When it comes to protecting your home or business, few security investments deliver more value than a quality deadbolt lock. These sturdy mechanisms serve as the primary barrier between your valuables and potential intruders, making them essential for comprehensive security. But what happens when your existing deadbolt shows signs of wear, damage, or simply needs an upgrade?
The question we hear most often from homeowners is straightforward: “How much does it cost to replace a deadbolt?” While this seems like a simple query, the answer involves several variables that can significantly impact your budget and security outcome.
In this comprehensive guide, we’ll break down deadbolt replacement costs, compare DIY versus professional installation options, explore factors that influence pricing, and provide expert tips for maximizing security while minimizing expenses. Whether you’re replacing a basic lock or upgrading to a smart lock system, this article will help you make an informed decision about your home security investment.
1. How Much Does It Cost to Replace a Deadbolt?
The average cost to replace a deadbolt lock typically ranges from $50 to $250. This wide price range exists because deadbolt replacement involves multiple components—the hardware itself, potential door modifications, and installation labor. Let’s break down these costs to give you a clearer picture:
Deadbolt Replacement Cost Breakdown
| Type of Replacement | Hardware Cost | Labor Cost | Total Cost Range |
| Basic deadbolt replacement | $30-$70 | $20-$100 | $50-$100 |
| High-security deadbolt installation | $80-$150 | $70-$100 | $150-$250 |
| Smart deadbolt lock installation | $150-$300 | $75-$125 | $200-$425 |
| Commercial deadbolt lock replacement | $100-$250 | $100-$150 | $200-$400 |
The costs listed above represent standard industry pricing, but several factors can push these figures higher or lower:
- Lock brand and quality: Budget brands like Defiant cost less than premium options like Schlage or Kwikset
- Door condition: Existing holes versus need for new drilling
- Emergency service: After-hours installation typically costs 1.5-2x standard rates
- Geographic location: Locksmith service fees vary significantly by region
- Additional services: Rekeying or installing multiple locks can affect overall cost
What Does the Average Cost to Install a Deadbolt Include?
When you hire a professional for deadbolt installation service, the quoted price typically includes:
- Assessment of your door and existing lock (if applicable)
- Removal of the old deadbolt lock (for replacements)
- Preparation of the door (drilling or adjusting existing holes if needed)
- Installation of the new deadbolt lock
- Testing to ensure proper operation
- Clean-up and disposal of old hardware
- Basic instructions on operation and maintenance
Some locksmiths may also include a limited warranty on their installation work—typically 30 to 90 days—which can provide additional peace of mind.
2. DIY vs. Professional Deadbolt Replacement: Which One is Better?
One of the most common questions we hear is: “Can I replace a deadbolt myself?” The answer depends on your skills, tools, and the specific installation requirements. Let’s compare both approaches:
DIY Deadbolt Installation
Average DIY cost: $30-$100 (hardware only)
Pros of DIY installation:
- Cost savings: Eliminate labor costs completely
- Convenience: Complete the project on your own schedule
- Learning opportunity: Develop practical home improvement skills
Cons of DIY installation:
- Security risks: Improper installation can compromise protection
- Time-consuming: First-time installations often take 1-2 hours
- Potential door damage: Mistakes can be costly to repair
- Limited warranty: Many manufacturers won’t cover improperly installed products
Best suited for:
- Simple replacements where the door already has correctly sized holes
- Homeowners with basic tools (screwdriver, drill, chisel, tape measure)
- Situations where budget constraints outweigh security concerns
Professional Deadbolt Installation Service
Average professional cost: $100-$250 (parts and labor)
Pros of professional installation:
- Security assurance: Proper installation maximizes protection
- Time efficiency: Typically completed in 30-60 minutes
- Professional assessment: Experts can identify additional security weaknesses
- Warranty protection: Installation often comes with service guarantees
Cons of professional installation:
- Higher cost: Labor typically adds $75-$200 to the project
- Scheduling requirements: Need to arrange appointment times
- Potential upselling: Some technicians may recommend unnecessary services
Best suited for:
- High-security deadbolt installations requiring precise fitting
- Smart lock installations with electronic components
- New door installations requiring drilling and precise measurements
- Homeowners who value security over cost savings
How Long Does It Take to Install a Deadbolt?
A common concern is installation time. For professional locksmiths, standard deadbolt installations typically take:
- Replacement of existing deadbolt: 20-30 minutes
- New installation requiring drilling: 30-60 minutes
- Smart deadbolt lock installation: 45-90 minutes
- Installation with complications (metal doors, unusual sizes): 1-2 hours
DIY installations generally take 2-3 times longer for inexperienced installers, particularly when drilling new holes or working with unfamiliar lock mechanisms.
