Car Alarms: False alarms on Securikey (on a 99 RAV4), false alarms, securikey

Question
The Securikey system on my '99 RAV4 emits occasonal false alarms. I haven't detected anything in particular that sets these off. I wonder if passing traffic causes the false alarms, but I haven't actually observed a cause and effect. Is there any way that I can reduce the sensitivity of the alarm system myself, without taking it to a mechanic? (The car is new to me.)

Thanks!

Answer
Not certain of the system, but MOST knock/impact
sensors have a wheel inset into it to turn up or down
(counter clockwise is down).

Locate the sensor under the dash and turn down or
simply unplug it. Should be a little oblong box
wire tied up high under the dash, and would
blink when it detects vibration.

Good luck.
