Just Cause 3 – How to Modify Keybind

Welcome to our comprehensive guide on how to modify keybinds in Just Cause 3. If you’re a gamer who’s played this action-packed title, you’ve probably experienced the frustration of the default key layout, especially when using gamepads. Fear not, for we have you covered with this guide.

Switching keymaps can be a game-changer, quite literally. The default key binds for gamepads can be challenging to navigate, and you may have found yourself accidentally killing your character with a grenade or crashing a plane. This guide aims to alleviate those frustrations by providing you with a step-by-step guide on how to modify your keybinds.

If you’re not interested in editing the keymap yourself, you can copy the same keymap that we’ve used in our playthrough, which is available here: https://pastebin.com/ExsWDx7w.

To modify your own keybindings, navigate to Documents/Square Enix/Just Cause 3 / [a long number] (for Windows users) and open the file named “keymap.txt.” You can use any text editor to modify this file.

How to Change Your Own Keybindings?

Each action that requires input is listed in the following format:


“action”: “LOOK_UP”,




“action”: “LOOK_UP”,



As you can see, each action is listed twice – once for PC keyboard input and once for gamepad input. To change the keybinds for an action, replace the name of the key within the quotation marks after “key:”. Be careful not to mix up gamepad buttons with keyboard keys.

The correct name for each button is already provided in the file, and you can easily search for the name of an action using “str+f.” Be mindful not to overload buttons accidentally, as this may lead to unintended behavior.

We hope you found this guide helpful in modifying your keybinds in Just Cause 3.
