My passport Ultra 1 TB (WD10JMVW-11AJGS2) SED with Password set

SITUATION:
As per client he has set the access password using WD UNLOCKER and the disk was working fine till the day it failed

SYMPTOMS AFTER FAILURE:
When this HDD is connected it does allow to access the WD UNLOCKER partition but when you run the UNLOCK Utility it says the drive is not locked so is the access to data area blocked.

ACTIONS :
I have converted this drive to standard SATA unblocked the SA access as its a SED using PC3K. Drives comes ready without any glitches. When i decrypt the data using PC3K it does find a key but when i am decrypting it with that it comes garbled / incorrect.
All the sectors are perfectly being read. there are no errors in the drive.
Anyone wants to take a look ?
Is there a missing link ?

Possibly somebody played with the KEY.
I am not an expert but what i understand is that the KEY does take Password into account.

i dont understand it correctly, can you please explain? garbled / incorrect

Did PC-3000 find more than one key? I believe that the one stored in the key sector near the end of the drive is changed when a password is set, however the one in the SA should be correct for the data. Unless of course they did a secure reset on the drive, in which case the one at the end combined with the password is the only way to decrypt it.
