I was told by my sales guy that it comes with a more sophisticated, full featured, manufacturer installed alarm with shock sensor and a couple other things. When I bought my 2010 in October it was 10pm when I did the paper work. The finance guy asked if i wanted the alarm and I declined. He handed me a little chip and told me to give it to my sales guy when I go back down stairs. I thought about "forgetting" about it but that would not be honest so when my sales guy asked for It I gave it to him. I watched him disable the alarm. He had a "master" transmitter and pushed a button on that then installed the chip into a module that is in plain sight under the steering wheel. It is a black card slot secured with two screws. Look for that.
