Key Cards Renault's hands-free card has arguably become one of the most recognised features in the history of cars. While it may seem like an insignificant technology that won't be replaced by anything more sophisticated, recent updates have made using the hands-free card even more convenient and secure. It's no wonder that this device will remain included on almost three out of Renault vehicles sold by 2021. The history 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. At the time, Bernard Dumondel was staying in a hotel and realised that he could unlock his car with the magnetic card used in the room. This was a pivotal moment in the development of the hands-free card. In the years following the technology became more advanced and Renault eventually offering the card that was compatible with the all the cars they offered. In this version the car would unlock when it detected that the card was close to it, and then lock when the card was removed from the vehicle. While the system was efficient, it didn't come without shortcomings. For instance, the lock only unlocks when the card is near to the vehicle, meant that some people accidentally locked their car while shopping for instance, or when trying to open the boot. The card's inclusion of an ignition key (in case it failed) meant that people might unintentionally start their car or turn on electrical equipment within the dashboard. Renault came up with a new hands-free card generation in 2015 to address these issues. This model is more efficient and comes with an entry system that is keyless and is less susceptible to interference from objects nearby. It is also more secure as it is harder to hack. In addition, the addition of an additional button on the card signifies that it is able to turn on the car's interior lighting, which is useful in dark parking areas. Immobilisers The immobiliser is an engine disabling security system. It shuts down the engine of the car when the wrong key is used. It uses a small circuit inside your key fob in order to transmit a code directly to the electronic control unit (ECU) of the car. The ECU verifies the code before it allows the engine to start. It also keeps track of information that could 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 decrease the number of stolen cars. A study by the Economic Journal revealed that immobilisers have reduced car thefts by 40% between 1995 and 2008. Nearly all modern vehicles are equipped with factory-installed immobilisers. These immobilisers are also widely available for older vehicles that don't have them. However, not all immobilisers are made equal. Certain immobilisers are vulnerable to encryption that can be re-enforced with simple tools and methods. Some are harder to crack, and only a professional using the vehicle's ECU can decode them. It could be the battery in your key fob that needs to be replaced if the immobiliser on your car isn't working. This can be a relatively simple task that you could do yourself. However, it's best to visit a mechanic and have the task performed by a trained professional. This will prevent any damage to the chip on your key fob, which enables it to connect with your car. Another reason that could cause an immobiliser that is not working properly is that your vehicle has had replacement keys or repairs to the ignition and fuel systems. This could cause issues by altering the coding sequence sent from the key to the ECU. Although factory-fitted and Thatcham approved immobilisers are highly effective in deterring thieves, they're not fool proof. Sophisticated criminals have managed to come up with ways to get to get around them, such as the process known as'relay theft' where thieves can take over the signal between your key and your car's technology. You can avoid this trickery by storing your key in a bag from Faraday that blocks signals when you're not driving.
