Homeowners commonly pay to install a deadbolt to improve security, but costs vary by door type, hardware quality, and labor in their region. This article breaks down the price, with accurate ranges and per-unit details for a typical residential installation. The cost focus helps buyers budget for a new deadbolt, including material options, labor, and common add-ons the price might require.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total installation cost | $150 | $250 | $500 | Includes hardware and basic labor |
| Deadbolt hardware price | $20 | $60 | $200 | Single-cylinder, ANSI grade 2 or 3 |
| Labor cost per hour | $40 | $75 | $125 | Regional variance applies |
| Service call or diagnostic fee | $0 | $50 | $100 | Waived with install in many cases |
| Rekeying or cylinder replacement | $15 | $40 | $80 | Per lock; may be included in package |
| Additional hardware (strike plate, screws) | $5 | $15 | $40 | Solid steel or reinforced variants |
Exact price components for a deadbolt installation
Most buyers pay a bundled price that factors hardware, labor, and potential adjustments. A typical install for a standard exterior door with a common single-cylinder deadbolt ranges from $150 to $350, with higher costs if the door is old, nonstandard, or requires extra work. The exact amount depends on the door material, whether a strike plate needs reinforcement, and if the door frame requires alignment or repair. For more premium hardware or smart deadbolts, the price can rise to $400–$500 or more when installation complexity is added.
| Cost Component | Low | Average | High | What drives it |
|---|---|---|---|---|
| Hardware price | $20 | $60 | $200 | Grade, brand, smart features |
| Labor | $40 | $75 | $125 | Hourly rate, door type, installation time |
| Drilling/adjustments | $0 | $30 | $60 | Old door or misaligned frame increases work |
| Rekeying | $15 | $40 | $80 | Per lock, may be bundled |
| Delivery/Removal | $0 | $10 | $30 | On-site pickup or haul-away |
| Permits/inspection fees | $0 | $0 | $0 | Usually not required for residential interior work |
Which deadbolt style affects the price the most
The type of deadbolt largely drives the overall cost. A basic single-cylinder mechanical bolt is the most affordable, typically $20–$60 for the hardware itself and $150–$250 total installed. A double-cylinder bolt or a high-security model can push the hardware price to $80–$200, with total installed costs around $200–$350. Smart deadbolts, which connect to Wi-Fi or Bluetooth and may include batteries and apps, commonly run $150–$400 for hardware alone and require $250–$500 for installation if electrical work or wiring is needed. Choosing premium materials or smart features raises both parts and labor costs.
Labor realities that influence the final quote
Labor cost is a major factor and varies by region, door type, and the installer’s rate. Typical labor ranges are $40–$125 per hour, with most standard deadbolt installs completing in 1–3 hours. A straightforward job on a new exterior door may sit near $180–$300, while a door that requires frame reinforcement, alignment, or access changes can exceed $350–$500. Expect higher quotes in urban markets or for nonstandard doors.
Region-based price differences you should expect
Prices shift with local demand, contractor rates, and shipping costs for hardware. The Midwest often falls toward the lower end of the spectrum, while coastal cities and tech hubs trend higher. For a basic installation, plan for roughly $150–$300 in many suburban markets, with $300–$500 in dense metro areas or for premium hardware. Regional variance matters when budgeting for multiple doors.
Prices by door type and installation scope
Interior doors with standard thickness and no engraving or router work stay near the lower end: hardware $20–$60, total $150–$250. Exterior doors, reinforced frames, or doors with glass panels may require additional cutting, larger strike plates, or reinforcement plates, adding $50–$150 to the project. If a door is already prepped for a deadbolt, the job may be near the lower end of the range. Scope changes the final price quickly.
How per-unit pricing helps with budgeting
For multi-door scenarios, per-unit pricing makes budgeting simpler. Expect a per-door total of about $150–$350 for basic mechanical models, with per-door hardware costs around $20–$100. For smart deadbolts or high-security units, per-door totals commonly run $250–$500. Bundle pricing is common when multiple doors are installed by the same contractor.
Additional costs to consider beyond the install
Rekeying and strike-plate reinforcement are frequent add-ons. Rekeying a single deadbolt adds roughly $15–$40, while upgrading the strike plate to a reinforced model can add $5–$40. If the frame needs reinforcement or alignment adjustments, expect $20–$100 more. These extras affect total project cost even when hardware remains affordable.
Practical steps to reduce the price without sacrificing security
Start by selecting standard hardware and avoiding smart features if the goal is to minimize costs. Verify door suitability before purchase; a poorly fitting door may require plan changes and extra materials. Schedule installations during off-peak times to reduce labor rates in some markets. Bundling two or more doors with one contractor can yield a modest discount. Careful planning cuts unnecessary expenses.
What a real-world quote often looks like for a single exterior door
A typical quote for a standard single-cylinder deadbolt on an exterior door includes hardware ($40–$80), labor ($80–$150), and possible rekeying ($20–$40). That totals roughly $180–$270 for a basic job, with higher-end hardware or added features pushing the range to $300–$450. Acceptable variance exists due to regional labor rates and door complexity.
When to factor in a repair or replacement decision
If a door or frame is damaged, some contractors offer a combined repair-and-install package. A minor frame repair can add $50–$150, while replacing a door or the entire frame can push the project to $500 or more. For older homes, replacing with a modern, secure deadbolt and compatible strike may justify higher upfront costs for long-term security gains. The cost driver is longevity and reliability as much as immediate install price.
