Keys that are chipped Keys
If you own a car equipped with a chip key, it is probable that it must be programmed in order to function. These keys have an electronic microchip embedded within the head. It transmits a signal from the immobilizer to the mechanical ignition or proximity fob (car key) that is part of a push-to-start system. This process allows the car to verify that the key has a digital serial number that is compatible with the code that is stored in its computer. If it does the car will disable the immobilizer, allowing the engine to turn.
This technology is also known as "transponder" technology, and it is a major part of most modern automotive anti-theft systems. It was invented during World War 2 to combat the rise in car thefts. Since then it has been embraced by all major auto manufacturers.
A transponder-equipped key has a small circuit board inside that is powered by a small battery. When the key is inserted into the ignition, it emits a burst of electromagnetic energy that reaches the antenna ring (part of the immobilizer system found in many cars) via radio frequency. The chip receives the energy and responds by sending an unique identification code to the antenna ring.

Key Cards

While it may appear to be an insignificant device that will never be replaced by something more sophisticated, recent updates have made the use of the hands-free card easier and safer. It's not surprising that this accessory will still be found on nearly two out of three Renault vehicles by 2021.
The story of the hands-free card began in 2001 with the release of the renault clio key replacement Laguna II. At the time, the company's design team was searching for ways to make the car more user-friendly. During this time, Bernard Dumondel was staying in a hotel and realized that he could unlock his car using the magnetic card used in the room.
This was a turning point in the development of hands-free cards. In the years that followed, the technology grew ever more advanced, with Renault eventually offering an option that was compatible with the all the cars they had to offer.

Immobilisers
The immobiliser is an engine-disabling security system. It shuts down the car's engine when the key that is not the correct one is used. It uses a small circuit within the key fob to transmit a code directly to the electronic control unit (ECU) of the car. The ECU examines the code prior to starting the engine. It can also record information that can be useful for insurance investigations, warranty claims and troubleshooting technical issues.
