About the problem, your method of locking is right as long as you dispose the session but probably the bug lies under another part of your codes. by the way about the design, it is better that you pass the session variable to repositories because of unit of work implementation of the session and aggregate root's transaction like this:

using (ISession session = SessionFactory.OpenSession())
{
    Repository1 rep1 = new Repository1(session);
    Repository2 rep1 = new Repository2(session);
    Repository3 rep1 = new Repository3(session);

    // some logics

    using (var tx = session.BeginTransaction())
        tx.Commit();
}
