Wall With Four Slots RE4 Remake Puzzle Solution and Key Location

Navigating the grand castle during Chapter 8 of Resident Evil 4 Remake leads players directly into the mysterious Bindery room. Inside this location, players encounter a locked mechanism known as the Wall With Four Slots that must be solved to advance the storyline.
Locating the Four Lithographic Stones
Before attempting to solve the puzzle, players need to gather four distinct Lithographic Stones scattered around the Bindery. Lithographic Stone A is already mounted into the puzzle frame when you arrive in the room.
Lithographic Stone B is resting on a nearby bookshelf or small table located to the left of the door. Lithographic Stone C can be found resting on top of a stack of books along the side wall.
Lithographic Stone D is stored inside a glass display cabinet in the corner of the Bindery. Players must smash the glass panel with a knife or firearm to retrieve this key item.
Matching Symbols and Shapes on the Puzzle Door
Once all four tablets are inserted into the frame, players can begin rearranging and rotating each piece. The trick door displays faded engravings that indicate the correct color, border shape, and emblem icon for each slot.
The top slot demands a red shield emblem set within a square border shape. Placing Lithographic Stone D at the top and rotating it reveals the proper red shield graphic.
The right slot requires a blue sword emblem surrounded by a square border. Lithographic Stone C should be placed on the right side and flipped to display the correct matching symbol.
Final Alignment to Open the Secret Passageway
The bottom slot must feature a blue chest armor emblem enclosed by a hexagon border. Players should assign Lithographic Stone B to the bottom position and rotate it accordingly.
The left slot takes a red helmet emblem inside a hexagon border. Rotating Lithographic Stone A in the left position completes the final step of the sequence.
When all four stones match their respective slots in both symbol type and border color, the doorway unlatches automatically. Players are then free to proceed through the opened wall into the hidden corridor beyond.
