For the system to activate, you must lock the doors and the liftgate from outside the vehicle with the remote key or smart key or by pressing the button on the outside of the door handle with the smart key in your possession.
All Hyundai vehicles produced since November 2021 are equipped with an engine immobilizer as standard equipment. Hyundai is also providing free steering wheel locks to law enforcement agencies for distribution to local residents who own or lease affected models.
Passive anti-theft systems

Passive anti-theft devices include: An alarm system that activates automatically when you turn the ignition off or shut your car door. Automatic disabling devices such as a computer chip in the ignition key. This device will prevent the car from starting if an unrecognized key is used.

If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key or keyless entry signal, or there may be a fault in the anti-theft module, keyless entry system or wiring.
The vehicle must be armed electronically to enable the alarm system) Vehicle theft: This alert occurs when tampering is detected with the vehicle`s key cylinder. This can be triggered by an invalid key, screwdriver, foreign key fob or no key detected when trying to start the vehicle.
The software upgrades certain Hyundai vehicles equipped with standard “turn-key-to-start” ignitions so they cannot be started without their keys when subjected to the popularized theft method.
Affected vehicles include 2017-2020 Hyundai Elantras, 2015-2019 Hyundai Sonatas, and 2020-2021 Hyundai Venues.
Infrared (IR) Security Sensors

Infrared sensors utilize infrared light to detect motion. In a security system, that motion triggers an alarm, turns on lights, or sends an alert. There are, however, two different types of infrared sensors commonly used in security devices ― active and passive infrared sensors.

Check The Fob And Owner`s Manual

If you have bought your car used, there`s a pretty easy way to check if your vehicle came with a car alarm installed: check the owner`s manual and look at the key-fob. Your vehicle`s manual is a great resource for finding out if the car came with an alarm.

The Anti-theft Light in the dash of your car should flash periodically to show that the system is engaged and active. You have to lock the doors of the car (without it running) for the alarm to engage.
The sensitivity of a car alarm is usually set on the shock sensor, which is going to be a small box that`s about three square inches underneath the dashboard on the driver`s side. Fortunately, there`s a simple way to find out if your sensors are set too high.
A passive alarm turns on automatically. Once the key is removed from the ignition and all the doors to the vehicle are closed, the alarm turns itself on. This function gives the alarm the name “passive,” as the driver does nothing to arm it. An active alarm must be activated by the driver.
Check the battery.

The first thing you should take a look into when the anti theft system car wont start is the car battery. It could be dead or low and needs charging. In that case, the car`s system won`t be able to read the security code off the key fob. Check the battery connections.

The anti-theft system may lock the wheel and prevent the key from turning in its slot. It occurs most often when you turn off the car and attempt to move the steering wheel. The next time you turn the key in the ignition, the car will start with the wheel fixed in that position.
Theft Alerts is a premium feature with AT&T Mobile Security Plus. It provides you with the information needed to recover your Android device if it`s stolen.
If your Hyundai vehicle has a push-button start or was produced after November 2021, it has an engine immobilizer and will not be affected. If your vehicle has a standard “turn-key-to-start” ignition system, please click here to input your VIN and see if your vehicle is eligible for the software upgrade.
If you own a 2011-2021 Kia or Hyundai, your vehicle may be at risk of being stolen. Any Hyundai or Kia vehicle that operates with a metal or steel key is impacted by a system flaw that thieves are targeting. Any Hyundai or Kia vehicle that is a push-to-start, is not at risk.
The anti-theft alarm activates when you attempt to open a door, hood, or trunk (tailgate) without using the smart key or remote control key after locking the doors with the smart key or remote control key. You can use the anti-theft alarm service only when the vehicle`s anti-theft alarm system is activated.
The software upgrade attempts to make these vehicles more resilient to theft by modifying their vehicle control modules to not only activate the factory alarm when locking the doors, but also a special “ignition kill” feature that prevents thieves from starting the vehicle.

the most relevant questions and answers related to your specific issue

Service ABS System, Traction Control System and Service Stability System
ANSWER : Hello. These systems are interconnected, since both of them can control individual wheel brake functions when operating. It is likely that one of the speed sensors are failing. To have this verified, have a qualified professional, like one from YourMechanic, diagnose the warning lights, pinpoint the fault(s), and make necessary repairs.

