"when you turn on the ignition the lcd will say security if a code is set." -- The word "SEC" shows up if you previously enabled the security system but you are not able to input the correct code after you re-set the battery, as in my case. "If not then the feature is disabled." -- true, as is now, after the dealership guy (permanently, I guess) disabled it (in minutes).
"where the info is how to do what the dealers do?" -- Of course it is not in the owners manual, or I would have done it long ago, or a car thief could do it and thus defeat the purpose of the system. I guess the info is in the dealership's secret manual! What I mean is, the owners manual tells you how to disable or change the security code, _if_ you have the current code. But if you don't, then you may need to ask the dealership to permanently disable it.
