Renault Keys - How They Work

Keys
The Renault group is perhaps better known as a manufacturer of buses, vans, Lorries and tractors but they do produce cars too. Established in 1899 it is a huge and well-established business with an array of automobile models. You will need a new key if you lose or damage your keys to your car.

Renault has a long tradition of innovation. It was the first company to use remote central locking in a production vehicle. Paul Lipschultz invented this technology for Niemens the automotive manufacturer of security components. This invention was a giant leap for car safety.
Remotes
Despite the fact that smartphones appear to be on the verge of replacing them, Renault's hands-free card are still used extensively in their vehicles. In fact, they're included in the majority of vehicles Renault sells, and their usage has increased in recent years. In this video, Pascaline of Renault's products division explains the main components of these cards and how they function.
Renaults come with an immobiliser system that is quite complex. It is important to understand the basics prior to trying to unlock a car without the use of a key. Some vehicles have an emergency lock attached to the handle of the passenger door, which can be used if the keys stop working or the battery runs out. This is an option for those who don't want to hire a locksmith professional.
You'll also require access to a tool such as a pump-up key or slim jim in order to dismantle the key fob and gain entry. If you don't have these tools it could be necessary to make use of a screwdriver and hammer to remove the cylinder.
You should be able into the passenger door and you will see an insignificant lock placed on the driver's side panel near the door handle. This is a safety measure to keep people from locking themselves inside their own vehicle or stealing the neighbour's. It's a simple but effective security measure that will save you a lot of time and effort when you have to enter your vehicle quickly.
Transponders
Transponders are a common feature in modern vehicles to prevent car theft. These small devices are fitted to the key fob, and they contain chips that communicate with the car whenever it is within the range. These chips use a code to identify the car and key.
The chip transmits an electrical signal to two coils that are attached to the ignition barrel of the vehicle. The coils are activated by the key and send a pulse electromagnetic energy to the chip. The chip responds by sending a unique identifier to the car. The unique code is used to unlock the doors, and to start the engine.
Similar technology was utilized in military planes during the World War 2 era to help air traffic controllers identify them on radar. This type of chip is still in use in the aviation industry.
These systems were thought to be clone proof 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 upgraded, and they are no longer clone-proof. This has led many locksmiths in the auto industry to improve their skills by learning to read and write code for these newer types of chips.
Immobilisers
The Renaults are very complicated in the way that they function when it comes to their immobilisers and keys. There are two broad systems in use that effect the method by which a replacement key will be programmed to the car. The older system utilizes an "kill switch" that connects to one of the essential car starting parts in order to disable it in the event that the correct key isn't present. They are extremely delicate and will need a trained technician to correctly determine and correct the issue if they fail.
The latest system is easier to use. It uses 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 provide.
Certain models even come with an exclusive ring antenna which is not detected by transponder scanners, and is exclusive to the vehicle. This is extremely effective in preventing hotwiring and is also very hard to bypass with a standard key or a transponder emulator. We have a device called the Renault Antenna Emulator that we can use to bypass this immobiliser on Renault Clio phase 2 models as well as on some Renault commercial vehicles that are equipped with ID46 Transponders. It works by mimicking operation of a valid transponder within the ring antenna. It can be used for failed or lost keys without dismantling the ECU. It has been tested by Thatcham and endorsed to provide further peace of mind for customers of motor insurance.
