Prices to change home locks vary by the type of lock, number of doors, and labor rates. This guide covers cost, price factors, and typical estimates to help homeowners budget for a lock change project. The cost and price ranges below reflect common scenarios across the United States.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Lock Type & Quantity | $35 per standard deadbolt (1) | $75-$150 per lock | $300+ per high-security or smart lock | Depends on hardware quality and number of doors |
| Labor (Installation) | $50-$75 | $100-$180 per lock | $250+ per lock | Includes removal of old hardware |
| Old Hardware Removal & Disposal | $0-$15 | $20-$50 | $100 | Often bundled with labor |
| Rekeying & Master Keying | $15-$40 per lock | $40-$100 per lock | $150+ | Optional if reusing existing hardware |
| Wiring & Electrical Modifications | $0-$50 | $50-$150 | $400 | Relevant for smart locks or powered striking |
| Permits/Inspections | $0-$20 | $50-$150 | $300 | Generally not required for residential lock changes |
| Delivery/Delivery Prep | $0-$15 | $10-$40 | $100 | Lockset delivery or supplier fees |
| Warranty & Support | $0-$10 | $20-$60 | $120 | Limited vs. extended warranties |
| Taxes & Fees | $0-$5 | $5-$20 | $50 | State/local charges may apply |
Assumptions: 1–2 standard exterior doors, 1–2 unlocked interior doors, mid-range residential hardware, standard 1–2 hour install per door, typical suburban pricing.
Overview Of Costs
The total project cost to change home locks typically ranges from $150 to $800 per door, depending on lock type and labor. Lower-cost options include standard cylindrical deadbolts installed on a single exterior door, while higher-cost options cover smart or high-security locks with integrated electronics, plus multiple doors. For a homeowner replacing two exterior doors with mid-range hardware, expect roughly $350-$900 total. Labor time and the chosen lock’s features are the main price drivers.
Cost Breakdown
The following table lists common cost components and typical ranges for a standard home lock change. Prices assume a single exterior door with a mid-range deadbolt and basic rekeying where applicable.
| Columns | Details |
|---|---|
| Materials | Lockset, strike plate, screws; basic deadbolt $40-$120, smart lock $150-$350 per lock |
| Labor | Professional installation; 1–2 hours per door; $100-$180 per lock |
| Equipment | Tools, gauges, drilling templates; usually bundled into labor |
| Permits | Typically not required for residential lock changes |
| Delivery/Disposal | Delivery fees or disposal when removing old hardware |
| Warranty | Standard 1-year warranty on labor; longer on certain products |
| Overhead | Shop/crew overhead embedded in labor rate |
| Contingency | Buffer for hardware incompatibilities or rework |
| Taxes | Sales tax where applicable |
Two key drivers include lock class (cylindrical vs. mortise vs. smart) and the door’s material and thickness. For example, a mortise lock or a smart lock on a solid-wood exterior door adds 40-100% to material costs and increases installation time.

Pricing Variables
Lock changes hinge on several variables. The lock class, door type, and existing hardware influence both material and labor costs. Smart locks offer conveniences but often require wiring, network setup, and compatibility checks that raise both price and installation time. Security goals—standard reliability vs. high-security or keyed-alike setups—also shift the cost curve.
Ways To Save
Smart planning and comparison shopping help reduce costs. Consider combining multiple doors into a single service visit to lock in a bundled rate. If security needs permit, rekeying existing hardware can avoid purchasing new locks, lowering material costs significantly. Request written estimates from at least two licensed pros to compare labor rates and included services.
Regional Price Differences
Prices vary by region due to labor markets and hardware availability. In a typical three-area comparison, suburban Midwest pricing may sit in the mid-range, urban coasts tend to be higher, and rural areas often skew lower. Expect ±20% differences between these regions for both labor and materials, with smart locks and high-security options amplifying regional gaps.
Labor, Hours & Rates
Labor hours depend on door count, hardware complexity, and whether doors are prepped for new hardware. A simple 1-door swap averages 1–2 hours; two doors can require 2–4 hours. Regional labor rates commonly range from $75 to $180 per hour. Planning ahead for crew travel time can help avoid inflated fees.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes. Each uses standard assumptions and notes the total and per-unit costs.
- Basic: One exterior door, standard deadbolt, key rekey, no smart features. Specs: cylindrical deadbolt, 1 door, 1 hour labor. Parts: $40 lock, $100 labor. Total: $140.
- Mid-Range: Two exterior doors, mid-range hardware, one smart-capable unit, rekey on re-used hardware. Specs: 2 locks, 2 hours labor, smart option adds $120. Total: $420-$520 depending on smart model and labor increments.
- Premium: Two exterior doors, high-security or smart locks with installation complexity, additional wiring. Specs: premium locks, 3–4 hours labor, electrical considerations. Total: $700-$1,000+.
Note: Prices shown are per-door or per-project ranges and assume standard installation conditions. Assumptions: region, specs, labor hours.
