Many owners are worried about their precious Alphard or Vellfire being stolen. Unfortunately, these popular models, with their luxurious interiors and exteriors and high resale value, are prime targets for thieves. With theft methods becoming more sophisticated every year, traditional measures alone are no longer enough to protect your beloved car. Tragic cases have sometimes occurred, with cars being stolen during just a few minutes’ break at a service area on the highway, and once stolen, it is extremely difficult to recover your beloved car.
We’ll provide detailed information on the latest 2025 information, from the latest tactics used by thieves to specific measures to ensure the protection of your Alphard or Vellfire. Be sure to read to the end to find out all the essential information you need to protect your beloved car.
The background behind the targeting of Alphard Vellfire and increasingly sophisticated theft methods
Toyota’s flagship luxury minivans, the Alphard and Vellfire, have captivated many with their luxury and comfort. However, due to their popularity and demand, they are in high demand not only in Japan but also overseas, and unfortunately, are known to be prone to theft. In particular, the 40 series, with its luxurious and well-equipped grades such as the “Executive Lounge,” is in high demand in the used car market and overseas, and tends to be a frequent target for theft.
According to announcements from the General Insurance Association of Japan and the National Police Agency’s Public Safety Planning Division, the number of thefts of the Toyota Land Cruiser remains the second highest in the first half of 2024, a trend that continues unabated. By 2024, the theft rate is expected to reach hundreds of vehicles, and it has been pointed out that even the latest 40-series Alphard is at risk of being unable to completely prevent such thefts. It is believed that many stolen Alphards are exported overseas, particularly to Asia, the Middle East, and Australia, and this overseas demand could be one of the reasons for the Alphard’s high theft rate.
Alphard/Vellfire are prone to theft
First of all, the Alphard/Vellfire is a car model that is very prone to theft.

The Alphard’s exterior features also increase the risk of theft. Its large size and eye-catching design make it easily identifiable in parking lots and on the road, creating an environment that makes it an easy target for criminals. In addition, its size makes it relatively easy to dismantle and modify after theft, and even smuggle it overseas, another reason why it is so susceptible to theft.
The latest theft methods and their mechanisms
Thieves are using the latest technology to steal vehicles in incredibly sophisticated ways, and in an increasing number of cases, original equipment security systems are no longer sufficient.
Relay Attack
A relay attack is a method of amplifying weak radio waves emitted from a smart key with a special device and relaying them to the car, making the car mistakenly believe that a legitimate key is nearby. This makes it easy to unlock the doors and start the engine. This is particularly true if the smart key is kept near the front door of your home, or if the parking lot faces the road, and is prone to attacks at night or in environments without security cameras.
To counter this tactic, you can store the smart key in a case or pouch that blocks radio waves, keep the key in a room away from the car, or, if the smart key has a function to temporarily turn off the radio waves, use this.
CAN Invaders
CAN Invaders target the “CAN bus,” a communication system that allows each electronic component in a vehicle to exchange information. Thieves use specialized equipment to send false instructions to this CAN bus, allowing them to open the doors and start the engine without a legitimate key. This method is unique in that it directly infiltrates the vehicle’s network, allowing the vehicle to be operated even without a physical key. Manufacturers are strengthening their countermeasures through software updates and other means, but it is difficult to completely eliminate the risk, and owners themselves must take additional security measures.
Game Boy (key emulator)
A key emulator, also known as a “Game Boy,” is a device that perfectly copies the signals of a genuine smart key and operates a vehicle as if it were the real key. This makes it easy to unlock the doors and start the engine. The tricky thing about this method is that it does not require real-time radio wave relay like a relay attack, and once the key information is emulated, the duplicated key can be used to operate the vehicle any number of times. Because key information that cannot be obtained through official channels such as dealerships is analyzed and duplicated using illegal tools, the risk of the vehicle being stolen without the owner’s knowledge increases dramatically.
The reality and limitations of the Alphard and Vellfire’s genuine security system
The Alphard and Vellfire are equipped with a variety of genuine security systems to prevent theft. Manufacturer-supplied anti-theft devices primarily consist of immobilizers and genuine alarms, which are linked to keyless entry or keyless entry button operations. Furthermore, for five years after initial registration, T-Connect provides a feature that allows you to check the status of your car via a smartphone app. However, these systems are currently being circumvented by thieves using clever tactics.
Limitations of genuine security systems
Since manufacturer-supplied security systems are common to many vehicles, they can serve as a template for thieves to exploit. They work day and night to research the latest security technologies, and if they succeed in breaking through a system once, they can apply that method to other vehicles, causing large-scale thefts.
- Smart Key System : The Alphard is equipped with the latest smart key system, which allows you to unlock the vehicle and start the engine simply by carrying the key. The smart key contains a unique encryption code that prevents the key from being duplicated or used fraudulently, but it is vulnerable to relay attacks and other methods that exploit radio waves, such as those used by Game Boy.
