Replacing a deadbolt typically costs $100-$300 when a locksmith installs a standard lock in an existing door opening; the national midpoint is about $190. The deadbolt’s grade, smart features, door modifications, service-call minimums, and local labor rates can move the total substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Standard deadbolt replacement | $75 | $190 | $350 | Existing hole, standard lock, locksmith labor |
| Deadbolt hardware | $20 | $65 | $180 | Basic single-cylinder to premium high-security model |
| Smart deadbolt installed | $150 | $325 | $600 | Price depends on lock features and door fit |
| New opening or door adjustment | $50 | $150 | $350 | Additional work beyond a like-for-like swap |
Assumptions: U.S. pricing for a standard residential door, normal access, and a non-emergency appointment; local quotes vary.
What does replacing a standard deadbolt usually cost?
A locksmith-installed standard deadbolt generally totals $100-$300, with many straightforward replacements near $150-$225. This assumes a conventional single-cylinder lock, an existing compatible bore, and no damaged door or frame. The average estimate of about $190 includes ordinary hardware and a local service visit, but not a late-night emergency call or extensive carpentry.
Basic replacement hardware can cost $20-$50, while a better-rated or more durable keyed deadbolt often costs $50-$120. High-security cylinders and specialty finishes can push the lock alone to $100-$180 or more. A double-cylinder model, which takes a key on both sides, may cost more and can be restricted by local fire-safety rules.
For a like-for-like swap, the lock and the locksmith’s minimum charge are usually the main expenses. A homeowner who already has the right tools may pay only for the deadbolt, but installation is not a good place to guess about door measurements, strike alignment, or safe operation.
Assumptions: Standard residential deadbolt, existing bore and strike location, ordinary weekday scheduling.
Deadbolt hardware and locksmith labor in the quote
A locksmith estimate may combine hardware, travel, and installation into one amount. Ask whether the quoted price includes the service call, new keys, removal of the old lock, and any adjustment to the strike plate. A low advertised labor rate may not include the minimum visit charge.
| Quote component | Typical price | What it covers | When it increases |
|---|---|---|---|
| Deadbolt hardware | $20-$180 per lock | Basic, quality-grade, or high-security lock | Smart features, restricted keys, premium finish |
| Locksmith visit and labor | $75-$175 total | Travel, removal, fitting, and operation test | High local rates, weekend, or after-hours arrival |
| Keys and cylinder work | $5-$40 | Extra keys or basic keying service | Special key blanks or restricted-key systems |
| Door or frame adjustment | $25-$150 | Strike alignment or minor fitting | Misaligned frame, worn holes, or damaged wood |
| New bore or major repair | $75-$350 | Drilling, patching, or more extensive fitting | New lock location or incompatible door preparation |
Labor may be listed as a flat installation fee rather than an hourly rate. When billed by time, locksmith rates commonly run about $50-$100 per hour, with a minimum charge that can make a short visit cost more than one hour of work.
Compare the all-in total, not just the hardware price or advertised hourly rate. A written quote should identify the lock model or grade, service-call fee, labor, and likely extra charges before work begins.
How door drilling and lock grade change the price
Door preparation can be the difference between a quick replacement and a larger installation job. A standard deadbolt typically fits a 2⅛-inch cross bore and a 1-inch edge bore, but older doors, metal doors, and unusual locksets may not match current dimensions. If the existing holes are compatible and the latch lines up, labor is usually limited to removal, fitting, and testing.
Cutting a new opening or relocating the lock can add about $75-$200 for straightforward drilling, and more if the door needs patching or reinforcement. A new strike plate or minor alignment work may add $25-$100. Steel, fiberglass, and glass-panel doors may need specialized tools or a different installation method; confirm that the chosen lock is suitable for the door before buying it.
Lock grade also affects the hardware budget. A basic residential model may cost $20-$50, while a stronger commercial-style or higher-security deadbolt often runs $60-$180. Grade and security claims are not interchangeable: buyers should check the product specification and confirm that the cylinder, bolt, strike, and frame provide the intended level of protection.
Measure the bore, backset, door thickness, and strike alignment before ordering a replacement. A mismatch can mean return shipping, extra labor, or a second visit. Many residential locks fit common door thicknesses around 1⅜-1¾ inches, but thicker doors may require an extension kit or compatible model.
Assumptions: Typical wood or composite exterior door; specialized metal-door work and major frame repairs can exceed these ranges.
When does a smart deadbolt raise the installed total?
A smart deadbolt replacement commonly costs $150-$600 installed. The lock itself accounts for roughly $100-$350, depending on whether it uses a keypad, phone app, fingerprint reader, Wi-Fi, or a separate bridge. Installation is often $75-$175 when it fits an existing deadbolt opening and the door is in good condition.
Some smart locks replace only the interior thumb-turn and retain the existing exterior key cylinder; others replace the full assembly. That difference affects both compatibility and price. A retrofit model can be less disruptive, while a full keypad lock may require checking the door thickness, backset, and bolt travel. If the existing bore is off-center or the bolt binds, corrections can add $50-$200.
