Rekey After Moving: 48 Hour Security Steps for Owners and Landlords
Yes, rekey your locks soon after moving in. Replace the hardware only when it is damaged, worn out, or a type that cannot be rekeyed. Before you unpack another box, check which keys you have, lock out anyone who shouldn’t have access, and get a rekey quote. This guide walks through costs, timing, DIY versus hiring a pro, and how to vet a locksmith safely.
TL;DR:
Rekey exterior doors the day you receive the keys or within 48 hours; finish garage and interior locks by the end of the first week.
Keep sound, rekeyable hardware; replace locks that are damaged, worn, unavailable for repinning, or being upgraded, while smart locks usually need digital recoding.
DIY suits a confident owner with one standard lock brand; hire a locksmith for mixed brands, master keyed systems, or uncertainty that risks cylinder damage.
Verify licensing and insurance before booking, get an estimate before work, check technician ID and company vehicle, and reject cash or app payment demands.

What rekeying means and how it differs from replacing a lock
Rekeying changes the inside of your lock cylinder so your old keys stop working and a new key takes over. A locksmith (or a motivated DIYer) removes the cylinder, swaps the pins and springs inside it, and cuts a new key to match the new pin combination. The outer hardware, the knob, lever, or deadbolt, stays exactly the same. According to This Old House, rekeying is often more affordable and faster than replacing hardware, though it won’t fix a lock that’s already damaged or worn.
Replacing a lock means pulling the entire unit out and installing new hardware. You’d do this when the lock itself is broken, outdated, or you want a style or security upgrade. Recoding a smart lock is a separate process again, usually done through an app or a reset code rather than a physical pin swap.
Not every lock can be rekeyed:
Standard pin-tumbler deadbolts and knobs from brands like Kwikset and Schlage are almost always rekeyable.
Smart locks and electronic deadbolts typically get recoded digitally instead of physically rekeyed.
Older or heavily worn locks, and some bargain hardware, may lack rekeyable cylinders entirely.
If you’re moving into a home with a smart lock, our guide on how to rekey a smart lock covers the differences in more detail.
Why rekeying after a move matters for security and liability
When you move into a new home, you inherit an unknown number of keys floating around that you can’t account for. Previous owners, their contractors, a real estate agent, a cleaning service, past tenants, even a neighbor who used to water the plants, may still hold a working copy. Rekeying is the only way to guarantee that every one of those keys stops working the moment you finish the job.
Landlords face a sharper version of this problem. Every tenant turnover is a liability moment: a unit with keys still circulating from a previous renter is a security gap and, in a dispute, a hard thing to defend. Rekeying between tenants is standard practice for exactly that reason.
Realtor.com recommends changing or rekeying locks at closing or within the first week of ownership, specifically to cut down the risk tied to unknown key copies. That one-week window is a useful deadline to hold yourself to, whether you’re a new homeowner or a landlord prepping a unit for move-in.
Prioritize in this order:
Front and back exterior doors first, since they’re the main entry points.
Garage entry doors and any side or basement doors next.
Gates and detached structures like sheds last, unless they lead straight into the house.

