Smart locks offer unparalleled convenience by allowing you to control access to your home remotely and without physical keys. However, their reliance on battery power means you'll need to stay on top of battery maintenance. Fortunately, there are several very simple steps you can take to maximize your smart lock's battery life and reduce the frequency of replacements. 

In this post, we'll share our top 8 tips to help you get the most out of your smart lock batteries.

Do Smart Locks Run Out of Battery?

While smart locks are battery-powered and can potentially run out of power, they remain an incredibly effective home security solution. In fact, Lockly smart locks can still operate for up to 300 cycles on a low battery, ensuring your home stays secured even when the battery is running low.

The Lockly Vision Elite, for example, is an exceptional award-winning Video Smart Lock with a built-in solar panel that ensures your lock stays powered up, even during extended periods of use. Its advanced features and long-lasting battery life make it a top choice for homeowners seeking reliable and comprehensive home security.

1. Choose the Right Batteries

Using high-quality, name-brand alkaline batteries is crucial for optimal performance and longevity. Cheap, off-brand batteries may seem like a money-saving option, but they often have a shorter lifespan and can lead to reduced performance or even malfunctions. Always consult your smart lock's manual to ensure you're using the correct battery size and type for your specific model.

Lockly Secure models are powered by 4 AA batteries and our Vision model is powered by 8 AA batteries. We recommend using Duracell or Energizer, or any other good brand. We also don’t recommend using rechargeable or Lithium batteries as alkaline batteries have proven to work best with our locks.

As we mentioned above, it’s always helpful to use locks with advanced features like integrated solar panels to support those batteries.

2. Enable the Features You Need

Customizing your smart lock's features can also help extend its battery life. Start by going into the settings menu, where you can adjust your push notification preferences. Turn off any unnecessary notifications that you don't need to receive, as these can drain your battery over time. You can also enable or disable various switches and other settings to tailor the lock's functionality to your specific needs. By decluttering your smart lock's notifications and only keeping the features you truly use, you can optimize its power consumption and get the most out of its battery. Check your lock's settings or the accompanying mobile app to enable these features and start conserving battery life.

3. Reduce Unnecessary Access Attempts

Failed access attempts can quickly drain your smart lock's battery power. To prevent this, ensure proper alignment between the lock and door, keep the keypad clean, and consider using alternative access methods like the mobile app or a physical key if the keypad is unresponsive or the battery is running low. Lockly locks’ deep scanning also increases fingerprint accuracy to decrease these unnecessary attempts.

4. Maintain Proper Lock Installation and Alignment

Proper lock installation and alignment are essential for optimal battery performance. Friction caused by misalignment can significantly increase power consumption. Periodically inspect your lock and make any necessary adjustments to ensure smooth operation. Also, tighten any loose screws or mounting plates to maintain proper alignment.

5. Monitor Battery Levels and Replace Proactively

Regularly check your smart lock's battery level through the mobile app or built-in indicators. When the level falls below 20%, it's a good idea to replace the batteries proactively. This will prevent unexpected power failures and ensure uninterrupted operation. Always follow the manufacturer's instructions for proper battery replacement and disposal.

6. Protect Your Lock from Extreme Temperatures

Extreme temperatures can negatively impact your smart lock's battery life and overall performance. Install your lock away from direct sunlight, heat sources, or cold drafts. In harsh climates, consider using weatherproofing accessories like touchscreen covers or sealants to protect your lock from the elements.

7. Keep Your Lock's Firmware Updated

Regularly updating your smart lock's firmware is crucial for optimal performance and battery life. Firmware updates often include battery optimization improvements, bug fixes, and security enhancements. Check your lock's mobile app for available updates and follow the on-screen instructions to install them.

8. Keep a Strong Network Connection

A stable network connection is crucial for extending your smart lock's battery life. We recommend maintaining a strong Wi-Fi or cellular signal at all times. A weak or intermittent network connection can cause your smart lock to repeatedly search for a signal, draining the battery much faster. Ensure your lock is positioned within range of a reliable network access point, whether that's your home's wireless router or a stable cellular data network. With a consistently strong network connection, your smart lock can operate efficiently without constantly needing to reconnect, helping to preserve your battery life over the long run.

Stay On Top of Battery Maintenance with Lockly

By following these tips, you can significantly extend the battery life of your smart lock, ensuring reliable performance and reducing the hassle of frequent battery replacements. Stay on top of battery maintenance, enable power-saving features, and keep your lock's firmware up-to-date for a seamless and worry-free smart home experience.
