what if... [same question just a bit different]

you and I were trapped in a small room and that we are sitting at opposite ends of each other. what separates us is the table in front of us above it lays a small blade.

the announcer in the speaker tells that there is a key to get out of the that room, but it is implanted in either you or me, then later on the person on the speaker tells you that you don't have the key within you and it is within me in a very specific part of my body...

where do you think it will be and what would you do?

the speaker later tells of a clue "it is already exposed, you just have to slice it open"