Potential ongoing expenses include batteries, replacement keys, or a paid subscription for optional remote features. Many models do not require a subscription for basic keypad operation, but remote access may depend on a hub or compatible home network equipment. Include these costs only if the feature is needed.
Choose a smart lock by the functions actually used, not by the longest feature list. A keypad-only model may meet a household’s needs without the extra equipment or setup associated with remote access and advanced integrations.
What do locksmiths charge by region and urgency?
Prices vary with local wages, travel distance, business costs, and the availability of locksmiths. A standard weekday replacement in a lower-cost rural or small-town market may land near $75-$200. In many suburbs and mid-priced cities, a typical total is $125-$300. Dense, high-cost metro areas may run $175-$400 for the same basic job, especially when the service call is separate.
As a rough comparison, metro quotes can be 15%-35% above a lower-cost market, while remote rural service may add travel charges rather than a higher hourly rate. These are planning differences, not fixed regional price rules. A local provider’s minimum fee and distance to the property can matter more than the state average.
Evening, weekend, and holiday calls commonly add $50-$150, and urgent or overnight service can add $100-$250 or more. A lockout is not the same as a planned replacement: opening a locked door may carry its own fee, followed by separate charges for the new deadbolt and installation.
Whenever the door is secure, a scheduled weekday appointment usually costs less than emergency dispatch. Before agreeing to urgent work, ask for the total arrival charge and the expected range for parts and installation.
Extra charges for rekeying, keys, and door adjustments
Replacing a deadbolt and rekeying an existing lock are different services. Replacement provides new hardware; rekeying changes the existing cylinder so old keys no longer work. A locksmith may charge about $20-$50 per cylinder to rekey, plus a service-call minimum. Rekeying can be cheaper if the current deadbolt is sound and compatible keys are the only concern.
Additional keys commonly cost $5-$20 each for standard blanks, while restricted or specialty keys may cost $15-$40 or more. Removing a damaged or seized lock can add $25-$100, depending on how much time is required and whether the cylinder can be removed without damaging the door.
Door alignment is another frequent surprise. Seasonal swelling, a sagging door, or a loose frame can prevent the bolt from extending smoothly. A minor strike-plate adjustment may add $25-$75; replacing a damaged strike or reinforcing the frame can cost $50-$200. If the bolt only works when the door is pulled or lifted, mention that when requesting the quote.
Separate necessary security work from optional improvements on the estimate. A replacement deadbolt should extend fully into the strike and operate without force; a new lock will not solve a weak frame or a door that is badly out of alignment.
Can a homeowner replace the lock for less?
For a standard door with a compatible opening, a capable homeowner may install a basic deadbolt for the $20-$120 hardware cost, plus any tools or extra parts. The process generally involves removing the old assembly, fitting the latch and exterior cylinder, securing the interior plate, and checking that the bolt moves freely with the door both open and closed.
DIY work is less attractive when the door is metal, the holes are oversized, the latch is misaligned, or the lock is part of a restricted-key system. A mistake can damage the door or leave the bolt unreliable. Smart locks may also require careful setup and troubleshooting. If a new bore is needed, a proper hole saw, template, and accurate measurements are important.
Hiring a locksmith can be worth the $75-$175 labor and visit charge when the fit is uncertain, the old lock is damaged, or the home needs multiple locks keyed alike. Ask about the incremental price for additional locks during the same visit; bundling several replacements may reduce the per-lock labor charge, although hardware remains a separate cost.
DIY savings are greatest on a simple, same-size replacement—not on a door that needs drilling or repair. Keep the packaging and receipt until the lock has been tested, and verify the key works smoothly before relying on the installation.
Three replacement quotes for common door situations
The examples below show how scope changes a realistic estimate. They are planning figures rather than fixed national prices; market, lock selection, and provider fees affect actual quotes.
| Scenario | Hardware | Labor and other work | Estimated total |
|---|---|---|---|
| Existing wood door, standard lock | $45-$75 | $85-$140, about 1 hour | $130-$215 |
| Keypad deadbolt, existing opening | $150-$250 | $90-$160, about 1-1.5 hours | $240-$410 |
| New bore and frame adjustment | $50-$100 | $175-$325, about 2-3 hours | $225-$425 |
In the first example, a locksmith removes the old deadbolt, installs a comparable model, and tests the bolt and key. The second includes a keypad lock but assumes the existing preparation fits; Wi-Fi accessories, app setup, or door correction could increase the quote. The third assumes a new opening in a workable door and a modest strike adjustment, not extensive frame reconstruction.
For a multi-lock job, the total can rise even when each additional installation is relatively quick. Three standard deadbolts might cost $300-$700 installed, depending on hardware and whether all openings match. Ask whether the service-call charge applies once or separately to each door, and whether the locks can be keyed alike.
Use the scope, lock model, and included labor to compare quotes on equal terms. A useful estimate states whether old hardware removal, keys, door adjustment, and tax are included, and identifies any work that would require approval at an added price.
