I just got an 05 EX 2WD AT and I've noticed that when I arm the alarm, a blue light flashes underneath the dash, mounted on the removable panel below the steering wheel. There seems to be a button on the back but when I pushed it it didn't seem to do anything. Its also frustrating that if I'm sitting in the car with and lock the doors I must again unlock it with the remote before starting it, or else it wont start. Is this a factory alarm system or something aftermarket? Several of my friends have Es but I havent noticed the light on theirs. Thanks!
