Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle. OR, Take the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). This way you will find out which parts, if any, you need to fix it - perhaps fix it yourself. OR, I've found the most probable cause (don't misunderstand me.. it could be something else) but I've found the 'Hood Switch" to be the most common cause. Try this, open the hood and locate the hood switch (right side toward front grille). Depress the switch all the way down, press the lock button on the keyless remote twice (just like you were locking the car (be sure all doors and trunk are closed when you do this). If the 'Answer Back" chirp/beep is heard, there's your problem. If it doesn't, it's probably something else and too little time/space here to explain the whole Electronic Time/Alarm & Control System (ETACS).

HOW PROGRAM THE KEY LESS ENTRY FOR SONATA 2012

How to Program Keyless Entry Remotes in a Hyundai Sonata By Christian Killian, eHow Contributor
20Found This Helpful The keyless entry system in your Hyundai Sonata is part of the factory alarm system. If you have to replace a lost or damaged remote, reprogramming will be necessary. The remote is important because not only does it lock and unlock the doors, it also arms and disarms that factory alarm when you open or close your car doors. New remotes are available from any Hyundai dealer. While they will program it for you, you can do it yourself and save a programming fee.

Step 1: Locate the fuse panel under the dash on the driver's side of the car. Just below it is the control module for the factory alarm system. Open the cover on the alarm system control module and locate the memory switch inside.
(Kleophaus Livingston/Demand Media) Step 2: Verify that the switch is in the "Off" position; if it is not, switch it to the "Off" position. This is important for the system to understand what you want it to do when you move to the programming mode.

Step 3: Insert the key into the ignition of your Sonata and turn the key to the "On" position. Wait for 60 seconds, then move the memory switch inside the control module to "Set."
(Kleophaus Livingston/Demand Media) Step 4: Depress and hold the "Lock" button on your remote for one full minute. This allows the remote and the control module to communicate and sync. Release the "Lock" button and turn the memory switch in the control module back to the "Off" position.
(Kleophaus Livingston/Demand Media) Step 5: Turn the ignition switch to the "Off" position and test the remote by pressing the "Lock" or "Unlock" button, verifying that the doors do lock or unlock.

Disable factory alarm


You are not able to disarm the factory alarm on this vehicle. You will need to have it diagnosed. But the issues sounds to me like the key fob is bad and needs to be replaced

I need instructions to program keyless entry remote for 2002 Hundai Santa Fe


For a 1994 to 2006 Sonata, a 2001 to 2006 Elantra, a 2000 to 2006 XG350 or a 2001 to 2006 Santa Fe, you will need to access alarm system control module. On most of those vehicles it is located on the driver's side fascia panel. But on the Sonata, the facia panel is in the center.

  • 2 Once you have found this module, you will want to ensure that the memory switch is in the OFF position. Then turn the ignition on.
  • 3 Wait 5 seconds and set the memory switch to SET position and then press the remote transmitter lock button to send the code to the alarm system control module.
  • 4 If you would like to program a second remote transmitter then you will need to press second remote transmitter lock button.
  • 5 Next set the memory switch to off, then turn the ignition off. You can confirm your programming by locking and unlocking the vehicle with both of the remotes. good luck my friend

    My alarm keeps going off on my 2007 Sonata. Ive located the fuse box but cannot figure out which one disables the alarm or horn until I can have it looked at. As of now I disconnected the battery.


    TAKE THE KEY THAT UNLOCKS YOUR CAR DOORS PUT IT IN THE LOCK TURN IT BACK TO THE LEFT AND HOLD IT FOR ABOUT 10 SECONDS THIS METHOD USALLY DISARMS THE ALARM.

    2007 Sonata car alarm(security alarm) randomly goes off--it's happened when it's locked and unlocked and all times of the day. The Keyfob stopped working about 3 weeks ago and then randomly worked now and...


    over sensitive sensor in the car could set it off randomly... bonnet boot, door handles.. one of the motion sensor thingiis, if fitted. the beeper issue could be the position of the incoming sensor of the alarm it self.. if it is an imboliser as well then there is whole other range of issue.. turn it off or at least disconnect the siren.. or you could just pay some one way too money to fix the problem for ya... good luck

    Car alarm randomly goes off


    there is a hood switch located at front passenger side under hood. check to make sure the plunger at hood is pushing the switch completely down. sometimes there may be just enough clearance that a strong wind will set the alarm off.
