I have only worked on a ferrari that required no keys, let alone this immobilizer.

But from my previous experience on imports, and vettes. it sounds like your car lost the memory of the remotes/code. I am not sure that you can reprogram on your own, as some cars require ecu access along with a code, while some its a simple ignition sequence

Whenever that happens on dad's it means the battery is dead. Just sayin'

Use the key code and the key in the ignition. If you aren't sure how check the owners manual. A real pain, especially if you have a zero in your code, but workable until you get the fobs working.

i think he means ignition learning sequence. its the sequence needed to reprogram the key.

also, any chance you can get a volt reading off the battery?

if the car wont start, start @ the powersource and work your way from there.