Disable or bypass factory security system
ANSWER : To temporarily override the system, see these instructions. A permanent bypass requires re-engineering the system because engine immobilizers these days rely on multiple electronic modules and chips, the very removal or modification of any one of which, or reconfiguration, will itself activate the immobilizer. These immobilizer systems are complex and nearly foolproof to all but highly trained electrical engineers and even they will have trouble due to the need for specialized components, programming and so forth. That’s why these systems have been so effective of late in preventing car thefts. Immobilizers are essentially undefeatable unless you want to spend many, many hours poring over circuit schematics to design a unique bypass strategy. The bottom line is, in your circumstances it will be vastly easier, more efficient, and less costly to simply fix the immobilizer system that you already have in place. Indeed, the Factory Service Manual has a diagnostic protocol to accomplish just that. To that end, if you request a system electrical diagnostic a certified Mechanic, dispatched by YourMechanic right to your location, will get this resolved for you.

check break system and indicators of side brake, doors open,and traction system and full light warning in dash board
ANSWER : Hi there, thanks for writing in.

It sounds like you are having a serious electrical malfunction, which is very hard to diagnose without being able to look at the car first hand. The first step to diagnosing your electrical issue would be to scan all the relevant control modules in the vehicle, to see if there are any faults relating to any of these issues. It sounds like somebody at the dealer has been trying to fix this problem, so it may be a more involved one. I have personally seen failed control modules cause things like this, but that is no guarantee that it’s the problem in your case. It would be best to have a qualified independent technician, such as one from YourMechanic, look at your car to diagnose your electrical problem.

Intermittent random faults showing up on dash and I drive system. One at a time. Mainly transmission error and lighting system err
ANSWER : Hello. When it comes to power issues while driving, it is typically related to the charging system in some way. A miscommunication with the battery would effect the performance. Before getting too technical, start with the simple stuff. Check the alternator output with a voltmeter, or have it tested at your local automotive store. If both the battery and the alternator are in good working condition, then you can turn your attention to a control module or a programming issue. The warning codes that are being triggered should be read and used to help in the diagnosis. If several different systems are failing, you will likely have a charging system error, or a malfunctioning control module. Further testing is needed.

can i get pitman arm and idler arm fixed?
ANSWER : Hi there. The Pitman Arm & Idler Arm are essentially the same component; however, they operate on opposite sides of the vehicle. The idler arm operates on the passenger side, while the pitman arm connects the steering box to the drag link. Although our mobile mechanics can possibly complete these repairs, the most important part of the repair, having the suspension professionally aligned is something we are not capable of completing. As such, this is a service that would be better served to be completed by a professional suspension repair facility.

Bolt on 06 Elantra control arm no longer attached
ANSWER : The repair will depend on whether the arm detached and as a consequence got damaged. Also, detachment of the arm if the vehicle is moving can potentially damage other parts such as the mounting boss(es) on the frame that the arm is bolted to. The best case would be if the arm got loose at low speed, nothing got twisted or broken and it can all just be bolted back together and the wheel alignment checked. Worst case is the control arm could have sustained damage, and will have to be replaced and, as noted, all accompanying and adjacent parts will have to be inspected to be everything is safe and secure. Your best bet is to just request an inspection of the control arm. A certified mechanic will come right to your location and take all necessary steps to get this resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

How do I use the audio system with a navigation system?
ANSWER : If you have an Accord with an in-dash navigation system, there’s good news. Most of your audio system functionality still comes from the standard buttons on the interface. However, there are some things you can only do by using the “interface dial”. This is the large knob on the lower center portion of your system. It combines three different elements:

The enter button
The rotating knob
The selector direction pad (up, down, left and right)

The selector pad is what lets you access the menu system, and scroll through lists, menus and other items.

To access a menu item, use the arrows or knob to highlight it, and then press enter.
