Valet mode - How do you disengage?

What is your question?

The valet mode on my 1998 XK8 will not disengage. I have called around and searched the internet but have yet to find an answer. Unlocking the truck via the keyhole between the "X" and "K" at the rear of the car did not work. Neither did starting the car and trying to pop the truck using the dash button. I am using the black key and do not have the green valet key. When I press the valet button the message is "valet mode" but it appears this button does not disengage the mode.
