Resident Evil 2 PS1 Claire part 2 of 11 Exploring the Police Station

The other side of the police station had a lot more zombies, I allowed them to go too close and got bit and close to dying, never liked that hall. Got to an office, lots of zombies there too, killed the ones that I had to and searched the place. Used a code that I had found on the safe, got some grenade ammo and a police station map. While not finding a whole lot of ammo, at least there are a lot of green herbs around here. I cleared the way to the interrogation room, but can't get to anything important just yet. I went back outside for some fresh air, and to recheck that area, okay, was nothing out here, went back inside. After some bit of wandering over the same places I've already searched I went back to the STARS office and read Chris' diary as well as finding a unicorn medallion laying underneath it. Back to the main lobby, placed the unicorn medallion at the statue, and it dropped a spade precinct key. With it I was able to enter the evidence room near where that licker is, and after pushing a stepladder over, climbed up to grab a crank from the top of one of the storage units. Okay, so I go back to the lobby to save my game, and wondering if I missed something as the doors that I see on the map are all locked.
