You just got the keys to a new place, and somewhere in the back of your mind is a question worth asking: who else has a copy of that key? A previous tenant, a past owner, a contractor, a real estate agent, a neighbor who used to water the plants. You don’t know, and that’s exactly the point.
This is one of the most overlooked steps after a move, and it’s also one of the simplest to handle. The real question isn’t whether you should do something about your locks. It’s whether you should rekey them or replace them outright.
Why Your Locks Matter the Moment You Move In
A new address doesn’t come with a guarantee that you’re the only one who can get in. Locks stay the same unless someone changes them, which means access from the previous occupant’s life can carry right over into yours. Taking care of this early, ideally before you’ve unpacked more than the essentials, closes that gap before it becomes a problem.
What Does Rekeying Actually Mean?
Rekeying means changing the internal pins inside your existing lock so that old keys no longer work, while a new key is cut to match. The lock itself, the hardware on your door, stays exactly the same. This is usually the faster and more affordable route, and it works well when your current locks are in good physical condition.
What Does Replacing a Lock Mean?
Replacing a lock means removing the old hardware entirely and installing a new lock in its place. This is the better option if your existing locks are old, damaged, low quality, or if you want to upgrade to something like a smart lock or a higher-security deadbolt. Replacement gives you a clean start on both the hardware and the key.
Rekey vs. Replace: How to Decide
There’s no single right answer here. A few questions can help point you in the right direction:
What condition are your current locks in?
If they’re solid, modern, and functioning well, rekeying is often all you need. If they’re worn, outdated, or already giving you trouble, replacement solves two problems at once.
Do you want to upgrade your hardware?
If you’re interested in a smart lock, a keypad entry, or a higher-grade deadbolt, that requires replacement rather than rekeying, since rekeying only changes what’s inside the existing lock.
How many entry points do you need to cover?
Front door, back door, side gate, garage entry. It’s worth thinking through every door that currently uses a key you can’t fully account for, not just the front entrance.
What’s your budget and timeline?
Rekeying is generally quicker and less expensive per lock. Replacement costs more but makes sense if your locks need attention anyway. A locksmith who can walk through your specific doors with you is often the easiest way to land on the right call without over- or under-spending.

Frequently Asked Questions
Is rekeying enough, or do I really need to replace my locks?
For most move-ins, rekeying is enough as long as the existing locks are in good shape. Replacement makes more sense if the locks are old, damaged, or you want new features like a smart lock.
How soon after moving in should I do this?
As soon as reasonably possible. Ideally before or within the first few days of moving in, so there’s no gap where an old key could still work.
Can you rekey multiple doors in one visit?
Yes. Most homes have more than one entry point, and it’s common to handle the front door, back door, and any additional locks in the same appointment.
Does rekeying work on all types of locks?
Most standard pin-tumbler locks can be rekeyed. If you have older or unusual hardware, it’s worth mentioning that when you call so we can confirm the right approach before we arrive.
What if I want a smart lock instead of a traditional key?
That requires replacing the existing hardware rather than rekeying. We can install smart locks as part of a replacement visit if that’s the direction you’d rather go.
