“Kia Boyz” (10-21 Kia & 16-21 Hyundai) Theft Prevention

In recent years, the so-called “Kia Boys” trend has taken off on social media and led to a huge increase in thefts of certain Kia and Hyundai models. These thieves—usually teenagers—have been able to steal specific vehicles with nothing more than a USB cable because many 2011–2021 models were built without engine immobilizers. They often commit these thefts simply for enjoyment and posting on social media, usually resulting in severe damage or destruction of the vehicle. This issue only affects models that use a traditional metal key; push-button start vehicles aren’t vulnerable to this method. The most commonly targeted vehicles include the Kia Forte, Soul, Rio, and Sportage, along with the Hyundai Elantra, Sonata, Tucson, and Accent, just to name a few. Due to this issue it is becoming harder and more costly to insure an affected vehicle, with some companies adding stipulations that you use certain preventative measures. In this article, we’ll cover what steps you can take to protect your vehicle from becoming their next target. Be sure to read our full article on Layered Defense for Auto Theft Prevention but here are some steps to take for your Kia/Hyundai:

Our Recommended Layered Defense Setups

Choose the setup that’s best for you, your budget and your vehicle. There are many great products not listed in these examples that you may decide to use (see other products below). Just make sure to choose products you won’t mind using consistently.

What is important to include when building the layered defense for your Kia or Hyundai is:

1. An immobilizer that will help prevent it from starting. For example IGLA, Ravelco, Immobilizers built into alarm systems, etc. Most immobilizers can be used together to further reduce the small chance they will be overridden.
2. Visible deterrent like a club
3. (Preferably) a 2-way alarm system to notify you of theft attempts in real-time

Kia Software Update

Kia and Hyundai have developed a software update to help combat the theft trend, however it is far from perfect. The update can be obtained from your dealership for free and essentially acts as an immobilizer, but only when armed from your key fob, and after a short delay. Some thieves have been able to override the update, and it doesn’t work if you do not arm it correctly, i.e.; locking your car with the button on your door instead of the key fob. But it is better than nothing and it is free. I would highly recommend using other security measure in addition to this for these highly targeted vehicles. The update is available for most but not all of the affected cars, so contact your local dealership to see if your vehicle is eligible.

JDI Ghost Key Push-To-Start Conversion

The JDI Ghost Key push-to-start conversion is an aftermarket security upgrade designed to help protect vulnerable Kia and Hyundai vehicles—particularly those targeted by the “Kia Boys” theft trend due to lacking factory immobilizers. This kit replaces the traditional mechanical ignition with a push-button start system that includes an integrated transponder-based immobilizer, making it much harder to start the car without the proper RFID chip. By adding a layer of electronic authentication, it prevents the common theft method of using a USB or screwdriver to crank the ignition, as it replaces the traditional key ignition system. While highly effective, the installation must be done correctly by a professional to ensure proper function, and it’s still best used in combination with other anti-theft measures like a steering wheel lock or GPS tracker, etc. for maximum protection.

Aftermarket Alarm Systems

Adding an alarm system to your Kia or Hyundai can be a worthwhile investment for preventing theft. But you need to get a quality system, and have it installed by professionals. A regular car alarm that just makes your horn go off will likely not do a great job of deterring thieves, most people, especially in larger cities, ignore car alarms going off as it is such a regular occurrence. It might scare off some, but most criminals aren’t too afraid of it, and many know how to avoid setting off factory alarm systems in certain vehicles. Luckily, nicer aftermarket alarm systems can do much more than cause a bit of noise, and can be harder for thieves to avoid setting off. Many alarm systems have features like:

• Starter Immobilizers that prevent car from being started if alarm is armed- even with the key.
• 2-way notifications that alert you via your key fob or phone when your alarm is going off.
• Shock sensors that set off alarm when vehicle is hit
• Audio glass break sensors that listen for your glass being broken
• Tilt Sensors that can detect if your vehicle is being towed or jacked up to steal wheels.
• Built in GPS
• Blinking light for deterrence

Immobilizing Devices

There are many types of devices designed to prevent unauthorized people from starting your car. Choosing the right one is an important part of your anti-theft plan, especially on the Kia and Hyundai models that lack the security keys found on most modern vehicles. Here are some different options of immobilizing devices that can be installed in your vehicle:

