What is a Theft Deterrent System?

A theft deterrent system is designed to make your car harder to steal. It is an alarm system, and it’s an immobilizer (makes it where your Camaro won’t start). The service theft deterrent system warning won’t make your Chevy Camaro’s alarm go off randomly, but it won’t be able to start.

Parts of a Theft Deterrent System
Depending on the model year, your Camaro will have some variation of the parts and sensors listed below.
- Immobilizer– An immobilizer is an anti-theft device installed in a vehicle. It uses electronic chips embedded in the key to send a signal that the car’s computer must recognize before it will start. This prevents unauthorized people from being able to start the vehicle and steal it.
- Vehicle Sensors– Newer, modern security sensors on a vehicle include motion sensors, which are triggered when the vehicle is moved; tilt sensors, which detect any change in the angle of the vehicle; and proximity sensors, which detect when someone is too close to the car. Additionally, infrared sensors can detect when a key fob is within range of the Chevy Camaro and will only unlock the doors if the right signal is sent. Hood latch, door lock, and key recognition sensors have existed for decades.
- Key Fob– Key fobs are an essential part of vehicle security, as they use advanced electronic chips embedded in the key to send a signal that must be recognized by the car’s computer before it will start. This ensures that only authorized users can unlock and start the vehicle, protecting it from theft.
