Homeowners typically spend a modest amount to rekey a home, with costs driven by the number of locks, lock types, and whether a locksmith is used. This guide provides practical price ranges in USD to help budgeting and decision making.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rekey by DIY kits | $15 | $40 | $80 | Low-cost option; requires own tools and basic skills |
| Professional rekey per lock | $60 | $120 | $200 | Standard cylinder rekey; service call included in many quotes |
| Lock hardware (new cylinder) per lock | $20 | $60 | $150 | Includes high-security options |
| Service call fee (if separate) | $0 | $50 | $100 | May be waived with multiple locks |
| Additional security upgrades | $50 | $150 | $500 | Smart locks or graded cylinders add cost |
Assumptions: region, number of locks, lock types, on-site labor hours.
Overview Of Costs
Typical project ranges consider the number of doors and the lock types. For a standard home with 3–4 exterior doors and 1–2 interior door locks, expect a total in the $180-$700 range when hiring a locksmith for basic rekeys, or $60-$120 per lock for the service alone plus $20–$60 per lock in hardware if you source cylinders yourself. For homes with high-security or smart-lock upgrades, totals commonly fall between $400-$1,200, depending on hardware choices and installation complexity.
Per-lock perspective: basic rekeying typically runs $60-$120 per lock. Upgrades to commercial-grade or high-security cylinders push per-lock costs toward the $150-$200 zone, especially when paired with a service call and security reinforcement.

What Drives Price
Lock complexity and number of doors are primary price drivers. A home with 4 exterior doors and 2 interior doors will cost more than a 2-door property. The type of hardware matters: standard pin-tumbler cylinders vs. high-security or smart locks can double or triple lock costs in some cases. Regional labor rates and travel time to reach the property also affect the final bill.
Ways To Save
Compare quotes and consider DIY options for simple cases. If all existing hardware is in good condition, a straightforward rekey of standard cylinders may be cheapest. Purchasing compatible cylinders yourself can reduce per-lock costs, but ensure compatibility and warranty terms. Scheduling during off-peak times or bundling multiple locks into one service call may lower the overall price.
Regional Price Differences
Three-region comparison helps reflect typical U.S. market variance. In the Northeast urban markets, expect higher service calls and labor costs, often pushing per-lock pricing toward the upper end of the range. In the Midwest suburban areas, pricing commonly sits near the average range. Rural regions may see lower labor rates but longer travel fees, potentially offsetting savings. Overall, total project cost can shift by ±20% between these regions depending on travel, availability, and lock type.
Labor & Installation Time
Install time varies with door count and hardware. A 3-door home may take 1–2 hours for a basic rekey, while 4–6 doors with high-security hardware can require 3–5 hours. When planning, a typical locksmith quotes 1–2 hours per 4 doors for standard rekeys, and longer for complicated cylinders or smart-lock integrations.
Additional & Hidden Costs
Hidden costs may include service call minimums and after-hours fees. Some shops charge a minimum service fee even if only one lock is rekeyed. If you request emergency or after-hours service, expect higher hourly rates and possible trip charges. Upgraded hardware or smart-lock integration may entail calibration and app setup fees.
