How did Xehanort open that door?

[Puck]

I was playing KH2 and just read one of the final reports by the real Ansem The Wise. In one of them, he said he couldn't understand how Xehanort managed to open the locked door in the basement( I think that's what he said). Ansem didn't linger on the subject, which is kind of interesting. But he mentioned it like it was a really puzzling find. So how did Xehanort open the door? Did he use a key? Or some other type of power?

Ansem Report 5

To study the Heartless behavior, I picked one out for observation. It wiggled its antennae and, as if sensing a target, headed deep into the castle. In the deepest part of the castle, its antennae began vibrating, as if searching for something. Suddenly, a strange door appeared. I'd never known of its existence.

It had a large keyhole, but didn't seem to be locked. SO I opened the door. What I saw on the other side mystified me. What was that powerful mass of energy. That night I observed a great meteor shower in the sky. Could it be related to the door that I have opened?

^Oh, so that's how it happened. I didn't know that due to the fact I never really read all the Ansem Reports in KH1. I read a few but never Report #5.
