Resident Evil 2 Remake - ALL Key Item Locations and Puzzle Parts

Posted in re2

Welcome to the complete guide to ALL Key Item locations and puzzle parts in Resident Evil 2 Remake on PS4. This reference guide contains the exact map locations for all of the games important items which are essential for solving puzzles and opening locked doors.

In this guide you will find, among other things: locations for the 3 medallions, ALL key locations (Spade, Club and Diamond), keycards, bolt cutters, electronic parts, batteries, detonators, jewels and other tools. Basically, this list will give you precise building, floor and room locations for everything you need to complete the game. There will be minimal spoilers, minimal character references and no boss fights.

Given the vast size of the police department, the majority of the games puzzles and items are located there. Players should note that items are not always what they seem in RE2. The Examine option in the inventory screen should be used frequently to inspect (and rotate) items to uncover their true purpose. For example, the Bejeweled Box is a simple box before it's examined and rotated. The Combine menu option also plays a vital role, allowing players to mix two items together and produce something more elaborate. A good example of this is the Detonator which is constructed from an electronic part and a battery.

The list below will help to explain what each of the items are used for in the game. Once a Key Item has served it's purpose, players can discard the item from their inventory to reclaim space.
