Smart locks offer incredible convenience—until they stop working. Whether it’s a dead battery, app glitch, or lock that just won’t budge, a malfunctioning smart lock can be frustrating and even leave you locked out.

If you’re wondering what to do if your smart lock stops working, don’t panic. In this guide, we’ll walk you through the most common causes of failure, how to troubleshoot safely, and when it’s time to call a professional.

Common Reasons Smart Locks Fail

Smart locks are built for ease of use, but like any tech, they’re not immune to issues. Understanding the common reasons they fail can help you diagnose and fix the problem faster.

1. Dead Batteries

Most smart locks run on AA or lithium batteries. If your lock becomes unresponsive, this is often the culprit. Ignoring low-battery alerts can leave you stranded—especially in Perth’s warmer months, where heat can drain batteries more quickly.

2. Connectivity Issues

Bluetooth and Wi-Fi locks depend on stable network connections. If your internet goes down, the lock may lose remote access or stop responding to app commands. Router resets or interference from other devices can also cause disruptions.

3. App or Firmware Glitches

Outdated lock apps or interrupted firmware updates can freeze or disable your lock. Sometimes even simple changes—like a phone software update or revoked app permissions—can stop the lock from syncing correctly.

4. Mechanical Misalignment

If your door has shifted slightly, the lock’s bolt might not align with the strike plate. This mechanical issue can jam the lock, even if the electronics are working fine. Seasonal expansion or poor installation are common causes in Perth homes.

5. Incorrect Credentials or Lockouts

Entering the wrong PIN or fingerprint too many times can trigger a lockout delay or disable access. Some locks have built-in protection features that freeze the system temporarily after repeated failed attempts.

6. Environmental Factors

Harsh sunlight, rain, or salty coastal air (common across Perth suburbs) can damage both the electronics and physical parts of your lock over time, especially if the lock is exposed without shielding.

DIY Troubleshooting Steps

Before you call in help, try these steps to get your lock working again:

Replace the Batteries

Even if the app shows battery life remaining, try replacing them. Some locks don’t report battery status accurately when power is low.

Try the Manual Key Override

Many digital locks include a physical key override—check your model’s instructions. Keep this backup key in a secure but accessible location.

Restart the Lock and App

Restart both your smart lock and the associated mobile app. Sometimes a simple reboot resolves syncing issues.

Reconnect to Wi-Fi or Bluetooth

Go into the app settings and re-establish the connection. If your Wi-Fi was down, ensure it’s back up and that your phone is connected.

Avoid Brute Force

Don’t force the lock or handle—it could damage the motor or internal components.

Factory Reset (with Caution)

If you’ve tried everything and the lock still won’t work, refer to the user manual for a factory reset process. Be aware this may wipe all stored data and settings.

If you’re still stuck, it’s time to call in a pro.

When to Call a Professional Locksmith

There are times when a smart lock failure goes beyond DIY fixes. You should call a licensed locksmith if:

You’re locked out and don’t have a backup key

Preventing Future Smart Lock Failures

Avoid being caught out again by taking these proactive steps:

• Change batteries every 6–12 months or sooner if usage is high
• Enable low battery alerts in your smart lock app
• Keep your firmware and apps up to date
• Use weather-resistant models if your lock is exposed to the elements
• Store backup keys securely for emergencies
