How to get your Bitlocker Recovery Key and regain access to your computer

Overview

Bitlocker is used to protect Windows hard drives from unauthorized access. When you plug in a new device to your computer (a USB device, a second hard drive, etc) Bitlocker may block access to your system as a protective action.

In order to get back into your computer when BitLocker locks your screen you need to use the recovery key. Even without plugging in a new device a BitLocker lockout can occur. Regaining access is easy with the recovery key. For MHC-owned computers, LITS can provide the key.  

Once recovered you will be able to use your computer but you will be asked for the recovery key every time you reboot. To avoid the computer ask asking for the recovery key at every restart, you should suspend and then resume BitLocker following the instructions below.

Steps

3. Select manage Bitlocker and choose the option to suspend Bitlocker
4. Restart the computer
5. The computer will reboot and Bitlocker will be suspended
