Deadbolt installation costs average $25 to $500 per lock, with most homeowners spending between $70 and $300 depending on lock type and labor. Standard deadbolts are more affordable, while smart or high-security models cost more. Costs are often quoted per lock installed, with more locks lowering the price per unit.
Adding or upgrading a deadbolt is one of the most effective ways to secure your home. This guide breaks down the factors that impact deadbolt installation cost, helping you plan your project with confidence and avoid surprises.
Cost by Number of Deadbolts
When planning deadbolt installation, the number of locks you need plays a major role in your total cost. Each additional deadbolt adds both hardware and labor expenses, but some professionals offer discounts for installing several locks in a single visit.
Whether you are outfitting a single entry door, updating every door in your home, or securing multiple units, understanding how quantity affects cost will help you budget wisely.
Number of Locks
Installing a single deadbolt is a straightforward project, but it tends to have a higher per-unit cost due to minimum service fees. If you are upgrading all exterior doors or working on a multi-unit property, many pros lower the cost per lock, making whole-home upgrades more affordable per door.
| Number of Deadbolts | Description | Average Cost per Lock | Total Cost |
|---|---|---|---|
| 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 |
Door Size
Standard doors make installation quick and predictable. Oversized, thick, or specialty doors (like metal or custom wood) can increase labor time and sometimes require special hardware. If your door is not pre-drilled or requires reinforcement, you can expect to pay extra for additional labor or materials. Non-standard doors may also need custom-fit deadbolts, which can raise both material and installation costs.
Cost by Deadbolt Type
The type of deadbolt you choose is one of the most important factors affecting your overall installation cost. From simple mechanical locks to advanced smart models, each has its own price point, features, and installation requirements.
Single-cylinder deadbolts are the most common and affordable, while double-cylinder models, smart deadbolts, and commercial-grade locks increase the price due to extra features or added security. Keyless entry options provide convenience but come at a premium.
| Deadbolt Type | Description | Average Cost (Materials Only) |
|---|---|---|
| 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 |
Retrofit vs. New Installation
Replacing an existing deadbolt is less expensive than installing a brand-new one, as the holes and strike plates are already in place. New installations, especially on doors with no previous deadbolt, involve drilling and extra labor, increasing the total cost.
If your door or frame requires modification, it can increase the price. Always check compatibility with your current hardware to avoid surprises.
Brand and Material Quality
Premium brands often charge more for their reputation, warranty, and durability. Deadbolts made from solid brass, stainless steel, or reinforced alloys cost more upfront but last longer and provide better security.
Budget locks may use lighter materials that wear out faster, potentially leading to higher long-term costs. Investing in a reputable brand with a strong warranty can offer peace of mind and reduce the need for future repairs.
Deadbolt Installation Cost by Location
The location of your home and where you install your deadbolt both affect your final price. Labor rates, material costs, and even local demand can all influence what you pay.
Regional Price Differences
Deadbolt installation costs often vary by region. Urban areas and high-cost-of-living cities tend to have higher labor rates, whereas rural locations may offer lower prices but come with additional travel fees. Local demand and the availability of skilled deadbolt installation professionals also play a role.
Installation Location Within Your Home
Installing a deadbolt on a main entry door is the most common and straightforward. Interior doors, garage doors, basement doors, or outbuilding doors may require additional reinforcement or specialty hardware, which can add to the cost.
Hard-to-access locations, multi-story homes, or multi-unit buildings often require more labor, increasing the overall price. If your installer encounters unexpected obstacles, like reinforced frames or old hardware, extra charges may apply.
Deadbolt Installation Cost Factors
There are several factors that impact your total deadbolt installation cost. Let’s examine the most influential ones to help you plan your project and budget effectively.
Labor
Professionals who install deadbolts include locksmiths, handypersons, and security specialists. Locksmiths charge more due to their expertise and licensing.
Labor can be billed per lock, per hour, or as a flat rate. Expect minimum service fees of $50 to $100, and hourly rates ranging from $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
Permits for deadbolt installation are rarely required in residential settings, but some multi-family or commercial buildings may have specific regulations. Permit costs, if needed, are $25 to $100. Always check with your local building department or HOA to confirm requirements before starting work.
Additional Features
Advanced features, including smart lock integration, Wi-Fi or Bluetooth connectivity, keypads, and biometric access, contribute to your project’s cost. These upgrades can range from $30 to $200 per lock, depending on the technology. Reinforced strike plates, anti-drill hardware, and decorative finishes are also available for an added fee.
Installation Add-Ons
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.
Additional Costs to Consider
Beyond installation, there are a few other costs to keep in mind as you plan your deadbolt project.
Warranties
Most deadbolts come with a manufacturer’s warranty covering hardware defects for one to 10 years. Some installers offer labor warranties, covering one year of workmanship. Extended warranty plans are available for an additional fee, but may not be necessary for standard residential installations.
Operating Costs
Smart deadbolts require batteries, which need replacement every six to 12 months. Some models charge connectivity or app subscription fees costing $2 to $10 per month. Traditional deadbolts have no ongoing operating costs.
Maintenance
Routine maintenance includes lubricating the lock, tightening screws, and checking alignment annually. Professional servicing or rekeying averages $20 to $50 per lock. High-quality deadbolts last 5 to 15 years, whereas lower-end models may require replacement sooner.
Taxes
Sales tax on deadbolt hardware and installation services varies by state and locality, adding 5% to 10% to your total bill. Always confirm tax rates in your area when budgeting.
Insurance
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.
DIY Deadbolt Installation vs. Hiring a Pro
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.
| Installation Method | Total Cost | 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 |
Deadbolt Replacement vs. Repair
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.
