Renault Keys – How They Work

Renaults have a sophisticated system of keys and immobilisers. This can make the process of replacing keys extremely time-consuming. If you do not have access to the car and can bring it in to us to be able to code it using the diagnostic socket, it will be a very lengthy.


The Renault group is known for its manufacturing of buses, vans, tractors and Lorries although they also manufacture cars. The company was founded in 1899. It is a large and well-established business with an array of automobile models. You’ll require a replacement key if you lose or damage your keys to your car. Why not let us buy one for you instead of waiting for your local dealer and then waiting for it to arrive? We can replace your smart key or remote fast by calling KeyNOW.

If you need a Renault Clio V, Captur 2 or New Zoe spare key we can provide you with a mechanical code number to order a new key through the dealer. We can also reset your Renault Kangoo Traffic or Master key.

Renault has a long history of innovation. It was the first company to have used remote central locking on a production car. Paul Lipschultz invented this technology for Niemens, an automotive supplier of security components. This breakthrough was a huge leap forward for car safety.


The hands-free cards of Renault are still widely used in their vehicles, despite the fact that smartphones are replacing them. In fact, two out of three Renault vehicles have hands-free cards. Their use has increased in recent years. In this video Pascaline from the Product Division of Renault explains how these cards work.

Renaults have a complex immobiliser, making it crucial to know the basics before attempting to unlock a car without the use of a key. Some vehicles will have an emergency lock installed to the handle of the passenger door, which can be used if the keys stop working or the battery runs out. This is an excellent option for those who don’t wish to pay for a locksmith.

You’ll require a device such as the slim jim or pump-up to remove the key fob. If you don’t own these tools, you may require an hammer and screwdriver to remove the key fob.

You should be able to walk into the passenger’s side and find a small lock that is inserted into the driver’s side panel next to the handle. This is a safety measure to prevent people from locking themselves inside their car or accidentally stealing their neighbor’s. This is a basic but efficient security feature that will save you time and stress when you need to get into your car.

renault zoe key are installed on many modern cars to protect against theft of cars. These tiny devices are attached to the key fob. They contain chips that communicate with the car whenever it is within of. These chips use a unique code to identify the key and tell it what vehicle it is associated with.

The chip transmits signals to a pair of coils which are placed around the ignition barrel of the vehicle. The coils are activated by the key and send an electromagnetic pulse to the chip. The chip responds by sending a unique identifier to the car. The unique code can then be used to unlock doors and begin the car.

Similar technology was employed in military planes during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry is still using this kind of chip message.

Up until recently the systems were thought to be secure against clones. 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 upgraded, and they no longer have replicable. This has led many locksmiths to upgrade their skills by learning to read, program and write these latest kinds.


Renaults are quite complicated in the way that they function when it comes to keys and immobilisers. There are two major systems in operation that affect the method by which a replacement key will be programmed to the car. The older system uses the “kill switch” that connects to one of the important car starting parts in order to turn it off if the right key is not present. These are delicate devices that require a technician to diagnose and fix them if they fail.

The newer system is simpler to use. It employs rolling security codes and advanced cryptography to defeat copying of the code from the key or ECU. This is the code that will be used to replace keys we supply.

Certain models feature an antenna ring that is specific to the vehicle and cannot be detected by transponder scanners that are standard. This is very effective at preventing hotwiring and is also extremely difficult to disable using a standard key or a transponder emulator. We have a specialist product dubbed the Renault Antenna Emulator (RAE) that can be used to disable this kind of immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles that are 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 to replace failed keys that are lost or stolen without dismantling the ECU. It has been tested and approved by Thatcham to give assurance to motor insurance customers.
