Existing door chime doesn't work after putting in battery

Hi! My existing door chime works just fine when I press my Doorbell 3 without battery in it, but as soon as I put it in, my existing door chime stops working. The chime works again as soon as I take out the battery. My notifications and everything work perfectly through our phones and Alexa, it just bugs me my existing chime doesn’t work, a little help here please! Thanks!

The best first step will be to ensure the Chime kit is compatible. Check out our Chime Compatibility lists to see if this chime kit is intended to work with your Video Doorbell.
