The Immobilizer System

The other two were more difficult to crack however they did eventually get broken.
The Immobilizer Chip
A chipped key is also referred to as a Smart Key, has a RFID microchip which transmits an encrypted passcode from the key to the immobilizer system of the vehicle. If the chip's code matches the system of the car the car will begin to move.
This is an essential anti-theft measure that prevents car thieves from hotwiring the immobilizer, or bypassing it in any other way. If the immobilizer fails to recognize the key, the engine will not start even if a person attempts to short-circuit ignition circuit.

Most modern cars have advanced electronic Engine Immobilizer systems that employ shifting or rolling security codes. The system's intelligent algorithm will alter the second code each time the key is used and push it into the chip of the key.

The unique approach of Peugeot's 206 was that it would not directly replace the 205 but it was designed to sit between the smaller Peugeot 106 and the larger 306 range. The lower models of both Peugeot 306 and 106 were created to take the sales of the more expensive 205s.
The 206 line-up includes three models including one hatchback (206 CC) as well as a cabriolet 2-door coupe, and a station wagon (206 SW). There was also an WRC homologated version of the 206 known as the 207 GTi that could reach 0-100 km/h in 7.4 seconds and an top speed of 210 km/h.
