Quick Summary
Residential lock rekeying cost is usually priced per cylinder plus a service or trip fee, with most typical houses landing around $210 to $820 total before tax and extra keys. The exact lock rekeying cost depends on how many cylinders you have, their type, and whether the visit is scheduled or after hours.
- Rekeying changes the internal pins of an existing cylinder, so it is usually cheaper than replacing the lock.
- A typical house with 4 to 6 cylinders commonly costs about $210 to $820 total, per the article's planning figures.
- Ask for a written quote listing per-cylinder charges, trip fees, extra keys and tax before work begins.
- A quote without a trip fee, key count or tax is not a complete total and can make options look cheaper than they are.
- DIY rekeying kits cost less but cannot handle high-security cylinders and risk mistakes that end up costing more.

What Is Rekeying a Lock and How It Differs From Changing It
Lock rekeying is the process of changing the internal pins inside an existing lock cylinder so that a different key operates it.
Changing a lock is a bigger job. It means removing the entire lock assembly and installing a new one, which may have a different brand, grade or finish.
This distinction matters for cost. Rekeying is usually the lower-cost option when the existing lock is in good condition.

Average Residential Lock Rekeying Cost in the United States
Most residential rekeying quotes in the United States fall into a predictable structure: a per-cylinder labor charge, a service-call or trip fee, and the cost of any extra keys. Rekeying pricing depends on the number of cylinders, the lock type, whether the visit is scheduled or after hours, and any extra keys needed.
Ask any locksmith for a written quote before work begins. A reliable quote should list the rekeying charge per cylinder, any service call or trip fee, whether extra keys are included, and whether tax is added.
Cost per lock or door
Most residential quotes are built per cylinder. A front door deadbolt, a back door and a garage entry each require their own rekey. A common pattern is a base per-cylinder rate for standard pin-tumbler locks, with add-ons for high-security cylinders (restricted keyways and tighter pin tolerances), specialty or antique hardware, and cylinders that need to be removed and bench-rekeyed because of door alignment or trim interference. Knob-and-deadbolt pairs on the same door are usually priced as two cylinders, not one.
Typical total cost for a house
Total cost scales with cylinder count plus one trip fee, not with square footage. Using the midpoints of common national ranges, here is how the math tends to break down for three common scopes:
- A few locks (2-3 cylinders): roughly $80 to $360 in per-cylinder labor, plus a $50 to $100 service fee, commonly about $130 to $460 total before tax and extra keys.
- A typical house (4-6 cylinders, including entry doors and a garage entry): roughly $160 to $720 in per-cylinder labor, plus the service fee, commonly about $210 to $820 total.
- A larger home (8-12 cylinders, including patio and secondary doors): roughly $320 to $1,440 in per-cylinder labor, plus the service fee, commonly about $370 to $1,540 total.
These are planning figures built from published national ranges, not a quote for your home. The variables that move the total most are cylinder count, cylinder type, whether keys are keyed alike, and whether the visit is scheduled during business hours. Confirm the total in writing before the technician starts, so the final bill matches the estimate.

