Yes you can recover the key from that drive, unless it was flashed with the wrong key or all zeros, but there's no way to tell that without extracting it first. The power cable could have been plugged in upside down and fried it that way. You can send it off to have the key extracted from the SST chip, shouldn't cost more than $15 or so, or get the programmer and learn to do it yourself, then you can proceed with installing a new drive after getting the key that way. The only issue with that method is if that drive wasn't the original one you'll have a useless key, whereas if you jtag it (provided the dash version is low enough) that key will definitely be correct.
