Register Key Mapping
If you want to change the default key bind for all players, you MUST change it in the
configs/config.lua BEFORE starting the resource on your main server.We have started using the FiveM native called
RegisterKeyMapping FiveM Documentation. This removes the need for while loops checking every frame for keypresses, therefore allowing the resource to be more optimised. This FiveM native works by triggering the chat command it has been registered with when the keybind is pressed. This new method also allows each client to change their own key binds in-game. Example 
Open Gta5 settings > Key Bindings > FiveM.Once you have started the resource on your server for the first time, even if you change the key in the config.lua, it will not change for the players who have already joined. Although it will change for the players who join after you have changed it.
Option 1:
Option 2:
- Go to C:\Users[USERNAME]\AppData\Roaming\CitizenFX
- Open fivem.cfg
- Remove the lines with this resource name.
- Restart Fivem. Keybinds will be set back to default values set in the config.
- Firstly unbind the keys using the method above, disable the key in the config.lua and then you can rewrite the code to use the regular method of while loops checking for key presses
IsControlJustReleasedor other methods to trigger the events we provide to you in our docs.
- There is no way to mass unbind keys for all of your server's players.
