Immobilizer issue (follow up)

I previously posted about a mystery where suddenly the car gave me a "security failure" and wouldn't start, though I was able to get it going again after disconnecting the battery. That was about two months ago, no problems since until today, where it happened again (with a different key). This time, disconnecting the battery did not seem to work. There was no pattern to the red light flashing, just about a minute of very fast flashes.
However, it mysteriously started after two or three failed attempts after I sat there for ten minutes cursing my fate.
I'm back to being extremely concerned by this problem, but still, there doesn't seem to be any good way forward. I saw a lot of suggestions about battery problems, but would that fit it suddenly deciding it didn't have a problem? Or is it likely some ruinous electrical issue.

novium, based on what you are describing, I would say the next time it happens, try to keep the key in the START position. Then I want you to try 2 things for me. The first is to simply move the key around inside the tumbler. Lift it up, push it down, move it front to rear, in circles, whatever direction you can think of to see if the car suddenly starts. If it does, then odds are you have a bad ignition switch. If the moving of the key does not make something happen, turn the key to the START position and with your free hand, move the gear shifter around and also try stepping on the brake and shifting the car to NEUTRAL as you are holding the key in the START position.
Lets see what you have at this point and then we can eliminate things and start narrowing the issue down some.

What's involved in replacing the ignition? Does it require a lot of computer stuff?

Novium, I think the question really is how easy is it to move the key around to get the car to start. if it is easy, then no big worries. Finding that sweet spot and tickling it just so, that may be a royal PITA. Replacing hte switch is not that bad from what I have read. Getting the part is not that expensive. Just have to take the time and do it.

When my car failed to start, at the E-Check inspection right in the lane, I had it towed home.
It turned out to be the electrical part of the switch. It comes off the mechanical part of the ignition switch very easily. Should be a 30-minute fix at worst case.
I pick one up off eBay for $10. I keep a spare in my toolbox to ensure it will never fail again.

On my cay, it blew a fuse and would not crank.
This is the part I replaced.

Low cost and easy to do.
