i want to know if repalce or change the motherboard the bitlocker will be activited in recovery or no
Yes, you will need the recovery key to access the drive. The Bitlocker keys are stored in the TMP on the motherboard, so if you change motherboards, it would be like moving the drive to a different computer.
Great question and the answer Yes you will be required to enter the 48 digit recovery key associated with the instance of that BitLocker implementation as the TPM is no longer present.
Once you have unlocked the BitLocker-enabled drive via Recovery mode, you can simple disable BitLocker and re-enable to associate the drive with the new TPM present on the motherboard replacement or you can use the TPM MMC via tpm.msc and "Set the owner".
Hope this helps! Good luck!
