In 2026, the national average cost for deadbolt installation runs $175 per lock. Most homeowners pay $70 to $300 per lock, with the spread driven by lock type, door material, and labor. Standard deadbolts sit at the lower end, while smart and high-security models push costs higher.
The number of deadbolts you install is a major driver of your total cost, with per-lock prices ranging from $70 to $300 for most residential projects. Each additional lock adds hardware and labor expenses, though many professionals offer per-unit discounts when installing several locks in a single visit. Costs vary depending on the number of doors and property type, as shown in the breakdown below.
A single deadbolt installation typically carries a higher per-unit cost because minimum service fees apply, while whole-home or multi-unit projects bring that per-lock rate down. Costs depend on how many locks you need and the scope of the project, as shown in the breakdown below.
| Number of Deadbolts | Description | Average Cost per Lock in 2026 | Total Cost in 2026 |
|---|---|---|---|
| 1 | Single door | $100–$300 | $100–$300 |
| 2–3 | Front and back doors | $70–$250 | $180–$750 |
| 4–6 | Whole home upgrade | $70–$200 | $320–$1,200 |
| 10+ | Multi-unit property | $70–$180 | $700–$1,800 |
Standard doors keep installation straightforward and predictable, but oversized, thick, or specialty doors, such as metal or custom wood, can increase labor time and require special hardware. Doors that are not pre-drilled or that need reinforcement add to both labor and material costs, and non-standard doors may also require custom-fit deadbolts that raise the overall price further.
The type of deadbolt you choose is one of the most significant factors in your total installation cost, with materials ranging from $25 for a basic single-cylinder lock to $350 for a smart model. Single-cylinder deadbolts are the most common and affordable option, while double-cylinder models and commercial-grade locks cost more due to added security features. Keyless mechanical and smart deadbolts offer convenience at a premium, and costs vary by type as shown in the breakdown below.
| Deadbolt Type | Description | Average Cost (Materials Only) in 2026 |
|---|---|---|
| Single-cylinder | Key outside, thumb turn inside | $25–$60 |
| Double-cylinder | Key both sides | $35–$80 |
| Smart deadbolt | Electronic, Wi-Fi/Bluetooth enabled | $100–$350 |
| High-security/commercial | Reinforced, drill-resistant | $80–$200 |
| Keyless mechanical | Code entry, no electronics | $60–$150 |
Replacing an existing deadbolt costs less than a new installation because the holes and strike plates are already in place, while new installations on doors without a prior deadbolt require drilling and additional labor that raise the total. If your door or frame needs modification, costs increase further, so checking compatibility with your current hardware before starting is a practical way to avoid unexpected charges.
Premium deadbolt brands made from solid brass, stainless steel, or reinforced alloys cost more upfront but deliver better durability, stronger security, and longer-lasting performance. Budget locks use lighter materials that wear out faster, which can lead to higher replacement costs over time, making a reputable brand with a solid warranty the smarter long-term investment.
Where you live and where the deadbolt is installed within your home both influence your final price, with labor rates, material costs, and local demand all playing a role.
Deadbolt installation costs vary by region, with urban areas and high-cost-of-living cities carrying higher labor rates while rural locations may offer lower prices but add travel fees. Local demand and the availability of skilled deadbolt installation professionals also influence what you pay in any given market.
A main entry door is the most common and straightforward installation, while interior, garage, basement, or outbuilding doors may require additional reinforcement or specialty hardware that adds to the cost. Hard-to-access locations, multi-story homes, and multi-unit buildings increase labor time and overall price, and unexpected obstacles such as reinforced frames or old hardware can result in additional charges.
Several factors shape your total deadbolt installation cost, and understanding them helps you plan your project and set a realistic budget.
Deadbolt installation is handled by locksmiths, handypersons, and security specialists, with locksmiths charge typically higher rates due to their expertise and licensing. Labor is billed per lock, per hour, or as a flat rate, with minimum service fees of $50 to $100 and hourly rates of $50 to $150 depending on location and expertise. Emergency or after-hours installation adds a premium of 20% to 50% on top of regular rates.
Permits for deadbolt installation are rarely required in residential settings, though some multi-family or commercial buildings have specific regulations that make them necessary, with permit costs running $25 to $100 when required. Always check with your local building department or HOA before starting work to confirm whether a permit applies to your project.
Advanced features such as smart lock integration, Wi-Fi or Bluetooth connectivity, keypads, and biometric access add $30 to $200 per lock to your project cost depending on the technology. Reinforced strike plates, anti-drill hardware, and decorative finishes are also available for an additional fee.
