Buyers typically pay for labor plus parts when rekeying a commercial lock, with price influenced by lock type, cylinder count, and whether a master key system exists. The main cost drivers are labor time, lock core compatibility, and any required hardware changes. This article uses clear ranges in USD to help budgets plan.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rekey per lock (standard cylinder) | $60 | $100 | $150 | Labor + core rekey; some locks require drilling for non-standard cores |
| Labor (hourly, commercial) | $60 | $90 | $150 | Typically 0.5–2 hours per cylinder |
| High-security cylinder rekey | $120 | $200 | $350 | Security pins, specialty keys, restricted keyways |
Overview Of Costs
Typical cost range: $120-$600 per building depending on number of locks. The lowest end covers a single standard lock with basic labor, while higher ranges apply to multi-lock rekeys, high-security cylinders, or specialized commercial hardware. The Assumptions: region, number of locks, existing master key system.
Price At A Glance
The price per lock commonly breaks down into a core rekey charge plus labor, with per-lock pricing decreasing on larger jobs. For a small office with 2–4 standard locks, expect around $240–$520. For larger facilities or complex systems, costs can reach $1,000–$1,800 when dozens of locks are included and master-key considerations apply.
Cost Breakdown
Table shows how costs accumulate per project. A typical commercial rekey includes labor, lock cores, and any small consumables. The exact mix varies by lock type and site conditions.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Taxes |
|---|---|---|---|---|---|---|
| $0–$40 | $60–$150 | $0–$20 | $0 | $0–$20 | 12–24 months | 0–8% |
Assumptions: multiple locks on site; standard rekey workflow; no master-key changes.
What Drives Price
Core drivers include lock type, cylinder count, and whether a master key system exists. High-security or restricted-keyways add complexity, while rekeying a single standard lever or mortise cylinder is cheaper. Additional factors include access-controlled hours, on-site safety requirements, and whether locksmiths must disassemble and reassemble door hardware.
Labor, Hours & Rates
Labor costs reflect the time to remove the existing keys from pins, re-pin, and cut new keys. A typical per-lock labor window is 0.5–2 hours, with regional rates affecting the final bill. data-formula=”labor_hours × hourly_rate”> For a 4-lock job, expect 2–6 hours of labor depending on access and lock type.
Regional Price Differences
Prices vary by region due to labor markets and travel time. In the Northeast, expect higher rates; the Midwest tends to be moderate; the South often sees lower base rates. A three-region comparison shows roughly ±10–25% deltas from a national baseline for similar jobs.
Alternative Options & Prices
If rekeying is not suitable, options include replacing cylinders or adopting a new master-key system. Replacement can cost more upfront but may reduce future maintenance. For a single lock, replacement cylinders can run $120–$250 plus labor; for multiple locks, budgeting toward $1,000–$2,500+ is common depending on system complexity.
Regional Price Differences
The cost framework remains similar across regions, but total project price shifts with crew availability and travel time. Urban centers typically add on-site surcharges and permit-related requirements, while suburban sites may benefit from lower hourly rates. Rural sites sometimes incur higher travel fees despite lower hourly wages.
Labor & Installation Time
Time estimates hinge on the number of locks and access constraints. A straightforward rekey of 3 standard locks commonly completes in 1–2 hours; a larger building with 8–12 locks can take 4–8 hours or more. Delays may occur due to keyway approvals or restricted-key systems.
Additional & Hidden Costs
Hidden fees may include overtime premiums, after-hours work, or fees for removing or replacing damaged hardware. Some shops charge a minimum call-out fee even when only one lock is serviced. For complex master-key systems, plan for additional design and testing time to ensure key hierarchies function correctly.
