hi im new to this site and would appreciate some help. upon setting my alarm on my is200se by pressing the key fob once, the alarm triggers within 1 minute. however if i set it by pressing the fob twice thus disabling the interor sensors it is fine. on previus cars ive had its been possible to adjust the sensitivity of the sensor. is this possible on my car. ive only had the car a week and the previos owner gave me some bull that you had to press it twice to double lock it.
