Is Rekeying Always Cheaper Than Replacing Your Locks?
August 16, 2026
The Assumption Most People Make
Ask most homeowners or business managers in Murray, Utah whether rekeying is cheaper than replacing locks, and the answer is almost always yes without hesitation. And in many situations, they are right. Rekeying is typically less expensive than a full lock replacement. But the word typically is doing a lot of work in that sentence, and there are enough exceptions to make the answer worth examining more carefully.
The real question is not which option is cheaper in the abstract — it is which option is the right choice for your specific situation, and what the actual cost difference looks like once you factor in the state of your hardware, your security goals, and how long you plan to stay in the property.
What Each Option Actually Involves
Understanding the cost difference starts with understanding what each service requires.
Rekeying
Rekeying changes the internal pin configuration of an existing lock cylinder so that a new key operates it and the old key no longer works. The lock hardware stays in place. A locksmith disassembles the cylinder, replaces the driver pins with a new combination, reassembles it, and cuts a new key to match. The process takes roughly 15 to 30 minutes per lock and requires no new hardware beyond the pins and the key itself.
Lock Replacement
Lock replacement removes the entire existing lock mechanism and installs a new one. This includes the cylinder, the lock body, the latch or bolt assembly, and sometimes the strike plate. It takes longer than rekeying, requires new hardware, and involves more labor. The cost of the hardware alone can range from $30 for a basic residential lock to several hundred dollars for a commercial-grade or smart lock.
When Rekeying Is Clearly the Better Value
Rekeying makes the most financial sense under a specific set of conditions. These are the scenarios where it is almost always the right call.
- You have recently moved into a new home or rental property in Murray, Utah and want to ensure previous key holders no longer have access.
- An employee left your business without returning their key and you need to eliminate that access quickly.
- You lost a key and cannot confirm it was not found by someone who could identify your property.
- You want all of your locks to operate on a single key — a locksmith can rekey multiple locks to one key during the same visit.
- Your existing locks are in good condition and less than seven to ten years old with no mechanical issues.
When Replacement Actually Makes More Financial Sense
There are situations where spending more on a full replacement saves money over time compared to rekeying hardware that should not be rekeyed. The following table breaks down the scenarios where replacement is the smarter investment.
| Situation | Why Replacement Beats Rekeying |
|---|---|
| Lock is worn, stiff, or failing mechanically | Rekeying a worn cylinder does not fix underlying wear. The lock will continue to fail and may need replacement soon anyway. |
| Lock is a low-grade or builder-grade model | Rekeying keeps a weak lock in place. Upgrading to a higher-grade lock improves security at the same time. |
| Hardware is visibly damaged from attempted break-in | A compromised lock body should be replaced regardless of whether the cylinder is functional. |
| Lock is more than 10–15 years old | Older locks may have worn components that make rekeying a temporary fix at best. |
| You want to upgrade to smart lock technology | Smart locks cannot typically be rekeyed — they require full installation. |
| Multiple locks need rekeying to different keys | If key control complexity is high, upgrading to a master key system or access control may cost similarly and serve better. |
A Realistic Cost Comparison in Murray, Utah
Costs vary depending on the locksmith, the hardware, and the number of locks involved, but the following ranges reflect what homeowners and businesses in the Murray, Utah area can generally expect.
| Service | Typical Cost Per Lock | Notes |
|---|---|---|
| Rekeying (residential) | $15–$30 | Plus service call fee, usually $50–$75 |
| Rekeying (commercial) | $20–$50 | Higher for complex cylinders or master systems |
| Lock replacement (basic residential) | $75–$150 | Hardware plus labor |
| Lock replacement (mid-grade) | $150–$300 | Better hardware, similar labor |
| Lock replacement (commercial grade) | $200–$500+ | High-security or specialty hardware |
For a homeowner in Murray, Utah rekeying three residential locks, the total cost including a service call is typically in the $100 to $175 range. Replacing those same three locks with mid-grade hardware could run $350 to $600. The savings from rekeying are real — but only when the existing hardware justifies keeping it.
Frequently Asked Questions
Can any lock be rekeyed, or are there exceptions?
Most standard pin tumbler locks can be rekeyed. High-security locks with restricted keyways, some European-style cylinders, and smart locks generally cannot be rekeyed in the traditional sense. A locksmith can assess your specific hardware and confirm whether rekeying is an option.
How long does a rekeyed lock last compared to a new one?
A rekeyed lock lasts as long as its hardware allows. The rekeying process itself does not affect the mechanical lifespan of the lock. If the hardware is sound, a rekeyed lock should perform identically to a freshly replaced one of the same model.
Can I rekey my locks myself to save money?
Rekeying kits are available for some lock brands and can be used by a patient DIYer. However, improperly rekeyed locks can result in keys that bind, pins that fall incorrectly, or a lock that fails to operate reliably. For most homeowners, professional rekeying at $15 to $30 per lock is worth the certainty.
If I buy new locks, can a locksmith key them all to the same key?
Yes. A locksmith can key multiple new locks — or a mix of new and existing locks — to operate on a single key. This is called keying alike and is a standard service that significantly simplifies key management for households and small businesses.
Does rekeying void my lock's warranty?
It depends on the manufacturer. Some lock warranties explicitly allow rekeying; others require it to be done by a certified technician. Check your lock's documentation or contact the manufacturer before rekeying if your warranty is a concern.
The Right Answer Depends on What You Have
Rekeying is cheaper than replacing locks — until it isn't. When your hardware is in good shape, rekeying is the smart, cost-effective choice. When the hardware has problems, rekeying a worn or inadequate lock is a short-term answer that delays a more expensive conversation.
The best way to get a clear answer for your specific situation is to have a locksmith assess the condition of your locks before recommending a path forward. In Murray, Utah, Lynn's Lockshop provides honest assessments without pressure toward unnecessary upgrades. Give them a call at