- Electronic immobilizer : A system in which a special chip embedded in a genuine key communicates with the vehicle’s computer and allows the engine to start only if authentication is successful. This system is said to significantly reduce the risk of theft, as the vehicle cannot be started by simply duplicating the key physically. However, it can still be disabled by a CAN invader or Game Boy.
- Auto alarm (intrusion sensor) : This detects unauthorized opening and closing of doors and windows, lifting of the vehicle, and glass breakage, and sounds an alarm to deter thieves. The alarm attracts the attention of those around and is effective in preventing theft, but it can easily be deactivated by electronic means such as relay attacks, CAN Invaders, and Game Boys, rendering it completely useless.
- T-Connect Alarm Notification (Vehicle Tracking System) : This system has a real-time location tracking function using GPS and a smartphone notification function when the auto alarm is activated. However, because it is controlled by CAN signals, if a key emulator (Game Boy) is used, the steering wheel lock and location search functions will also be disabled, and you may not even receive a notification that they have been disabled.
No matter how new security systems are developed, new methods are devised to break them, creating a constant “cat and mouse” game, making it difficult to completely prevent theft with factory security systems alone. While it is difficult for thieves to steal vehicles immediately after release, current systems have already been deciphered and exploited. Recently, dealers have been advising customers to “install their own security measures if they are worried about theft.” In fact, many vehicles with only factory security have been theft victims, and many owners are calling for stronger security in their newly purchased vehicles.
Theft prevention measures that are considered ineffective and the reality
Unfortunately, even if various theft prevention measures are taken in addition to genuine security measures, there are many cases where they are not sufficiently effective. The tactics of thieves are bolder and more forceful than people imagine, and ordinary measures can easily be bypassed.
- Steering wheel locks : These are devices that are attached to the steering wheel to prevent physical operation, but there have been reported cases where thieves have used saws or power tools to cut the steering wheel itself, disabling it in just a few tens of seconds. For this reason, steering wheel locks alone have limited effectiveness.
- Tire locks : These are physical anti-theft devices that are attached to the wheels of a vehicle to make it difficult to drive, but thieves may still drive away and destroy the locks themselves, so this alone is not an effective measure.
- Body Covers : Some people hope that covering the body of their vehicle will make it less noticeable and deter theft, but this can actually have the opposite effect. Because the inside of the cover is hidden from view, it can make it easier for thieves to use tools to access the vehicle, giving them a chance to slowly breach security.
These measures are not completely meaningless, but their effectiveness when used alone is limited, so you should not rely on them too much.
The strongest anti-theft measures to protect the new Alphard and Vellfire
So, what are the most effective measures to ensure the safety of your new Alphard or Vellfire? It is extremely important to combine multiple measures to create a multi-layered defense. Considering the cost-effectiveness of theft prevention measures and finding the one that suits you best will help you enjoy your car life with peace of mind.
A car security system that provides reliable protection
In order for a thief to start the engine, they need both the ignition and the starter motor to be operating. A security system that controls both of these systems and has the ability to prevent unauthorized engine starts is recommended as one of the most effective countermeasures. Installing an aftermarket car security system is undoubtedly the most effective solution.
- Car Security System
Effective physical measures and the use of IT technology
Combining advanced car security systems with physical measures and IT technology provides an additional layer of defense and significantly reduces the risk of theft.
Strengthening and combining physical measures
The aforementioned steering wheel locks, tire locks, and pedal locks have limited effectiveness when used individually, but using them in combination can slow down thieves and discourage them from attempting the crime. It is especially recommended to choose locks made from special alloys with high hardness that are resistant to cutting, or that have a strong visual appeal.
- Pedal lock : A pedal lock locks the brake pedal, preventing the engine from starting, gear changes, and starting the vehicle. When used in conjunction with a steering lock and tire lock, a pedal lock can provide near-perfect protection against physical theft. Thieves would need a lot of time to deactivate the pedal lock, significantly reducing the risk of theft.
- Parking Bollards & Garage Parking : One of the most recommended theft prevention measures is parking in a garage with a shutter. Even if this is not possible, installing parking bollards will physically block the vehicle’s path. There are types that can be easily installed with DIY, and physically blocking off the vehicle from the parking lot is an extremely effective theft prevention measure at home.
- Steering Lock : A classic anti-theft device, steering locks remain widely recognized as an effective theft deterrent due to their high visibility and physical barrier. Brightly colored and eye-catching steering locks act as a powerful psychological deterrent and physical barrier to thieves. When choosing a lock, pay attention to the strength of the material and the difficulty of breaking it.
IT-based tracking and monitoring
In case of an emergency, it is also important to introduce a system that can track the vehicle’s location.
- Signal-blocking case : A “signal-blocking case” that blocks the radio waves emitted by a smart key blocks the smart key’s remote signal, preventing theft by relay attacks. By using a signal-blocking smart key case when you go out and putting the key in the case when you come home, you can ensure security while your car is parked.
