This guide outlines the exact locations of all lockers in the Resident Evil 2 remake, as well as the codes for opening them. They contain cartridges for various weapons; you will also receive the Unlock Master achievement.
Men's locker room (police station)
You can find this locker in the men's locker room on the second floor of the police station. Open the door and go straight ahead.
Locker on the third floor (police station)
To find the cabinet, all you have to do is climb the stairs next to the first cabinet and look at the shadow of the mannequin.
Control room (upper drain)
To find this locker, you must enter the room with the control panel in the upper sewer (you cannot miss it if you follow the path that leads above the cable car). Please note that before you can enter the correct code, you need to deal with the zombies.
