This technology, also known as the “transponder”, is an essential component of modern automotive anti-theft system. It was created during World War 2 to combat the rise in car thefts. Since then it has been adopted by the major auto manufacturers. A transponder key is a tiny circuit board inside it that is powered by a tiny battery. When a key is put into the ignition, it releases an electromagnetic energy blast that will reach the antenna ring (part of the immobilizer system that is found in most cars) via radio frequency. The chip absorbs the energy and responds by sending an unique identification code to the antenna ring. The chip inside a transponder key extremely sensitive to mechanical shocks and to water.

Key Cards The hands-free card of Renault is arguably one of the most popular accessories in the history of automobiles. Recent updates have made the hands-free cards more secure and more convenient to use. It's no wonder that this feature is present on nearly two-thirds of Renault vehicles that will be sold in 2021. The story of the hands-free cards began in 2001 with the launch of the Renault Laguna II. The design team of the company was looking for ways to make the car more user-friendly to use. During this time, Bernard Dumondel was staying in a hotel when he realised that he could unlock his car by using the magnetic card used in the room. This was a pivotal moment in the development of the hands-free card. In the years to come the technology grew more advanced. Renault eventually offered a version compatible with their entire range of vehicles. In this version the car would unlock when it detected that the card was near it, and then lock when the card was moved away from the vehicle. While the system was efficient, it didn't come without its shortcomings. The fact that the card only unlocks the car when close to it, meant that some people locked their cars while shopping or trying to open the car's boot. Additionally, the fact the keycard had an ignition key within it (in case of failure) meant that drivers could unwittingly start their engine or turn on electrical devices on the dashboard even though they were not planning to. To resolve these issues, Renault developed a new generation of hands-free cards in the year 2015. This version is more efficient and comes with an efficient keyless entry system that is less vulnerable to interference from nearby objects. It is also more secure, as it is harder to hack. The card now has a second button that can be used to turn on the interior illumination of the car, which is very helpful in dark parking areas. Immobilisers The immobiliser is an engine-disabling security system. It disables the engine of the car when the wrong key is used. It works by using a microcircuit in your key fob to send a code to the car's electronic control unit (ECU). The ECU examines the code prior to starting the engine. It can also store information that is useful in insurance investigations, warranty claims and technical troubleshooting. Since the early 1990s Immobilisers have been used in cars and have helped in reducing the rate of car theft. In fact, a study published by the Economic Journal found that the immobilisers helped reduce thefts by about 40% between 1995 and 2008. Most modern vehicles are equipped with factory-installed immobilisers. They are also available for older vehicles that don't have them. All immobilisers, however, are created in the same way. Some have weak encryption that can be broken using simple tools and techniques. Others are more difficult to break and can only be accessed by a specialist with access to the vehicle's ECU. It could be a battery in your key fob that has to be replaced if the immobiliser on your vehicle isn't functioning. This can be a relatively easy job that you can do yourself. It's better to go to a mechanic to get the work done. This will ensure that there is no damage to the chip inside your key fob, which enables it to connect with your car. An immobiliser that is not working properly can be caused by replacement of keys or repairs made to your ignition, fuel and starter system. This could cause issues by altering the code sequence sent from the key to the ECU. Although factory-fitted and Thatcham approved immobilisers are extremely effective in deterring thieves however, they're not foolproof. Criminals with sophisticated skills have managed to develop ways to get around them, such as a technique known as'relay theft' where thieves can intercept the signal that is sent between your key and your car's technology. You can avoid this trickery by storing your keys in a Faraday bag which blocks signals when you are not driving.
