Rekeying locks is a common cost-driven option to restore security after losing a key or changing access. The price primarily depends on lock type, cylinder complexity, and whether new hardware is needed. This article details typical cost ranges, line-item components, and ways to trim the bill for U.S. buyers seeking a reliable estimate for rekeying locks.
Note: The figures below reflect typical residential rekey work and assume standard door hardware, basic pin-tandem cylinders, and normal access. Regional labor rates and part quality can shift totals.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Per-Lock Rekey (standard cylinder) | $40 | $70 | $120 | Labor + pins + setup |
| Board/Manufacturer Keyway Change | $20 | $50 | $90 | If a different keyway is required |
| Hardware Replacement (optional) | $15 | $40 | $120 | Locks or cylinders replaced |
| Service Call Fee | $0 | $40 | $75 | Applied if no labor on-site |
| Multiple Locks (3–4 doors) | $120 | $210 | $420 | Bulk pricing often offered |
Residential Lock Rekey Costs by Type and Quantity
Residential rekey pricing varies by cylinder type and the number of locks. For a single standard deadbolt, expect about $40-$100 per lock, with Assumptions: standard residential hardware, no high-security features, urban market. For door knob cylinders, the range is typically $40-$90 per unit. When rekeying 2–3 doors, the combined cost often lands in the $100-$260 range, including labor and pins.
Specifics: High-security or restricted-keyway cylinders may push per-lock costs to the $120-$150 zone, while including new hardware can raise total by $50-$120 per lock. The per-unit price can be lower when a single technician services multiple doors in one trip.
Major Price Components in a Rekey Job
Pricing breaks down into distinct parts that buyers can compare side-by-side. A typical quote includes materials, labor, and service charges, with optional additions for hardware or specialty cylinders. Table shows common components and ranges for a standard rekey.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $5-$25 | $15-$40 | $40-$85 | Pins, springs, cylinders if replaced |
| Labor | $25-$40 | $45-$70 | $90-$120 | Hourly or fixed per-lock |
| Permits | $0 | $0-$20 | $50 | Usually not required for standard rekeys |
| Delivery/Removal | $0 | $0-$10 | $20 | Material handling if on-site components arrive |
| Warranty | $0 | $0-$10 | $25 | Limited warranty on workmanship |
Key Variables That Change the Final Rekey Quote
The final price fluctuates with several concrete factors. For example, a high-security cylinder with a restricted keyway can add roughly $40-$60 per lock to the bill. Length of run time, such as a hallway with multiple entrances, can push labor hours from 1–1.5 hours per lock to 2–3 hours for complex assemblies. Assumptions: standard access, mid-tier labor rates, typical home geometry.
Other drivers: region-specific labor rates (urban areas higher), and whether locksmiths supply and cut new keys on-site or ship cut keys to duplicates shop. For multi-door homes in dense markets, a bulk-visit discount frequently appears, lowering per-lock cost.
Regional Price Variations for Rekey Services
Prices differ across U.S. regions due to labor, demand, and travel time. In the Midwest, a typical rekey might land near $60-$90 per lock; in the Northeast, $70-$110 per lock; on the West Coast, rates commonly reach $75-$120 per lock. Rural markets may fall toward $40-$70 per lock, depending on provider availability. Assumptions: markets with standard travel time and normal labor supply.
When planning quotes, ask for a price range that reflects travel time and minimum service fees to avoid surprise charges.
Labor Time and Crew Size for Rekey Work
Job duration depends on door count and cylinder type. A single standard deadbolt rekey typically takes 20–45 minutes per door, while knob-style hardware can be faster or slower depending on access. A two-door job may require 1–2 hours total, and a four-door job could run 2–4 hours. If multiple technicians are needed, expect a per-hour premium. Assumptions: one technician handles all locks unless specified.
Scheduling tip: request all work in a single visit if possible to minimize dispatch fees and duplicate travel time.
Per-Unit Rekey Pricing: Per Lock and Per Cylinder
When sellers quote per unit, rekey pricing often appears as per-lock or per-cylinder. A standard deadbolt rekey is commonly $40-$100, while a knob-lock rekey often sits in the $40-$90 range. If a single job covers 3 doors, the per-unit average may decline to $60-$80 per lock due to bundled labor. Assumption: uniform access and no added security features.
Optional hardware upgrade: replacing an entire cylinder with a high-security model can add $50-$150 per unit but may reduce risk with key control improvements.
