I get this question a lot, and I love it — because it means someone is actually thinking proactively about their home security instead of waiting for something to go wrong. So let’s talk about How Often Should You Rekey Your Locks, and I’ll give you the honest, no-fluff answer. Whether you just moved into a place near Camelback Mountain, finished a renovation in Arcadia, or something shifted in your personal life, there’s a real answer here — and it’s simpler than most people expect.
There’s No Magic Number — But There Are Clear Triggers
A lot of homeowners assume rekeying is something you do on a schedule, like changing smoke detector batteries. It’s not quite that mechanical. The better framework is life events. Your locks should be rekeyed whenever the circle of people with key access changes — especially if that change wasn’t on your terms.
Here are the situations where rekeying isn’t optional — it’s urgent:
- You just bought or moved into a home. You have zero idea how many copies of that key exist. Previous owners, contractors, dog walkers, house sitters — all potentially still holding a working key.
- A relationship ended. If an ex-partner, former roommate, or estranged family member has a key, change your access situation before you change your Netflix password.
- A contractor or service worker had access. It happens to good people all the time in areas like North Phoenix and Paradise Valley — trades come through during a renovation, and keys get passed around.
- You lost a key and aren’t 100% sure where it went. That’s enough. Don’t talk yourself out of it.
- A tenant moved out of your rental property. No exceptions. Our guide on rekeying after an estate sale walks through a similar situation — the logic is the same.
The best time to rekey your locks is right after a life change. The second-best time is today — if you can’t remember the last time you did it.
How Many Times Can a Lock Actually Be Rekeyed?
This one surprises people. Most quality pin-tumbler locks — the kind on the majority of homes across Phoenix and the broader Phoenix metro — can be rekeyed many times without any degradation in performance. The process involves replacing the small pins inside the cylinder to match a new key. The lock hardware itself doesn’t wear out from rekeying. It wears out from daily use, weather, and time.
Where you do run into limits is with very old or low-quality hardware. If a lock is already worn, loose, or difficult to turn, rekeying is still possible — but it’s a good moment to assess whether a full lock replacement makes more sense long-term. Our rekeying service includes exactly that kind of honest assessment. We’ll tell you straight.
What a Rekey Schedule Might Actually Look Like for Most Homeowners
If your life is relatively stable — no major moves, no turnover of people with access — a reasonable baseline for most homeowners is every three to five years, purely as a precaution. That said, if any of the trigger events above apply, don’t wait for a calendar date. React.
For rental property owners in Mesa, Tempe, Gilbert, or Chandler with regular tenant turnover, every single tenancy change is a rekeying event. Full stop. It protects your property, your future tenants, and your liability exposure.

Ready to Rekey? Here’s What to Expect
Rekeying is fast, cost-effective, and typically runs significantly less than full lock replacement — usually somewhere in the range of $20–$50 per lock cylinder when a technician is already on-site, though pricing varies by lock type and quantity. We can often rekey every lock in your home to a single master key in one visit, which is one of those small upgrades that genuinely changes daily life.
