Disable stock alarm system.

I have a 2001 Elantra GLS and now the alarm likes to go off for no
apparent reason. I have litterally just been sitting outside and looked
at the car and then it starts going off. I figuring that there might be
a bad hood or door sensor that is triggering the alarm. I really dont
care about the Alarm system and would rather just disable it then spend
the 90 bucks just for the diag from the dealer then pay for a new
sensor and labor. I checked both the interior and hood fuse boxes and
didnt see any fuse lable that it was for the alarm. Does anyone know
how to disable the alarm and perferable keep the keyless entry to work.
But if I have to sacrifice the keyless entry, im willing to do that.

Thanks

 

The alarm is integral with the time and alarm control unit, so it cannot be
disabled. If you don't use the remote to lock the car, however, it won't
set. Try to get in the habit of locking the doors with the manual lock
button on the driver's door. Then the alarm won't able, and you can still
use the remote to unlock the doors.

 

Find where the button meets the hood when it is closed. Others have
found that the spacing can change over time and trigger the alarm.
Supposedly it is adjustable?


my $0.02

 

The switch isn't *technically* adjustable, but bending the attaching
bracket will sometimes do the trick.

 

After looking in the interior fuse box, I found what kinda looks like a
jumper. on one side is says "on" and the other side says "off." I
pulled it out and rotated it 180 degrees and pushed it back in and that
seems to of worked but the keyless entry and power locks no longer
works but the car still starts and everything seems to work. Is this
maybe the switch

 

Not sure what that thing was that you switched since it isn't marked in
the owners manual. Hyundaitech?


I went to the garage to see if I could describe the switch better for
you. On my US spec Elantra it is a small black plunger syle button.
It is located about halfway up the passenger side fender next to the
power steering resovoir. If the rubber piece on the hood that pushes
the button is missing or worn it won't activate the button.

I was able to set off the alarm by holding it down and locking the car
(lights blinked) then taking my finger off the button made it think the
hood was opened and set off the siren. If the button isn't pushed when
the car is locked the lights don't flash and alarm isn't activated.

 

You've just disabled some stuff controlled by your time and alarm control
unit as well as probably the clock, radio, room lamp, and the door open
warning chime. I'd be surprised if your rear window defogger or
intermittent wipers work.

 

Does this disable keyless entry it does disable clock and radio but my wife has the remote an I dont wont her in my car.

 

find the hood switch, that tell the car the hood is open. Located close to the power steering reservoir. it is a one wire switch. open the wire and install a ground to it. this will keep all alarm and anti theft system to be activated.

 

would this work for a 2010 hyudai sonata?

 

I have a 2013 Sonata and the alarm goes off every time I try to get into the car. I have disabled the hood switch with no change. I went through the disable alarm steps, no help. I removed the horn fuse so the horn does not continue to wake up my neighbors. And to make things worse I just bought a 2019 Sonata and it does the same thing, I wish I could take this car back to the dealer and get my money back.

 

Why don't you ask the dealer to fix it?

 

I will never return to this Dealer. I am trying to make contact with another Dealer but they do not return my calls. This was a real bad decision to purchase this car.

 

I am sorry you feel that way.
And it is mostly due to the way the dealer treats its customers

 

I have now pulled the fuse out of the 2019 Sonata. And the alarm still goes off with the lights blinking but no horn, I am sure my neighbors are happy.

 

Bring it back to dealer.
Mention lemon law.
Have them fix it under warranty.

 

This car will never see that dealership again
