I had the same problem the other day.. First time in 7 yrs that I've owned her... I don't really know what fixed it since I try almost everything but I do remember I took the key off the ignition, shut the door and lock it them repeat the procedure backwards
Lamme know if it works for you!

I don't think you can disable that feature since is a module related deal unless you have a rotunda scan tool.. Try locking and unlocking the doors with the key on, I know it has something to do the order you did things(locked it first then shut the engine off then tried to get out with the doors being locked)

If you have a tilt wheel, move it in the other direction... I had the same problem with my 99, there is a wiring harness that gets damaged after a while from moving the tilt wheel...

Mine would only start when the wheel was down.
