I am not in love with the poison mechanism. If you've got something better, I'd prefer that. I also do like the idea of being notified if it's triggered. I rather dislike surprises of that sort.
If you believe you can remove the door yourself, I shall leave it intact so that you can examine the lock as it is. Would that work for you? If so, I believe 3pm would be a good time for you to arrive.