• IGLA Anti-Theft System– The IGLA Anti-Theft System is an immobilizing anti-theft system that is available for many Hyundai/Kia models and prevents the car from starting unless the driver enters a custom PIN sequence using the vehicle’s existing buttons, such as steering wheel or door controls. Because the IGLA integrates directly with the vehicle’s electronic network, it offers strong protection against the theft methods commonly used on Infiniti models, including relay attacks, key cloning, and CAN-Bus hacking. There are no extra key fobs, modules, or visible components for a thief to spot, making it extremely hard to identify or bypass. It also includes a service mode, allowing you to leave the car for maintenance without exposing it to risk. While it will likely cost somewhere in the $1,000 range, it is a very effective system for helping you keep your car. (Read more about IGLA here.)
• Ravelco– The Ravelco is one of the strongest options available for preventing your Kia or Hyundai from being started, but it’s also one of the more expensive choices, usually running between $800 and $1,000. The system uses a unique removable plug—usually mounted discreetly under the dash—that’s wired deep into your vehicle’s harness to interrupt a critical part of the starting circuit. When the plug is removed, the car simply cannot start. Just keep in mind that the Ravelco only works if you actually remove the plug and take it with you every time you leave the vehicle. (Read more about Ravelco here.)
• Certain types of aftermarket alarm systems– In addition to all the other features, most good alarm systems have a starter interrupt that will activate when the system is armed. These will greatly vary in cost depending on what you pick out, but will typically run you from around $500 to over $1,000 installed. Alarm systems are typically not quite as difficult for a thief to defeat as a Ravelco system, but they are easier to use all the time, as all you have to do is press the lock button on your alarm’s remote. Not to mention you’re getting much more than an immobilizer. You may be able to use both an alarm system and the Ravelco together if you choose, however the alarm immobilizer is more than likely enough to thwart a Kia Boy looking for an easy target (Read more on alarm systems here.)
• Cyclops TAM– The Cyclops TAM (Theft Avoidance Module) device is an aftermarket anti-theft solution that replaces a relay required to start your vehicle, and is controlled by a remote, allowing you to disable your vehicle from being started without modifying the wiring of your vehicle. While it is not quite as difficult to defeat as devices that are deeply integrated into the wiring, it is cheaper, easier to install, tracking it down would still take some time and effort, and “Kia Boys” aren’t exactly sophisticated car thieves. (See more here)
• Kill switches– (View on Amazon) Kill switches are a less effective immobilizer, but they’re still better than nothing—especially if you’re trying to protect a vulnerable Kia or Hyundai without spending a lot of money. A kill switch works by wiring a hidden toggle switch, button, or even a magnetic switch into your vehicle’s starting circuit so the car won’t crank when the switch is off. The downside is that, unlike something like a Ravelco or an advanced digital immobilizer, there’s no unique plug or encrypted remote involved. If a thief manages to locate your switch, it won’t do you any good. If you choose this route, take the time to hide the switch extremely well and consider adding a semi-hidden decoy switch under the dash to throw thieves off. Most mechanics—or experienced DIYers—can install one of these. (Read more about kill switches here.)
• Remote Battery Disconnect Switches– (View on Amazon) Remote battery disconnect switches are another low-cost option, though they come with their share of drawbacks. These units are simple enough for most people to install on their own—if you can replace your car battery, you can install one. They typically cost around $30 on Amazon and work by mounting between your negative battery post and cable, allowing you to “cut” battery power with a button on the included remote. However, there are two main downsides. First, shutting off battery power also disables your alarm system if you have one. Second, if a thief pops your hood, a determined one can defeat the device fairly easily. Still, for budget-minded owners—especially those driving Kia and Hyundai models frequently targeted in Kia Boyz-style thefts, this can be a helpful layer. Many thieves won’t bother diagnosing why a car has no power. (Read more on remote battery disconnect here.)

“The Club” and Similar Devices

Steering wheel locks (A.K.A “The Club”) are a very well-known and cost-effective theft deterrent. While they can be easily defeated by a determined thief who is properly equipped, a bright colored club on the steering wheel will often deter thieves and cause them to move on to an easier target. They are a fairly inexpensive layer of security to add to your Kia or Hyundai so it is well worth it to avoid the headache of falling victim to the “Kia Boyz”.   (Read more about clubs here.)

Brake/Clutch Pedal Locks

Brake and clutch pedal locks come in several designs, but they all function by preventing the pedal from being pressed down—something that, depending on your vehicle, can keep it from being shifted or even started. This adds another obstacle a thief must deal with, though pedal locks aren’t as strong of a visual deterrent as a steering wheel lock and tend to be a bit more inconvenient for daily use, since you typically have to stand outside the car to install them. It is possible to get a steering wheel lock and pedal lock combo with the same keys so you can use both simultaneously. (Read more about pedal locks here.)

