When Should You Rekey Your Home Locks?
Signs it's time to rekey, how the process works, and what it typically costs.
When Should You Rekey Your Home Locks?
Moving into a new home, going through a breakup, or simply losing track of who has a copy of your key are all common moments when a simple question comes up: should you rekey your home locks? Many homeowners assume the only options are living with the risk or paying to replace every lock on the house, but rekeying is often a faster, more affordable middle ground that most people do not know about until they need it.
This guide covers exactly what rekeying means, the situations where it makes sense, how it compares to full lock replacement, what the process actually looks like, and roughly what to expect to pay. Whether you are settling into a new home in Cleveland, Lakewood, Parma, Westlake, North Olmsted, Strongsville, Brooklyn, or a nearby community, this will help you make a confident decision about your home's locks.
What Does Rekeying a Lock Actually Mean?
Rekeying means changing the internal pins inside a lock so that your old keys no longer work, while a newly cut key does. The lock hardware itself, meaning the deadbolt, doorknob, or lever, stays exactly the same. Only the internal mechanism changes.
This is different from replacing a lock, which means removing the entire unit and installing a brand new one. Rekeying keeps your existing hardware and finish, which matters if you like the look of your current locks or want to avoid drilling new holes in your door.
How Rekeying Works, Step by Step
A locksmith removes the lock cylinder from the door
The internal pins are removed and replaced with a new, unique pin combination
A new key is cut to match the new pin arrangement
The cylinder is reinstalled, and all old keys immediately stop working
This process typically takes a locksmith 10 to 20 minutes per lock, which is one reason rekeying tends to cost less than full replacement.
Signs You Should Rekey Your Home Locks
Not every situation calls for immediate action, but a few common scenarios are strong signals that rekeying is worth doing sooner rather than later.
You just moved into a new home. You have no way of knowing how many copies of the key exist or who previously had access, including past tenants, roommates, contractors, or even a real estate agent's lockbox code.
You lost a key or had one stolen. Even if you are not sure whether it was lost or stolen, treating it as a security risk is the safer choice.
A roommate, ex-partner, or former employee moved out. Relationships and living situations end, but keys do not automatically stop working just because someone moved out.
You had contractors or repair workers with extended access. Anyone who had a key for an extended period, such as during a renovation, is worth accounting for.
You want to consolidate keys. If your front door, back door, and garage entry all use different keys, rekeying can often be done so that one single key opens all of them, which is a convenient side benefit.
Rekeying Versus Replacing: Which Do You Need?
Homeowners often assume replacement is the safer option, but that is not always true, and it is usually not necessary.
When Rekeying Is Enough
Rekeying is typically the right call when:
The lock hardware itself is in good physical condition
You like the current style, finish, and brand of your locks
Your main concern is who has access, not how the lock functions
You want a faster, lower cost solution
When Full Replacement Makes More Sense
Replacement becomes the better option when:
The lock is damaged, worn out, or difficult to turn even with the correct key
You want to upgrade to a smart lock or higher security grade deadbolt
The style or finish no longer matches your home's other hardware
The lock was compromised through forced entry or drilling damage
In most cases, if the lock still functions smoothly and you simply want to control who has access, rekeying solves the problem without the added cost of new hardware.
What Does It Cost to Rekey a Lock?
Rekeying is generally priced per lock rather than as a flat home fee, since homes have different numbers of exterior doors. While pricing can vary by location and the number of locks involved, rekeying is consistently less expensive than replacing the same number of locks with new hardware, since you are only paying for labor and a new pin set rather than an entire new unit.
If you are unsure how many locks your home needs rekeyed, a locksmith can walk your property with you and give you a clear, itemized quote before any work begins.
Can You Rekey a Lock Yourself?
Rekeying kits are available for purchase, and some homeowners with mechanical experience do rekey standard pin tumbler locks themselves. However, a few things are worth knowing before attempting it:
Losing track of small pins during the process is common and can leave the lock non-functional until reassembled correctly
Certain lock brands and high security cylinders require specific tools that are not included in basic consumer kits
If a mistake is made, you may end up needing a locksmith anyway, plus the cost of the kit already spent
For most homeowners, having a professional handle it takes roughly the same amount of time as doing it yourself, with far less risk of getting locked out mid-project.
How Often Should Rekeying Happen?
There is no fixed schedule that applies to every home, but a reasonable guideline is to consider rekeying:
Immediately after moving into a previously owned or rented home
Any time a key is lost, stolen, or unaccounted for
After any major change in who has regular access to your home
Every few years as routine security maintenance, even without a specific triggering event, particularly for rental properties between tenants
Rekeying for Landlords and Rental Properties
If you own a rental property, rekeying is not just a security nice-to-have, it is often close to a standard expectation between tenants, and in some cases a legal or lease requirement depending on your state and local regulations.
Why Landlords Rekey Between Tenants
Previous tenants may have made unauthorized copies. There is no reliable way to confirm every key was returned or that no copies were made during a lease.
It protects you from liability. If a former tenant or someone they gave a key to enters the unit after move out and something goes wrong, having documented proof of rekeying is a meaningful protection.
It is a selling point for new tenants. Being able to tell an incoming tenant that the locks were rekeyed specifically for them is a small but real trust builder.
Building a Rekeying Habit Into Your Rental Turnover Process
Many landlords and property managers build rekeying directly into their standard turnover checklist, alongside cleaning and repairs, rather than treating it as an optional extra step. Since rekeying is faster and less expensive than full replacement, it fits easily into a turnaround timeline without adding significant cost or delay between tenants.
If you manage multiple units, a locksmith can often batch rekeying across several properties in a single visit, which is worth mentioning when requesting a quote, since it may affect scheduling and pricing.
Choosing the Right Locksmith for Rekeying
Since rekeying involves someone accessing every exterior lock on your home, choosing a trustworthy locksmith matters just as much as the rekeying itself.
Confirm licensing and insurance where applicable. Requirements vary by state, but insurance protects you if anything is damaged during the visit.
Ask whether they can key all your locks alike in one visit. This is a common request and a good sign of an experienced technician if they can explain the process clearly.
Get a clear price per lock before work begins. A reputable locksmith can tell you the per-lock cost over the phone once they know your lock brand or door type.
Ask about same day availability. Rekeying is usually quick, and many mobile locksmiths, including Express Mobile Locksmith, can handle it the same day it is requested, often within the same visit as a lockout call if needed.
Check recent reviews specifically mentioning rekeying, not just general lockout service, since the two are related but distinct skills.
Taking a few minutes to confirm these details ahead of time means the work gets done correctly and your new keys are the only ones that matter going forward.
Frequently Asked Questions
Does rekeying work on all types of locks? Most standard pin tumbler locks, which are the most common type in residential homes, can be rekeyed. Some high security or specialty locks may require a locksmith familiar with that specific brand.
Will rekeying work with my existing key? No. The entire purpose of rekeying is that your old key stops working once the new pins are installed, and only the newly cut key operates the lock.
Can one key be made to work for multiple doors? Yes, in most cases. This is called keying alike, and it is a common request when a home has locks from different manufacturers or purchase times that originally used different keys.
Is rekeying enough after a break in? If the lock itself was damaged during a break in, replacement is usually the safer choice rather than rekeying, since a compromised lock body may no longer function or protect as intended.
How long does rekeying take for an entire home? For a typical home with three to four exterior locks, rekeying usually takes a locksmith less than an hour total, including keying all locks to work with a single new key if requested.
Do I need to be home for the rekeying appointment? In most cases, yes, since the locksmith will need access to each exterior door and will hand you the newly cut keys directly once the work is complete.
