Rekey Locks Cost: What Drives the Price Per Door

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.

• Rekeying: about $100–$300 per door (HomeGuide).
• Locksmith service call fee: about $50–$150; standard hourly rate about $50–$100 (HomeGuide).
• After-hours or emergency locksmith: about $150–$250 per hour (HomeGuide).
• Overall locksmith visit, blended across rekeys, lockouts and repairs: normal range $107–$242, average $163 (HomeAdvisor).
• Full lock replacement for comparison: about $80–$225 per door, with hardware alone at $35–$150 (HomeGuide).

Rekey or replace

Rekeying changes the pins inside your existing cylinder so old keys no longer work, keeping the hardware you already have. Replacement swaps the whole lock. Rekeying is the usual choice when the hardware is sound and you simply want previous keys invalidated after a purchase, a move-out, a lost key or a contractor handover.

Worth knowing, because it surprises people: HomeGuide's own published figures put replacement per door ($80–$225) at or below rekeying ($100–$300). If your locks are old, worn or low-grade, replacing them can cost the same or less and leaves you with better hardware. Ask the locksmith to price both.

When to rekey immediately

• After closing on a home — you have no way of knowing how many keys exist.
• After a tenant, housemate, ex-partner or employee moves out.
• After a key is lost or stolen, particularly if it was on a ring with anything identifying the address.
• After a break-in, once law enforcement has documented the scene.
• After contractors, cleaners or property managers have held a key during a project.

Getting keyed alike

If your front, back and garage-service doors take different keys, ask for them to be keyed alike during the same visit. Locks generally have to share a compatible keyway for this to work, so the locksmith will check the hardware first, and any lock that cannot be matched can be replaced with one that can.

South Florida specifics

Condominium and association-governed buildings often specify approved hardware and control building entry systems, so unit-door rekeys may be limited to what the association permits.

Salt air and constant humidity corrode exterior cylinders here, and a stiff or seized lock is sometimes a hardware condition problem rather than a keying one.

Seasonal rentals and frequent tenant turnover make rekeying a routine maintenance item across much of South Florida.

Verify the locksmith's identity and business details before work begins, and expect to prove you are the resident — that is normal practice, not an obstacle.

How we handle pricing data

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.
