When was the last time you changed the keys to your home or business? If it’s been more than five years, it might be time to think seriously about upgrading your security.

For residents and businesses across the Northern Beaches and North Sydney, key longevity is often overlooked. Many assume that as long as a key turns in the lock, all is well. But over time, keys can wear down, duplicate copies can fall into the wrong hands, and security standards can shift. What starts as a small oversight can result in serious security gaps.

The Hidden Risks of Old Keys

Like any frequently used tool, keys are subject to wear and tear. The more a key is used, the more likely it is to become misaligned or damaged. Over time, this can put strain on the lock mechanism, making it more susceptible to jamming, breakage, or even forced entry.

But physical wear isn’t the only issue. In five years, think about how many people may have had access to a copy of your key—whether it’s housemates, tenants, contractors, cleaners, or even previous owners. If even one of those copies is floating around unaccounted for, your security could be compromised.

Changing your keys at regular intervals (ideally every five years) is a proactive and affordable way to protect your home or business. It sends a clear message: your security is up-to-date, and you’re serious about controlling access to your property.