3. Factors That Affect Deadbolt Replacement Costs
Understanding what influences deadbolt replacement cost helps you budget appropriately. Here are the primary factors that impact pricing:
1. Type of Deadbolt
The type of deadbolt you choose significantly affects both material costs and installation complexity:
Single-cylinder deadbolt ($30-$70)
- Features a keyhole outside and thumb-turn inside
- Most common and affordable option
- Installation is straightforward with standard tools
- Provides good security for most residential applications
Double-cylinder deadbolt ($40-$100)
- Requires a key on both sides of the door
- Enhanced security for doors with windows nearby
- Similar installation complexity to single-cylinder models
- May have building code restrictions in some areas
Keyless entry deadbolt ($100-$250)
- Features electronic keypad instead of traditional keyhole
- Battery-powered with mechanical key backup
- More complex installation with electronic components
- Eliminates concerns about lost keys
Smart deadbolt lock ($150-$300)
- Connects to home automation systems and smartphones
- Features remote locking/unlocking and access monitoring
- Most complex installation with electronic and networking components
- Requires occasional software updates and battery replacement
2. Lock Brand & Security Level
The cost of a deadbolt lock replacement kit varies significantly based on brand and security features:
Budget brands ($30-$70)
- Defiant, AmazonBasics, Gatehouse
- ANSI Grade 3 security (basic residential security)
- Limited warranty (typically 1-5 years)
- Basic finishes and features
Mid-range brands ($80-$150)
- Schlage, Kwikset, Yale
- ANSI Grade 2 security (enhanced residential security)
- Better warranties (typically 5-10 years)
- Multiple finishes and modest anti-pick features
High-security brands ($150-$400)
- Medeco, Mul-T-Lock, high-end Schlage
- ANSI Grade 1 security (highest residential/commercial rating)
- Extensive warranties (often lifetime mechanical)
- Advanced protection against picking, bumping, and drilling
When considering “how much does it cost to replace a Schlage deadbolt” versus a budget brand, remember that premium options typically offer superior pick resistance, stronger materials, and longer warranties—often justifying their higher price.
3. Installation Complexity
The physical installation requirements significantly impact labor costs:
Direct replacement ($20-$50 labor)
- Same brand and model replacement
- No new drilling or door modification required
- Quickest and simplest installation
Standard replacement ($50-$100 labor)
- Different brand or model requiring minor adjustments
- Possible minor hole enlargement or repositioning
- Standard installation time and tools
New installation ($100-$150 labor)
- No existing deadbolt
- Requires drilling new holes and chiseling for the strike plate
- More time-consuming and tool-intensive
Complex installation ($150-$200+ labor)
- Metal doors, unusual door thickness, or non-standard dimensions
- May require special tools and techniques
- Often takes twice as long as standard installations
4. Emergency Locksmith Service
Timing can significantly affect locksmith service fees:
Standard service ($75-$150)
- Regular business hours (typically 8 AM to 5 PM weekdays)
- Scheduled appointment with normal wait times
After-hours service ($150-$250)
- Evenings, weekends, and holidays
- Quick-response appointments outside normal business hours
Emergency service ($200-$300+)
- Immediate response for lockouts or security breaches
- 24/7 availability with priority scheduling
If you’re wondering “how much does a locksmith charge to install a deadbolt?” during an emergency, expect to pay a premium for immediate service, particularly during nights and weekends.

4. How to Save Money on Deadbolt Replacement
Looking to minimize your deadbolt replacement cost without compromising security? Here are practical strategies:
Choose the Right Level of Security
Not every door requires the highest security deadbolt. Consider:
- Front door: Invest in high-security or smart deadbolt ($150-$300)
- Back door: Mid-range security deadbolt ($80-$150)
- Interior doors: Basic deadbolt or privacy lock ($30-$70)
This targeted approach ensures your budget goes toward protecting the most vulnerable entry points.
Consider Rekeying vs. Replacing
If your deadbolt is in good condition but you’ve lost keys or moved into a new home, rekeying might be more economical:
- Average rekeying cost: $20-$50 per lock
- vs. Replacement cost: $50-$250 per lock
The rekeying process changes the internal pins in your lock cylinder without replacing the entire mechanism, invalidating old keys while maintaining your existing hardware.
Bundle Services for Discounts
Many locksmiths offer package pricing:
- Multiple lock discount: 10-15% off when replacing 3+ locks
- Whole-house security packages: Combined savings on deadbolts, doorknobs, and padlocks
- Maintenance plans: Annual inspections with discounted service rates
Ask about package pricing when requesting quotes from local locksmiths.
Timing Your Service Request
Schedule deadbolt installation service strategically:
- Mid-week appointments: Often less expensive than weekend service
- Non-emergency timing: Plan replacements before failures occur
- Seasonal promotions: Many locksmiths offer special pricing during slower periods
Avoiding emergency service calls alone can save 50-100% on labor costs.
