Home lock changes typically range from a low to average price depending on lock type, number of doors, and whether rekeying or full replacement is chosen. The main cost drivers are lock hardware, labor, and any required permits or services. Cost considerations include door material, lock grade, and whether smart features are involved.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Lockset (deadbolt, handle set, smart lock) | $50 | $150–$350 | $600 | Standard single deadbolt; higher for smart locks with connection features. |
| Rekeying & Labor | $60 | $120–$240 | $350 | Typically 0.5–2 hours per door; increases with complexity. |
| Replace/Install Labor | $100 | $180–$320 | $600 | Per door; includes mounting and alignment. |
| Additional Hardware & Accessories | $10 | $40–$120 | $300 | Strike plates, weatherstripping, screws, retrofit kits. |
| Permits & Taxes | $0 | $10–$50 | $200 | Typically not required for standard interior doors; may apply to exterior upgrades. |
| Delivery/Disposal | $0 | $5–$20 | $50 | Minimal for small hardware; higher with bulky components. |
Assumptions: region, door count, lock type, and whether rekeying or replacement is performed.
Overview Of Costs
data-formula=”labor_hours × hourly_rate”>Prices vary by door count and lock type. Typical projects involve 1–3 exterior doors and 1–2 interior doors.
Typical cost ranges for a simple exterior door with a standard deadbolt and rekey: $120–$320 for a single door, including labor and hardware. Upgrading to a smart lock or higher-grade hardware can raise costs to $300–$600 per door.
Cost Breakdown
Per-door estimation helps compare options quickly. For each door, most homeowners face a base lock price plus labor. The table below shows common component costs and how they combine to form the total.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $50 | $150–$350 | $600 | Deadbolts, handles, or smart lock assemblies. |
| Labor | $60 | $120–$240 | $350 | Includes removal, installation, and alignment. |
| Delivery/Disposal | $0 | $5–$20 | $50 | Small fees for hardware transport or packaging disposal. |
| Permits | $0 | $10–$50 | $200 | Usually not required for standard residential work. |
| Warranty | $0 | $10–$50 | $100 | Limited coverage on parts or labor depending on contractor. |
| Contingency | $0 | $10–$30 | $100 | Buffers for misaligned strike plates or rebates. |
Assumptions: single door, standard frame, no structural work; labor quoted as a flat rate or hourly with a typical crew size.
What Drives Price
Lock type and door characteristics are the main price levers. Exterior doors often need higher-security hardware or weatherproofing, while interior doors require lighter hardware. The choice between rekeying and replacing a lock changes the labor and materials mix significantly.
Factors That Affect Price
Several variables influence final cost beyond the base hardware:
- Lock grade and security features (Grade 1 vs Grade 2; anti-tamper, keyless entry).
- Door material and thickness (wood, steel, fiberglass) and whether the strike plate requires reinforcement.
- Number of doors and whether multi-point locking is involved.
- Smart lock integration (Z-Wave, Bluetooth, Wi‑Fi) and required power sources or hubs.
Regional differences can shift prices by a noticeable margin. Urban markets often show higher labor rates than suburban or rural areas.
Ways To Save
Plan ahead to minimize surprises and optimize costs. Consider rekeying existing hardware when possible, choose mid-range locks, and schedule work during off-peak times to reduce labor rates.
- Compare quotes for rekey vs full replacement per door.
- Match hardware across doors to simplify installation and reduce hardware costs.
- Ask about bundled pricing for multiple doors.
- Check for promotions on smart locks or bundled installation offers.
Regional Price Differences
Prices vary across the United States by region. The following comparison illustrates approximate deltas relative to a national baseline for standard exterior door changes:
- West Coast (urban): +8% to +18% on hardware and labor.
- Midwest (suburban): baseline to +6% depending on city.
- South (rural to suburban): −2% to +5% on average.
Assumptions: single-family homes, typical 1–2 exterior doors, standard deadbolts.
Labor & Installation Time
Labor time for changing a lock depends on door type and security features. A simple rekey and hardware swap per door often takes 0.5–1.5 hours; smart lock installation may take 1.5–2.5 hours per door due to setup and app pairing. Labor hours and rates vary by region and contractor.
Real-World Pricing Examples
Three scenario cards help visualize likely costs for a small home with multiple doors:
- Basic: One exterior door, standard deadbolt, rekey included. Specs: 1 lock, 1 door. Hours: 0.5–1.0. Materials: $50–$120. Total: $120–$260.
- Mid-Range: One exterior door with a mid-tier deadbolt and rekey, plus interior passage door. Specs: 2 locks, 2 door work. Hours: 1.5–2.0. Materials: $150–$320. Total: $300–$700.
- Premium: One exterior door with a smart lock, plus another exterior door upgrade to high-security hardware. Specs: 2 locks, 2 smart components. Hours: 2.0–3.0. Materials: $350–$600. Total: $800–$1,800.
Assumptions: typical homeowner doors, standard installation practices, no structural modifications.
Overall, the cost to change locks on a home in the United States ranges from roughly $120 to $1,800 per door, depending on whether rekeying or full hardware replacement is chosen and the level of security desired. For a common two-door scenario with a mix of rekey and standard hardware, a practical budget range is $400–$1,200 across the project, including per-door labor and materials.