Rekey vs replace: costs, speed, and when to choose replacement
Rekeying is almost always the cheaper, faster option when the hardware is in good shape. Replacing makes sense when the lock is damaged, old, or a type that resists rekeying, or when you’re upgrading to a higher-security cylinder or an electronic lock. Our breakdown of rekey vs replace costs walks through local examples side by side.
A few things move the price: how many locks you’re doing at once, whether the brands match, and whether you want every door keyed alike (one key for the whole house) rather than keyed separately. Keying alike is the standard move for most homeowners, since juggling a different key for every door gets old fast after about day two.
Replacement is the better call when:
The lock is damaged, rusted, or the mechanism sticks or binds.
The hardware is old enough that rekeying kits or replacement cylinders aren’t readily available for it.
You’re upgrading security tiers, say from a basic deadbolt to a high-security cylinder.
You’re switching to an electronic or smart lock, which gets recoded rather than rekeyed.
American Home Shield notes that rekeying works well when the hardware is sound, but recommends hiring a locksmith instead of going the DIY route when your home has mixed lock brands or you’re not confident in your own skills, since a failed attempt can damage the cylinder. For a sense of what local rekey jobs typically run, our Homestead rekey cost guide breaks down pricing by job size.
How to rekey after moving: DIY, hiring a pro, and a realistic timeline
Rekey kits are sold at most hardware stores and are genuinely doable for a confident DIYer working on a single, standard brand of lock. American Home Shield points out that DIY kits exist, but recommends calling a locksmith when your locks are mixed brands, master-keyed, or you’re uncertain about the process, since a bad attempt can ruin the cylinder.
If you go the DIY route:
Remove the lock from the door and work with the cylinder in good light, ideally with the door propped open so you’re not locked out mid-job.
Use a factory-cut key rather than an aftermarket duplicate when rekeying, since mismatched cuts can cause the new cylinder to stick later.
If the lock was ever part of a master-key system, clear out every master pin. Leaving one behind means the old master key will still work, defeating the whole point of the job.
Reassemble, test with both the old and new keys, and confirm the old key no longer turns the cylinder at all.
Pro Tip: Test every rekeyed lock with the door open before you consider the job finished. A cylinder that sticks when the door is ajar will jam far worse once it’s load-bearing.
A professional visit moves faster and covers more ground. A locksmith typically starts with a quick walkthrough to count doors and check lock brands, then repins each cylinder on-site, usually in a matter of minutes per lock, and keys everything alike on request. Many visits also handle small add-ons at the same time: a sticking deadbolt, a loose strike plate, or duplicate keys for everyone in the household.
On timing, don’t let this slide. Get exterior doors rekeyed the same day you get the keys, or within 48 hours at the outside. Garage, gate, and interior locks can follow within the rest of that first week. That matches the window Realtor.com recommends for closing the gap on unknown key copies.
How to choose and vet a locksmith without getting scammed
A five-minute phone call before you book anyone weeds out most problems. Ask for the company’s full name, proof of license and insurance, a written estimate before work starts, a plain list of what services they cover, and a realistic arrival window. Our phone checklist for choosing a locksmith covers exactly what to ask in under five minutes.
When the technician arrives, confirm a few more things on the spot:
Ask to see ID and check that the vehicle has company markings, not a plain unmarked car.
Get the estimate in writing before any work begins, not after.
Walk away from anyone who pressures you to pay in cash, gift cards, or a payment app on the spot.
Never sign a surprise contract that wasn’t part of the original estimate.
The FTC warns that scammers frequently impersonate legitimate companies or local authorities, often using spoofed caller ID, and push victims toward gift cards or untraceable payment apps. A related FTC consumer alert flags the same pattern with fake law enforcement callers demanding immediate payment.
If someone contacts you out of the blue claiming to be from a company or government agency, don’t give out personal information. Confirm their identity by contacting the company or agency directly, using a phone number or website you know is real.
Always verify a visitor or caller through a number you looked up yourself, never one they give you, and never let an unverified worker into your home unsupervised.

FAQ
Is it cheaper to rekey or replace a lock?
Rekeying is almost always cheaper than full replacement, since it reuses your existing hardware and only swaps the internal pins. Replacement only makes financial sense when the lock itself is damaged or you’re deliberately upgrading to new hardware.
Does rekeying mean replacing the entire lock?
No. Rekeying leaves the outer lock and door hardware untouched and only changes the internal pin configuration so old keys stop working. A full lock replacement swaps out the entire unit, which is a separate and generally pricier job.
How much does it typically cost to rekey a lock?
Rekey pricing depends on how many doors you need done and whether you want them keyed alike, with our Car Lockout Services and related FAQ page offering a general sense of local service pricing. For an exact figure, request a quote based on the number and type of locks at your property.
What does Home Depot charge to rekey a lock?
Pricing at hardware store counters and big-box retailers varies by location and isn’t listed publicly in a fixed rate. Calling ahead or requesting a quote directly from the retailer or a local locksmith is the most reliable way to get a current figure for your specific locks.