- Apple AirTag (+ Used iPhone) : By hiding an Apple AirTag in your car, you can check your vehicle’s current location in real time from your iPhone. AirTags do not use GPS, but rather rely on Bluetooth signals from hundreds of millions of Apple devices on the network to determine your location. This gives them the advantage of being able to pinpoint your exact location, even in tunnels or underground parking lots. AirTags are designed to notify the owner of your iPhone if their location is determined through a third party’s iPhone, posing a risk to thieves. To avoid this, we recommend using an unused old or used iPhone with a low-cost SIM card and leaving it in your car along with the AirTag. This allows your iPhone to obtain location information and share it with the AirTag, making it less likely to be detected by thieves.
- GPS Trackers : GPS trackers, also available for Android users, can help you locate your vehicle. They allow you to track your vehicle in real time, recording details of when it’s moving and when it’s parked, making them a very effective security measure.
- Security cameras : By installing a security camera in your home parking lot and connecting it via Wi-Fi, you can check the status of your Alphard or Vellfire from your smartphone or computer anytime, anywhere. Online cameras with multiple functions, such as recording, area intrusion detection, and human and motion detection, are a great deterrent when monitoring your parked vehicle. If you choose a camera that sends push notifications to your smartphone when it detects something, you can immediately detect any abnormalities.

Simple but effective prevention measures
One easy countermeasure is to use an “OBD guard” to prevent unauthorized connections to the vehicle. The OBD (On-Board Diagnostics) port is an interface used for vehicle diagnostics and maintenance, but thieves can also use this port to start the engine illegally. An OBD lock physically covers this port to prevent unauthorized access. It is particularly effective in luxury vehicles like the Alphard, and is easy to install and cost-effective. While commercially available products are available, another inexpensive yet effective method is to physically secure the OBD2 port on an Alphard or Vellfire with multiple cable ties. This makes connecting an unauthorized diagnostic device time-consuming, increasing the likelihood that a thief will give up. However, it is important to consider the time required to manually remove the OBD2 port when using it for vehicle diagnostics, etc.
Glass etching is also an effective anti-theft measure. This method involves etching the license plate number or vehicle identification number (VIN) into the vehicle’s window glass, making it more difficult to resell a stolen vehicle. While this can be done at a specialist shop, DIY kits are also available commercially and are relatively inexpensive.
The cost and effectiveness of anti-theft measures, and how to choose them
The cost of anti-theft measures for an Alphard varies greatly depending on the product and the combination of measures, but considering their effectiveness, they can be said to be a good investment. When considering the effectiveness of anti-theft measures, it is important to note the high theft risk of the Alphard. In the first half of 2024, 303 Alphards were stolen. Considering this situation, investing in appropriate anti-theft measures is an important investment that not only protects the safety of the vehicle, but also provides peace of mind to the owner.
Effective theft prevention measures are achieved by combining multiple measures rather than relying on a single product or system. For example, you can build a multi-layered defense system by adding advanced electronic security such as IGAL2+ or KEYLESSBLOCK PRO PLUS, which can be purchased at Autobacs, to the original security system, and then adding physical defenses such as a steering wheel lock.
If you take these comprehensive measures, the total cost may be around 200,000 to 300,000 yen, but considering the value of the Alphard and the risk of theft, this is by no means expensive. Furthermore, these measures may also lead to a reduction in vehicle insurance premiums, making them cost-effective in the long run.
When choosing which device to use, we recommend taking into consideration your personal usage, parking environment, budget, etc. Also, don’t forget to regularly check for new anti-theft technologies and products and upgrade as necessary.
Summary: Multi-layered defense ensures your car is protected
Due to their popularity and high resale value, the new Alphard and Vellfire are always easy targets for thieves. With sophisticated theft methods such as relay attacks, CAN Invaders, and Game Boys becoming rampant, the reality is that genuine security systems alone are not enough to protect your beloved car.
The most important thing to do to protect your beloved car is to implement a “multi-layered defense” that combines multiple theft prevention measures. Specifically, we strongly recommend installing a high-performance car security system such as Clifford or Pantera, which has a “double immobilizer” function that thieves hate the most, as the core of your defense, and then combining the following measures to add more layers of defense.
- Visual defense : By parking your car in a place that is out of sight of thieves, you can make it harder for them to target you in the first place. Using a garage with a shutter or, if that is not possible, installing bollards or other barriers is also effective.
- Physical defenses : Install multiple physical barriers, such as steering wheel locks, tire locks, and pedal locks, to slow down thieves.
- Tracking and monitoring system : Using Apple AirTags, GPS trackers, security cameras, etc., we will create an environment where the vehicle’s location can be identified in the event of theft.
By taking these measures, you can significantly reduce the risk of theft and protect your precious Alphard or Vellfire from thieves. Consider the optimal security measures based on the condition of your vehicle and your parking environment.
