So my wife goes to start up our 2004 TL today and nothing will turn on. There aren't any lights or power of any sort, including the horn. I quickly get on the iPhone and one of the suggestions is to use the key to lock and then relock the doors, thereby resetting the alarm. I do so and voila, the car starts right up.

However, when she went to turn on the radio, it is asking for the code. This leads me to think that power was lost in the vehicle (or is this just due to the anti-theft system?). Also, the anti-theft system red light blinks while the car is running/moving, which I don't recall being the case before.

We also noticed the clock says 1:02, so we weren't sure if that meant someone tried to get in the vehicle at 1:02 am or what.
Has anybody had this issue before? If so, what is it, and what do I need to do to fix it?
