Schlage Lock Draining Battery (Quick Ways to Fix)

If your Schlage Smart Lock is draining battery quickly and you’re not sure how to go about it, keep reading.

In this post, we’ll explain why this might be happening and what you can do to combat the problem. Let’s get started.

Schlage Lock Draining Battery

If your Schlage Lock is draining battery quickly, here are some reasons behind this issue:

  • You’re using the wrong battery.
  • Your Wi-Fi signal strength is weak.
  • Incorrect settings.
  • Wrong installation.
  • The lock is exposed to wind chills.

That said, let’s look at what you can do to fix this problem.

How to Troubleshoot a Schlage Lock that Drains Battery Quickly

Here are some steps to take to resolve this issue:

1. Check that You’re Using the Correct Battery

If you’re using lithium batteries in your Schlage Lock, that might be the cause of the battery problem.

All Schlage Electronic/Smart locks use non-rechargeable alkaline batteries. Check and ensure you have the correct batteries installed in your lock. See the recommended batteries for all Schlage Lock models.

If you have the correct batteries (alkaline batteries) installed in your lock and it still drains quickly, try the next fix.

2. Bring Your Router Closer to Your Schlage Lock

If you’re using a Schlage Lock with built-in Wi-Fi (Schlage Encode), weak Wi-Fi signal strength might be the cause of battery issues. And this usually happens if your router is positioned too far from the lock.

Since the lock has built-in Wi-Fi, it connects directly to your Wi-Fi network. And if the network signal is weak, the lock will continue searching and trying to connect to it, thus putting more pressure on the battery and reducing its life.

You can check the strength of the Wi-Fi network signal reaching the lock by viewing your Wi-Fi settings in the Schlage Home app. If the signal strength is weak, try bringing your router closer to the lock to improve it.

If you don’t want to move your router from its current location, try getting a Wi-Fi extender to boost your Wi-Fi network signals.

This should fix the battery draining issue with your lock. But if this doesn’t help, continue to the next step.

3. Restore Default Settings on Your Lock

Unseen glitches or incorrect settings may also cause your Schlage Lock to drain the battery quickly. And you can troubleshoot this by restoring factory settings on the lock.

So, if the battery issue persists, try restoring factory settings on the lock to see if it helps.

But before you reset your lock, note that this action will erase all your custom programming, so you’ll have to reprogram the lock after performing the reset.

That said, if you’re ready to reset your lock, see how to reset a Schlage Lock. If you have a Schlage Encode Deadbolt, see how to reset a Schlage Encode.

Your lock should work fine after performing the reset and reprogramming it.

4. Reinstall the Lock

Your Schlage Lock battery may drain quickly if the lock is not properly installed.

If your Schlage Lock developed the battery issue after you just installed it, chances are the installation is incorrect. Remove the lock from the door and reinstall it properly.

If you’re not sure how to install the lock, get a professional to help you or contact Schlage Support.

Final Thoughts

Cold weather may also cause your Schlage Lock battery to drain quickly—especially when the lock is exposed to wind chills. If this is the case, you may have to keep replacing the batteries in your lock during cold weather.

More so, if you have the Schlage Encode Wi-Fi deadbolt, ensure you disconnect the lock from your network whenever you turn off your Home Wi-Fi. If you don’t disconnect the lock when your Home Wi-Fi is turned off, the lock will keep searching for a signal and trying to connect, which reduces the battery performance.

So those are some troubleshooting steps to try if your Schlage keypad lock is battery drains quickly. If none of the fixes work, try contacting Schlage Customer Support for help.
