Car Alarms: 2007 Hyundai alarm = randomly goes off, valet mode, hyundai sonata

Question
I have two month old Hyundai Sonata (platinum edition).
The alarm goes off randomly, when just sitting unlocked in my garage. For example, two weeks no alarm going off unexpectedly, then in past four days 9 different random alarms.
Any ideas????

Answer
Well, if no manual exsists,
it's likely to be an after market system
from your description.

Also probably dealership installed when
it was purchased originaly.

The shock/impact sensor seems the culprit here.
It's likely to be found under the dash area, blinking
when anything taps on the underpanel.
Locate and either unplug or turn down.
To simply disarm it, locate and use the
valet/overide switch.

To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no alarm at all.

Let me know how it goes.