DIY When Appropriate
Consider the DIY approach for:
- Direct replacements: Same-brand, same-model swaps
- Secondary entrances: Less critical security points
- Standard door preparations: Pre-drilled doors with standard dimensions
Just remember: the money saved through DIY installation can quickly be lost if security is compromised or door damage occurs.
5. How to Choose the Best Deadbolt for Your Home or Business
Selecting the right deadbolt balances security needs, budget constraints, and feature preferences:
Security Ratings Matter
The American National Standards Institute (ANSI) grades deadbolts on security performance:
ANSI Grade 1
- Highest residential/commercial security rating
- Withstands 10 strikes of 75 pounds force
- 1 million mechanical cycles
- Best protection against forced entry
- Typical cost: $150-$300
ANSI Grade 2
- Enhanced residential security
- Withstands 5 strikes of 75 pounds force
- 800,000 mechanical cycles
- Good protection at moderate price point
- Typical cost: $80-$150
ANSI Grade 3
- Basic residential security
- Withstands 2 strikes of 75 pounds force
- 200,000 mechanical cycles
- Minimum security standard
- Typical cost: $30-$70
For most homeowners, Grade 2 deadbolts offer the best balance of security and affordability, while businesses and high-security residential applications benefit from Grade 1 protection.
Essential Security Features
Beyond basic operation, look for these security-enhancing features:
Anti-pick protection
- Security pins that resist manipulation
- Complex keyways that block picking tools
- Sidebar mechanisms requiring special key cuts
Anti-bump resistance
- Special pins that don’t respond to bumping techniques
- Patented designs with staged pin settings
- Often found in higher-end Schlage and Kwikset models
Drill resistance
- Hardened steel components that resist drilling
- Rotating pins or discs that deflect drill bits
- Metal shields protecting vulnerable mechanisms
Strike plate reinforcement
- Extended strike plates with 3-inch screws
- Distributes force during kick attempts
- Inexpensive upgrade with significant security benefits
Smart Features Worth Considering
The smart deadbolt lock installation cost may be higher, but these conveniences can justify the premium:
Keyless Entry Options
- PIN code access for family members
- Temporary codes for service providers
- Eliminates lost key concerns
Remote Management
- Lock/unlock from anywhere via smartphone
- Receive notifications about lock activity
- Integration with home automation systems
Access Logs
- Track who enters and when
- Verify when children arrive home
- Identify unauthorized access attempts
Auto-Locking
- Programmable timed locking
- Geofencing for automatic operation
- Ensures door is never accidentally left unlocked
When considering the cost of a digital deadbolt lock replacement, factor in these convenience benefits alongside the security value.
Do I Need to Replace My Deadbolt?
How do you know when replacement—rather than repair—is necessary? Look for these warning signs:
Security Concerns
- Lock has been compromised during a break-in attempt
- Keys have been lost or stolen
- You’ve recently moved into a new property
- Current lock has known security vulnerabilities
Mechanical Issues
- Key turns with significant difficulty
- Lock occasionally fails to engage fully
- Internal components make grinding sounds
- Visible rust or corrosion affecting operation
Upgrade Opportunities
- Enhancing security with higher-grade locks
- Adding smart home capabilities
- Matching new door hardware aesthetics
- Standardizing locks for master key systems
If you’re experiencing these issues, deadbolt replacement often provides better long-term value than temporary repairs.
Understanding Different Door Types and Their Requirements
Installation complexity and cost vary significantly depending on door material and construction:
Wood Doors
- Easiest for deadbolt installation
- Standard installation tools work effectively
- Typically requires 1-inch diameter hole for the bolt
- Average installation cost: $50-$100
Metal Doors
- Require special drill bits and techniques
- Often have reinforced cores requiring careful drilling
- May need thread-tapping for secure mounting
- Average installation cost: $100-$150
- If wondering “how much does it cost to replace a deadbolt on a metal door,” expect to pay 30-50% more than standard wood door installation
Fiberglass Doors
- Prone to cracking if drilled incorrectly
- Require precise hole saws and steady pressure
- Often have special reinforcement areas for locks
- Average installation cost: $75-$125
Commercial Doors
- Typically metal construction with specialized hardware
- May require compliance with fire codes and accessibility standards
- Often need higher security Grade 1 deadbolts
- Average commercial deadbolt lock replacement cost: $200-$400
Professional locksmiths have the specialized tools and knowledge to work with all door types, which is often worth the additional labor cost for challenging installations.
Conclusion: Making an Informed Deadbolt Investment
When considering deadbolt replacement, remember that you’re not just buying hardware—you’re investing in your security and peace of mind. The average cost to install a deadbolt by a professional typically ranges from $100-$250, while DIY installation saves on labor but potentially introduces security vulnerabilities if not done correctly.
For most homeowners, the best approach is to:
- Invest in quality hardware that meets your security needs
- Consider professional installation for primary entrances
- Maintain your deadbolts with regular cleaning and lubrication
- Upgrade strategically as technology and security standards evolve
