Is Your Car Safe From Electronic Thieves? What Every Driver Needs to Know

Your remote keyless entry system may be convenient, but is it truly secure? As vehicle technology becomes more advanced, so do the methods used by criminals. Modern cars are equipped with wireless fobs and push-start systems—but these can be exploited using electronic tools that bypass keyless entry systems altogether.

The High-Tech Convenience of Keyless Entry

Most late-model vehicles now come with keyless entry and ignition systems. These allow drivers to unlock and start their cars without removing the fob from their pocket. When you approach the car, the system detects the fob, unlocks the doors, and enables the push-start ignition.

However, this wireless convenience creates new vulnerabilities—especially to a specific kind of tech-savvy thief.

How Thieves Use Electronic Scanner Boxes

Enter the scanner box: a compact black device that can intercept or guess the signal sent between your car and your key fob. This method, known as a “brute force” attack, involves trying thousands of frequency combinations until the correct one is found.

The result? A thief can unlock your car doors without breaking a window or sounding an alarm—sometimes in under 60 seconds. These devices are small, easy to carry, and often go unnoticed.

Car Break-Ins, Not Full Thefts – For Now

Most of these attacks only unlock the vehicle; they don’t start the engine. That means criminals aren’t stealing the car itself—they’re stealing what's inside. Electronics, cash, bags, and even identity documents are common targets.

Although full vehicle theft is still rare due to encrypted ignition systems, experts warn that it’s only a matter of time before push-start ignition systems become vulnerable as well.

Simple Ways to Protect Your Car and Belongings

• Never leave valuables like laptops, phones, or bags visible inside your car.
• Even cables or chargers suggest valuables are inside—hide or remove them.
• Always lock your doors and roll up your windows, even for quick stops.
• Park in well-lit and high-traffic areas whenever possible.
• Consider using a Faraday pouch to block wireless signals from your key fob.
• Don’t assume a high-tech car is automatically more secure—stay vigilant.

High-tech criminals require high-awareness drivers. As your car becomes more connected, it's critical to understand both the convenience and the potential vulnerabilities.
