Rekeying a house in 2026 runs $80 to $200 total for a standard three-lock home, with most locksmiths charging $15 to $40 per cylinder plus a $40 to $75 service call fee. Here's exactly what drives that number up or down, and how to avoid paying for work you don't need.
- How much does a locksmith cost to rekey a house: expect $80-$200 for 3 locks in 2026, including the service call.
- Per-cylinder rekeying runs $15-$40; adding a deadbolt or smart lock cylinder pushes the total higher.
- Apex Lock N Key and most licensed shops charge a flat $40-$75 dispatch fee separate from the per-lock rate.
- Rekeying beats full lock replacement when your existing hardware is under 10 years old — Buy the rekey, Skip the replacement.
- Same-day mobile service typically adds nothing extra if scheduled during normal business hours.
Why this matters
Rekeying swaps the internal pins in your existing lock cylinder so old keys stop working, without replacing the hardware itself. It's the right move after a move-in, a lost key, a breakup, or a fired employee with a spare copy floating around. Full lock replacement costs more and solves the same problem, so paying for it when a rekey would do the job is money wasted.
The price swings based on lock count, lock brand, and whether you need same-day emergency dispatch versus a scheduled daytime appointment. Knowing the breakdown before you call keeps a locksmith from padding the invoice with vague "parts and labor" line items.
What you'll need
- A count of every exterior lock that needs new pins (front door, back door, garage entry, any deadbolts)
- Proof of residency or ID, since a licensed locksmith should verify you own or lease the property before rekeying
- A decision on whether you want all locks keyed to match one key, which saves labor time
- Cash, card, or the payment method your locksmith accepts — confirm before the visit, not after
- If you're comparing quotes, a licensed and insured provider like Apex Lock N Key can walk you through pricing over the phone before dispatch
The steps to get your house rekeyed at a fair price
1. Count every lock that needs new pins
Walk your exterior doors and count cylinders, not doors — a front door with a knob lock and a separate deadbolt counts as two. This number is the single biggest driver of your final bill, since most locksmiths quote per-cylinder plus one flat service fee. Homes with three standard locks land in the $80-$200 range in 2026; a five-lock property with a garage entry and shed pushes past $250.
Common mistake: forgetting interior locks on a home office or rental unit that also need new pins, which means a second visit and a second service call fee.
2. Call at least two licensed locksmiths for a quote
Ask for the per-cylinder rate and the service call fee separately — a quote that bundles everything into one number hides which part you're overpaying for. A legitimate locksmith gives you both figures on the phone without hedging.
Common mistake: accepting a quote over text or app-based dispatch service without confirming the technician is licensed in Massachusetts, since unlicensed dispatchers often subcontract to whoever's cheapest that day.
3. Verify licensing and insurance before scheduling
Massachusetts requires locksmiths to carry a license, and asking for the license number takes ten seconds on the phone. This step protects you from the bait-and-switch pricing common with national call-center dispatch services that quote low online, then double the price on arrival.
Common mistake: skipping this because the locksmith showed up in a branded van — vans get wrapped for cheap and prove nothing about licensing status.
4. Decide if you want all locks keyed alike
Keying all your locks to a single key costs the same in cylinder parts but can save 10-15 minutes of labor time compared to keying each lock separately, since the locksmith cuts one pin set instead of several. Tell the locksmith this upfront so they bring the right pin kit.
Common mistake: assuming this is automatic — some technicians default to keeping locks separate unless you specify otherwise.
5. Schedule during business hours if it's not an emergency
Mobile locksmiths generally hold their standard rate for daytime, non-emergency appointments and add an after-hours or weekend premium for calls outside that window. If your rekey isn't urgent, a scheduled weekday appointment keeps the invoice at the base per-cylinder rate.
Common mistake: calling at 9pm for a non-urgent rekey and paying an emergency rate for work that could've waited twelve hours.
6. Watch the technician test every key on-site
A rekey isn't finished until the locksmith hands you new keys and tests each one in its lock while you watch. This step takes two minutes and confirms the pins actually seated correctly — a lock that sticks or needs jiggling wasn't rekeyed properly.
Common mistake: paying and letting the technician leave before testing every single lock, not just the first one.
7. Get an itemized receipt
Ask for a receipt breaking out the service call fee from the per-cylinder charge, plus the technician's name and license number. This protects you if a lock fails within days and you need warranty follow-up, and it gives you a paper trail if a landlord or insurer asks for proof of the rekey.
Common mistake: accepting a handwritten total with no breakdown, which makes disputing an overcharge nearly impossible later.
Troubleshooting
The quote jumped once the technician arrived. This usually means the phone quote didn't account for lock brand or a jammed cylinder discovered on-site — ask for the specific reason in writing before agreeing to pay more.
A key works but sticks or requires wiggling. The pins weren't seated fully; a licensed locksmith should fix this on the spot at no extra charge since the job isn't complete until every key turns smoothly.
You were quoted a price 40% below competitors. Rock-bottom online quotes are a common bait-and-switch tactic — confirm the license number and get the service call fee in writing before scheduling.
One lock brand costs more to rekey than the others. High-security brands and certain smart lock cylinders use proprietary pin systems that take longer to service, which explains a higher per-cylinder rate on that lock only.
You lost a key after a recent rekey. Call the same locksmith — they already have your pin configuration on file from the last visit, which can speed up a repeat rekey or duplicate key cut.
Landlord wants proof the rekey happened. The itemized receipt from step 7 covers this; if you didn't get one, call the locksmith back and request a copy.

FAQ
How much does a locksmith cost to rekey a house?
Rekeying a house costs $80 to $200 total in 2026 for a typical three-lock home, based on a $15-$40 per-cylinder rate plus a $40-$75 service call fee. Larger homes with more exterior locks or specialty brands cost more.
Is rekeying cheaper than replacing locks?
Yes, rekeying is almost always cheaper than full lock replacement since it reuses your existing hardware and only swaps the internal pins. Replacement makes sense only when the lock itself is damaged or over 10-15 years old.
How long does it take to rekey a house?
Rekeying takes 15 to 30 minutes per lock for a licensed locksmith, so a standard three-lock home takes under an hour total. Keying all locks alike can shave a few minutes off the total labor time.
Do I need to rekey after moving into a new house?
Yes, rekeying after a move-in is standard practice since you have no way of knowing how many copies of the previous owner's keys exist. Most homeowners schedule this within the first week of moving in.
Can I rekey a smart lock or does it need full replacement?
Most smart locks with a physical key backup can be rekeyed like a standard cylinder, though some proprietary brands charge a higher per-cylinder rate. Confirm with the locksmith over the phone before scheduling.
Does rekeying cost more at night or on weekends?
Emergency, after-hours, or weekend rekeying typically costs more than a scheduled daytime appointment. Booking during regular business hours keeps you at the base per-cylinder rate.
What's the difference between rekeying and changing locks?
Rekeying replaces the internal pins inside your existing lock so old keys stop working, while changing locks replaces the entire hardware. Rekeying costs less and takes less time when the existing lock is still functional.
Should I rekey every lock or just the front door?
Security experts recommend rekeying every exterior lock, not just the front door, since a spare key to any entry point defeats the purpose. Keying all locks alike also means carrying just one key afterward.
One last thing
The detail most homeowners miss: keying every lock on the property to a single key costs the same in parts as keying them separately, but it can shave real labor time off the invoice — ask for it upfront, since not every locksmith offers it unless you specifically request it before the technician arrives.
