Locked out of my PC! BitLocker was enabled on it's own and I have no key

New Contributor
Hi all,
This happened on my dad's Acer 5 A515 laptop. as far as I can tell - he just opened the laptop one day and was locked out of his PC with the Bitlocker screen on. He never enabled it or set up a recovery key, let alone saved the key somewhere. perhaps some rogue update behavior or smthng.
Is there anyway around that? what's important is to save some files that are on the PC - other than I can format and reinstall.

Do you remember if there was a setting enabled on your device called "device encryption"? It has a distinct name from BitLocker but internally it uses BitLocker and so the protection from BitLocker was likely always active even if you didn't realize it.

@amarioguyI don't know. It was just a new pc, bought a few months ago - nothing special was done to it at all... it just locked all of the sudden.

Hi @Ozo123123 

Please login to your Microsoft Account from another computer, Devices, select your device and click See detail, from Bitlocker data protection, select Manage recovery keys

@Ozo123123 if you sign in with a microsoft account on that locked PC, please do follow what SalmanAhmed said, the recovery keys get uploaded to the MS cloud (for device encryption) so you can retrieve the key you need to unlock the device
There's no recovery key there, I checked it already...

Hi @Ozo123123,

If you have done any hardware-level changes with your computer as mentioned below, I would suggest you to revert back the change, it will allow you to start your Windows. So that, you can turn off Bitlocker or you can take backup the key (If you want to keep Bitlocker): 

  • BIOS Configuration
  • Enable/Disable Secure Boot
  • Boot Order, UEFI to Legacy
  • TPM Disable/Enable
  • Add/Remove New Hard Disk/SSD


Additionally, I found a useful article, I hope it could be helpful for you.
