Keeping your home secure is one of the top priorities for any homeowner. Whether you’ve recently moved into a new property, lost your house keys, or want to upgrade your security, rekeying your house is often one of the most cost-effective and reliable solutions. But how much does it actually cost to rekey a home?
This guide breaks down everything you need to know from average rekeying prices, to factors that affect cost, and tips to save money while improving your home’s safety.
What Does It Mean to Rekey a House?
Before diving into the costs, it’s important to understand what rekeying really means.
Rekeying involves adjusting the internal pins and tumblers inside your existing lock cylinder so that it works with a new key while rendering the old keys useless. It does not require replacing the entire lock — only the internal components are changed.
This process is performed by a professional locksmith and is a popular choice among homeowners because it’s:
- Faster than changing all locks
- More affordable than replacing hardware
- Just as secure when done correctly
When Should You Rekey Your House Locks?
You should consider rekeying your house locks in several common situations:
1. After Moving into a New Home
You never know how many copies of your keys exist from previous owners, contractors, or real estate agents. Rekeying ensures only you have access.
2. Lost, Stolen, or Misplaced Keys
If your keys are missing or stolen, rekeying eliminates the risk of unauthorized entry.
3. Tenant Turnover (for Rental Properties)
Landlords and property managers should rekey locks between tenants to maintain safety and prevent disputes.
4. Divorce or Breakups
In emotionally sensitive situations, rekeying helps secure the property and bring peace of mind.
5. Upgrading Home Security
If your home still uses outdated locks, rekeying can be an affordable part of your security upgrade plan.
Average Cost to Rekey a House
The average cost to rekey a house generally ranges between $80 to $250, depending on the number of locks and complexity of the job. However, the total cost can vary based on several factors, which we’ll explore below.
| Service Type | Average Cost Range (USD) | Description |
|---|---|---|
| Rekey one standard lock | $20 – $40 | Basic door knob or deadbolt rekey |
| Rekey per door (2 locks) | $40 – $80 | Includes both handle and deadbolt |

These figures are general estimates; actual prices may vary depending on your location, locksmith rates, and type of locks installed.
Factors That Affect the Cost to Rekey a House
1. Number of Locks
The more locks that need rekeying, the higher the overall cost. Most locksmiths offer package deals for multiple locks, which can reduce per-lock costs.
2. Type of Lock and Brand
High-security locks (such as Medeco, Mul-T-Lock, or Schlage Primus) require specialized tools and expertise, increasing the cost.
3. Labor Rates and Travel Fees
Locksmith rates can vary based on region. Urban areas or emergency services typically charge higher labor and travel fees.
4. Rekeying vs. Replacement
Rekeying is cheaper than replacing locks, but if your hardware is damaged or outdated, replacement may be more cost-effective in the long term.
5. Key Duplication
Most locksmiths include a set of new keys with rekeying, but extra copies will add a small fee (usually $2–$5 per key).
6. Time of Service
After-hours or weekend services often include emergency fees that can increase the cost by 50% or mor
Rekeying vs. Replacing Locks: Which Is Better?
| Feature | Rekeying | Replacing Locks |
|---|---|---|
| Cost | Lower | Higher |
| Security Level | Same as before unless upgrading pins | Can be upgraded with new hardware |
| Hardware Replacement | Not required | Yes |
| Key Compatibility | New keys only | New keys and locks |
| Ideal For | New homeowners, lost keys | Damaged or outdated locks |
If your locks are still in good condition, rekeying is the best option. However, if you want to switch to smart locks, keyless entry, or higher-grade ANSI-rated hardware, a full replacement may be worth the investment.
DIY Rekeying vs. Professional Rekeying
While some hardware stores sell DIY rekey kits, hiring a professional locksmith is often the better choice for several reasons:
Professional Locksmith Rekeying
- Guaranteed precision: Ensures smooth key operation and reliable lock function.
- Non-destructive methods: Avoids damage to lock cylinders.
- Security assurance: Professionals can check for wear, tampering, or lock damage.
DIY Rekeying
- Lower initial cost, but higher risk of error.
- Can void warranties if locks are damaged.
- Not ideal for high-security or complex lock systems.
For most homeowners, professional service provides better peace of mind, especially when securing an entire house.
How to Save Money When Rekeying Your Home
Here are practical ways to reduce rekeying costs without compromising security:
- Rekey all locks to one key – Request a single-key system so all doors open with the same key. It saves time and future rekey costs.
- Schedule in advance – Avoid emergency or after-hours rates.
- Combine services – If you need lock repair or deadbolt installation, bundle the services for a discounted price.
- Use a local locksmith – Hiring nearby professionals minimizes travel and service fees.
- Check for promotions – Many locksmiths offer discounts for new homeowners or multi-lock rekeying.
Additional Costs to Consider
While the main rekeying fee covers labor and key changes, there may be additional charges such as:
- Service call fee: Typically $30–$50 for the technician’s visit.
- Hardware upgrades: If a lock is too old or damaged, replacement parts may add $20–$100.
- Digital lock resets: Smart locks may require software or code reprogramming at an extra cost.
The Value of Rekeying for Home Security
Rekeying isn’t just about changing keys — it’s about protecting your home, family, and peace of mind. It’s a proactive step that ensures no one else has unauthorized access to your property.
By maintaining control over your key system, you eliminate vulnerabilities left behind by previous homeowners, contractors, or tenants. Combined with security upgrades like deadbolts, door reinforcements, or smart locks, rekeying forms the foundation of a strong home security strategy.
