QuestionQUESTION: I bought a used 2007 Hyundai Elantra about a year and half ago. I had it about a year when intermittently the car alarm would go off. Just last week, I put it in the shop for some recall parts and told them about the problem. Sorry, to say, it never gave the problem while we were gone. The first day back to work, it went off while I was walking through the parking lot. The next day, as I was leaving, the security guard told me that it had sounded off and on all day. Of course, the dealership wants me to bring it back in but I don't have the funds for them to research what the problem is. They would not disclose over the phone how to disable it. Could you please help?
ANSWER: Please be more descriptive if possible.
"GOING OFF?"
I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.
Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
(doubtfull since none of the notes show this
car as having a factory alarm system)=FACTORY
Or,
is it: flashing parking lights,
an LED in the dash area, and a siren
going off?= AFTER MARKET
Let me know more on this to better
advise you on a course of action
to take.

QUESTION: It is a car horn and flashing headlights. I bought the car used but I'm fairly certain that it is a factory alarm. It doesn't sound like a siren.
AnswerOk, a bit complicated & problematic.
This system depends on the physical action
of the door lock locking and unlocking-arming and disarming.
If you have a factory remote, that would do this to
specifications. It is also designed to only disarm using
the OEM/FACTORY remote that came with it.
So, disarming this can only be achieved 3 ways:
1. Try this first, Use key in the drivers door, turn left,
then right to disarm and unlock. Most all Japanese OEM
alarms would disarm this way.
2. Add an after market keyless entry system to emulate
the factory remote functions. I have several models
if this option suits you. (However, it may not disarm
THIS particular model as it's designed to only
disarm using the RF signal from the original remote!)
3. Acquire or use & or, replace the original remote that
can control it as specified. This would be at the
local dealership parts department.
(This is why there is no wire you could ground
without affecting the door lock system.
A single negative pulse to the unlock wire will disarm
without unlocking, yes, but would always disable the
locking mechanism. Not good.)
Keep in mind, if this is after market
(siren and flashing parking lights)
then it's a different method entirely.
The standard method to disables as follows:
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 emitting diode) light in the dash
should also go on solid. If it's a toggle type,
then key on, flip the switch in the other direction
This would be OVERRIDE/VALET mode.
Repeat this process to toggle back to service mode.
Lastly this car has a transponder in the ignition key
and ignition column. if this system is in "TAMPER MODE"
and the fuel rail has shut down, there is nothing
you can do personally to disable it. The dealer will need
to put it into a diagnostic reset through they're
code reader writer system in the service dept.
Let me know what applies
to your issues.
