Is Rekeying Your Home Always Worth the Cost?
October 4, 2026
When a new set of keys lands in your hand — after a move, a breakup, or a security scare — rekeying is often the first thing a locksmith recommends. It sounds simple, affordable, and smart. But is it always the right move? The answer is more nuanced than most people expect, and understanding when rekeying genuinely earns its cost is the kind of knowledge that protects both your wallet and your home.
Rekeying is the process of changing the internal pin configuration of an existing lock cylinder. Instead of buying a new lock entirely, a locksmith adjusts the lock so that only a new key will open it. The old key — and every copy of it — becomes useless. The hardware stays in place. The only thing that changes is which key works. For most residential locks in good condition, rekeying typically costs between $15 and $40 per lock, with service call fees factored in depending on the provider. That price point is one of the reasons it is so often suggested. But price alone should not drive the decision.
When Rekeying Is Clearly the Right Call
There are specific situations where rekeying delivers direct, measurable security value. If you have recently moved into a previously owned home, rekeying is not optional — it is essential. You have no way of knowing how many copies of your keys exist or who holds them. Previous owners, real estate agents, cleaning crews, contractors, and neighbors may all have had access. Rekeying eliminates that uncertainty in a single appointment. The same logic applies if a roommate has moved out, a relationship has ended, or you have experienced a recent break-in where keys may have been taken. These are the scenarios where rekeying earns its cost without question.
When Rekeying May Not Be Enough in Murray, Utah
Here is where homeowners in Murray, Utah often make a costly assumption: rekeying is only as effective as the quality of the existing lock. If your current locks are decades old, show visible wear, use outdated pin configurations, or lack basic security features like anti-pick or anti-bump technology, rekeying those locks keeps the same vulnerabilities in place. You are changing who can open the lock with a key, but you are not addressing how easy the lock is to bypass without one. In those cases, a full lock replacement — combined with rekeying the new hardware — offers far better value despite the higher upfront cost. For residents across Murray, Utah and neighboring communities, a professional evaluation before committing to rekeying ensures you are solving the right problem.
The Real Cost Comparison: Rekeying vs. Replacing
Understanding the cost spread helps you make a cleaner decision. Rekeying a standard residential lock costs considerably less than replacing it. A basic lock replacement, including hardware and labor, can run between $75 and $200 depending on the grade of lock selected. Premium high-security locks can push that higher. So the question becomes: what is your lock worth saving? If your existing lock is a Grade 1 deadbolt in good working condition with no signs of wear or damage, rekeying is the cost-effective choice. If the lock is a builder-grade model installed years ago with no security certifications, replacement is the smarter long-term investment. Rekeying a lock that should be replaced is spending money on a problem that is not fully solved.
How Many Locks Should You Rekey?
Homeowners in Murray, Utah who are rekeying after a move sometimes make the mistake of only rekeying the front door. Every exterior point of entry — back door, garage entry door, side gate locks, basement access points — represents a potential vulnerability. A comprehensive rekey covers all of them and, where possible, sets them all to the same key for convenience. This is called keying alike, and a qualified locksmith can configure multiple locks to operate on a single key during the same appointment. It adds minimal cost and significantly improves daily usability while maintaining complete security. Lynn's Lockshop serves homeowners across Murray, Utah and the surrounding area, and recommends treating all exterior access points as part of a single security system rather than addressing them one at a time.
Frequently Asked Questions
Can I rekey my locks myself without a locksmith?
Rekeying kits are sold at hardware stores and can technically be used by a homeowner with patience and mechanical aptitude. However, a mistake during the process — such as installing a pin at the wrong depth — can result in a lock that is stiff, inconsistent, or completely non-functional. For most homeowners, the cost savings of DIY rekeying do not outweigh the risk of compromising the lock.
Does rekeying void a lock's warranty?
It depends on the manufacturer and who performs the rekeying. Some manufacturers void the warranty if rekeying is performed by someone other than an authorized locksmith. If your lock is still under warranty, review the terms before scheduling a rekeying appointment to understand whether professional service is required to preserve coverage.
How long does a rekeying appointment typically take?
A single lock typically takes a professional locksmith fifteen to twenty minutes to rekey. For a full home with multiple entry points, expect the appointment to run between forty-five minutes and ninety minutes depending on the number of locks and whether they are being keyed alike to operate on one shared key.
Can a locksmith rekey a lock if I do not have the original key?
Yes. A qualified locksmith can pick or decode the existing lock to gain access to the cylinder without the original key. There may be an additional charge for this step, but it does not prevent rekeying from being performed. The locksmith will confirm the lock is in suitable condition before proceeding.
Is rekeying effective against lock bumping or picking?
Standard rekeying does not improve a lock's resistance to bumping or picking — those vulnerabilities are tied to the physical design of the lock, not its key configuration. If bump or pick resistance is a concern, discuss upgrading to a high-security lock cylinder as part of your rekeying appointment.
Conclusion
Rekeying is one of the most practical security steps a homeowner can take, but it works best when matched to the right situation and the right locks. Not every circumstance calls for rekeying, and not every lock is worth rekeying. When you are unsure, a professional assessment saves you from spending money in the wrong direction. Lynn's Lockshop offers honest evaluations so you know exactly what your home needs — and what it does not. If you are weighing your options, reach out for a consultation before committing to anything.
