Are you considering installing a smart lock for your home, but wondering how long the batteries will last? As a homeowner, knowing the average battery lifespan of your smart lock is essential to maintaining its efficiency and functionality.
Smart locks come in various types with different connectivity options, such as Bluetooth, Z-Wave, or Wi-Fi, which can affect battery life. Generally, Bluetooth and Z-Wave smart locks can last 1 to 2 years without needing new batteries, while Wi-Fi-enabled locks may only last 1 to 3 months before needing a battery replacement. However, factors such as usage, battery type, and connection quality can significantly impact battery life, making it crucial for you to be aware of these considerations when choosing the right lock for your needs.
To help you make a more informed decision, we’ll dive into various factors that contribute to smart lock battery life, so you can keep your home safe with a reliable and efficient locking system.

Factors Affecting Battery Life
In this section, we discuss different factors that influence the battery life of your smart lock.
Battery Type
The type of battery you use in your smart lock plays a critical role in determining battery life. Commonly used battery types are alkaline and lithium. While alkaline batteries are more affordable, lithium batteries last longer and perform better in extreme temperatures. It is worth investing in lithium batteries to extend the battery life of your smart lock.
Lock Usage
The frequency of your smart lock usage is another factor that affects battery life. The more often you use the lock, the faster the batteries will drain. Some smart locks are equipped with features such as LED indicators, audio alerts, and automatic re-locking. Turning off or minimizing the use of these features can help conserve battery life.
Environmental Conditions
Environmental factors, such as temperature and humidity, can impact your smart lock battery life. Batteries tend to drain faster in extreme temperatures or high humidity. Ensuring your smart lock is installed in a sheltered location and using weather-resistant hardware can help in maintaining optimal battery performance.
Average Battery Life of Popular Smart Locks
When choosing a smart lock, it’s essential to consider its battery life. Let’s explore the average battery life of a few popular brands and their battery consumption factors.
| Smart Lock Type/Brand | Average Battery Life | Key Factors |
|---|---|---|
| Bluetooth & Z-Wave Smart Locks | 1-2 years | Connection type, battery type, and usage |
| WiFi Smart Locks | 1-3 months | Connection type, battery type, and usage |
| August Smart Lock | 3-6 months | WiFi connection quality |
| Long-Lasting Battery Smart Lock | 1-2 years | Uses 4 AAA batteries and comes with a 9V backup charger |
Keep in mind that heavy use will likely shorten the lifespan of your smart lock’s batteries. Bluetooth smart locks tend to have a longer battery life, typically ranging from 10 to 20 months, due to their power efficiency and low power frequency. WiFi smart locks, on the other hand, may require more frequent battery replacements.
To extend the battery life of your smart lock, consider purchasing lithium batteries or using rechargeable lithium-ion and NiMH batteries. These options are more sustainable compared to alkaline batteries, which have a shorter lifespan and are less environmentally friendly.
Signs of Low Battery in Smart Locks
It’s essential to be aware of the signs that indicate low battery in your smart lock. Knowing these signs will help you promptly replace the batteries and avoid being locked out of your home. Here are a few signs to look out for:
Warning Notifications
Warning notifications: Most smart locks provide warnings before the batteries expire, either through a mobile app, email notifications, or a red light on the lock itself. Keep an eye on these notifications and take them seriously to avoid any inconvenience.
Slower response time
Slower response time: As the battery power depletes, you might notice that the lock takes longer to respond to your actions. If you find that it’s taking more attempts to open the door or the lock is lagging, it’s time to check the battery.
Low Battery Indicator
Low battery indicator: Some smart locks have a built-in low battery warning light that notifies you when the battery is reaching dangerously low levels. Make sure to replace the batteries as soon as you see this indicator.
Regularly monitoring your smart lock’s performance and paying attention to these signs will help you maintain its functionality and efficiency. Replace batteries as needed to keep your home safe and accessible.
How to Extending Battery Life in Smart Locks
Choosing the Right Batteries
Choosing the right batteries is crucial for extending the battery life in your smart locks. It is best to opt for lithium batteries, as they tend to last longer compared to alkaline batteries. Lithium batteries can help extend the battery life of a smart lock by up to 1-2 years for Bluetooth or Z-Wave enabled smart locks, while WiFi-enabled locks may last for 1-3 months.
Regular Maintenance
Performing regular maintenance can also help prolong the life of your smart lock’s batteries. Ensure that your lock is properly mounted and not loose on the door, as this can cause unnecessary strain on the batteries. It is also a good idea to periodically check and replace the batteries to ensure optimal performance.
In case the batteries are depleted, follow these steps: Remove the battery pack from the lock, take out the old batteries, insert a fresh set of 4x AA batteries into the battery pack, and slide the battery pack into the battery compartment of the lock.
Limiting Unnecessary Usage
Limiting unnecessary usage of your smart lock can help conserve battery life. Some smart locks allow you to customize their settings to disable non-essential functions such as LED lights, auto-relocking, and audio functionality. Disabling these features can help minimize battery drain and extend the overall battery life.
For example, if you own a Kwikset SmartCode 913 model, you can set switches #1, #2, and #3 to the OFF position to disable these functions. Switch #1 controls the LED light, #2 manages the auto-relocking feature, and #3 determines the audio functionality.
Conclusion
In summary, the battery life of your smart lock largely depends on the type of technology it uses for connectivity. For example, Z-Wave and Bluetooth-enabled smart locks typically have a battery life of 1-2 years. On the other hand, smart locks that connect directly to Wi-Fi may only last between 1-3 months.
It’s important to keep an eye on the battery indicators provided by the lock, such as LED or low battery signs, as this will help you stay informed about when it’s time to replace the batteries. Investing in lithium batteries can also extend the battery life of your smart lock.
Remember to factor in usage patterns and any additional features of the smart lock that may impact battery life. By maintaining your smart lock and replacing batteries as needed, you’ll ensure a secure and convenient access to your home.
