Do I Need Permission To Change Locks If I’m Renting?

Thinking about changing the locks in your rental but not sure if you’re allowed to? Whether it’s for peace of mind, after a flatmate moves out, or following a break-in, many tenants wonder what their rights and responsibilities actually are.

That’s why our team at A.Abbott Locksmiths has created this guide—to help clarify when you can change the locks, when you need permission, and what steps to take to stay on the right side of your lease. Let’s break it down so you can feel safe and secure without the confusion.

Can Tenants Change Locks Without Permission In NSW?

If you’re renting in NSW and thinking about changing the locks, you’re definitely not alone—it’s a common question, especially when security or privacy becomes a concern. But before you head to the hardware store or call a locksmith, it’s important to know your rights and responsibilities under NSW tenancy laws.

The short answer? You usually need the landlord’s consent before changing the locks. Under the Residential Tenancies Act 2010 (NSW), neither the tenant nor the landlord can alter, remove or add locks without the other party’s agreement, unless there’s a specific legal reason to do so.

That said, there are some important exceptions. For instance, if you’ve experienced domestic violence or there’s an urgent safety risk, you may have the right to change the locks without prior approval, but you’ll need to follow the correct legal process.

If you’re unsure, don’t guess. Reach out, check your lease, and get clear on where you stand. It’s your home too, and you deserve to feel safe in it.

Situations Where Lock Changes May Be Necessary

• Lost or stolen keys: If you’ve misplaced your keys or suspect they’ve been taken, changing the locks helps protect your belongings and peace of mind.

• Break-ins or attempted break-ins: After a security breach, replacing the locks is a smart step to restore safety and confidence in your home.

• Previous tenants still have keys: If you’re unsure who still has access, a lock change can give you back control over who comes and goes.

• Domestic violence or personal safety concerns: In NSW, tenants can change locks without prior landlord consent in urgent safety-related situations (such as domestic violence), as long as they follow legal procedures and provide the landlord with a copy of the new key.

Your safety comes first—don’t hesitate to act when your security is on the line.

Legal Responsibilities: Tenant Vs. Landlord

Thinking about changing the locks in your rental? Before you call in a locksmith, it’s important to understand your legal responsibilities as a tenant—and what your landlord is entitled to know.

Who pays for the lock change?

Generally, if you’re changing the locks for personal reasons (like lost keys or peace of mind), you’ll need to cover the cost. However, if it’s a result of damage, a break-in, or faulty hardware, your landlord may be responsible.

Who keeps copies of the keys?

Even if you’ve paid for the lock change, you’re still required to provide a copy of the new keys to your landlord or property manager—unless there’s a tribunal order that says otherwise.

What do you need to report? 

Any changes to the locks should be communicated to your landlord or agent straight away. Failing to do so could lead to a breach of your tenancy agreement.

If you need help navigating these obligations, an experienced locksmith in Sydney like A.Abbott Locksmiths can guide you through the process and ensure everything is done by the book.

Final Tips For Renters Changing Locks In Sydney

Before you go swapping out locks, here are a few smart steps to keep things smooth with your landlord and stress-free for you:

• Always get consent in writing. A quick verbal ‘OK’ won’t cut it if issues come up later—make sure it’s documented.

• Keep records of the lock change. Note the date, who gave approval, and what was changed.

• Notify your property manager as soon as it’s done. Don’t leave them guessing—it’s part of your responsibility as a tenant.

• Hang onto your locksmith receipt. It’s proof of the work done and might be handy when moving out.

• And if you need a reliable Sydney locksmith, A.Abbott Locksmiths is here to help with everything from key duplication to lock rekeying and full security upgrades.

Keeping it professional and transparent not only protects you but builds trust with your landlord—so everyone feels secure.
