>did that peacemaker not have access to the infinite room?
He did. I didn't finish the first season, but in this episode we can see with the alien that the pocket dimension is accessible from multiple points, and Peacemaker stumbled upon alt-Peacemaker's door because of Eagley.
Since he's Peacemaker from an alternate reality, he has the same keypad and PIN.
His adverse reaction could be a result of alt-Peacemaker maybe being more evil compared to his counterpart, or him simply acting that way so the plot could happen.
A better question is if the pocket dimension can be accessed by anyone, why the fuck would you store anything remotely valuable there, like your entire collection of powered helmets?
