Door Lock Replacement Cost Guide 2026
Homeowners typically pay for door lock replacement based on the lock type, labor time, and any add-ons like smart features. Main cost drivers include the lock hardware, the door prep needed, and whether new hardware requires wiring or drilling. The following sections provide practical pricing in USD with clear low–average–high ranges and per-unit details.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Lockset (basic deadbolt) | $40 | $80 | $150 | Single-cylinder, standard finish |
| Labor (replacement) | $70 | $130 | $260 | Includes removal of old hardware |
| Smart/Keyless lock | $120 | $250 | $500 | Includes module and app setup |
| Electronic keypad or Bluetooth lock | $140 | $260 | $420 | Requires wiring or low-voltage power |
| Labor time (hours) | $1-$1 | $1-$2 | $3-$4 | Typical 0.5–2 hours |
| Delivery/Removal of old hardware | $0 | $15 | $40 | Depends on location |
| Permits | $0 | $0 | $0 | Typically none for residential door locks |
| Warranty (parts) | $0 | $0 | $50 | Most come with 1-year warranty |
| Overhead & miscellaneous | $5 | $15 | $40 | Shop/dispatch costs |
Assumptions: single exterior door, standard door prep, mid-range labor, installed by a licensed pro where required.
Overview Of Costs
Typical cost range for replacing a door lock spans from roughly $120 to $480, depending on hardware choice and installation complexity. Basic deadbolts with standard finishes fall near the lower end, while smart locks or high-security hardware push toward the high end. For pricing clarity, the per-unit ranges and total project ranges below assume standard doors with no structural repairs.
Per-unit pricing example: a basic deadbolt installed at a single door often costs $60–$120 for labor plus $40–$150 for hardware, totaling $100–$270. For a smart lock with wiring or power, expect $200–$350 in labor and $120–$250 for hardware, totaling $320–$600.
Cost Breakdown
Table shows the main cost categories and ranges to help compare quotes.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $40 | $120 | $260 | Basic deadbolt to premium smart lock |
| Labor | $70 | $130 | $260 | Replacement time varies by lock type |
| Equipment | $0 | $5 | $25 | Drills, bits, wiring tools |
| Permits | $0 | $0 | $0 | Residential typically exempt |
| Delivery/Disposal | $0 | $15 | $40 | Old lock removal and haul away |
| Accessories | $0 | $10 | $30 | Strike plates, screws, keys |
| Warranty | $0 | $0 | $50 | Parts warranty adjust by brand |
| Overhead | $5 | $15 | $40 | Company overhead |
| Taxes | $0 | $0 | $0 | Based on local rate |
Assumptions: standard labor rate; no structural door work; mid-range hardware.
Factors That Affect Price
Key drivers include lock type, door prep, and power needs. A basic deadbolt on a standard exterior door is far cheaper than a multi-point, smart, or electronic lock. If wiring or a low-voltage circuit is required, expect higher labor and materials costs. Tighter door frames or unusual door materials can also raise installation time and cost.
Ways To Save
Smart budgeting tips include choosing standard hardware when possible, scheduling during off-peak seasons, and bundling lock replacements with other door or hardware work. If power runs are needed, consider battery-powered smart locks to reduce wiring complexity. Reusing existing strike plates and ensuring proper alignment can lower labor time.
Regional Price Differences
Prices vary by region due to labor rates and material availability. In the Northeast, expect higher labor costs, while the Midwest may be more price-stable. The South often features mid-range pricing, and rural areas can see lower regional premiums but higher travel fees for professionals. Typical regional deltas may range ±15%–30% from a national average.
Labor & Installation Time
Typical installation time ranges by lock type. A basic deadbolt replacement might take 0.5–1 hour, while a side-door with a smart lock could require 2–4 hours. If wiring runs are necessary, labor could extend to 3–4 hours. A simple job keeps the total below $200, while more complex installs can near $500 or more depending on hardware and access.
Real-World Pricing Examples
Three scenario cards illustrate common outcomes.
Assumptions: single exterior door, standard frame, mid-range hardware, licensed labor where required.
Basic — Basic deadbolt, standard finish, standard install: Lock $40–$60; Labor $70–$110; Total $110–$180.
Mid-Range — Deadbolt plus upgraded interior hardware or electronic keypad, partial rewiring: Lock $80–$160; Labor $120–$180; Total $200–$360.
Premium — Smart lock with app setup, longer wiring run, professional calibration: Lock $150–$260; Labor $180–$300; Total $330–$600.
Cost By Region
Three-region snapshot shows relative price movement. Urban areas tend to be 10%–25% higher than rural due to higher labor costs. Suburban markets often fall between, with typical deltas of ±5%–15% versus national averages. For a basic deadbolt, this could translate to $110–$210 in urban areas vs. $100–$190 in rural settings, all else equal.
What Drives Price
Understanding drivers helps align quotes with needs. Hardware quality (brand, security rating), lock type (deadbolt, handle set, smart lock), installation difficulty (door material, alignment), and power requirements for electronic options all steer final pricing. For example, high-security mortise locks and multi-point systems substantially raise both material and labor costs compared with standard cylindrical deadbolts.
Real-World Pricing Snapshot
Three quick quotes for common doors:
- Plain exterior door with standard deadbolt: Total $120–$240; $/hour$ labor around $90–$140; materials $40–$150.
- Exterior door with keypad entry: Total $260–$480; materials $120–$260; labor $140–$220.
- Smart lock replacement with wiring and app setup: Total $350–$700; materials $180–$350; labor $170–$350.
