This is the better system and I used it in my server:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(IsPlayerInAnyVehicle(playerid) && GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
        
        if ((((newkeys & (4)) == (4)) && ((oldkeys & (4)) != (4)))) AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
        else if ((((newkeys & (4)) != (4)) && ((oldkeys & (4)) == (4)))) RemoveVehicleComponent(GetPlayerVehicleID(playerid), 1010);
    }
    return 1;
}
