Whether you’ve just moved house, lost a set of keys, or your locks are starting to feel a little stiff, it’s not always clear if you should replace the whole lock or simply have it rekeyed. As trusted locksmiths servicing Melbourne and Geelong, we’re often asked: “Do I need a new lock, or can this one be fixed?”

In this guide, we’ll walk you through the practical signs that it’s time to replace or rekey your locks, so you can keep your home or business secure and stress-free.
What’s the Difference Between Replacing and Rekeying?
Before we get into the signs, let’s quickly explain the difference:
- Lock replacement means the entire locking mechanism is removed and swapped for a new one.
- Rekeying involves adjusting the internal pins of your existing lock so that it works with a new key. This means the old key no longer works, but you don’t need a brand-new lock installed.
Rekeying is usually more cost-effective and quicker, but it depends on your specific situation.
1. You’ve Moved Into a New Property
Whether it’s a new build or a rental, it’s impossible to know who still has a copy of the keys. Previous tenants, tradespeople, cleaners, even estate agents may still have access.
- Solution: We recommend rekeying all the locks when moving in, or replacing any that are outdated or not functioning well. It’s a small investment for long-term peace of mind.
2. You’ve Lost Your Keys
Losing your keys is more than just frustrating. If they’re found by someone who knows where you live, your security could be compromised.
- Solution: In many cases, rekeying is the best choice if the locks are still in good condition. But if they’re worn or low-quality, it’s safer to opt for a full replacement.
3. The Locks Are Old or Difficult to Use
If your key sticks, you have to jiggle it just right, or the lock feels rough when turning, it could mean the internal mechanism is wearing out. This is especially inconvenient for front doors or entry points you use every day.
- Solution: Old or worn-out locks are better off being replaced. New locks are not only more reliable but usually offer better security features.
4. You’ve Had a Break-In or Attempted Break-In
If someone has broken into your property or tried to, it’s critical to upgrade your locks immediately. Even if the intruder didn’t get in, any damage to the lock could leave you vulnerable.
- Solution: Replace any locks that show signs of damage or tampering. This is also a good opportunity to consider higher-security options, such as deadbolts or digital locks.
5. You Want All Locks to Use the Same Key
Carrying around a bunch of different keys can be annoying. If you want to simplify things, there’s a way to make multiple locks work with just one key.
- Solution: Rekeying is a practical option to standardise your locks. We can adjust them so you only need a single key for your entire home or business.
