The shotgun is powerful weapon that Leon can find pretty early on in the Resident Evil 2 Remake, but it's not as easy as just picking it up, of course. Instead, you have to find the weapons locker key card in another room and use it to open the locker containing the W-870 Shotgun.
Before we go any further, keep in mind that the shotgun is a Leon-exclusive weapon. Sorry to all of the Claire playthroughs out there—but not too sorry, seeing as Claire gets the Grenade Launcher instead.
So with all that out of the way, if you're wondering how to find the shotgun in Resident Evil 2 Remake, and the weapons locker key card, we take you through it below.
How to get the shotgun in Resident Evil 2 Remake
You'll find the shotgun as Leon in a weapons locker in the Safety Deposit Room on 1F of the RPD building in Resident Evil 2 Remake, which becomes reachable pretty early on.
The lockers there contain other items that you'll need to access from the terminal with the two missing keys—but the shotgun is the main item of interest in the early part of the game. It's in a weapons cabinet at the back of the Safety Deposit Room, opposite the entrance, but you can't open it without the key card.
Here's a map picture of the shotgun room's location for reference:

Where to find the Weapons Locker Key Card
To get to the weapons locker key card, you'll need to head to the Fire Escape on the far east side of the building, accessible from the first floor—you'll know you're there because it takes you outdoors. Take the staircase at the Fire Escape to the second floor, then walk through the corridor leading to the left until you find the Art Room on 2F. Enter. You'll find the weapons locker key card.
Here's a map of the Art Room's location so you can't miss it:

Alternatively, if you haven't got the shotgun yet but do have the Spade Key, you can reach the Art Room through the locked door in the Waiting Room, accessible from the second floor of the main hall.
The weapons locker key card looks like this:

From here, it's a simple matter of running back to the Safety Deposit Room and using the key card. You'll get the shotgun and some ammo for your trouble. Now you're ready to deploy some serious firepower in the Resident Evil 2 Remake.