There are several additional factors that can influence the cost of deadbolt installation, including:
Complexity of installation: Retrofitting, drilling new holes, or modifying doors and frames increases labor time and cost.
Accessibility: Hard-to-reach doors, upper floors, or tight spaces may require additional labor.
Site preparation: Removing old locks, patching holes, or repairing damaged doors can increase your total cost.
Delivery or travel fees: Remote locations may incur extra charges.
Post-installation cleanup: Debris removal, if not included, may be an additional fee.
Design or consultation: Custom security planning or consultation services can increase costs.
Inspection: Some HOAs or local codes require post-installation inspection, which may have a small fee.
Beyond the installation itself, a few additional costs are worth factoring into your deadbolt budget before you finalize your plans.
Most deadbolts include a manufacturer's warranty covering hardware defects for one to 10 years, and some installers also offer a one-year labor warranty on their workmanship. Extended warranty plans are available for an additional fee, though they are generally unnecessary for standard residential installations.
Smart deadbolts require battery replacements every six to 12 months, and some models also charge connectivity or app subscription fees of $2 to $10 per month. Traditional deadbolts carry no ongoing operating costs.
Routine deadbolt maintenance involves lubricating the lock, tightening screws, and checking alignment annually, with professional servicing or rekeying averaging $20 to $50 per lock. High-quality deadbolts last 5 to 15 years, while lower-end models may need replacement sooner.
Sales tax on deadbolt hardware and installation services varies by state and locality, adding 5% to 10% to your total bill, so confirm the applicable rate in your area when setting your budget.
Installing deadbolts can lower your homeowners' insurance premium by 2% to 5%, as insurers view upgraded locks as a security improvement. Ask your provider about documentation or certification requirements to qualify for discounts.
You can install a deadbolt yourself or hire a professional, and the right choice depends on your skills, tools, and comfort level with home improvement projects.
To install a deadbolt yourself, you'll pay for the deadbolt hardware ($25 to $350), plus any tools you do not already own. Essential tools, such as a drill, hole saw, screwdriver, and chisel, can cost between $30 and $100 when purchased new. Expect to spend one to two hours per lock as a first-timer. DIY saves on labor, but it also risks improper installation, which can compromise security or void warranties.
Hiring a professional locksmith near you means paying higher upfront costs, but you benefit from their expertise, proper installation, and warranty coverage. Most professionals charge $50 to $150 per lock for labor, plus the cost of the lock itself. DIY is best for basic replacements on standard doors, while a pro is recommended for smart locks, new installations, or specialty doors.
Here is how DIY and professional deadbolt installation compare by total cost, pros, and cons in 2026:
| Installation Method | Total Cost in 2026 | Pros | Cons |
|---|---|---|---|
| DIY | $55–$450 | Saves on labor, flexible timing | Risk of mistakes, no labor warranty |
| Pro | $75–$500 | Expertise, warranty, reliable | Higher labor cost, scheduling |
Sometimes a deadbolt can be fixed, while other times replacement is the smarter choice. Knowing when to repair or replace helps you make the most cost-effective decision.
Minor issues, such as a sticky mechanism, loose screws, or slight misalignment, can often be repaired. If your deadbolt is severely damaged, outdated, or you have lost the keys, replacement is the better option. Age, warranty status, and the extent of the problem are all factors in your decision.
Repairing a deadbolt, such as rekeying or minor fixes, costs $20 to $75. Replacing with a new deadbolt, including hardware and labor, ranges from $100 to $300 per lock. If repair costs approach or exceed half the price of a new lock, replacement is recommended.
If you are replacing a deadbolt, consider upgrading to a high-security or smart model. You'll pay more upfront, but the benefits, improved security, added convenience, and potential insurance savings, can make the investment worthwhile.
Deadbolt installation is a practical upgrade that can increase your home's value, safety, and appeal.
Deadbolt installation has a strong return on investment. While it does not drastically increase your home's resale price, it improves security and can lower insurance costs. Compared to other security upgrades, deadbolts are affordable and provide clear value for the money.
Deadbolts give homeowners and buyers greater peace of mind. Smart locks add convenience and efficiency, allowing for keyless entry and remote access. Universal design features make homes accessible for all users, and decorative hardware can enhance your home's appearance.

Purchase deadbolts in bulk for multiple doors to qualify for volume discounts.
Opt for standard models over high-end or smart locks if you're on a budget.
Install during regular business hours to avoid emergency fees.
Get multiple quotes from local pros to compare rates and services.
Consider DIY for simple replacements if you have the tools and skills.
Reuse existing holes and hardware when possible to cut labor time.