How Much Does It Cost to Change Locks on Two Doors?
Changing two locks generally costs more than rekeying the same two doors, because each replacement requires new hardware and installation. Hardware quality is the biggest variable. Abra Key Dabra can provide a written quote for your specific doors.
If you are replacing locks for security reasons, compare the total of two new locks against the total of rekeying. In many cases, rekeying is the better value unless the existing locks are worn, damaged or lack features you want.
Rekeying vs Changing Locks Cost: Which Is Cheaper and When
Rekeying is almost always the cheaper option when the lock works well and you only need to change access. Replacement is more appropriate when the hardware fails or does not meet your security goals.
When homeowners should rekey locks
Rekeying makes sense after a move into a new home, when keys go missing, after a roommate or contractor leaves, or when you want to stop a former tenant or employee from entering. It is also a good choice when your locks still turn smoothly and show no signs of damage.
When replacing a lock makes more sense
Replace the lock when the cylinder is damaged, the bolt does not seat properly, or the hardware is old enough to be a security weakness. Replacement is also worth considering when you want a higher security grade, keyless entry, or a different finish that the existing lock cannot provide.
Factors That Affect Locksmith Pricing and What a Quote Includes
Several factors shape the final bill. Knowing them helps you read quotes accurately and compare like-for-like instead of comparing a phone estimate to a written total.
Minimum service and trip fees
Many locksmiths charge a minimum service fee or a trip charge to cover travel and dispatch. This fee may be separate from the per-lock rate. Ask whether the fee applies to your job and whether it covers the first lock or is charged once per visit.
Lock compatibility and matching one key
Locks can be keyed alike so that one key opens several doors. This is convenient but depends on hardware compatibility, not just the locksmith's willingness. To key cylinders alike, they generally need to share the same keyway family and use pin stacks that can be built to a common key cut. Mixing brands, mixing knob and deadbolt styles, or combining a standard cylinder with a restricted high-security cylinder often makes keyed-alike work impossible without replacing at least one cylinder. Some brands also restrict key blanks and pin kits to authorized dealers, which limits what a general locksmith can match.
What a quoted price should include
A quote you can compare should state, in writing: the per-cylinder rekey charge, the service-call or trip fee, the number of new keys included and the cost of extras, whether hardware adjustments (strikes, latches, cylinder swaps) are included, whether tax is added, and whether the price is a flat total or an estimate that can change on site. Ask whether the quote is per lock or for the whole job, a per-lock quote plus a trip fee can look cheaper than a flat total until you multiply it out.
How to verify a quote and avoid surprise charges
Before booking, confirm the total price in writing, the service address, the company's license or registration where your state requires one, and whether the technician will confirm the price again before starting.
Watch out: a quote that omits the trip fee, key count, or tax is not a total, and comparing it to a written all-in estimate will make the wrong option look cheaper.

Rekeying Kit Option: DIY Cost and Limitations
Rekeying kits are sold online and in hardware stores. The kit is generally less expensive than a professional visit, but it has real limits.
DIY rekeying requires patience and accuracy. Incorrect pin stacks can leave a lock stuck or unable to open.
If you are comfortable with small mechanical tasks and your locks are standard, a kit may save money.

Frequently Asked Questions
How much should it cost to get a lock rekeyed?
Rekeying a single residential lock typically costs less than replacing it, and many locksmiths quote a per-cylinder price plus a service or trip fee. Exact pricing depends on the lock type, how many cylinders you need rekeyed, whether the service is after hours, and your location. Ask for an itemized quote in writing before the technician arrives so you can confirm the service call fee, per-lock rate, and any parts charges. Abra Key Dabra can provide a quote for your specific home.
Is it cheaper to replace locks or rekey them?
Rekeying is usually cheaper than replacing locks because the existing hardware stays in place and only the internal pin tumblers change. Replacement adds the cost of new hardware and installation. Rekeying makes sense when the locks are in good condition and you only need the old keys to stop working. Replacement is the better choice when locks are worn, damaged, or you want a higher security grade.
What is included in a residential lock rekeying service?
A rekeying service generally includes removing the lock cylinder, replacing the internal pins with a new combination, and testing the lock with new keys. Many providers also include the cost of the new keys in the quote, though some charge separately. Confirm whether the quote covers a trip fee, the number of keys, and any cylinders that cannot be rekeyed, such as certain older or specialty locks.
Does rekeying a lock work with the existing key?
No. Rekeying changes the internal pin configuration so the old key no longer operates the lock, and the locksmith provides new keys matched to the new configuration. Keys that are rekeyed to match each other are called keyed alike, which lets one key open several locks on the same property. Old keys will not work after a rekey, which is why it is useful after a move or lost key.
