Was the perimeter alarm an option on the '05? I was told my '05 has it but now that I think about it, I have never noticed the "THEFT" light blinking like it does in the '06. I'll have to have my wife dig out the window sticker later because this will annoy me all day. So, if I don't have the perimeter alarm and the '05 doesn't have a key chip, exactly what anti-theft system is left? The door locks?

I'm confused.....
