What is Passive Anti Theft System?
In today’s technology-driven world, car thieves have become more sophisticated, and traditional alarm systems alone are no longer enough to protect vehicles from theft. To combat this, Passive Anti-Theft Systems (PATS) have become increasingly popular. But what exactly is a Passive Anti-Theft System, and how does it work?
What is a Passive Anti-Theft System?
A Passive Anti-Theft System, also known as a Immobilizer or Kill Switch, is an electronic device installed in a vehicle that prevents the engine from starting if the key fob is not present or if it is stolen. The system uses rolling codes, a unique feature that changes the code used to communicate between the key fob and the immobilizer every time the fob is used.
How Does a Passive Anti-Theft System Work?
The following is a step-by-step explanation of how a Passive Anti-Theft System works:
• When the key fob is inserted into the ignition and the ignition switch is turned to the "start" position: The immobilizer system is activated, and the vehicle sends a query to the key fob.
• The key fob receives the query and responds with its own unique code: This code is generated using a one-time pad and is randomly changed every time the key fob is used.
• The immobilizer system verifies the code with the code stored in the immobilizer chip: If the codes match, the system allows the engine to start. If the codes do not match, the system prevents the engine from starting.
Benefits of a Passive Anti-Theft System
The benefits of a Passive Anti-Theft System are numerous:
• High level of security: PATS makes it impossible for thieves to hotwire or steal your vehicle by simply using a spare key.
• Prevents engine theft: Even if a thief gains access to your key, they will not be able to start the engine.
• Easy installation: PATS is relatively easy to install and can be done in a matter of hours by a qualified mechanic.
• Cost-effective: While the initial installation cost may seem high, PATS is a long-term solution that can save you thousands of dollars in potential car theft losses.
How to Choose the Right Passive Anti-Theft System for Your Vehicle
When selecting a PATS for your vehicle, consider the following factors:
• Vehicle compatibility: Ensure the system is compatible with your vehicle make and model.
• Type of system: Decide between a remote start and immobilizer system or a standalone immobilizer system.
• Code generation method: Choose a system with a secure code generation method, such as a rolling code.
• Anti-theft features: Look for additional anti-theft features, such as siren activation, alarm flashing, and engine immobilization.
• Warranty and support: Check the warranty and support offered by the manufacturer.
Table: Features to Consider When Choosing a Passive Anti-Theft System
