Car Alarms: cobra alarm, cobra alarm, inset

Question
hi my cobra alarm keeps going off on its own just radome

Answer
Falsing is usually attributed to a sensor set too high
or, damaged door pin switches. Let's assume the door pins are
fine. That leaves the Cobra after market sensor.

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.

Hint, if all thing being equal, your door
triggers protect the vehicle well now,
try unplugging the shock for now to test.

Good luck.
