What Happens When Smart Lock Battery Dies?

If you’ve ever had your smart lock battery die, you know it can be a frustrating experience. Here’s a look at what happens when a smart lock battery dies and how you can avoid it.

What happens when the battery dies?

Smart locks offer convenience and security, but they can also have a few disadvantages including the battery dying out. But don’t worry, you can make sure your smart lock battery lasts longer. This can be frustrating if you’re trying to get into your home, but there are a few things you can do.

First, try to find a replacement battery for your smart lock. Many hardware stores or home improvement stores will sell batteries that are compatible with your lock. Once you have a new battery, simply insert it into the lock and you should be able to unlock your door.

If you can’t find a replacement battery, or if the new battery doesn’t work, you may need to reset your smart lock. To do this, consult the manual for your specific lock model. Each lock is different, but generally speaking, you’ll need to insert a small tool (like a paperclip) into a hidden hole in the lock. This will reset the lock and allow you to enter a new code.

Once you’ve reset your smart lock, be sure to choose a new code that is easy for you to remember but difficult for others to guess. That way, you can avoid this situation in the future!

How to change the battery in a smart lock

If your smart lock battery dies, you can easily change them. Learning how to change the battery on a keypad door lock is a quick and easy process. Here’s how to do it:

1. Start by unplugging the power cord from the back of the lock.

2. Next, remove the batteries from their compartment inside the lock.

3. To replace the batteries, simply insert new ones into the compartment in the same orientation as the old ones.

4. Once the new batteries are in place, reattach the power cord and plug it back into the lock.

5. Finally, test out the lock to make sure it’s working properly with the new batteries.

How to prevent a dead battery in a smart lock

If you’re using a smart lock, it’s important to know how to prevent a dead battery. Here are a few tips:

  • Make sure you have fresh batteries in your smart lock. If the batteries are starting to die, they may not provide enough power to the lock and cause it to fail.
  • If you have a backup key, use it occasionally to keep the mechanism lubricated. This will help prevent the batteries from dying.
  • Try to avoid extreme temperatures. If it’s too cold or hot outside, the battery may not work as well.
  • Check the battery level regularly and replace them as needed.


If your smart lock’s battery dies, you won’t be able to use it to unlock your door. However, most smart locks have a backup key that you can use to manually unlock the door. 

If you don’t have a backup key, you’ll need to call a locksmith or the manufacturer of your smart lock to get help getting into your home. In the meantime, make sure you keep extra batteries on hand so that you don’t run into this problem again!
