#include <a_samp>
public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(PRESSED(KEY_SUBMISSION))
    {
        if(IsPlayerInAnyVehicle(playerid))
        {
            new vehid;
            vehid = GetPlayerVehicleID(playerid);
            new
            iEngine, iLights, iAlarm,
            iDoors, iBonnet, iBoot,
            iObjective;
            GetVehicleParamsEx(vehid, iEngine, iLights, iAlarm, iDoors, iBonnet, iBoot, iObjective);
            if(iEngine == 1) // Engine is on
            {
                SetVehicleParamsEx(vehid, 0, iLights, iAlarm, iDoors, iBonnet, iBoot, iObjective); // Turn it off
                return 1;
            }
            else // Engine is off
            {
                SetVehicleParamsEx(vehid, 1, iLights, iAlarm, iDoors, iBonnet, iBoot, iObjective); // Turn it on
