Every keypad code, to unlock all the locked doors and safes, in S.T.A.L.K.E.R. 2: Heart of Chornobyl.

As you explore the Zone in S.T.A.L.K.E.R. 2: Heart of Chornobyl you’ll come across many locked doors, safes, stashes, and more throughout the map. While some of these are side content and are missable if you aren’t actively looking for them, some are part of main quests, and thus you’ll need to be able to open them.

Moreover, it is very much worth it to open these doors and stashes as they are filled with useful loot such as ammo, healing items, weapons, etc. And you’ll need all the help you can get in S.T.A.L.K.E.R. 2.

Most of these are locked behind a keypad, into which you’ll need to enter a code. Gathering these codes can be a hassle and require elaborate exploration.

As such, we’ve compiled every keypad code below, so that you do not have to go through the trouble to find them yourself.
