When you buy a vehicle, an anti-theft system sounds like a feature that should give you peace of mind.

But recent security research has revealed that some dealer-installed anti-theft devices may actually create a new security risk if they haven’t been updated. Researchers found that certain aftermarket systems installed by dealerships could allow attackers to unlock doors and even disable a vehicle using Bluetooth.

While the vulnerability has been addressed by the manufacturer, many drivers may not realize their vehicle has one of these systems installed.

Which Vehicles Could Be Affected?

According to researchers, many affected vehicles were sold through dealerships beginning in 2017.

Brands commonly associated with these dealer-installed systems include:

  • Honda
  • Toyota
  • Ford
  • Mazda
  • Jeep

Not every vehicle from these manufacturers is affected. The issue relates to specific dealer-installed security systems rather than the vehicles themselves.

How Can You Tell?

Many affected vehicles have a small sticker on the driver’s side window displaying names such as:

  • KARR
  • SWDS

If you notice one of these stickers, it’s worth contacting your dealership to ask whether your vehicle has received the latest software update.

Should You Be Worried?

There’s no need to panic.

The vulnerability requires someone to be within Bluetooth range of the vehicle, and a software update has already been released to address the issue.

However, it’s still a good reminder that today’s vehicles rely on both mechanical security and software security.

How to Protect Your Vehicle

No security system is perfect, but these habits can reduce your risk:

  • Lock your vehicle even when parked at home.
  • Park in well-lit areas whenever possible.
  • Remove valuables from plain sight.
  • Ask your dealership whether all software updates have been completed.
  • Consider additional physical theft deterrents for high-risk areas.

Final Thoughts

Modern vehicles are more secure than ever, but they also rely on increasingly sophisticated technology.

If your vehicle has a dealer-installed anti-theft system, taking a few minutes to confirm it’s fully updated could help protect your investment.

Sometimes the best security upgrade is simply making sure the one you already have is working as intended.
