becuse you are checking if(IsPlayerInAnyVehicle(playerid))

and it will return false if player isnt in vehicle and its out side of vehicle

just do this

PHP Code:

CMD:lock(playerid, params[])
{
    static
        id = -1;
    if (!IsPlayerInAnyVehicle(playerid) && (id = (House_Inside(playerid) == -1) ? (House_Nearest(playerid)) : (House_Inside(playerid))) != -1 && House_IsOwner(playerid, id))
    {
        if (!HouseData[id][houseLocked])
        {
            HouseData[id][houseLocked] = true;
            House_Save(id);
            SendClientMessage(playerid, COLOR_WHITE, "You have locked your house.");
            PlayerPlaySound(playerid, 1145, 0.0, 0.0, 0.0);
        }
        else
        {
            HouseData[id][houseLocked] = false;
            House_Save(id);
            SendClientMessage(playerid, COLOR_WHITE, "You have unlocked your house");
            PlayerPlaySound(playerid, 1145, 0.0, 0.0, 0.0);
        }
    }
    else if (!IsPlayerInAnyVehicle(playerid) && (id = (Business_Inside(playerid) == -1) ? (Business_Nearest(playerid)) : (Business_Inside(playerid))) != -1)
    {
