I have read other threads about the tumbler going out. This might be the case in my situation, but I am curious about why the car does not see that I have inserted the key, I have a blade key. I have the door open, the key in, and no chime/alarm telling me to take the key. Is this normal when the tumbler goes out or is this another issue. I have ordered another key, and I am having the same issue. I can get it to turn just a bit clockwisie..it makes a click. not sure if this is postion one. one note to add: I installed a aftermarket radio 2 weeks ago. Could this some how triggered some anti-theft feature that would lock the ignition down? Just trying to cover all bases. Thanks.
