Renault Keys - How They Work
Renaults have a complex system of immobilisers and keys. This makes the process of replacing keys extremely time-consuming. It could take a long time to code the car if you have access to it and can bring it to us.
Keys
The Renault group is recognized as a producer of buses, vans, Lorries and tractors however they also manufacture cars. It is a reputable company that was founded in 1899. They have a wide variety of car models. You will need a new key if you have lost or damaged your car keys. Rather than waiting for your local main dealer to order a brand new one for you, and then wait for even longer to see it arrive, why not let us do it? We can replace your remote or smart key with ease at KeyNOW.
We can provide an electronic code to purchase an Renault Clio V spare key, Captur 2 spare key or New Zoe key from the dealer. We can also reset a Renault Kangoo, Traffic or Master key.
Renault has a long tradition of innovation. It was the first company to utilize remote central locking in production vehicles. Paul Lipschultz invented this technology for Niemens, an automotive supplier of security components. This invention was a giant leap for car safety.
Remotes
Despite the fact that smartphones are close to replacing them, the hands-free cards of Renault are still used extensively in their vehicles. renault master key replacement included in two of every three vehicles Renault sells, and their use has increased in recent years. In this video, Pascaline of Renault's products division explains the key components of these cards and explains how they function.
Renaults have an immobiliser feature which is quite complicated. It is crucial to know the basics before trying to unlock a vehicle without keys. Some vehicles will have an emergency lock attached to the handle on the door of the passenger and can be used in the event that keys stop functioning or the batteries wear out. This is a viable option for those who don't wish to hire a professional locksmith.
You'll require a tool such as an a-slim jim or pump-up to remove the key fob. If you don't have these tools it might be necessary to employ a screwdriver and hammer to remove the cylinder.
You should be able get into the passenger's side and you will see a tiny lock inserted in the driver's compartment next to the handle. This is a safety feature to prevent people from locking themselves inside their car or accidentally stealing a neighbour's. It's a simple but effective security measure that can help you save time and stress should you need to enter your vehicle quickly.
Transponders
A lot of modern cars have transponders to guard against theft of vehicles. These tiny devices are affixed to the key fob and include an electronic chip that communicates with the car whenever it is within the range. These chips use a distinct code to identify the key and then tell it which vehicle it's paired with.
The chip transmits signals to a pair of coils that are positioned around the ignition barrel of the vehicle. These coils are activated by the key and send an electromagnetic pulse to the chip. The chip then responds by sending an unique identification code to the car. The unique code will be used to unlock doors or start the car.
Similar technology was employed 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 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. However, the technology behind these chips has been upgraded and they are now no longer completely invulnerable to cloning. This has made many locksmiths in the auto industry to upgrade their skills by learning how to read, program, and write these more modern types.
Immobilisers
The Renault is a bit muddled in the area of key systems and immobilisers. There are two main systems that affect the way keys are programmed into the car. The older one uses the "kill switch" that connects to one of the crucial car starting parts in order to disable it if the right key is not present. They are extremely delicate and require an experienced technician to diagnose and rectify if they fail.
The newer system is easier to use. It utilizes rolling security codes and advanced cryptography to thwart copying of the code from the key or ECU. This is the code that will be used to replace keys that we supply.
Some models will even use an earpiece that cannot be detected by the standard transponder scanners and is unique to the vehicle. This is a very effective way to prevent hotwiring, and is also difficult to bypass with a standard key or transponder emulator. We have a device called the Renault Antenna Emulator that we can use to disable this type of immobiliser on Renault Clio phase two models and some Renault commercial vehicles with ID46 Transponders. It mimics the operation of a valid transponder within the ring antenna and can be used on failed keys, or lost keys, without having to dismantle the ECU. It has been tested and endorsed by Thatcham in order to provide further security to motor insurance customers.
