My Sonata’s security system has been gradually driving me crazy, and now it has prevented me from operating the vehicle. I may have used up the battery more quickly than I realized because when I tried to start the engine after listening to the radio with my kid, the car alarm went off and wouldn’t let me. (I think it was a stupid design choice to disable the starter and activate the car alarm if the battery voltage was too low.) My greatest efforts have not been successful in getting the car to try to start or turn over. What actions should I take in relation to this now? If I can avoid it, I don’t want to have to tow the car to a repair who specializes in electrical problems.
My key fob does not have any known remote start capabilities, and this is not a keyless start.
Despite activating the alarm, the key and the fob both open and close the doors and trunk.
The immobilizer/security system’s indication bulbs are completely absent from the instrument cluster, but there is an LED attached to the wire harness just behind and slightly above the brake pedal.
A button that was once connected to the system and appeared to function as a reset or bypass switch now appears to have no effect.
Two separate cables with male spade terminal connectors are located behind the steering wheel. One is solid green, while the other is solid yellow.
Despite the security system immobilizing the ignition, every mechanic we spoke to claims that the model I own does not come with an immobilizer.
The car alarm would occasionally go off when the key was in the door, with a 1:15 probability, up until the point where the car wouldn’t start.
I’ve included an image of the dash module that I believe is at least connected to the problem.
Method 2: Start the engine.
You won’t be able to start the car if the anti-theft system has locked up the engine. Use the next few procedures to turn off the system and start your automobile.
First, examine the anti-theft light. Most contemporary vehicles have a dash light that flashes when the anti-theft system is activated. The anti-theft system’s icon resembles both an automobile and a lock combination. The anti-theft system in your automobile is engaged when this light is on and flashing (it will either be blue or red).
Step 2: Start the engine. Just turn on the accessories with your automobile key in the ignition; the engine will not start.
Step 3: Perform an additional inspection of the anti-theft light. Turn the key to the “off” position and wait a few minutes before starting your car again if it has stopped blinking. Otherwise, your car won’t start. This enables the system to completely reset itself.
Repeat this method in step 5. See if repeating these actions will solve the problem.
How do I unlock the anti-theft mode on my Hyundai Sonata?
Put the key into the door lock as the first step. Even if the car has a keyless entry system, use the side door on the driver’s side and the actual key. Step 2: Rotate the car key to open the door without opening it. Hold the key in place for 30 seconds.

2. If that doesn’t work, try unplugging the battery’s ground lead for five minutes. This should reset the immobilizer module.
3. To disable the immobilizer, you can enter the limp home password on the metal tag that comes with the keys by using the ignition key. See manual illustration.
How can the anti-theft mechanism be defeated?
Step 1 is to place your key into the door’s lock. Even if your car has a keyless entry system, use the driver’s side door and the traditional key.
Turn the key in step two. Don’t let the key go after turning it to unlock your automobile door.
For 20 to 30 seconds, maintain this position for the key. By doing so, you can disable the alarm system and let the system know you have the right key. Some automobiles may recognize the key by just rotating it in the door lock key cylinder back and forth.
To disable the anti-theft feature, try fully turning the key both ways.
While you may be grateful for an anti-theft system that prevents your automobile from operating normally in the event of a crime, it is currently causing you a great deal of inconvenience, which these procedures have hopefully helped you eliminate. You should speak with a specialist from YourMechanic if your car still won’t start to find out whether there is another problem preventing it from starting.
What is the turnaround time for the anti-theft system?
It doesn’t always take that long, but leave the key there for 15 minutes just in case. Once that period has passed, see if the anti-theft light, if one was lighted, is still on. Wait three more minutes after reversing the key two positions to the Lock position.
What causes the car’s anti-theft system to activate?
Sensors that are mounted in and around the car are used by the anti-theft alarm system to function. The sensors are activated by an impact or motions inside the vehicle. In turn, it sets off the alarm, which then sounds. The alarm finally sounds, alerting the owner or individuals. Even a slight shift in the posture of the car can cause the tilt sensor to alert and trigger the anti-theft alarm system.
Additionally, you can either install an aftermarket alarm or purchase a car from the manufacturer (OEM) with factory-installed alarms. The Remote Keyless Entry System, which aids in locking and unlocking doors and even starting engines, is typically included in OEM systems. Additionally, radio receivers, immobilizers, motion detectors, and wireless USB systems are all used in Remote Keyless Alarm systems. The Remote Keyless System uses strong cryptography authentication procedures as well.
How can I reset my car alarm now that the battery has been changed?
Making sure the battery is correctly linked and that your car’s hood is securely closed is the first thing you should do if you want to confirm that your car alarm is operating as intended following a battery swap. You might wish to wait for around 10 minutes to make sure your battery is fully charged and once more supplying power.
You can lock and unlock the car using your key fob once your battery is completely functional. Then, before attempting to start your automobile, you should insert your vehicle’s key and hold it in the “on” position for 10 seconds. Check the dashboard system of your automobile to see if the warning light for the car alarm goes out or remains on. When the car is started, if the light goes out as usual, the system should have been reset correctly and without any problems.
After changing the battery in your automobile, you usually won’t need to do anything; the alarm should reset itself. You might need to press a reset button on the alarm box, which might be positioned next to the steering wheel, in some cars or alarm systems. Others could need a particular set of instructions, which are detailed in your user manual, especially if your system was installed aftermarket.

Will removing the battery reset the anti-theft system?
Resetting the anti-theft system and the car’s computer system requires disconnecting the battery connections for 5 to 10 minutes. While this may assist in resolving the difficulties causing your anti-theft system to behave strangely, its effectiveness is not assured if there are additional problems.