“Boots”/Wheel Locks

You’ve probably seen vehicles fitted with wheel boots for parking violations, but similar devices are available for personal theft prevention. While they’re bulky and less convenient than most anti-theft devices, they’re a strong visual deterrent that adds significant time and difficulty for anyone trying to steal a Kia or Hyundai. They’re especially useful if your vehicle will be parked for an extended period, such as during a vacation. As with any security device, though, it only works if you actually use it. (See more on wheel locks here)

Gear Shifter Lock

Similar to a steering wheel club, a gear shifter lock is a strong visual deterrent that adds meaningful time to any theft attempt. It prevents your shifter from moving, making it impossible for a thief to take the vehicle out of park when the lock is properly installed. Most thieves won’t want to waste time cutting through it, and even if they try, the extra time and noise increases the odds they’ll be caught in the act. *Make sure to verify fitment for your particular model* (See more about gear shifter locks here.)

Removing a Fuse or Relay

One way to prevent your car from being started- that costs nothing- is to remove a fuse or relay that is required for the vehicle to start and put in your pocket or other secure location away from the vehicle. Thieves are unlikely to take the time to diagnose the reason your car won’t start and will likely move on to another vehicle. If you’re somewhat mechanically inclined you can just use your owner’s manual to determine which fuse to remove, or just consult your mechanic. Make sure you don’t remove a fuse necessary for other security features such as an alarm system, and be careful not to remove one that could damage your vehicle if a start up attempt is made without the fuse. Also be sure not to lose the fuse or you’ll be in for a bad time, especially if you aren’t at home. Using an immobilizing device is much easier than this method, but this can be a good additional measure if you’re vehicle is going to be left unattended for a long time, or if you’re just on a tight budget.

Tracking Devices

You hope you never need a tracking device, but if your car is ever stolen, you’ll be glad you invested in one. Having a live location to give police dramatically increases the chances of getting your vehicle back quickly and in better condition. Trackers also offer day-to-day peace of mind, letting you check your vehicle’s location anytime or even find it when you forget where you parked. There are a lot of tracker options on the market: some hard-wired into the vehicle, others battery-powered with surprisingly long battery life, using different technologies such as GPS, cellular networks, or Bluetooth. Each type has its strengths and weaknesses, so using more than one type, hidden well in different locations will provide optimal tracking even if your car gets taken by a smarter-than-average Kia Boy. (Read our full article about tracking devices here)

Shatter-resistant Film for Windows

Many tint shops can install a security film on your windows that can make them much harder to get through when broken. Compare it to how the laminated glass of a windshield stays together after an impact for your safety. If you locked your car like you should, chances are the “Kia Boys” will smash your window to gain entry to your vehicle, they will usually go for the rear windows because they are made of tempered glass which breaks into a thousand pieces. Using a security film can make their job harder and potentially make them give up out of frustration. Definitely don’t use this as your only security measure, as preventing the car from starting and deterrents like the club are going to be more effective, but it can be a helpful addition to a good security plan. Keep in mind that adding security film to your car windows could create a safety hazard should you be in an emergency where you need to escape your car by breaking the window, so it’s always important to weigh the risks. (Read more about window film here.)

Security Screws to Delay License Plate Removal

Once your core anti-theft measures are in place, license plate security screws are an inexpensive way to add another layer of protection. They require a specialized bit to remove, making your Kia or Hyundai’s plate much more difficult to steal. If the vehicle is stolen, thieves are more likely to leave it with its original plate still attached, increasing the chances that police can identify it as stolen. Just remember, these won’t do anything to prevent theft of the actual car, they are more of a bonus step to potentially help recovery and be a hassle/waste of time for the thieves. (See more on security license plate screws here.)

Security Measures When Parked at Home

• If you have a garage, use it– Parking your Kia or Hyundai in a garage whenever possible is one of the easiest ways to reduce the risk of theft. It keeps the vehicle out of sight, and adds another barrier for thieves to overcome.
• Use home security cameras and lighting– (View on Amazon) Put extra pressure on thieves by having your driveway well lit with motion sensing floodlights and cameras pointed at your car and elsewhere on your property. Many thieves will not be deterred by this, but it is still a worthwhile step that makes your house just a little bit less desirable of a target, and the cameras will provide good evidence if anything happens. (Read more about security cameras here)
• Block in your Kia/Hyundai with lower risk cars– If you have a second vehicle that’s at lower risk of theft, consider parking it behind your Kia or Hyundai to make it more difficult for thieves to access.
• Install a driveway motion sensor– (View on Amazon) A driveway sensor can alert you as soon as someone enters your property at night, giving you a chance to respond while a theft attempt is still in progress instead of discovering it the next morning. (Read more on driveway motion detectors here)
• Consider installing a gate– It’s not cheap, but a gate will increase security for not only your vehicle, but your entire property.
