Renault Keys - How They Work
Renaults use a rather complex system in the sense that the immobiliser and keys go. This makes the process of replacing keys very slow. It could take a lengthy time to code the car if you have access to it and can bring it to us.
Keys

Renault has a long record of innovation. It was the company that used remote central locking on a production car. This technology was invented by Paul Lipschultz for his employer Niemens, a supplier of security components to the automotive industry. This innovation was a huge leap in the field of car safety.
Remotes
Hands-free cards from Renault are still used extensively in their vehicles, despite the fact that smartphones are replacing them. In fact, they're included in two of the three vehicles Renault sells, and their use rate has been rising in recent years. In this video, Pascaline of Renault's products division explains the main components of these cards and how they work.
Renaults have an immobiliser mechanism that is a bit complicated. It's important to know the basics before attempting to unlock a vehicle without keys. Certain cars come with an emergency lock attached to the passenger door handle which can be used in the event that the keys stop working or the batteries are out. This is a solution for those who don't wish to hire a professional locksmith.
You'll also require access to a device such as an apex key or a slim jim in order to remove the key fob and gain access. If you do not have these tools, it may be necessary to use a hammer and screwdriver to take the cylinder out.
You will be able to step to the passenger side and see an insignificant lock placed on the side panel of the driver close to the handle of the door. This is a precautionary measure to stop thieves from accidentally taking an automobile or locking themselves to their own. It's a straightforward, yet effective security measure that could help you save time and effort in the event that you need to gain access to your vehicle quickly.
Transponders
Many modern vehicles use transponders to deter theft of cars. These small devices are connected to the key fob, and they contain chips that communicate with the car when it is within of. These chips employ a code to identify the car and key.
The chip sends signals 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 then responds by sending an identification code unique to the car. The unique code is then used to unlock the doors and start the engine.
Similar technology was also used in military planes during the World War 2 era to aid air traffic controllers in identifying them on radar. renault megane replacement key card uses this type of chip code message.
For a long time the systems were thought to be clone-proof. This was due to the fact that there were only 74 Quadrillion (74,000,000,000,000,000) possible codes for each transponder. But the technology behind these chips has since been improved and they are now no longer completely clone-proof. This has seen many auto locksmiths upgrade their skills by learning how to read, write and program these newer kinds.
Immobilisers
The Renault isn't the most straightforward when it comes to the key systems and immobilisers. There are two main systems that affect how the new key is programmed into the car. The older system uses an "kill switch" to disable a vital part of the car's starting mechanism if the proper key is not present. They are very delicate and require a trained technician to correctly determine and correct the issue if they fail.
The newer system is more user-friendly to use. It utilizes rolling security codes and advanced cryptography in order to stop copying of the code from the key or ECU. This is what will be used in the replacement keys that we supply.
Certain models feature rings that are specific to the vehicle and cannot be recognized by standard transponder scanners. This is a highly effective way to prevent hotwiring, and it is also very difficult to disable using the standard key or transponder emulator. We have a specialized product dubbed the Renault Antenna Emulator (RAE) that can be used to bypass this type of immobiliser in Renault Clio phase 2 models and some Renault commercial vehicles with ID46 transponders. It mimics the operation of a valid transponder within the ring antenna. It is able to be used for failed keys that are lost or stolen without dismantling the ECU. It has been approved and tested by Thatcham to give security to motor insurance customers.
