Maybe try this function? I copied this from SA-MP wiki

pawn Код:

stock DisableVehicleAlarm(vehicleid)
{
    new engine, lights, alarm, doors, bonnet, boot, objective;
    GetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
    SetVehicleParamsEx(vehicleid, engine, lights, false, doors, bonnet, boot, objective);
}
