On a Thursday I had my transmission speed sensor replaced. On Friday, the very next day, I'm driving and the rpms start to bounce like crazy, soon after the car dies...It starts but does not crank and the theft light flashes fast on each attempt. I've tried another key, but to no avail.

Explain what "starts but does not crank" means because you can't start it without cranking it. Starts mean the engine is running and cranking means the starter is turning the engine.

Start by calling the shop and telling them. They should be able to run codes and see what is wrong.

Check your fuses, especially the ones related to the anti-theft system (under the dash).

I meant the opposite, it cranks but does not start lol...it doesn't turn over, basically. Fuses have been checked, as it is in the shop right now. There's no communication to the code machine. They are suspecting I have a bad computer, of course I've had no warnings of this - not sure if I would.
