Kwikset Lock Won’t Work After Battery Change: How To Troubleshoot

 

So here are some troubleshooting steps to try if your Kwikset Lock won’t work after replacing the batteries.

1. Check Whether The Batteries Are Properly Installed

So go ahead and remove the interior cover on your lock to access the battery pack. Next, remove the battery pack and check if the batteries are placed properly—based on the correct polarity. If not, remove the batteries and put them back in properly.

More so, ensure you use the recommended batteries. Almost all Kwikset Smart Locks use AA alkaline batteries—non-rechargeable. And ensure you don’t mix old batteries with new ones to avoid an undesirable operation.

Your Kwikset lock should work fine if you have used the right batteries and they are correctly installed.

  1. On the interior assembly of your lock, remove the battery cover and then remove the battery pack.

Final Thoughts

Changing the batteries on your Kwikset lock should help sustain a reliable operation. But if the reverse is the case (not working after replacing the batteries), first check that the batteries are correctly installed and make sure you’re using the right batteries.

As mentioned, lithium batteries are not recommended—so if you’ve used lithium batteries on your lock, remove them and replace them with high-quality AA alkaline batteries. This should help fix battery performance issues with your Kwikset lock.

And if you’re replacing the batteries after noticing a low battery alert on the lock, first press the Program button and button A for 5 seconds each before putting in the new batteries. This should solve the “not working after battery change” issue.
