Renault Clio Key Fob Replacement It's time to replace your Renault Clio card if the buttons on the fob's key stop functioning, or if the card is no longer able to lock/unlock the car or even start it. Dealers or locksmiths are the best suited to do this job. New car dealers have the costly equipment required to program digital key fobs. Check your warranty or car insurance policy to see if this service is covered. Chipped Keys It is probable that your car's chip key will need to be programmed to function. Keys with chip technology contain an electronic microchip that is embedded into the head of the car key that transmits a signal to the immobilizer when inserted into the mechanical ignition or proximity FOB (car fob) that is part of a push to start system in some vehicles. This allows the car's computer to verify that the digital serial number of the key matches the code stored in the computer. If it does, the car will then disengage the immobilizer and allow the engine to rotate. This technology, also known as the “transponder” is a crucial component of the modern-day anti-theft systems in cars. It was created during World War 2 to combat the rise in car thefts. Since then it has been embraced by major auto makers. A transponder-equipped key includes a small circuit board inside that is powered by a tiny battery. When a key is inserted into the ignition, it sends electromagnetic energy to the antenna ring part of the immobilizer systems found in most automobiles. The chip is able to receive the energy and responds by sending an identification code unique to the antenna ring. The chip inside a transponder key extremely sensitive to mechanical shocks and to water. Submerging the key in water or dropping it on any hard surface could cause damage to it. In this case the fact that you have transponder keys that need to be duplicated, only let a certified locksmith handle it. If you're struggling with a damaged or chipped key, the best option is to get in touch with a professional mobile auto locksmith like Pop-A-Lock.

You can also find a replacement for a second-hand fob for less than you'd think. Contact them to inquire about the alternatives you have. Key Cards The hands-free device from Renault has become one of the most recognizable accessories in automotive history. Recent updates have made the hands-free cards more secure and more user-friendly. It's no wonder that this device will remain present on two out of three Renault vehicles sold by 2021. The history of the hands-free card began in 2001, following the introduction 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 time that one of the designers, Bernard Dumondel, was staying in a hotel and realised that the magnetic card he was using in the room could be used to unlock his car. It was a turning point in the development of hand-free cards. 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, when the car detected the card near the card would be unlocked and then lock the vehicle again. The system was a great success, but it had some imperfections. The fact that the card will only unlock the car when close to it, meant that some people locked their cars while shopping or trying to open the car's boot. The card's inclusion of an ignition key (in case it failed) meant that people might mistakenly start their car, or turn on electrical equipment within the dashboard. To address these issues, Renault developed a new generation of hands-free cards in 2015. This version is far more efficient and comes with an efficient keyless entry system that is less prone to interference from nearby objects. It is also more secure as it is harder to hack. The card now has an additional button that can be used to switch on the interior illumination of the car, which is very useful in dark parking areas. Immobilisers The immobiliser functions as an engine-disabling security system. It disables the engine of the car if the key is used in the wrong way. It utilizes a microcircuit within your key fob to send a code to the electronic control unit in your car (ECU). The ECU verifies the code before allowing the engine to start. It also records data that can help with insurance investigations as well as warranty claims and technical troubleshooting. Immobilisers have been used 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 about 40% between 1995 and 2008. Immobilisers come with almost all modern cars as standard. Immobilisers are also available for older vehicles that do not have them. All immobilisers, however they aren't all created to be the same. Some immobilisers use weak encryption, which is easily accessed using simple tools and techniques. Some are more difficult to crack and can only be decoded by a professional with access to the vehicle's ECU. If your car's immobiliser doesn't seem to be functioning properly, it could mean that the battery in the key fob is in need of replacement. You can complete this task yourself. However, it's always better to visit an expert mechanic and have the job done by a qualified professional. This will ensure that no damage is caused to the chip inside the key fob which allows it and your car to communicate with each other. Another possible reason for an immobiliser malfunctioning is that your car has had replacement keys or repairs to the ignition, fuel and starter motor systems. This can cause problems by altering the code sequence sent from the key to the ECU. Although factory-fitted and Thatcham approved immobilisers are incredibly effective in preventing thieves from entering your car, they're not fool proof. The most sophisticated criminals have managed develop ways to circumvent them, including a process called 'relay theft' where thieves can intercept the signal between your key and your car's electronic system. You can ward off this tactic by storing your key in a Faraday bag which blocks signals when not driving. Keys Replacement The cost of replacing a key fob will vary depending on the type of vehicle you own. If you own mechanical keys that don't include any electronic components, the price will be modest. A simple copy of a key made from metal can be created at the hardware store for less than $50. Many modern cars use keys that have a chip and immobilizer. The chips communicate with the vehicle and verify that the key is valid which allows you to lock or open the doors. The chip also turns on the ignition in your car. This is why it's so important to keep an extra key. If you have a spare key you can replace the lost or damaged fob and begin driving again. You can also buy aftermarket key fobs for less than the dealer keys. These are not as compatible with the car you drive. Batteries Plus is a great place to go if you want to replace the damaged key or purchase an additional. The store can help you find the right part and will have it ready for you to purchase in a matter of minutes. A locksmith can also reprogramme an existing key fob. There are online resources that can guide you through the process. But, it's an intricate job that should be performed by an experienced technician in the field. If you have spare keys, this is a great alternative as it will save some money. Some cars allow you to summon your vehicle by pressing the button on the key fob. G28 Car Keys is very useful in the event that your car is in an awkward spot and you don't want it to be able to move. This technology is becoming more popular, and you should consider it if you're looking to purchase a new car. It's recommended to get an extra Renault key fob, if you own one. These devices aren't only useful, but they also assist you in avoiding costly repairs in the event that your car breaks down.
