- Secure Entry - Data cannot be accessed without the correct high-strength alphanumeric 8-16 character password. A password hint option is available. The password hint cannot match the password
Use PowerShell instead
In PowerShell, run Lock-BitLocker -MountPoint "E:", replacing E: with the target volume’s mount point. Microsoft documents this cmdlet for locking BitLocker-encrypted volumes. Microsoft Learn: Lock-BitLocker
Lock-BitLocker cannot lock the volume that hosts the operating system. The documented command-line example is for a data drive; do not assume you can lock the currently running Windows system volume. Microsoft’s Windows BitLocker operations guide lists Command Prompt tools, the BitLocker PowerShell module, and Control Panel among management paths, but the sources cited here do not provide a Control Panel-specific lock procedure.
If the volume is in use
PowerShell provides the -ForceDismount option to attempt to lock a volume even when it is in use. For example: Lock-BitLocker -MountPoint "E:" -ForceDismount. Use this only when needed: forcing a dismount can interrupt access to the volume. It is not part of the ordinary locking command. Microsoft Learn: Lock-BitLocker

Locking is different from turning BitLocker off
A lock prevents access to a protected volume until it is unlocked. It does not turn off BitLocker, suspend protection, or change the volume’s key protectors; Microsoft documents those as separate management operations. Microsoft BitLocker operations guide and manage-bde command reference
Automatic unlocking is also configured separately. For a data drive, manage-bde -autounlock -disable D: disables automatic unlocking, while the corresponding -enable option enables it. These settings control automatic unlocking; they are not substitutes for the lock command. Microsoft Learn: manage-bde autounlock
Unlock the drive when you need it again
Locking and unlocking are separate operations. Before locking a data drive you will need to reopen, make sure you have an applicable unlock method available. Microsoft documents manage-bde -unlock with either a recovery password or a recovery-key file; follow the command reference for the appropriate syntax and supply your own drive and recovery details.
