{
    new iengine, ilights, ialarm, idoors, ibonnet, iboot, iobjective;
    GetVehicleParamsEx(vehicleid, iengine, ilights, ialarm, idoors, ibonnet, iboot, iobjective);
    switch(type)
    {
        case 0:{SetVehicleParamsEx(vehicleid, enable, ilights, ialarm, idoors, ibonnet, iboot, iobjective);}
        case 1:{SetVehicleParamsEx(vehicleid, iengine, enable, ialarm, idoors, ibonnet, iboot, iobjective);}
        case 2:{SetVehicleParamsEx(vehicleid, iengine, ilights, enable, idoors, ibonnet, iboot, iobjective);}
        case 3:{SetVehicleParamsEx(vehicleid, iengine, ilights, ialarm, enable, ibonnet, iboot, iobjective);}
        case 4:{SetVehicleParamsEx(vehicleid, iengine, ilights, ialarm, idoors, enable, iboot, iobjective);}
        case 5:{SetVehicleParamsEx(vehicleid, iengine, ilights, ialarm, idoors, ibonnet, enable, iobjective);}
        case 6:{SetVehicleParamsEx(vehicleid, iengine, ilights, ialarm, idoors, ibonnet, iboot, enable);}
    }
    return 1;
}

usage: for the doors,

pawn Код:

ToggleVehicleParamsEx(vehicleid,3,0);  // unlocks doors
    ToggleVehicleParamsEx(vehicleid,3,1); //locks doors
