Renault Keys – How They Work
Renaults come with a complex system for immobilisers as well as keys. This can make replacing keys extremely time-consuming. If you do not have access to the car and are able to bring it in for us to code through the diagnostic socket, it could be a lengthy.
The Renault Group is primarily known for its vans, buses and tractors, but they also manufacture cars. It is a well-established company which was established in 1899. They offer a vast selection of cars. You will need a new key in the event that you lose or damage your keys to your car. Why not let us order one for you instead of waiting for your local dealer to do so and then wait longer for it to arrive? We can replace your remote or smart key with ease at KeyNOW.
If you need a Renault Clio V, Captur 2 or New Zoe spare key we can provide you with a mechanical code to order a new key through the dealer. We can also reset your Renault Kangoo Traffic or Master key.
Renault has a long and rich history of innovation. It was the first company to have used remote central locking on a production car. This technology was invented by Paul Lipschultz for his employer Niemens which is a manufacturer of security components to the automotive industry. This breakthrough was a massive leap for car safety.
Despite smartphones seeming to be close to replacing their hands-free cards, the hand-free cards from Renault are still widely used in their vehicles. They’re actually included in the majority of vehicles Renault sells, and their use rate has been rising in recent years. In this video Pascaline from the division of Products at Renault explains how these cards function.
Renaults have a surprisingly complex immobiliser, making it important to be aware of the basics before attempting to unlock a car without keys. Certain cars come with an emergency lock that is attached to the door handle of the passenger that is a good option if keys stop working or the battery runs out. This is an option for those who aren’t able to hire a locksmith professional.
You’ll also need to have access to a device such as the pump-up key or slim jim in order to take the key fob off and gain entry. If you don’t own these tools, you could require a hammer and screwdriver in order to take off the cylinder.
You should be able to walk to the door for the passenger and find a small lock that is inserted into the driver’s panel next to the handle. This is a safety feature to ensure that people don’t lock themselves inside their vehicle or stealing the neighbour’s. It’s a simple but effective security measure that can save you a lot of time and stress in the event that you need to gain access to your vehicle quickly.
Transponders are a common feature on modern cars to safeguard against theft of cars. These tiny devices are attached to the key fob and include a chip that communicates with the car whenever it is within the range. These chips use a unique code to identify the key and inform it which vehicle it is paired with.
The chip sends an electronic signal to a pair of coils that are positioned around the ignition barrel of the vehicle. The coils are activated once the key is within range and transmit a pulse electromagnetic energy to the transponder chip. The chip responds by sending back a unique identification code to the car. The unique code is then used to unlock the doors, and to start the engine.
Similar technology was employed in military planes during the World War 2 era to aid air traffic controllers in identifying them on radar. The aviation industry still utilizes this type of chip code message.
These systems were thought to be clone proof up until recently. This was due to the fact that there were only 74 Quadrillion (74,000,000,000,000,000) possible codes for each transponder. The technology behind these chips was improved, and they no longer have duplicate-proof. This has made many auto locksmiths upgrade their skills by learning how to read, program and write these newer kinds.
The Renaults are rather complex in how they operate with regard to their keys and immobilisers. There are two main systems in use that effect the way that a replacement key is programmed to the car. The older system utilizes a “kill switch” to turn off a crucial part of the car’s ignition mechanism if the proper key is not present. These are delicate devices that require a specialist to identify and repair if they fail.
The latest system is simpler to use. It makes use of advanced encryption and rolling security codes to prevent copying the code from the ECU or key. This is what will be used on the replacement keys that we provide.
Some models use an earpiece antenna that is specific to the vehicle and is not recognized by transponder scanners that are standard. This is a highly effective way to prevent hotwiring, and is also difficult to bypass with a standard key or transponder emulator. We have a product dubbed the Renault Antenna Emulator that we can use to bypass this type immobiliser on Renault Clio phase 2 models as well as on some Renault commercial vehicles equipped with ID46 Transponders. It works by mimicking operation of a transponder that is valid in the ring antenna. It is able to be used on failed keys that are lost or stolen without dismantling the ECU. It has been tested and endorsed by Thatcham to give assurance to motor insurance customers.
