Should You Rekey or Replace Your Locks? A Q&A Guide from Naples’ Trusted Security Experts

Home security decisions can feel overwhelming. One of the most common questions we hear at “A” Locksmith is: Should I rekey my locks or replace them entirely?

Here’s everything you need to know in a simple question and answer format, backed by over 50 years of trusted local experience in Naples, Bonita Springs, and Marco Island.


What’s the difference between rekeying and replacing a lock?

Rekeying changes the internal pins of your existing lock so old keys no longer work. You get a new key, but keep the same lock body.

Replacing a lock means removing the old hardware and installing a completely new lock with a brand new key.


When is rekeying the better option?

Rekeying is smart when:

  • You’ve just moved into a new home

  • You lost your keys or had them stolen

  • A roommate or employee moved out

  • Your keys are sticking or not turning smoothly

  • You want all your locks to match a single key

It’s a fast and affordable way to regain control over who has access to your home or business.


When should I replace my locks instead?

Replacing makes sense when:

  • Your current locks are damaged, rusted, or outdated

  • You want to upgrade to smart locks or electronic access

  • You’re changing from knobs to deadbolts for added security

  • You’re remodeling and want a style refresh

  • You want copy-proof keys or high-security hardware like Mul-T-Lock

Replacement is ideal if you want new features, a fresh look, or more durability.


Is rekeying secure enough?

Absolutely. Rekeying resets the key access completely. If done by a professional like our technicians at “A” Locksmith, it is just as secure as replacing the entire lock in most situations.

In fact, many high-end homes in Naples Park, Coquina Sands, and The Moorings opt for rekeying right after closing on a home to eliminate any question of who might have an old key.


What’s more affordable, rekeying or replacing?

Rekeying is usually more budget-friendly. It costs less because you’re only changing the internal mechanism, not the whole lock.

Replacing is more expensive because it includes the price of new hardware and installation. That said, it can be worth the investment if you want added features or improved aesthetics.


Can I rekey my locks myself?

While DIY rekey kits exist, we strongly recommend professional service. Proper rekeying requires precision tools and experience. One small mistake could leave you locked out or create a security risk.

Our background-checked, local team ensures every lock is secure and working properly, often in under an hour.


What do local experts say?

“As a former police officer, I’ve seen how easily break-ins happen because someone still had a working key. Rekeying is one of the smartest, fastest ways to take back control.”
— Andrew Blitch, Owner of “A” Locksmith and Naples Security Expert
