Why You Should Secure Your Car with a CAN Immobilizer

Protect Your Vehicle from Modern Theft Techniques

Car theft is becoming more sophisticated, with criminals using advanced techniques to bypass traditional security measures. Factory immobilizers and alarms often fail to protect against these new threats. One of the best ways to ensure your vehicle’s security is by installing a CAN Immobilizer.

This article explores the risks drivers face, why standard security systems are inadequate, and how the Carguard CAN Immobilizer offers top-tier protection.


The Biggest Threats to Your Car’s Security

Relay Attack: How Thieves Steal Cars Without a Key

One of the most common car theft methods is the relay attack, which allows criminals to unlock and start your car without needing your key.

How Relay Attack Works

  1. Two criminals work together, using signal-boosting devices.
  2. One thief captures the key’s signal from inside your home.
  3. The second thief transmits the signal near your car, tricking it into thinking the real key is present.
  4. The car unlocks and starts, allowing them to drive away unnoticed.

Key Cloning: Replicating Your Car’s Key

Car thieves can also clone your key fob using digital tools. Once a cloned key is made, they can unlock and drive your vehicle as if they owned it.

OBD Port Attacks: Reprogramming the Car’s System

Every modern vehicle has an On-Board Diagnostics (OBD) port, which thieves can exploit to program a new key and take control of your car in minutes.


Why a CAN Immobilizer is the Best Solution

How Does a CAN Immobilizer Work?

  • Blocks engine start – Even if thieves access your car, they cannot start the engine without proper authentication.
  • Prevents relay and key cloning attacks – The system does not rely on the key fob’s signal, making it immune to hacking.
  • Uses hidden authentication methods – Owners must enter a PIN using the vehicle’s built-in controls.
  • Invisible to thieves – The immobilizer does not emit detectable signals, making it impossible to locate or disable.
