How Thieves Are Stealing Cars and How to Stop Them
Car theft has evolved far beyond the smash-and-grab tactics of the past. Today’s criminals use sophisticated technology to bypass modern security systems, often without leaving a trace. Understanding these new methods is the first step towards effective car theft prevention. This guide will walk you through how thieves are breaking into cars and what you can do to protect your vehicle with GPS trackers.
Keyless Entry Hacks: The Relay Attack
Many modern vehicles feature keyless entry for convenience, but this technology has also created a significant vulnerability. Thieves use a technique called a "relay attack" to exploit this system. It works with two devices: one captures the signal from your key fob inside your home, and the other relays it to your car parked outside.
This tricks your car into thinking the key is nearby, allowing the thief to unlock the doors and even start the engine. The entire process can take less than a minute, and the criminals don't need your physical keys to drive away.
Signal Jamming: The Silent Unlock
When you press the lock button on your remote, you expect your car to be secure. However, thieves can use a signal jammer to block the communication between your fob and your vehicle. You walk away believing your car is locked, but it remains vulnerable. The thief can then simply open the door and take any valuables inside or attempt to start the vehicle.
How to Prevent Signal Jamming
• Double-Check Manually: Make it a habit to physically check that your car is locked. After pressing the button on your remote, pull on a door handle to confirm it has engaged. Many modern cars also have visual cues, like folding mirrors, that confirm the vehicle is locked.
CAN Bus Attacks: Hacking Through the Headlights
One of the more alarming new methods is the Controller Area Network (CAN) bus attack. A vehicle's CAN bus is its central nervous system, connecting all its electronic components. Thieves have discovered they can access this network externally, often by removing a headlight or another accessible panel.
Once connected to the CAN bus, they can send commands to unlock the doors, disable the alarm, and start the engine. This method bypasses traditional security measures entirely, making it a powerful tool for high-tech criminals.
How to Prevent CAN Bus Attacks
• Install a Secondary Immobiliser: An aftermarket immobiliser adds another layer of security that a thief must bypass. It can prevent the engine from starting even if the main security system is compromised.
• Invest in a Vehicle Tracker: The most effective defence against this type of theft is a high-quality tracking system. If your car is stolen, a GPS tracker allows you to monitor its location in real-time, significantly increasing the chances of recovery. For robust security, consider professionally installed car trackers that are monitored 24/7.
Key Cloning: A Digital Copy of Your Key
Criminals don’t always need to hack your car; sometimes they just need a few moments with your key fob. During a valet service, car wash, or even at a less-than-reputable garage, a thief can use a device to clone the information from your key. Once they have this digital copy, they can create a new key that will work on your vehicle indefinitely.
How to Prevent Key Cloning
• Choose Reputable Services: Only use trusted and well-reviewed companies for maintenance, valeting, and parking.
• Be Mindful of Your Keys: Whenever possible, don't hand over your keys. If you must, ensure it's to a verified employee of a reputable business.
Don't Forget the Basics: Smash and Grab
While high-tech theft dominates the headlines, traditional methods still pose a threat. The simple "smash and grab" remains a common crime of opportunity. Thieves are often looking for quick and easy targets, and a bag, laptop, or phone left on a seat is an open invitation.
How to Prevent Smash and Grab Theft
• Keep Valuables Out of Sight: Never leave anything of value visible inside your car. This includes electronics, bags, coats, and even loose change. Store them in the boot or take them with you.
• Park in Secure Locations: Whenever possible, park in well-lit, busy areas. If you have a garage, use it.
The Ultimate Defence: GPS Vehicle Tracking
While prevention tips can deter thieves, a determined criminal may still find a way. The single most effective tool for recovering a stolen vehicle is a GPS tracker.
Modern GPS trackers provide real-time location data, allowing you and the police to track your vehicle's movements. Many systems also include features like geo-fencing, which alerts you if your car moves outside a designated area, and remote immobilisation. Investing in a high-quality, monitored car tracker is a proactive step that provides peace of mind and the best possible chance of getting your vehicle back safely.
By staying informed about the latest car theft methods and implementing these security measures, you can significantly reduce your risk and protect one of your most valuable assets.
