Sadclown,
You helped me -- I did not know what the valet switch was so I "Googled" it and there was a youtube of the similar problem in the search results (
) -- titled, "SC300/SC400/LS400/GS300/GS400/GS430 DIY - If Your Trunk Lock Button doesn't work". It appears that I must have accidentally pushed in the locking button between the electronic gas door and trunk release buttons. I unlocked it with my key and "viola". Unfortunately, in the video they did not have the original key just the valet key, so my solution was much simpler. Thank you and all who responded to my plight -- your responses guided me to the correct answer.
Sincerely,
