Google has updated the Play Console layout, making it difficult to find the key management options.

If you are stuck and cannot find the options in the sidebar, you can access the page directly by modifying the URL in your browser.

Step-by-step Workaround:

1. Navigate to your app in the Google Play Console. Your browser URL should end with /app-dashboard like this:

   https://play.google.com/console/u/0/developers/1234567890/app/0987654321/app-dashboard
   

2. Replace app-dashboard at the end of the URL with keymanagement:

   https://play.google.com/console/u/0/developers/1234567890/app/0987654321/keymanagement
   

3. Press Enter.

This will bypass the navigation menu and load the App signing page directly, where you will see the Request upload key reset section.

Make sure you generate a new upload key using keytool first, export it as a .pem certificate, and then upload it on this page.
