Car Alarms: 2004 Hyundai Elantra Alarm issues, 2004 hyundai elantra, car alarm installer

Question
I have a 2004 Elantra sedan that has 37k miles on it with no issues until a week or so ago when the alarm (factory) started going off randomly.  Sometimes I can disarm using the remote, sometimes I can relock it with a click of the remote, others I have to physically go to the car, start it, then re-arm.  Could this be a computer issue with the security system?

Answer
It's an after market system
likely installed at the dealer you bought it from
as this car did not come factory alarm equipped.

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. Repeat steps to put into user
mode.

Then take it to a car alarm installer for
inspection of the issues you discussed.

Let me know how it goes.
