Keyfob or other issue?
My wife has a 2008 v6 G8. Her keyfob has been wearing out, to the point that the rubber over the buttons is like.. shredded. So, she's been manually locking and unlocking the door, had no problem doing that for about a week. Starting yesterday evening, everytime she unlocks the car, there's power, as the alarm is active (makes the short beeps before she puts the key in) and all lights work and everything. As soon as she goes to turn the key, it cuts all power and locks her key in. When she manually opens the trunk, it releases the key, but doesn't restore power. When she gets it jumped, starts right up and drives fine, no power issues whatsoever... But the second she pulls the key out, sometimes cuts power again, or else it does when she goes to restart.
Is it possible that, because the keyfob is breaking down, the car might be cutting power as an anti theft feature because it doesn't recognize her chip? I'm so confused and so is everyone I've talked to, but they seem to agree it MIGHT be because of that, but have never heard of it... Or am I looking at a completely different issue? Tight on money, so kind of worried about having to go get a new keyfob. My coworker just had to replace his and it was over $160 because of the chip in it... And I do NOT have that right now.
