Service and property

Pick the service, count the locks or cylinders, and note the property type. Time of day sets the service-call surcharge.

Service call and add-ons

Prices are editable defaults per lock and per add-on. Add a trip fee, key replacement, or smart lock install as needed.

What the calculator estimates

It turns your service type, lock count, property type, time of day, service call, and add-ons into a planning cost. Rekey is the cheapest per lock, lock changes cost more, and after-hours or emergency service raises the price sharply.

How locksmith service is priced

Most locksmiths charge a base fee per lock or cylinder plus a service-call trip fee. Property type, lock grade, time of day, urgency, extra keys, new hardware, and smart lock install add to the base. Region and provider set the per-lock rate.

Planning note

Locksmith pricing changes with lock type, lock grade, property access, time of day, and local labor. Always confirm the service-call fee, per-lock rate, and after-hours surcharge before booking, especially for emergencies.

Formula used

  1. Lock or cylinder count is entered for the service.
  2. Property factor scales the rate: residential is baseline, commercial adds cost, automotive varies.
  3. Lock grade factor scales the rate: standard is baseline, high security and smart cost more.
  4. Labor cost = locks x base price x property factor x lock grade factor.
  5. Service call = trip fee x time-of-day surcharge x urgency multiplier.
  6. Extra keys = extra key count x price per extra key.
  7. New hardware adds a flat fee when a new lockset is selected.
  8. Smart lock install adds a flat fee when selected.
  9. Total cost = labor + service call + extra keys + hardware + smart install.
How much does a locksmith cost?

A standard residential rekey averages about 80 to 150 dollars total, including the service call. A house lockout runs about 100 to 200 dollars during business hours. After-hours, night, and holiday service adds a surcharge that can double the cost. This calculator lets you set the per-lock rate and surcharges for any quote.

How much does a locksmith cost per lock?

Rekeying a single standard residential lock runs about 20 to 50 dollars per lock, plus the service call. Lock changes run about 50 to 100 dollars per lock, and high-security or smart locks cost more. Commercial locks run higher than residential. Set the base price per lock in this calculator to match your local market.

How much does a locksmith cost after hours?

After-hours locksmith service adds a surcharge of 50 to 150 dollars on top of the base service call. Night and emergency calls cost more than evening calls, and weekends and holidays add the highest surcharge. Always ask for the total including the after-hours fee before the technician is dispatched.

How much does it cost to rekey a house?

Rekeying a typical house with 3 to 6 locks runs about 80 to 200 dollars total, including the service call. Each extra lock adds about 20 to 30 dollars. Rekey is cheaper than replacing the locks and is the standard option when you move in or lose a key. Use the rekey service type and lock count in this calculator.

Does smart lock installation add cost?

Yes. Installing a smart lock adds a flat labor fee plus the cost of the lock itself, and electronic or keypad models cost more to install than a standard deadbolt. Use the smart lock install option to add that line.

Is this a locksmith quote?

No. It is a planning estimate. Lock type, lock grade, property access, time of day, urgency, hardware brand, taxes, and labor vary by provider, region, and site conditions.
