Should I Change My Locks After Buying a House?

Last Updated: June 6, 2026

After months of searching the Brisbane property market, attending open homes, and navigating the buying process, you’ve finally secured your new home. Whether you’ve purchased a house in Mount Gravatt, Carindale, Sunnybank, Camp Hill, or elsewhere across Brisbane, moving day is an exciting milestone.

But once the keys are in your hands, an important security question often arises:

Should you change the locks after buying a house?

The short answer is yes.

Unless your property is a brand-new build, previous owners, tenants, tradespeople, cleaners, property managers, and even neighbours may still have copies of keys to your home. While most people are trustworthy, it’s impossible to know exactly how many keys are in circulation.

For complete peace of mind, many Brisbane homeowners choose to have their locks rekeyed or replaced as soon as they move in.

Why Rekeying Your Locks Makes Sense

Moving into a new home should be an exciting experience, not one filled with uncertainty about who might still have access to your property.

Rekeying is a simple and cost-effective solution that allows your existing locks to work with a brand-new key. Rather than replacing every external lock, a locksmith can modify the internal components of the locks so old keys no longer work.

Benefits of rekeying include:

• Immediate control over who can access your property

• Improved home security from day one

• A more affordable alternative to full lock replacement

• Reduced risk of unauthorised entry

• Greater peace of mind for you and your family

Many homeowners across Brisbane choose to have their locks rekeyed shortly after settlement to ensure they know exactly who has access to their property.

One Key for Added Convenience

When rekeying your home, you can also choose to have all external doors keyed alike. This means a single key can operate your front door, back door, side gate, and other compatible locks.

Having one key instead of several makes everyday life easier and helps eliminate the frustration of carrying multiple keys or accidentally grabbing the wrong one when you’re in a hurry.

What About Rental Properties?

If the home was previously used as a rental property, rekeying becomes even more important. Over time, keys may have been issued to multiple tenants, property managers, maintenance contractors, and service providers.

Even if all keys were supposedly returned, there is no guarantee copies were not made.

For this reason, many new owners arrange for rekeying shortly after settlement to ensure they are the only people with authorised access to their property.

Commercial Property Security

The same principle applies when moving into a new commercial premises.

Businesses often inherit unknown key histories from previous tenants, employees, contractors, and building managers. Without rekeying, there is no way to know exactly who may still have access.

Commercial rekeying helps protect:

• Office equipment and inventory

• Sensitive business information

• Client and customer data

• Staff safety and security

• Business continuity and operations

A professional locksmith can assess your current locking system and recommend the most practical and cost-effective solution for your premises.

Why Brisbane Home Buyers Should Consider Rekeying After Settlement

With Brisbane’s property market continuing to grow, many homes change hands multiple times over the years. In established suburbs, it’s common for properties to have had several owners, tenants, tradespeople, property managers, and contractors with access to keys at some point.

Once settlement is complete, rekeying your locks gives you confidence that only you and your family have authorised access to your new home. It’s a simple security upgrade that many Brisbane homeowners choose to arrange shortly after moving in.

Whether you’ve purchased a family home, townhouse, unit, or investment property, rekeying your locks is an affordable way to improve security from day one.
