Custom Key System | JG Scripts Docs

If we don't support your key system out of the box, you can add your own.

Go to the framework folder, and open cl-functions.lua
Find the VehicleGiveKeys and VehicleRemoveKeys functions, which should look something like this:

function Framework.Client.VehicleGiveKeys(plate, vehicleEntity)
  if not DoesEntityExist(vehicleEntity) then return false end

  if Config.VehicleKeys == "qb-vehiclekeys" then
    TriggerEvent("vehiclekeys:client:SetOwner", plate)
  elseif Config.VehicleKeys == "jaksam-vehicles-keys" then
    TriggerServerEvent("vehicles_keys:selfGiveVehicleKeys", plate)
  elseif Config.VehicleKeys == "mk_vehiclekeys" then
    exports["mk_vehiclekeys"]:AddKey(vehicleEntity)
  elseif Config.VehicleKeys == "qs-vehiclekeys" then
    local model = GetDisplayNameFromVehicleModel(GetEntityModel(vehicleEntity))
    exports['qs-vehiclekeys']:GiveKeys(plate, model)
  elseif Config.VehicleKeys == "wasabi_carlock" then
    exports.wasabi_carlock:GiveKey(plate)
  elseif Config.VehicleKeys == "cd_garage" then
    TriggerEvent('cd_garage:AddKeys', plate)
  elseif Config.VehicleKeys == "okokGarage" then
    TriggerServerEvent("okokGarage:GiveKeys", plate)
  elseif Config.VehicleKeys == "t1ger_keys" then
    TriggerServerEvent('t1ger_keys:updateOwnedKeys', plate, true)
  else
    -- Setup custom key system here...
  end
end

function Framework.Client.VehicleRemoveKeys(plate, vehicleEntity)
  if not DoesEntityExist(vehicleEntity) then return false end
  
  if Config.VehicleKeys == "qs-vehiclekeys" then
    local model = GetDisplayNameFromVehicleModel(GetEntityModel(vehicleEntity))
    exports['qs-vehiclekeys']:RemoveKeys(plate, model)
  elseif Config.VehicleKeys == "wasabi_carlock" then
    exports.wasabi_carlock:RemoveKey(plate)
  elseif Config.VehicleKeys == "t1ger_keys" then
    TriggerServerEvent('t1ger_keys:updateOwnedKeys', plate, false)
  else
    -- Setup custom key system here...
  end
end

Inside the VehicleGiveKeys function, within the else block where it says

return 65 -- Setup custom key system here...

replace it with your custom give keys export. Also make sure you're providing the correct variables to the export based on the ones available:

plate - Vehicle plate
vehicleEntity - Physical vehicle entity

If you need to get the vehicle model/spawn code, you can use:

local model = GetDisplayNameFromVehicleModel(GetEntityModel(vehicleEntity))
If your key script can remove keys, do the same inside the VehicleRemoveKeys function, replacing the line that says

-- Setup custom key system here...

with the remove keys export of your key script. Again, make sure you're using the available variables, plate and vehicleEntity.
In config/config.lua, set Config.VehicleKeys = "none".
