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.

You are most likely correct, it probably has an alarm. Unfortunately, most alarm systems are connected to the remote that is broken. You should have to have your dealership get you a new remote for the vehicle.

Their Commando FM 870 has a remote transmitter pager and remote starter, allowing you to control your car from almost a half mile away. It instantly alerts you if your car is being tampered with ($169). CommandoAlarms.com is their website.------------------------------------------------------------------------------------

Your Sonata is equipped with a "Keyless Entry & Burglar Alarm" system. When the Burglar Alarm is activated, it KILLS the starting system through the used of a relay called the "Burglar Alarm Relay". This mode prevents engine starting with the key.
Solution #1
Disarm the system with the Keyless Remote (key fob) If you don't have this remote (or its battery is dead) replace the battery & try disarming again.
Solution #2
Enter the vehicle & insert the key in the ignition and turn the ignition switch to 'RUN'. Wait 3 to 5 minutes until the alarm stops. You should then be able to start the engine.

Have a qualified/certified Hyundai Service Technician properly diagnose this issue.

The 2003 Sonata is equipped with a 'starter KILL' burglar alarm system with disables the starting system (using a N/C 'contacts' configuration instead of a N/O contacts configuration). N/C=Normally closed, and N/O=Normally open contacts. When the alarm goes off with a MY Sonata, the only way to DISARM it is with the key fob (remote) originally programmed for it (unless you purchase a new remote & have it programmed for the vehicle at an authorized Hyundai Service Department). NOTE: So long as the keyless entry & burglar alarm system is functioning/operating normally, the alarm will keep going off and the STARTER KILL function will still prevent you from starting the vehicle. One option is left without purchasing a new remote and having it programmed.
1. When the alarm goes off, get into the vehicle and insert the ignition key into the ignition.
2. Turn the key to the 'RUN' position (NOT the ACC position) and wait for the alarm to STOP (usually about 3 to 5 minutes).
3. The engine should then start using the ignition key.

If this procedure doesn't work, the problem will need further diagnosis by a qualified/certified Hyundai Service Technician.

Hope this helps

my 2003 just stopped running as i made a left turn everything works on it lights alarm ect it just wont start now it trys but wonk and one can help please and thank you

assuming you say that the engine turns over but wont start,1st make sure you have good batteries in the remote then sit in car with key in ignition turned on,press/hold the alarm button on the remote,get back to me if this doesnt work (with both remotes).

Sounds like you have a shorted wire causing a drain. I recommend disconnecting the alarm all together which should stop the short so battery can remain fully charged.

When the alarm is activated, there is an Anti-Theft device (Starter Kill Relay) which prevents anyone from starting the engine using the key (about 5 minutes). If you place the key in the ignition and turn the key to the "RUN" position, wait 5 minutes (approx), the engine should then be able to start. If not, the problem may be the ETACS (Electronic Time & Alarm Control System) module. If it does start, the problem may simply be that the battery in the keyless remote is weak/dead, or the remote needs to be programmed again for that vehicle. Only the remote can 'DEACTIVATE' the alarm. Best solution, take/tow 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.).

One word:

Dealer.

Next time just disconnect the battery until you get it towed as this is a warranty item. I'll bet some wondered if this was a prank question like I did, right?
