I understand all of that very well. the point I was trying to make is that disabling the Smartkey system is also one those "dealer only" settings that you are led to believe can only be changed by dealer connected equipment. In fact, it turns out that it can be controlled by a fairly complex and obscure procedure that involving opening and closing the driver door in between clicks of the button on the remote.

Given that the Toyota engineers came up with that one, I suspect that at least some other of these settings can also be controlled by equally obscure "secret" button or switch sequences.

Look also to the entry method for the Nav system diagnostic screen for another example of a hidden sequence (and yes, I know it's made by Denso, not Toyota).
