The car's computer is able to check that the serial number of the key matches the code stored in the computer. If it does the car will disable the immobilizer, allowing the engine to rotate. This technology, also known as the “transponder” is a key component of modern automotive anti-theft system. It was invented during World War 2 to combat the increase in car thefts. Since then it has been adopted by all major auto manufacturers. A transponder-equipped key has a small circuit board inside that is powered by a tiny battery. When keys are placed in the ignition, it emits a burst of electromagnetic energy that is received by the antenna ring (part of the immobilizer system in most cars) through radio frequency. The chip absorbs the energy and responds by sending a unique identification code back to the antenna ring. The chip in transponders is sensitive to mechanical shocks as well as water. Submerging the key in water or dropping it on any hard surface could cause damage to it. If you require the transponder to be duplicated only a locksmith who is licensed is the best person to handle the task.

Key Cards Renault's hands free card is among the most famous accessories in the history of automobiles. Recent updates have made the hands-free cards safer and more convenient to use. It's no wonder that this feature is available on more than two-thirds of Renault vehicles sold in 2021. The story of the hands-free cards began in 2001 with the launch of the Renault Laguna II. At the time, the company's design team was searching for a way to make the car more user-friendly. It was during this period that one of the designers, Bernard Dumondel, was staying in a hotel and realised that the magnetic card in use in the room could be used to unlock his car. This was a pivotal moment in the development of the hands-free card. In the years that followed, the technology grew ever more advanced and Renault eventually launching the card that was compatible with the entire range of cars they offered. In this version, when the car detected the card near it would open and then lock the vehicle again. The system was a huge success, but it did have certain issues. The fact that the card can only unlock the car when it is 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 contained an ignition key inside it (in case of failure) allowed people to unwittingly start their engine or turn on electrical devices on the dashboard even though they weren't expecting to. In order to resolve these issues, Renault developed a new generation of hands-free cards in the year 2015. This version is much more efficient and comes with an efficient keyless entry system that is less susceptible to interference from objects nearby. It is also more secure since it is much harder to hack.

Immobilisers The immobiliser is a safety device that shuts down your car's engine if the key that is not the correct one is used. It works by using a microcircuit in your key fob to send a code to the electronic control unit of your car (ECU). The ECU examines the code before it allows the engine to start. It also records information that can aid in insurance investigations and warranty claims as well as technical troubleshooting. Since the beginning of the 1990s immobilisers have been installed in cars and have helped to reduce car theft rates. In fact, a study by the Economic Journal found that the immobilisers helped reduce thefts by around 40% between 1995 and 2008. Immobilisers are fitted to almost all modern cars as standard. They are also available for older vehicles without them. However, not all immobilisers are made equal. Some immobilisers have weak encryption, which can be re-enforced with simple tools and techniques. Some are harder to break and only a specialist with the vehicle's ECU can break them. It could be the battery in your key fob that has to be replaced if the immobiliser in your vehicle isn't functioning. You can complete this task yourself. However, it's always better to head to an expert mechanic and have the task performed by a trained professional. This will ensure that there is no damage to the chip inside the key fob which allows it and your car to communicate with each other. An immobiliser that is not working properly can be caused by the replacement of keys or the repairs to your ignition, fuel and starter system. This can alter the coding sequence that is sent from your key to the ECU and create problems. Immobilisers that are installed in the factory and endorsed by Thatcham are extremely effective in deterring theft, but they're not 100% secure. The most sophisticated criminals have managed develop ways around them, including a technique known as'relay theft', where thieves take over the signal between your key and the car's technology. This trickery can be avoided by keeping your car's keys in a bag that blocks signals when you're not driving it.
