This car alarm technology is really helpful to us especially this times that car thieves are so courageous. We have this neighbor couple houses away from us, he have new truck 2008 Tacoma, and the ALARM was so sensitive, there is no day that it won't alarm, sometimes it alarms many times in a day.
His truck is just couple months older that ours, same model and same color, dang!. The sales person explain to us that they will install the alarm and adjust it just right not too sensitive that when an accelerating car pass by it won't alarm. And yes it only alarm when you try to break in with force.
I wish they will adjust their car alarm cause its irritating sometimes hehehe
