Hey all, new here obviously but used the awesome PDf to fix my key not turning issue. My new problem is that my key fob won't unlock the car remotely, it's 8 years old so I figured the battery's were just dead. I replaced them and it still doesn't remotely unlock the car and when I manually use the key it unlocks but the alarm goes off and when I try to start the car it fires right up then shuts down virtually immediately. Anyone go through this before and have suggestions? Thanks for any help in advance.
