I was parking my Acura TL today and when I pulled out my key from the ignition to get out, I noticed my doors had locked. When I opened my door, the alarm went off. And then I couldn't turn off the alarm. The only way I got the alarm to stop was to put the key in the door and unlock it manually. What did I do to trigger the alarm in the first place and why wouldn't my key buttons turn it off? Where can I find info on what to do if this happens again? Thanks!
