We are honored to announce that we achieved 2nd place in the recent Security Sales Contest!


While we have proudly earned 1st place multiple times in Car Audio Sales Contests, this is our very first time ranking among the top in the Security category.
There are many specialty shops dedicated solely to car security or car audio, but being recognized in both fields is the result of our unwavering commitment since the very beginning: “Never compromise on either car audio or security.” Reaching this milestone in our 25th anniversary year is something we are truly delighted with and deeply proud of.
Above all, this achievement was only possible thanks to the trust and support of our valued customers. We sincerely appreciate your continued patronage.
Although we finished in 2nd place this time, we will continue striving for 1st place, improving our technical expertise, and enhancing our services. All of our staff will keep giving their best efforts, and we look forward to your continued support!

Theft does not only happen at home. Build a setup that lets you notice — with sound and notifications

About the theft of the Land Cruiser 300 occurring nearby

There has been a theft of a Land Cruiser 300 at a home in Abiko City, Chiba Prefecture, as well as at a hotel parking lot in Noda City. Information has also been released by the manufacturer regarding damage to vehicles equipped with iGLA 2, so it’s a situation where you need to consider countermeasures both at home and when you’re out.

As of August 2026, we have not received any reports of theft damage for vehicles we have installed.
However, the method changes. We believe that this is not something you “install and it’s done”; you should review the necessary countermeasures while keeping an eye on the situation as it develops.

iGLA 2 / iGLA 2+ are still important countermeasures to prevent the vehicle from being moved unlawfully. At the same time, in places where it’s less likely to be noticed, it’s becoming increasingly important to layer measures that suppress the intrusion itself and measures that alert you to abnormalities with sound.

If we were to add to your current setup, I would prioritize the following first:

  • KEYLESS BLOCK JP+
    Countermeasures to suppress entry into the cabin

  • AUTHOR ALARM / GOLGO PANTHER A / SIREN BT
    Countermeasures to alert to abnormal activity with sound and create a situation where the intruder is less likely to stay on site

Depending on what else is needed, there is also an option to combine TELE COMPASS, which supports notifications and location confirmation. Operation may vary depending on the communication environment and vehicle condition, and you will need to subscribe separately.

You do not need to replace iGLA 2 / iGLA 2+. It’s fine to take the approach of keeping your current configuration and adding what’s missing. We’ll think together in a practical way while confirming your vehicle model and your current installed equipment.

Our current situation and my thoughts

As of August 2026, we have not received any reports of theft damage regarding vehicles we have installed.

The methods change every year. That’s why we, too, change every year.

To be honest, it’s the most heartbreaking for me if the customers we install on are victimized.

If someone is going to target a vehicle, please make it my car—not the customer’s. In that case, we will learn from it. That’s why we have demo cars.

Theft Information 2

Latest Auto Theft News and Public Information

At LOGON, we check auto theft news and public information that is likely to be relevant within roughly a 100 km radius of our shop, and we reflect this in our vehicle-specific security plan recommendations.

If you drive a Land Cruiser, Alphard, Lexus, HiAce, Crown, or similar model, please also check the theft trends for your vehicle and any warnings issued by public authorities. This is not intended to cause alarm, but to give you calm, practical information for thinking through measures suited to your parking environment and daily use.

Theft methods continue to change year by year, and locking your genuine key or relying on the factory security system alone can sometimes leave room for concern. As these cases show, incidents occur not only on your own property but also at hotels and car parks away from home, so it is important to combine "measures that sound an alarm on the spot" with "measures that let you notice even when you are away." LOGON's vehicle-specific security plans combine anti-theft starting measures, siren alarms, smartphone notifications, keyless countermeasures and analogue blocking, tailored to how you use and store your vehicle.

Please start by checking the plan for your vehicle model. We can also help with consultations and provisional reservations before your car is delivered, so please feel free to contact us even if the details are not yet decided.

A word from us (August 2026)

These thefts are happening close to our shop. Reports say that even vehicles already fitted with a security unit have been taken, and many owners are understandably uneasy.

As of August 2026, we have received no reports of theft involving any vehicle we have installed.

The methods change every year. So we change every year, too. We keep re-testing on our demo car and updating our setups.

What we recommend first is "do not let them in" (KEYLESS BLOCK JP+) and "sound the alarm on the spot" (AUTHOR ALARM / Grgo / PANTHERA / SIREN BT). If your budget allows, add TELE COMPASS so you can be alerted even when you are away.

Our customers come to us from many different starting points: those about to take delivery of a new car, those who have been targeted before, and those who had nothing fitted when they were hit. We have seen a number of vehicles after they were attacked, and each time we worked out how to prevent it and fed that back into how we install. That is why we never stop updating.
