What Professional Rekeying Actually Costs in 2026
The cost to rekey home locks professionally depends on how many cylinders you have, the hardware itself, and whether the job is scheduled or an emergency. Most homeowners pay a service call fee plus a per-cylinder charge, and that total is what actually lands on the invoice. At Anytime Unlock and George’s Key Shop, we quote the full job before we roll a truck.
Rekeying is the process of removing the existing key pins from a lock cylinder and installing new ones so the old keys no longer work while the lock hardware stays in place. It is not the same as replacing the lock.
Average Cost Per Cylinder
Pricing is quoted per cylinder, not per door. A single door with a knob and a separate deadbolt is two cylinders, which is where most homeowners underestimate the bill.
- Service call fee: a flat trip charge that covers the visit itself
- Per-cylinder rekey: the labor and new pins for each lock
- After-hours surcharge: added for nights, weekends, and holidays
- Hardware replacement: only if the cylinder is damaged or non-standard
Because rates vary by market, hardware, and time of day, we don’t publish a flat number. Call or request a quote and you’ll get an exact figure before anyone is dispatched.
Rekeying vs Replacing Locks: Which Makes Sense for You
Rekeying wins when the hardware is solid and you only need the old keys to stop working. Replacing locks is the better call when the hardware is worn, cheap, or you want a genuine security upgrade.
| Situation | Rekey | Replace |
|---|---|---|
| Moved into a new home | Yes | Only if hardware is worn |
| Lost a key or a key was stolen | Yes | If the lock is damaged |
| Upgrading to a higher security grade | No | Yes |
| Adding smart lock features | No | Yes |
| One key for every door | Yes | Yes, if mismatched |
Replacing locks costs more because you are buying hardware on top of labor. Rekeying reuses the lock body, the deadbolt, and the door hardware you already own, which is why it is almost always the cheaper path when the lock itself is in good shape.
How Long Does It Take to Rekey a House?
A typical home takes about 15 to 30 minutes per cylinder once the locksmith is on site, so a standard house with three or four entry points usually runs under two hours. The clock starts when the technician arrives, not when you call.
What stretches the timeline:
- Sticky or seized cylinders that need to be removed and cleaned
- Non-standard hardware that requires a trip back to the van for the right pins
- Doors with multiple locks that all need to match one new key
- After-hours calls where scheduling, not labor, adds the delay
If you are moving in and want every exterior door on one key, say so when you book. It changes how the technician sequences the work and often saves a second visit.
What Is a Locksmith Service Call Fee and Why It Matters
A locksmith service call fee is the flat charge for the technician to travel to your location, separate from the labor for the work itself. It is the single most misunderstood line on a locksmith invoice.
Here is why it matters. Two companies can quote the same per-cylinder rate and still land at very different totals, because one folds travel into the labor and the other bills it separately. When you compare quotes, compare the all-in number, not the headline rate.
A common mistake is choosing a locksmith purely on the lowest advertised per-lock price. That figure often excludes the service call, the after-hours surcharge, and any hardware. Ask three questions before booking:
- What is the total, including the service call?
- Is there an after-hours or emergency surcharge?
- Does the quote include new keys and pins?
A reputable shop answers all three without hesitation. The Federal Trade Commission's consumer guidance on service pricing is clear that businesses should disclose fees before you commit, which is a fair standard to hold any locksmith to.
Factors That Change the Cost to Rekey Home Locks
No two homes price the same, and the variables are predictable once you know them. The biggest drivers are cylinder count, hardware type, security grade, timing, and, the one most guides skip, where you live.
- Number of cylinders: every lock on every exterior door counts. A front door with a knob and a separate deadbolt is two cylinders, not one.
- Lock type: standard pin-tumbler cylinders are straightforward; high-security and restricted-keyway locks (for example, those using patented keyways) require proprietary pins and blanks that cost more and may need to be ordered.
- Security grade: higher-grade hardware takes longer to service correctly and may require specific pin kits.
- Timing: nights, weekends, and holidays carry a surcharge that can double the labor portion.
- Access: a second-story door, a gate lock, or a lock behind heavy furniture adds time.
- Condition: corroded, painted-over, or seized cylinders take more labor and may need removal and cleaning before rekeying.
- Region: labor rates, licensing requirements, and demand vary widely by market, which is why the same job can price differently in two cities.
Lock Type, Security Grade, and Hardware Compatibility
Lock cylinder is the rotating plug inside the lock that the key turns, and it is the part a rekey actually changes. The cylinder housing stays; only the internal pins change.
Security grade matters here.
Regional Price Variance and the Phone-Quote Checklist
- What is the total, including the service call fee, for my address?
- How many cylinders do you count on my home, and what is the per-cylinder rate?
- Does the quote include new keys and pins, or are those extra?
- Is there an after-hours, weekend, or holiday surcharge, and how much?
- Do you carry pins and blanks for my lock brand, or will that require a return trip?
- Will you call me before doing any work beyond the quoted scope?
- Can you send the quote in writing or by text before dispatch?
The Federal Trade Commission's consumer guidance on service pricing is clear that businesses should disclose fees before you commit, which is a fair standard to hold any locksmith to.
Smart Locks and Master Key Systems: What Most Guides Skip
For commercial properties, a proper security assessment should also cover entry door security, key control, and how many people hold a key. That is a different conversation from a residential rekey, and it is worth having before you hand out copies.
How to Avoid Getting Overcharged for a Rekey
The fix is simple: get the all-in number before anyone touches your door. Overcharging in this trade almost always comes from vague phone quotes, not from dishonest labor rates.
Use this checklist before you book:
- Ask for the total including the service call fee
- Confirm the per-cylinder rate and how many cylinders you have
- Ask whether the quote includes new keys and pins
- Confirm any after-hours or emergency surcharge in advance
- Ask if the technician carries pins for your lock brand
- Get the quote in writing or by text before dispatch
- Confirm the company will call if the scope changes mid-job
Frequently Asked Questions
Is it cheaper to rekey locks or replace them?
Rekeying almost always costs less than replacing locks because you keep the existing hardware and only swap the internal pins. Replacement means buying new locksets, deadbolts, and door hardware plus paying for professional installation on top of it. If your current locks are in good shape and meet modern security grade standards, rekeying is the practical choice. Replace instead when the hardware is damaged, corroded, or you want to upgrade to a smart lock.
What factors influence the total cost to rekey home locks professionally?
The biggest drivers are the number of lock cylinders, the type of lock hardware, and whether the locks are standard or high-security. A locksmith service call fee, after-hours surcharges, and regional labor rates also affect the total. Homes with five or more entry points cost more than a single-door rekey. If your locks use uncommon key blanks or you want a master key system set up, expect that to add to the job.
How long does it take to rekey a house?
A single lock cylinder takes a locksmith about 10 to 15 minutes. A typical house with three to five entry points is usually done in 30 to 60 minutes on site. Add travel time and setup, and most homeowners are looking at roughly an hour to 90 minutes from arrival to finish. Complex jobs, like rekeying a home with a master key system or older hardware, can run longer.
Does rekeying work with smart locks?
Most smart locks use a standard keyway cylinder, so rekeying is possible on the mechanical backup portion. However, some models have sealed or proprietary cylinders that cannot be re-pinned. If you have a smart lock, tell the locksmith the brand and model before the appointment. If rekeying is not an option, the alternative is replacing the cylinder or upgrading the lock entirely.
