Hey neighbors! For Keypad audio concerns, checking the volume setting in your Ring app will be the best first step. Try also unplugging the Keypad and plugging back in.
As it looks like most have attempted the above steps and more, the next best step will be to reach out to our support team.
The same exact thing happened to me. After adjusting the volume settings in the app did not help, I contacted Ring Support; we removed the device from the app, did a factory reset, and added the device back and it still did not work. Ring is sending me a replacement keypad, no charge (with Ring+, you get extended warranty with no expiration). Overall, Ring is the greatest!
