Renault Clio Key Fob Replacement It is time to replace your Renault Clio card if the buttons on the fob's key stop working, or if your card no longer allows you to lock or unlock the car, or even start it. Dealers or locksmiths are the most qualified to complete this task. New car dealers have the costly equipment required to program digital key fobs. Check your warranty or car insurance policy to determine if this service is covered. Keys that are chipped Keys It is probable that your car's chip key will need to be programmed in order to function. The keys are equipped with an electronic microchip within the head. This sends 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 a digital serial number that matches the code stored in its computer. If it does the car will disengage the immobilizer and allow the engine to turn over. This technology is also referred to as “transponder” technology and is a major component of modern anti-theft systems. It was invented during World War 2 to combat the increase in car thefts. Since then, it has been adopted by the major auto manufacturers. A key that is equipped with a transponder has a small circuitboard that is powered by a small battery. When a key is inserted into the ignition sends a burst electromagnetic energy to the antenna ring, part of the immobilizer systems of most automobiles. The chip is able to receive the energy and responds by transmitting an identification code unique to the antenna ring. The chip inside transponders is sensitive to mechanical shocks as well as water. Dropping it on a hard surface can cause damage to it and submerging it in water can damage the chip, rendering it inoperable. Because of this the fact that you have transponder keys that need to be duplicated, you should only let a licensed locksmith handle it. Contacting an auto locksmith that is mobile, such as Pop-A-Lock, is the best option for those who are struggling with a car key that is chipped. These specialists can program and cut all new transponder keys as well as flip remote keys and Proximity Fobs at your location. renault car keys can also repair an old FOB for less than you expect, so it's worthwhile calling them to find out what alternatives are available to you. 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 insignificant device that is unlikely to be replaced by anything more advanced, recent enhancements have made using the hands-free card even more convenient and secure. It's not a surprise that this device is available on more than three out of Renault vehicles sold in 2021. The story of the hands-free card began in 2001, with the introduction of the Renault Laguna II. The design team of the company was searching for ways to make the car more user-friendly to use. It was during this period that one of the designers, Bernard Dumondel, was staying in a hotel when he realized that the magnetic card he was using in the room could be used to unlock his car. This was a turning point in the development of hand-free cards. In the years following the technology became more advanced and Renault eventually offering a version that was compatible with their entire range of cars they had to offer. In this version, the car would unlock when it sensed that the card was near it and then lock again when the card was removed from the vehicle. The system was a huge success, but it had certain flaws. The fact that the card only unlocks the car when it is close to it, meant that people could lock their cars while shopping or 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. To resolve these issues, Renault developed a new generation of hands-free cards in 2015. This version is far more efficient and comes with a more efficient keyless entry system that is less susceptible to interference from objects nearby. It is also more secure, as it is harder to hack. The card has an additional button that can be used to switch on the interior lighting of the car, which is very helpful in dark parking areas. Immobilisers The immobiliser is an engine disabling security system. It shuts down the engine of the car if the wrong key is used. It works by using a small circuit inside your key fob to send a code directly to the electronic control unit (ECU) of the car. The ECU is able to verify the code before permitting it to start the engine. It also records information that could aid in insurance investigations, warranty claims and technical troubleshooting. Immobilisers have been in use in cars since the early 1990s and have reduced car theft rates significantly. In fact, a study conducted by the Economic Journal found that the use of immobilisers reduced thefts by around 40% between 1995 and 2008. Most modern vehicles are fitted with factory-fitted immobilisers. They're also readily available as add-ons for older vehicles that weren't constructed with them. Not all immobilisers, however, are created in the same way. Certain immobilisers are vulnerable to encryption that can be re-enforced with simple tools and methods. Certain encryptions are more difficult to break and only a specialist with the vehicle's ECU can decode them. If your car's immobiliser isn't functioning properly, it could mean that the battery in the key fob is in need of replacement. It's an simple task that you could do yourself. It is best to take your car to an expert mechanic to get the work done. This will prevent any damage to the chip inside your key fob, which enables it to connect with your vehicle. Another reason for a faulty immobiliser is that your vehicle has been repaired or replaced with keys to the ignition, fuel and starter motor systems. This can alter the coding sequence sent from your key to the ECU and create problems. Although factory-fitted and Thatcham approved immobilisers are highly effective in deterring thieves but they're not foolproof. Sophisticated criminals have managed to develop ways around them, including a process called 'relay theft' where thieves can intercept the signal between your key and your car's electronic system. This scam is avoided by storing your car's key in a signal-blocking Faraday bag when you're not driving it. Replacement Keys The cost of replacing a key fob can vary based on the type of car you drive. If you have mechanical keys that don't contain any electronic components, the price will be modest. Hardware stores can create simple copies of a key for less than $50. On the other hand, most modern cars use a key fob that contains a chip and an immobilizer. These chips connect with the vehicle and confirm that the key is valid, allowing you to lock or unlock the doors. The chip also turns on the ignition of your car. This is why it's important to keep a spare key. If you have an extra key you can swap it for the lost or damaged fob and get back to driving. You can also buy aftermarket key fobs at a lower cost than dealer replacement keys. However, these aren't as compatible with your vehicle. Batteries Plus is a great location to visit in case you need to replace a damaged key or add a spare. The store can help you find the right part and will have it available for you to pick up in a matter of minutes. Another alternative is to let a locksmith reprogramme your existing key fob. A few online resources can help you through the procedure. However, it is an extremely complex task that should be performed by an experienced automotive technician. This is an ideal option if have a spare. It can save you money. Certain cars let you call your vehicle by pressing the button on the key fob. This feature is extremely helpful when your car is in a shady place and you don't want to run. This technology is becoming more popular and is worth a look in the event you're thinking of purchasing a new car. It's recommended to get an extra Renault key fob, if you own one. These devices are not only convenient, but can also help you avoid expensive repairs if your car breaks down.
