Hello @Matthew Zakrzewski
The duplicate computer name shouldn't prevent you from identifying the correct BitLocker key. Use the Recovery Key ID displayed on the BitLocker recovery screen rather than relying only on the computer name.
For an AD DS-joined device, an administrator can use Active Directory Users and Computers (ADUC) with the BitLocker Recovery Password Viewer installed. Right-click the domain and select Find BitLocker Recovery Password, then enter the first eight characters of the Recovery Key ID shown on the affected laptop. This lets you locate the matching recovery password even when multiple computer objects have similar or duplicate names.
Also check whether the device is hybrid/Microsoft Entra joined or Intune-managed, because its recovery key might be stored in Microsoft Entra ID or Intune rather, or in addition to on-premises AD.
If the correct recovery key cannot be found in AD DS, Entra ID, Intune, or another previously configured recovery location, BitLocker encryption cannot simply be bypassed or reset while preserving the encrypted data. That's an intentional security property of BitLocker. In that situation, if the existing data isn't required, the practical option is to wipe/reimage the drive and reinstall Windows.
Before doing that, I'd strongly recommend searching AD using the Recovery Key ID first, since AD can retain multiple recovery-password objects for a computer.
