1. Initiating the Key Upgrade Request on Google Play Console The first crucial step is to inform Google Play of your situation. You'll need to navigate to your Google Play Console and initiate a "key upgrade" or "app signing key reset" request. This action tells Google that you need to replace your old, lost key with a new one. This is the official channel to begin the recovery process.
2. Generating a New Keystore in Android Studio After submitting your request, your next task is to create a brand new keystore in Android Studio:
- Go to Build → Generate Signed Bundle / APK
- Select Android App Bundle → click Next
- Click Create new…
- Choose a secure path, set a strong password, and define a unique alias
- 👉 Make sure you store this keystore and password safely this time!
3. Exporting Your New Key as a .pem File Using Keystore Explorer
After creating your new keystore, you'll need a specialized tool called "Keystore Explorer." This free, open-source utility allows you to manage keystore files.
- Open your newly created keystore file in Keystore Explorer.
- Locate your key alias within the keystore.
- Right-click on the alias and select the option to export the key in the
.pemfile format. This.pemfile is crucial for proving your ownership to Google.
4. Uploading the .pem File to Google Play Console
With your .pem file ready, return to the Google Play Console. You'll find a section where you can upload this file as part of your key upgrade or password reset request. This upload validates your new key and helps Google confirm your identity as the app owner.
5. Generating and Uploading a New App Bundle (.abb file)
Finally, once Google processes your request, you'll need to generate a new signed Android App Bundle (.abb file) using your new keystore.
- Crucially, remember to increment your app's version code in your
build.gradlefile. Google Play requires a higher version code for every new upload. - Generate the signed bundle using your new keystore.
- Upload this
.abbfile to the Google Play Console.
This entire process ensures that even if you face the daunting challenge of a lost keystore or forgotten password, you can successfully recover and continue to update and maintain your app on the Google Play Store. It might seem complex at first, but by following these steps carefully, you'll be back in control in no time!

Can You Recover a Completely Lost Keystore Without Google Play App Signing?
If you did not enable Google Play App Signing, recovery is almost impossible.
Google cannot verify or replace your key because the key is stored only on your local system.
This is why Google Play strongly recommends enabling App Signing for every app.
Common Mistakes Developers Make (Avoid These!)
❌ Keeping only one copy of the keystore
If the file gets deleted, you're stuck.
❌ Forgetting keystore password
Password managers like Bitwarden or LastPass solve this problem.
❌ Not enabling Google Play App Signing
Without this, Google cannot help you recover your app.
❌ Uploading the wrong PEM file
Always export from the new keystore you generated.
Final Thoughts: Don’t Panic — Everything Is Recoverable
Losing your Android keystore or forgetting your Google Play password is scary, but it does NOT mean your app is dead. With Google’s improved App Signing system, developers can safely recover and continue publishing updates without losing their identity or app ownership.
Follow the steps carefully:
✔ Request key reset
✔ Generate a new keystore
✔ Export PEM
✔ Upload PEM to Google
✔ Upload new AAB
You’ll be fully back in control of your app in no time.
