Keys with electronic microchip embedded in the head. This transmits an immobilizer signal to the mechanical ignition or proximity fob (car key) which is part of a push-to-start system. This process lets the car verify that the key has an electronic serial number that is compatible with the code stored in its computer. If it does the car will disengage the immobilizer and allow the engine to rotate. This technology, also known as the “transponder”, is an essential component of modern automotive anti-theft system. It was developed in World War 2 to combat the rising number of car thefts. Since then it has been embraced by the 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 sends out a burst of electromagnetic energy that will reach the antenna ring (part of the immobilizer system in most cars) via radio frequency. The chip absorbs this energy, and it responds by sending an unique identification code to the antenna ring. The chip in a transponder is susceptible to mechanical shocks, as well as water. Submerging the key in water or dropping it on any hard surface could damage it. This is why the fact that you have transponder keys that need to be duplicated, only let a locksmith who is licensed handle it. If you're having trouble with a chipped key, the best option is to call an auto locksmith professional like Pop-A-Lock. They can program and cut the majority of new transponder keys, flip remote keys and proximity fobs on-site at your location. You can also obtain an exchange for a secondhand fob at a cheaper price than you would expect. Contact them to find out what alternatives you have. Key Cards Renault's hands-free card has arguably become one of the most recognised accessories in automotive history. Although it might seem like an unimportant piece of technology that will never be replaced by something more sophisticated, recent improvements have made using the hands-free card even easier and safer. It's no wonder this device will remain present on three out of Renault vehicles by 2021. The first hands-free card was introduced in 2001, following the launch 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 at a hotel when he realized that he could unlock his car using the magnetic card that was used in the room. This was a turning-point in the development of hand-free cards. In the years that followed, the technology became 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 close to it, and then lock when the card was moved away from the vehicle. The system was a huge success, but it also had some issues. The fact that the card only unlocks the car when close to it meant that people could lock their cars while shopping or trying to open the boot. Additionally, the fact that the keycard had an ignition key in it (in case of failure) meant that people could without knowing it, start their engine, or activate electrical equipment on the dashboard while they weren't expecting to. To resolve these problems, Renault developed a new generation of hands-free card in 2015. This version is more efficient and comes with a more efficient keyless entry system that is less vulnerable to interference from nearby objects. It is also more secure, as it is harder to hack. In addition, the addition of an additional button on the card indicates that it can be used to turn on the car's interior lighting, which is useful in dark parking areas. Immobilisers The immobiliser functions as an engine-disabling security system. It disables the engine of the car if the wrong key is used. It works by using a small circuit within the key fob to transmit a code directly to the electronic control unit of the car. The ECU examines the code prior to allowing it to start the engine. It can also record information that is useful in insurance investigation, warranty claims, and troubleshooting technical issues. Since the beginning of 1990, immobilisers are used in cars and have helped to reduce car theft rates. A study conducted by the Economic Journal revealed that immobilisers have reduced thefts of cars by 40% between 1995 and 2008. Most modern vehicles are fitted with factory-fitted immobilisers. They are also available for older vehicles without them. However, not all immobilisers are designed equally. Some immobilisers have weak encryption that is easily accessed using simple tools and methods. Others are more difficult to break and can only be accessed by a specialist with access to the vehicle's ECU. If the immobiliser in your car isn't functioning correctly, it could be that the battery in the key fob requires replacement. You can perform this task yourself. However, it's better to head to a mechanic and have the work completed by a professional with experience. This will ensure that there is no damage to the chip inside your key fob, which allows it to communicate with your car. Another possible reason for an immobiliser malfunctioning is that your vehicle has been through repairs or replacement keys to the ignition and fuel systems. renault key card replacement cost could alter the coding sequence that is transmitted from your key to the ECU and cause issues. Although factory-fitted and Thatcham approved immobilisers are incredibly effective in deterring thieves but they're not foolproof. The most sophisticated criminals have managed come up with ways to get to circumvent them, including a process called 'relay theft' in which thieves intercept the signal between your keys and your car's technology. This scam is avoided by storing your car's keys in a signal-blocking Faraday bag when you're not driving it. Replacement Keys If you lose the car key fob, the cost of a new one will depend on what kind of car it is. If you have a mechanical car key that does not contain any electronic components and the cost is low. A simple duplicate of a mechanical key can be created at the hardware store for less than $50. Many modern cars use keys that have an immobilizer and chip. The chips communicate with the vehicle and verify that the key is genuine, allowing you to lock or unlock the doors. The chip also activates the ignition in your car. It is essential to have an extra key. If you have an extra key you can swap it for the lost or damaged fob and then get back on the road.
