2 – 3 (front + back) $70 – $250 $180 – $750
4 – 6 (whole home) $70 – $200 $320 – $1,200
10+ (multi-unit) $70 – $180 $700 – $1,800

Per-lock prices fall as quantity rises because the trip fee and setup are spread across more doors – one lock alone carries the full minimum service fee.1

Cost by lock type (hardware, Angi)

Deadbolt type Materials only
Single-cylinder (key outside, thumb turn in) $25 – $60
Double-cylinder (key both sides) $35 – $80
Keyless mechanical (code entry) $60 – $150
High-security / commercial $80 – $200
Smart deadbolt (Wi-Fi / Bluetooth) $100 – $350

HomeAdvisor’s figures for pro-supplied hardware land in the same place: cylindrical deadbolts $50 to $70, mortise locksets $125 to $175.3 Smart lock features (keypads, app integration, biometrics) add $30 to $200 per lock on top.1

Homewyse prices a full lock-plus-labor job (entry lockset with deadbolt, openings fabricated, strike fitted) at $247 to $511 per door – the high end of the three sources because it bundles hardware retail and full labor.2 Retrofit into an existing deadbolt hole is the cheap path; drilling a fresh door adds labor.1

DIY or hire

Swapping an existing deadbolt is one of the most approachable DIY jobs there is – two screws on the interior plate, a screwdriver, and 15 minutes. Home Depot’s deadbolt section shows current hardware prices from $25 single-cylinder models to $350 smart locks (plain link, not affiliate). Hire a locksmith when the door needs new holes drilled, the frame needs reinforcement, or you want a high-security or smart lock keyed into an existing system. One perk worth claiming: Angi notes upgraded deadbolts can trim 2% to 5% off homeowners insurance.1
