Change APK subscription key on Playstore

Question

Hi, I have an app on Google Play Store that was from another account and that went to my account, because it will not mess with it anymore and the customer asked us to work on the next version. The problem is this: when we go up the new APK it asks us to sign with the previous APK Keystore, but the other dev does not want to pass the Keystore (it makes sense, since it is his). I saw in the Google documentation that there is a way to put a new Store to sign with our key the next versions, but I could not understand very well how this process of submitting the new key there in the control panel of the Play Store works. If anyone can explain otherwise or make some material available I would be grateful.

I went through something similar a while ago, I lost a key to an app of mine. when you lose the key or do not have coce can Abir a call on google. for this follow the steps below:

Step 1: Generate a new private key and upload the certificate To generate a new upload key and register it, follow the instructions in the Android Studio Help Center. The new key needs to be different from the previous one.

Then export the certificate from the new key to the PEM format:

keytool -export -rfc -alias -file -Keystore

Step 2: contact the google support team Our support team only accepts key reset requests when they are sent by the Play Console account owner.

To contact our team, the account owner can fill out this form. You need to attach the upload_certificate.pem file.

You will receive an email when the new upload key is registered. After that, follow the above steps to update the key storage and registration on the API provider.
