5 Signs It’s Time to Rekey Your Locks Instead of Replacing Them

When it comes to home or business security, many people aren’t sure whether they should rekey their locks or replace them altogether. Rekeying is a simple and cost-effective solution that involves changing the internal pins in your lock so the old key no longer works. At Jarrah Locksmith, we help Sunshine Coast locals make the right call — and in many cases, rekeying is the smarter option.

Here are five clear signs that rekeying your locks is the right choice.

1. You’ve Just Moved Into a New Property
Even if the previous owners, tenants, or property managers handed over all the keys, there’s no way to know if duplicates are still floating around. Cleaners, contractors, neighbours, or previous tenants may still have copies. Rekeying the locks ensures you’re the only one with access to your new home or business.

2. You’ve Lost a Key or Had One Stolen
If a key has gone missing and you’re unsure where it ended up, it’s best to assume it could be found and used by someone else. Rekeying your locks immediately disables the lost or stolen key, restoring your security without the cost of new hardware.

3. Someone May Have Copied Your Keys Without Permission
In rental properties or shared households, key duplication can happen without your knowledge. If you suspect someone has made a copy or if you’ve lent a key and didn’t get it back, rekeying is the best way to regain control without replacing your locks.

4. You're Going Through a Breakup or Changing Roommates
Personal and living arrangements can change unexpectedly. Whether it’s a breakup, a falling-out with a roommate, or simply someone moving out, rekeying ensures that only trusted individuals have access going forward.

5. You’ve Had a Staff Change at Your Business
In commercial settings, rekeying is a common and recommended security practice whenever there’s employee turnover. Whether someone was terminated or simply left the job, you should rekey the relevant locks to prevent unauthorized access to your business.

When Should You Replace the Locks Instead?
Rekeying is ideal when your locks are still in good condition. However, if your locks are outdated, damaged, or not up to current security standards, replacing them may be the better option. At Jarrah Locksmith, we can assess your existing locks and advise on the most secure and cost-effective solution.
