the stock alarm isnt that bad... i just hate the fact that instead of having a nice "beep" when you lock/unlock, its just the damn horn
my alarm goes off every few days in the middle of the night because of my neighbors cats...i should call animal control...
Mine has the nice beep. Only time my horn sounds is when the alarm goes off.
As for switching the sensitivity up, the only thing I wouldn't like is when there is a loud noise, the alarm goes off. I would rather it make a few warning beeps or something, instead of it just wailing.
One more thing. This has happened a few times to me, and I don't know if it's just me, but sometimes when I go to lock/unlock my car, I will hear one or two beeps, and then the next beeps that follow will be of a higher pitch and a completely different tone.
For example, if I hit my unlock button twice to open the trunk or passenger side door, I'll hear beep, beeeep, beep, beeeep. Or beep, beep, beeeeep, beeeeep.
Sorry, I don't know how else to type out what it sounds like, so lay off.
