Best Practices for Rental Properties: Should You Change Door Locks Between Tenants?
When one tenant moves out and another moves in, one question often arises among landlords: should you change the door locks? While it may seem like an unnecessary expense, changing or re-keying locks is one of the simplest ways to protect both your property and your new tenants. Below, we’ll look at why this practice matters, how it affects security and compliance, and what options are available for landlords and property managers.
Why Changing Door Locks Matters
Changing door locks between tenancies isn’t just about peace of mind but also about accountability and safety. Even if previous tenants have returned all their keys, duplicates could still exist. Tenants may have shared spares with family members, cleaners, or tradespeople during their lease. Replacing or re-keying the locks ensures that only authorised individuals have access moving forward.
For landlords, it’s also a risk management decision. In the event of theft or damage, being able to demonstrate that locks were changed between tenancies can support insurance claims and tenant security obligations under property management standards.
What the Law Says
While Australian tenancy laws don’t universally mandate changing locks after every lease, they do require landlords to provide a secure, lockable property. For example, in most states, landlords must maintain functional locks and ensure tenants can feel safe. Some jurisdictions also state that locks should only be altered with mutual consent during a tenancy, so making the change after a tenant leaves is the simplest and most compliant time to do it.
It’s a best practice rather than a legal requirement, but one that demonstrates professionalism and care in property management.
When to Replace vs Re-Key Locks
You don’t always have to install entirely new locks. Re-keying is often the most cost-effective approach. It involves changing the internal pins so that old keys no longer work while keeping the same external hardware. This approach is ideal for landlords managing multiple apartments or properties.
Full lock replacement becomes necessary when the lock is damaged, outdated, or doesn’t meet modern security standards. This includes worn mechanisms, broken deadbolts, or old security doors that don’t align properly.
How to Replace or Change Door Locks
Replacing a door lock is generally a simple DIY task if you have the right tools. For standard door handles or deadbolts, you can remove the two mounting screws, slide the old lock out, and install the new one in its place. For security doors or sliding doors, you’ll need a lock designed specifically for those systems to ensure proper fit and function.
When upgrading to new locks, choose hardware that meets Australian Standards (AS4145.2). This guarantees strength and resistance against tampering or forced entry, important for rental properties where tenant turnover is frequent.
