OK, I love the Holiday Innn joke...
But, you will at least need the programming manuals and a lot of time. I would recommend getting in touch with one of the Toshiba moderators (SSPhone, Martin, Keuklavy (sp?)) and pay them to work with you on the telephone. It will be much cheaper than having a tech drive out and might possibly save your sanity.
Toshiba programming is not easy if you do not have any experience with it.
