Yale Unity Security Screen Door Lock Silver

Smart door locks give you keyless convenience and modern security. Here's how to choose the right one for your home.

1. Decide how you want to unlock your door

Smart door locks offer different ways to get in:

• Keypad/PIN code: Enter a code to unlock – simple and reliable, no phone needed.
• Phone app: Unlock with your smartphone via Bluetooth or Wi-Fi – convenient when your hands are full.
• Fingerprint scanner: Touch to unlock – fast and secure, best for families.
• Physical key backup: Most smart locks still include a traditional key option in case of battery failure or tech issues.

Choose based on what feels most natural for how you and your family come and go.

2. Think about who needs access

Smart locks let you create temporary codes for guests, cleaners, or trades that expire automatically. You can give kids their own codes and change them anytime. Some systems let you track who unlocked the door and when helpful for families with teenagers or rental properties.

3. Check battery life and power

Most smart locks run on batteries (usually AA or rechargeable) that last 6–12 months. Look for low-battery warnings that give you plenty of notice before they die. Some models have backup power ports so you can jump-start them with a power bank if batteries fail while you're locked out.

4. Make sure it fits your door

Check your door thickness (usually 35mm–45mm in Australia), backset distance (60mm is standard), and whether you have a deadbolt or latch. Some smart locks replace your entire lock, others fit over existing deadbolts. Measure before you buy to avoid compatibility issues.

5. Think about security features

Look for locks with:

• Auto-lock: Automatically locks after a set time – great if you forget to lock up.
• Tamper alerts: Notifications if someone tries to force the lock.
• Scramble keypad: Randomises the number layout to prevent people seeing which numbers you press.
• Australian Standards compliance: Check for AS4145 certification for peace of mind.

5. Consider installation

Some smart locks are DIY-friendly if you're handy with a screwdriver. Others need professional installation, especially if you're replacing the entire lock or adding new hardware. Check what's involved before you buy as installation can add $100–$300 to the total cost.

6. Set your budget

Smart door locks typically range from $250–$600+ depending on features, connectivity, and brand. Basic keypad models start lower, while full-featured locks with biometric scanning, Wi-Fi, and smart home integration sit at the higher end. Factor in installation costs if you're not doing it yourself.
