It's all in the title. Is there any way to get my key now that I've opened everything in the crypt WITHOUT 'READING' the 2nd letter? Thanks.

It's not necessary, any door you open with a key remains unlocked.

I think he means the weird triangular amulet, which you should have picked up, even if you didn't know that's what you were looking for at the time.

The "key" is in fact an amulet, as Kreador mentioned. If you don't have it, then you likely missed a casket.

oops again. My Bad. I've done this one a bunch but not for some time: I forgot the last chamber in the crypt, where the nice shiny Amulet was waiting.

I think you meant the Crypt Key. Sorry...

On the other hand, I'm glad you found a solution to your problem!
