Anti-Theft System plus oddities?

I will list the issues first and then go into detail:

1. Car turns over but doesn't start
2. Odometer reads only as dashes (e.G. )
3. There is no OBD communication when trying to connect to the computer
4. When the key is turned to the ON position, a groaning sound comes from the passenger side of the vehicle. It sounds like it is coming from the front passenger wheel-well area.
5. When no key is inserted, the theft light blinks normally, every couple seconds. When I insert a key and turn it to the ON position, the theft light blinks rapidly.

Now, I will list the solutions I have attempted:

1. I checked the battery and it is healthy
2. A locksmith checked my key to ensure the chip was functioning
3. I tried every online PATS reset method that I could find. This, notably, has worked to fix this problem in the past (at least the no-start + groaning sound problem. I cannot remember if the odometer read dashes and I did not check the OBD connection the last couple times this problem occurred.) So, the PATS reset methods have worked to fix this problem 4-5 times over a few year stretch, but none of those methods works this time.


From what I have found online, it sounds like a problem with the immobilizer minus the groaning sound. I have not found anyone with the combination of issues I am having. This is all the information I can think to give you currently. Let me know if you need additional info. Thank you!
