SOLUTION 2018: Sign app with new keystore file if you missing password or lost jks file.

1) Create new keystore.jks file with comand line (not android studio build menu)

keytool -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks

Windows example:
"C:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore "C:\keystore_new.jks"

2) Generate a .pem file from new keystore

keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks

Windows example:
"C:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -export -rfc -alias upload -file "C:\upload_cert.pem" -keystore "C:\keystore_new.jks"

3) Use this support form, set "keystore problem" and with attachment add .pem file: https://support.google.com/googleplay/android-developer/contact/otherbugs

4) 12-48h you new keystore is enabled. Update your app on playstore with new apk signed with new keystore :D
