KEY_FIRE on foot isn't the same as in a vehicle. And you did several unnecessary things. I fixed the nos one but I don't know what the alt key is while in a vehicle. You will need to find that one out.

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if ((newkeys & 1) == (1))
    {
        new vehicleid = GetPlayerVehicleID(playerid);
        if(!IsPlayerInInvalidNosVehicle(playerid, vehicleid))
        {
            AddVehicleComponent(vehicleid, 1010);
            return 1;
        }

        if(IsPlayerInAnyVehicle(playerid))
        {
            new Float:ZAngle,vehicleid = GetPlayerVehicleID(playerid);
            GetVehicleZAngle(vehicleid,ZAngle);
            SetVehicleZAngle(vehicleid,ZAngle);
            return 1;
