How does Bitlocker work on Surface Pro 4?

My Surface Pro 4 recently crashed while I was using it, and now I am unable to see anything on the display, or connect it to an external monitor. It seems to turn on and off with the power button (the Typecover lights turn on and off when the device is powered on and off), however I have no way of seeing or hearing anything or logging in to my device at all.

I've taken it to a Microsoft Store, and been told they aren't equipped to fix the issue and that they would replace it for me instead. The issue is that I did not back up my data, and so I'd like to attempt to remove the SSD and plug it into another machine to salvage it that way (assuming that the SSD is still working correctly). It's not under warranty anymore, but I understand that opening the Surface does void my ability to trade it in.

Which leads me to my question about Bitlocker: I do not have a Bitlocker Recovery Key listed for this device in my Microsoft account. From what I've read online, Bitlocker only activates on the Surface when you log into it through your Microsoft account, which it then sends the Recovery Key to your account automatically. I think that I might not have logged into my Microsoft account on this device when I was using it, as otherwise I'm guessing I would have a Bitlocker code listed for it? I'm just concerned that if Bitlocker is indeed active, if I remove the SSD I may not be able to access the files on it because I was never given a code on my Microsoft account. So I'm wondering if this lack of a code on my account might mean that Bitlocker was never activated on the machine during the setup process? Any information on how this process works on the Surface would be greatly appreciated. Thank you!
