When Should You Rekey a Lock?

When we talk about home security, rekeying is one of the most overlooked but crucial steps you can take to protect your property and loved ones. Rekeying a lock means changing the internal pins and tumblers so old keys no longer work — essentially giving your lock a fresh start without replacing the entire hardware.

What the Experts Say About Rekeying

Security professionals widely agree that rekeying is a smart, proactive step every homeowner should take after a move or security concern. The National Crime Prevention Council recommends that “you should change or rekey your locks immediately when you move into a new home” to eliminate access from previous key holders. Similarly, the Associated Locksmiths of America (ALOA) advises that “rekeying is often the most cost-effective way to ensure your home’s security after a life event or key loss.” These industry leaders highlight what we see every day here in Naples: rekeying isn’t just a fix — it’s a powerful way to regain control over who has access to your most important spaces.

“As a former police officer, I’ve seen firsthand how many break-ins happen simply because someone still had a working key. Rekeying is one of the quickest, smartest steps you can take to secure your home — especially after a move or major life change. It’s peace of mind in under an hour.”

Why Should You Consider Rekeying?

Here are some of the most common — and important — reasons to rekey your locks:

1. You Just Moved In

Even if the previous owner handed over all the keys they had, you never know how many spare copies exist — contractors, cleaners, neighbors, or even relatives may still have access. This is true whether you have built a beautiful brand new home or purchased a vintage charmer.

“We moved into a beautiful home in Naples Park and didn’t think much of the locks at first,” said customer Angela D. “Then one evening, a neighbor knocked and said they still had a key from when they were pet-sitting for the previous owners. That was our wake-up call.”

2. Lost or Stolen Keys

It happens to the best of us. If you’ve misplaced your keys or suspect they were stolen, don’t take any chances. Rekeying your locks immediately gives you peace of mind. If you’ve inadvertently published a photo of your keys online, it’s a good idea to change them. Criminals can create keys from photos and have used them to break into homes.

3. Life Changes

Breakups, divorces, or even changes in household help (housekeepers, dog walkers, babysitters) are all moments when rekeying becomes essential. It’s not about distrust,  it’s about safety. They have no business having a copy of your key when it is time for them to go, you also can’t be sure how many copies may have been made.

4. Employee Turnover

For business owners in Naples and the surrounding areas, rekeying is a critical part of access control. If an employee leaves — even on good terms — it’s smart to update your locks or invest in a system like patented Mul-T-Lock keys or electronic access controls, which we install regularly for local businesses. Mul-T-Lock systems provide advanced key control so keys can’t be copied without you knowing. Many high end Naples homes have upgraded to this high security system for ultimate peace of mind. Smart locks lock out unauthorized users at the click of your app.

5. Your Keys Aren’t Working Smoothly

Keys wear out. If your key is sticking, slipping, or unreliable, it may be time to rekey — especially if your lock still has life left in it. A quick service visit can make it smooth and secure again. If you love the look of your lock, but the key isn’t working great, a rekey with some new pins and a fresh key can keep it functional a bit longer.

6. You Want More Control or Convenience

Sometimes people want to rekey to increase their security, but after doing somee research ultimately decide it’s time to upgrade to smart locks or install a master key system (popular with local HOAs and estate properties). It’s a smart move for convenience and elevated security.

A Personal Story: Why Rekeying Can’t Wait

“When I was a 11 years old, our family moved into a lovely home in the quiet gated golf community of Gulf Harbor in Fort Myers. Something happened that still makes my skin crawl. At around 2 am, we were jolted awake by the sound of our front door opening and a man stumbling over moving boxes and cursing.

A man, clearly intoxicated, had walked right into our home sending the whole family into a panic. He had already cut the phone line outside, and was shouting. He was angrily looking for his ex-wife, who had just sold us the home. Once he realized his mistake, he apologetically saw himself out, my parents called him a cab, and he proceeded to pass out on the lawn.

Thankfully, no one was hurt, but it could have ended very differently. He still had a key and used it to let himself in. My parents hadn’t rekeyed yet. That moment taught us, and hopefully reminds others, just how important it is to take control of your security. Maybe that home invasion changed the course of my life, inspiring me to help others secure their homes.”

“After a rough break-up, I felt uneasy knowing someone else still had access to my condo. A Locksmith helped me take that power back. They were so kind and professional, it felt like talking to a neighbor who truly cared.” — Laura P., Willoughby Acres

“Our teenager lost his key at school…again! Instead of replacing it for the fifth time, we had “A” Locksmith rekey the whole house and switched to a really cool keypad lock. No more hiding spares in the flowerpot! Plus we get a notification on the Schlage app letting us know he’s made it home safe from school, such a relief.” — Maria G., Naples FL, Riverstone
