Bit-Unlock - Unlock bitlocker drive.
Bit-UNLOCK is a service that allows users to unlock Bit-locked drives when they do not have the key.
Scenario 1: Currently, when updating the operating system or changing the motherboard of a Dell or other brand machine, BITLOCKER is enabled by default and the user is unable to access data.
Scenario 2: While upgrading the hard drive, it was also removed from the old laptop (unknown to the user – it is blocked) and inserted into the new laptop – data cannot be accessed.
In Both the Scenario user do not have the Bit-Locker Key. Check your Microsoft account to see if you have a bit locker key stored there.
If you go to Dell or Manufacturer, they will redirect you to Microsoft – Microsoft owns the BitLocker product. According to Microsoft procedures/documents, bit locker users should save the KEY or export to an online account.
