  2. Changes in LED color
  3. Voice prompt
  4. Beeping sound
  5. Flashing low battery icon

Solutions for Dead Battery

Here are some of the common solutions for your dead smart lock battery.

1. Replace the Batteries


The most common solution is a battery replacement. All you need to do is to find the battery compartment.

Some models would require a screwdriver to get into the battery compartment. However, for some manufacturers like Yale, you might need to use a tool with the smart lock or a pin to open the cover.

Some Kwikset models don’t even require any special tools to open the lock cover. You simply pull the cover to get to the battery compartment.

Once you find the battery compartment, remove the old batteries and replace them with new ones.

Make sure you are using the right batteries for your smart locks. For instance, Schlage smart lock and Vivint require alkaline AA batteries, while the August Wi-fi Smart Lock uses Lithium batteries.

2. Access the Mobile App


Another option is to access the system through your mobile app. Many smart door locks allow users to connect the system with a mobile application to shut it down in case their smart lock has no battery.

After shutting down the system, you can lock and unlock your smart lock using your door key.

Some smart lock systems like the Schlage Encode let users send virtual keys through email or text to family and friends that they can also use in case of a dead battery.

3. Override the System


If the options above don’t seem to work, you can try overriding the system to allow you to unlock your smart lock without triggering the alarm. However, you might need the user manual to do this properly.

If you don’t have the user manual handy, you can always call the manufacturer’s customer service to guide you with the override process and any necessary troubleshooting.
