from a break-in attempt, or simply old and worn out, it's time for a replacement. A deadbolt that's struggling to operate reliably isn't providing the protection you're counting on — and a failing lock has a way of completely giving out at the most inconvenient possible moment.
1st Capital Locksmith handles deadbolt replacements throughout Delaware on the same visit. We remove the old hardware, inspect the door and frame for any damage or alignment issues that need to be addressed, install the new deadbolt correctly, and test the operation before we leave. In most cases a standard deadbolt replacement fits into an existing door prep hole with no additional drilling required.
Replacing an outdated or damaged deadbolt is also a great opportunity to upgrade your security level at the same time. If you're currently running a builder-grade lock, a replacement with a quality Grade 1 deadbolt makes a significant difference for a reasonable cost.
Here's a security fact that surprises many homeowners: even the best deadbolt in the world can fail if it's secured with a weak strike plate. The strike plate is the metal piece mounted on the door frame that receives the deadbolt. Most builder-installed strike plates are thin, flimsy, and held in place with short 3/4-inch screws that only go into the door casing — not the structural framing behind it. A strong kick can split the door frame around these small screws in seconds.
Proper deadbolt installation always includes reinforcing the strike plate with heavy-duty hardware and 3-inch screws that penetrate through the door casing and deep into the jack stud behind it. This dramatically increases the kick resistance of your door — some studies suggest it can increase resistance to forced entry by 10x or more compared to a standard installation.
Every deadbolt installation we perform at 1st Capital Locksmith includes strike plate inspection and reinforcement as part of the job. We don't install a lock without ensuring the frame is equally secure — because a chain is only as strong as its weakest link.

Customer Reviews
"We just moved into our house and wanted quality deadbolts on all three exterior doors. 1st Capital Locksmith came out the next day, installed Grade 1 Schlage deadbolts on every door, and reinforced the strike plates too. The technician explained everything he was doing and why. Great service — we feel so much more secure now."

Deadbolt Installation — Dover, DE
"I had a cheap builder-grade deadbolt on my front door for years and finally decided to upgrade. The locksmith from 1st Capital told me about the difference in grades, recommended a Schlage Grade 1, and had it installed within the hour. Night and day difference in how solid it feels. Should have done this years ago."
James F.
Deadbolt Upgrade — Smyrna, DE
"I wanted a keypad deadbolt for my back door so my kids could get in without a key after school. 1st Capital installed it perfectly, programmed two codes, and showed my kids how to use it before they left. Everything worked great from day one. Very professional service and a fair price."
Tonya M.
Keypad Deadbolt Installation — Milford, DE
"My front door has a large glass window right next to the knob and I was always worried about it. The locksmith explained why I needed a double-cylinder deadbolt for that door and went over the fire safety considerations too. He installed it the same day and it gives me so much more peace of mind now."

"Had 1st Capital install a smart deadbolt on my front door. They helped me pick the right model that works with my Alexa setup, installed it, and made sure everything was paired before leaving. Fantastic experience — I can lock and unlock my door from anywhere now. Highly recommend them."

"I own a small rental property and needed new deadbolts installed after a tenant moved out. 1st Capital came out quickly, installed two new deadbolts, and rekeyed them so I have fresh keys for the new tenant. Fast, professional, and reasonably priced. I'll definitely use them again for my other property."

FAQ
Common questions about deadbolt installation, types, grades, and costs in Delaware.
Cost depends on the deadbolt type (standard, keypad, or smart lock), the number of doors, and whether new door boring is required. We provide a clear upfront quote before any work begins. Call (302) 735-0050 for a fast estimate specific to your situation.
For most homes, an ANSI Grade 1 single-cylinder deadbolt from a brand like Schlage or Kwikset is the best choice. Grade 1 is the highest residential security classification and offers significantly better resistance to picking, drilling, and forced entry compared to the cheaper Grade 3 locks often installed by builders.
Yes. If your door doesn't have an existing deadbolt hole, we can bore a new hole on-site using professional door prep equipment. We'll assess your door first and confirm it can accommodate a standard deadbolt before drilling.
A single-cylinder deadbolt uses a key outside and a thumb-turn inside — the standard for most exterior doors. A double-cylinder deadbolt requires a key on both sides, which is recommended for doors with glass panels nearby. Double-cylinder locks require extra fire safety precautions since you need a key to exit — we'll go over this during installation.
Yes. We install keypad deadbolts, Bluetooth smart locks, Wi-Fi smart locks, and Z-Wave smart locks throughout Delaware. We handle the full installation and programming on-site and make sure everything is working correctly before we leave.
A standard deadbolt installation on a prepared door typically takes 20–30 minutes per lock. If door boring is required, add some time for the prep work. Smart lock installation and programming takes a bit longer depending on the model. We handle everything on-site at your property.
At minimum, you should have all locks rekeyed when you move in so previous keys no longer work. If the existing deadbolts are low-quality builder-grade hardware, upgrading to Grade 1 deadbolts at the same time is a smart investment in your family's security. We can rekey your existing locks, replace them, or do both in a single visit.
Yes. We install commercial-grade deadbolts for offices, retail spaces, warehouses, and other commercial properties throughout Delaware. Commercial applications may require heavier-duty hardware than residential — call us and we'll recommend the right solution.
