Cadillac CTS 2003 Stuck In Anti Theft
Changed intake / valve gaskets , got everything
back together. Car drove fine all the way home ,
however it was shifting a little odd so I thought
maybe the ECM needed a little reprogramming , I
removed battery cables for a little while for about
30 minutes then I went outside and got in my car.
Without thinking I put my key in the ignition , then
remembered I had to connect cables. I connected
the cables, got back in my car and it said Anti theft
security on the screen. Engine will start but it wont
shift , key stuck in ignition. Fuel gauge doesnt
work. So I brought it to a GM mechanic , they
replaced anti theft module because they said it
wasnt getting any response, they replaced it and
put a new battery in as well. They programmed it
and no progress , nothing worked and I'm $700 in
now. Any advice or tips?
