Lock Replacement Cost: What Drives the Price Per Door
Lock replacement is priced per door plus a service-call component, driven by the hardware chosen, whether the door needs new prep, and when the locksmith is called.
Short answer
Lock replacement cost is driven by how many doors are done in one visit, the grade and type of hardware fitted, whether the door needs new boring or reinforcement, and whether the call is during business hours or after hours. HomeGuide puts full lock replacement at roughly $80 to $225 per door with hardware alone at $35 to $150, against $100 to $300 per door to rekey, so on worn hardware replacement can cost the same or less.

What moves the price
- Number of doors replaced in one visit
- Hardware type and security grade — basic knob set, graded deadbolt, high-security or smart lock
- Whether the door needs new boring, a new strike or reinforcement
- Business hours versus evening, weekend or emergency dispatch
- Service-call or trip fee and travel distance
- Keying several doors alike during the same visit
- Smart lock setup, including app, hub and network configuration
UrgentHomePro does not set, negotiate or influence what a provider charges, and we do not publish our own price figures. Where this page cites a dollar range, it is a third-party national estimate collected from published consumer cost datasets (Angi, HomeAdvisor, HomeGuide, Thumbtack, This Old House, Modernize or Fixr, as cited), not a South Florida-specific figure and not an UrgentHomePro quote. Every number you actually pay comes from the licensed provider quoting your specific job. As the platform accumulates enough legitimate first-party request and transaction data, we will publish anonymized South Florida aggregate cost insights with clear methodology and update dates.
Typical national cost ranges
The ranges above are third-party national estimates pulled from published consumer cost datasets in 2026, and each source is cited at the foot of this page. They are not UrgentHomePro quotes, they are not adjusted for South Florida market conditions, individual provider pricing or current local demand, and they should be read as a sanity check rather than a budget. Only a licensed local provider who has inspected the actual job can give you a real price.
- Lock replacement: about $80–$225 per door, hardware alone about $35–$150 (HomeGuide).
- Rekeying for comparison: about $100–$300 per door (HomeGuide).
- Locksmith service call fee: about $50–$150; standard hourly about $50–$100 (HomeGuide).
- After-hours or emergency dispatch: about $150–$250 per hour (HomeGuide).
- Smart lock installation typically carries a higher hardware cost plus setup time.
Replace or rekey
Rekeying keeps the existing hardware and changes the pins so old keys stop working. Replacement swaps the lock entirely. Rekeying is the usual answer when the hardware is sound and you simply need key control after a move, a lost key or a departing tenant.
Replacement is the answer when the lock is damaged, worn, corroded, low grade, incompatible with rekeying, or when you want to upgrade — a higher security grade, a keyed-alike set, or a smart lock. Because HomeGuide's replacement range sits at or below its rekey range, it is always worth asking for both prices rather than assuming rekeying is the cheaper route.
What to ask for in the quote
- Price per door and what the first-door service call includes.
- The specific hardware brand and grade being fitted, not just 'a deadbolt'.
- Whether the door needs new boring, a reinforced strike or frame repair.
- Whether the doors can be keyed alike and how many keys are supplied.
- After-hours rates if the work cannot wait until business hours.
South Florida specifics
Salt air and constant humidity corrode exterior cylinders and fasteners here, and corrosion is a frequent reason a lock reaches replacement rather than service.
Condominium and HOA rules often govern exterior hardware appearance and building entry systems, so check before upgrading a unit door.
Heat and humidity swell doors and frames, so a bolt that no longer throws may be an alignment problem rather than a failed lock — ask the locksmith to check the strike and frame before replacing hardware.
Expect a locksmith to verify your identity and right to be at the property; that is standard practice.

Frequently asked questions
How much does it cost to replace a door lock?
HomeGuide puts full replacement at roughly $80 to $225 per door with hardware alone at $35 to $150, plus a service call fee of about $50 to $150. These are third-party national estimates, not UrgentHomePro quotes, and after-hours dispatch costs more.
Is it cheaper to rekey or replace a lock?
Not always what people expect. HomeGuide's published ranges put replacement at $80 to $225 per door against $100 to $300 to rekey, so on worn or low-grade hardware replacing can cost the same or less and leaves you with newer locks. Ask for both prices.
How much does smart lock installation cost?
Smart locks carry a higher hardware cost than standard deadbolts, and installation adds setup time for the app, any hub and the home network. Ask whether the quote covers configuration and handover or only the physical fitting, and confirm the lock fits your existing door prep.
Should I replace all my locks after a break-in?
Replace any lock that was forced, drilled or pried, and have the door, frame and strike checked as well — a bent strike or damaged frame leaves a door insecure even with a new lock fitted. Where keys may have been taken, replace or rekey every exterior door including the garage service door.
