How to install CAUSTIC Unlock Key v9.2 on Android API 14+

Takes about 2 minutes. You'll need roughly 67.3 KB of free storage.

  1. Grab com.singlecellsoftware.caustickey_1.apk — hit the Download button above (67.3 KB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
  2. Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
  3. (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 832fcc336829553a…. Any difference means the file is corrupted or tampered — delete and re-download.
  4. Open the APK — tap the download notification, or find com.singlecellsoftware.caustickey_1.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
  5. Check the signer — the install screen will name the publisher. For this build it should read CN=ryximdr, OU=ryximdr, O=ryximdr, L=ryximdr, ST=ryximdr, C=ryximdr. If it doesn't match, cancel — you have the wrong file.
  6. Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as WARNING).
  7. Done — open CAUSTIC Unlock Key — tap Open on the install screen, or find the CAUSTIC Unlock Key icon in your app drawer.
Common install errors for CAUSTIC Unlock Key
  • "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.
