Long time lurker and carPC fan (I haven't built mine yet though...just graduated and getting the money together for it now)

I'm wondering if anybody can help me out with this...

This morning when I was walking outside and trying to start my car with remote ignition, it did nothing but sound the alarm when i tried. (The procedure is to hit the lock button 2x and then hit the remote ignition button.) When I hit the button to start it, the car just kept honking.

Anybody ever heard of this and can clue me in on what's happening?
