Rekeying a home is typically a low-cost locksmith task that changes which keys fit which locks. The overall price varies by the number of locks, lock types, and whether a professional is hired. The cost to rekey a house generally ranges from around $100 to $1,000, with most standard jobs falling between $150 and $350 for a typical 3-4 lock scenario.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rekey per lock | $15 | $20 | $60 | Includes labor and standard pins |
| Service call | $0 | $60 | $120 | Some providers include within per-lock price |
| New cylinder hardware | $10 | $30 | $80 | Depends on lock brand and finish |
| Total for 3-4 locks | $60 | $150 | $350 | Typical residential setup |
| DIY cost (if supplies self) | $20 | $60 | $150 | Assumes buying pins and cylinders |
The Typical Price To Rekey A House By The Lock
Most homeowners pay a combined amount of $100-$300 for a standard 3-4 lock rekey, including labor and standard hardware. A locksmith usually charges a per-lock rate plus a service call. The per-lock price commonly ranges from $15 to $60, with most midrange jobs around $20-$30 per lock when the scope is straightforward. For a typical entry door, two deadbolts or one doorknob cylinder may count as separate locks. Labor time is often 0.5 to 1.5 hours for a small to medium home, depending on access and lock type.
Major Cost Components Behind a Rekey Job
Most quotes break down into labor, pin/tumbler hardware, and service charges. The following table shows common components and realistic ranges in USD for residential rekeying. Prices can vary by region and by lock brand.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor per lock | $15 | $20 | $60 | Usually 15-45 minutes per lock |
| Pins and cylinders | $10 | $25 | $70 | Included in some bundles |
| Service call | $0 | $60 | $120 | Some contractors waive with multiple locks |
| Additional hardware (new knobs/escutcheons) | $5 | $25 | $80 | Optional upgrade |
| Taxes/permit surcharges | $0 | $5 | $20 | Usually minimal |
What Variables Have the Biggest Effect on Final Pricing
Lock count, lock type, and access constraints drive most of the cost variance. For 3-4 standard residential locks, prices stay modest, but adding specialty locks or multipoint systems can push costs higher. A 2- or 3-point deadbolt system may require multiple pins and longer labor time. If doors sit in tight hallways or require trim removal, the price can rise by 20%–40% due to extra labor.
Regional Price Differences Across the United States
Prices can swing by region due to labor rates and supply availability. In urban markets or coastal states, expect the average price to be toward the upper end of the range, while rural areas or midwestern regions may land closer to the lower end. A single-lock rekey might be as low as $15-$25 in some zones, but the service call and travel time can push that upward in dense metro areas.
Smart Ways To Save Without Skipping Security
Carefully compare quotes and ask about bundled pricing for multiple locks. Options to reduce cost include scheduling during non-peak hours, requesting only essential hardware changes, and confirming if pins can be refreshed rather than fully replaced. If a homeowner has existing compatible cylinders, the cost can drop significantly. For some households, a DIY rekey with purchased pins and cylinders is feasible and can cut costs by 40% or more, provided the homeowner is comfortable with basic locksmith tasks.
When Rekeying Makes More Sense Than Replacing
For most aging but intact hardware, rekeying preserves current doors and frames and costs far less than replacing hardware. If locks are functioning and the finish is sound, a rekey typically costs a fraction of a full hardware replacement. Consider replacement if a lock is corroded, loose, or misaligned, or if a home security upgrade is desired beyond key changes. For reference, a new deadbolt or high-security cylinder can add $50-$180 per unit beyond the rekey price.
Watch For Hidden Fees Like Weekend Or Travel Charges
Additional charges frequently appear as service calls and weekend rates. Weekend, after-hours, or holiday service can add 20%–50% to base pricing. Travel distance also factors in; jobs in remote locations may incur a small surcharge per mile. Always confirm whether the quoted per-lock price includes travel time and whether there is a minimum call-out requirement.
Per-Unit Pricing And Bulk Discounts For Whole-House Rekeying
Bulk pricing often applies when rekeying many locks in a single visit. A typical scenario is 5-6 doors including entry doors, back doors, and interior doors with privacy locks. Expect per-lock discounts of 5%–15% when the contractor can complete the entire set in one trip. If a home owner purchases all cylinders in advance, some locksmiths offer additional reductions for materials bought through their shop.
How To Read A Rekey Quote: Quick Checklist
Verify per-lock price, service call, and included hardware. Look for a line-item breakdown showing labor hours, pins/cylinders, and any disposal or removal charges. Confirm whether the price requires the doors to be unlocked at the start and whether rekeying includes re-pinning the existing cylinders or replacing cores. For homes with smart locks or mortise systems, ask for a separate line item as those can involve higher costs.
Real-World Example Scenarios With Pricing
Scenario A: 3 standard doors in a suburban home with 3 basic knobs and 1 deadbolt. Average price around $150-$260, including service call and basic cylinders. Scenario B: 5 doors in a city row-home with two high-security cylinders and one deadbolt. Price range often $260-$520, reflecting extra labor and hardware. Scenario C: DIY-friendly homeowner in a rural area, purchasing pins and cylinders and performing rekey themselves. Expect $60-$120 in supplies, with no professional labor.
Price Summary At A Glance
For a typical 3-4 lock rekey in a standard U.S. home, expect total costs between $100 and $350 when hiring a pro, with $150-$250 as the common middle ground. If additional hardware upgrades or specialty locks are present, the total can climb toward $500-$700 for larger homes. DIY pricing can lower expenses but requires comfort with basic lock work.
