Buyers typically pay for rekeying a commercial lock to restore key control after tenant turnover, staff changes, or security upgrades. The main cost drivers are the number of locks, lock type, and labor time. This article breaks down the cost of rekeying a commercial system in clear, practical ranges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Per Lock Rekeying | $40 | $120 | $250 | Standard cores and keys; includes new keys |
| Labor for a Building (3–6 locks) | $150 | $500 | $1,200 | Includes technician travel; assumes 1–2 hours per lock |
| Master Key System / High-Security Cylinders | $200 | $600 | $1,000 | Specialized cores and keying schemes |
| Trip and Minimum Service Fee | $0 | $60 | $150 | Separate charge if no immediate work |
Overview Of Costs
Rekeying commercial locks involves per-lock costs plus labor, with high-security or master-key systems pushing totals higher. Typical projects range from a few hundred dollars for 1–2 standard locks to over a thousand for multiple high-security or master-key configurations. Assumptions: region, lock count, and labor hours vary by building size and door types.
Cost Breakdown
The breakdown below uses both totals and per-unit pricing to reflect common scenarios. For a small office with 3 standard locks, the total may sit around $360–$900 (3 × $40–$120) plus minimal labor. A mid-size building with 6 standard locks often costs $720–$1,800, including labor. A larger installation with 10 locks, some high-security cylinders, and a master-key plan can reach $2,000–$4,000 or more, depending on components and labor time.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Taxes |
|---|---|---|---|---|---|---|
| $0–$60 per lock for standard cores | $40–$120 per lock | $0–$25 per lock (tools) | $0–$0 per project | $0–$20 per visit | 6–24 months depending on vendor | 0–9% depending on state |
What Drives Price
Key price drivers include lock type, number of locks, and required keying scheme. The most common variables are the lock species (standard vs. high-security), the need for a master-key system, and whether multiple doors use the same core family. For example, high-security cylinders or smart-lock compatible cores elevate both parts and labor costs. Additionally, larger sites incur travel and setup time that scale with site count and accessibility.
Factors That Affect Price
Regional labor rates, door hardware availability, and project timing affect final pricing. Labor usually accounts for the majority of cost, with per-lock pricing decreasing slightly as lock counts rise due to efficiency. SEER-quality or security grade choices, lock brands, and keying complexity (single- vs. multiple-level master keys) add layers of cost. For building managers, expect higher quotes for glass doors, steel frames, or restricted-access core types.
Ways To Save
Strategies to reduce out-of-pocket costs include consolidating locks on a single key system and scheduling during off-peak times. Request quotes that group multiple doors to minimize onsite visits, and consider standard cores instead of premium high-security options where feasible. Some vendors offer a flat-rate per-door package for common configurations, which can improve budgeting accuracy. Ensure you factor in the required number of spare keys and any rekeying of auxiliary access points.
Regional Price Differences
Prices vary by region due to labor markets and supply chains. In the Northeast urban centers, expect higher labor surcharges; the Midwest may offer moderate rates; the South and rural areas often show lower prices. Typical regional deltas range from ±10% to ±25% for labor and core costs, depending on door type and service availability.
Labor & Installation Time
Time on site scales with door count and complexity. A basic 2–3 door rekey might take 1–2 hours, whereas a mid-size building with 8–12 doors or a master-key system can require 4–8 hours. If technicians must drill or replace cores due to compatibility issues, time and cost rise accordingly. Use the following rough guidance: 1–2 hours per lock for standard rekeys, 2–4 hours per lock for high-security or master-key implementations.
Real-World Pricing Examples
Assumptions: region, building size, lock types, and labor hours.
Basic Scenario: 2 standard office doors, non-master keys, standard cylinders. Locks: 2; Keys changed; Labor: ~2 hours; Total: $80–$300; Per-door: $40–$150.
Mid-Range Scenario: 6 doors with mixed standard cores and a single master-key plan. Locks: 6; Keys changed; Labor: ~5–6 hours; Total: $600–$1,800; Per-door: $100–$300.
Premium Scenario: 12 doors, high-security cylinders with master-key system and controlled access. Locks: 12; Keys changed; Labor: ~12–16 hours; Total: $2,000–$4,000; Per-door: $167–$333.
