Homeowners typically pay a moderate expense to replace door locks, driven by lock type, labor time, and whether rekeying is included. The price range reflects common residential scenarios and standard installation practices.

Pricing improves with clear scope: lock type, number of doors, and whether smart features are included.

Typical Cost Range

For a single exterior door, mechanical lock replacement typically costs $120-$300, while a basic smart lock replacement may be $250-$500. If multiple doors require work, multiply per-door costs accordingly. Prices vary by lock quality, installation complexity, and whether wiring or smart home integration is involved.

Cost Breakdown

What Drives Price

Lock type and features are primary drivers: basic knob locks are cheapest, while deadbolts with reinforced strike plates, anti-snap cylinders, or smart wireless connectivity add cost. The number of doors, metal vs. wooden frames, and door thickness influence labor time and hardware choices.

Other cost factors include assessment time, drill bit wear, potential frame repair, and compatibility with existing wiring for smart locks. For older homes, hidden hardware adjustments may add hours to the job. data-formula=”labor_hours × hourly_rate”>

Ways To Save

Costs can be reduced by choosing standard mechanical locks over smart features, replacing only the lock cylinder when possible, or bundling multiple doors with a single service visit. If rekeying is planned later, request it in the same visit to avoid separate trips. Plan for the minimum required hardware and avoid upgrading components prematurely.

Regional Price Differences

Prices vary by region due to labor rates and hardware availability. In the U.S., typical regional deltas are around ±15% for urban, ±8% for suburban, and ±20% for rural areas, relative to a national baseline. Regional supplier promotions or security-conscious markets can shift costs modestly. Consult local quotes to capture current regional differences.

Labor & Installation Time

Installation time depends on door type and existing hardware. A single standard exterior door usually takes 1–2 hours in typical conditions, while smart lock integrations with home networks may extend to 2–4 hours. Assumptions: one exterior door, standard framing, no major repairs.

Additional & Hidden Costs

Potential extras include extra strike plates for higher security, reinforcement plates for weak doors, and rework if the door won’t latch properly after installation. Hidden fees may appear for rush service or after-hours work. Always request a line-item quote before work begins.
