as jager has said, if your car chirps, then something is
not secure. 99% of the time the culprit is the center console lid is not completely closed.
pressing (or locking) twice will disarm the IR sensors. and the car will chirp letting you know you disabled the sensors.
two chirps indicate something is wrong with the system itself.
the turn signal indicators should flash twice and the red lights on the dash (above the radio and on the top of the dash) flash quickly for 10 seconds, then flash once per second if the IR is
enabled.
if the IR is
disabled, the alarm will chirp once and the lights on the dash will be solid for 10 seconds, then flash once per second.
