Renault Keys - How They Work
Renaults have a complicated system for immobilisers as well as keys. This can result in replacement keys being a long drawn out process. It may take a long time to code the car if you have access to it and bring it to us.
Keys
The Renault group is perhaps best known for its manufacturing of vans, buses, Lorries and tractors, but they also make cars. It is a well-established company that was established in 1899. They offer a wide range of car models. If you lose keys to your car or break them, you'll require a replacement key fast. Why not let us order one for you instead of waiting for your local dealer to do so and then waiting for it to arrive? We can replace your remote or smart key fast by calling KeyNOW.
If you require 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 keys such as a Renault Kangoo, Traffic or Master key.
Renault has a rich history of innovation. It was the first company to have used remote central locking on a production vehicle. 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
Despite the fact that smartphones are on the verge of replacing them, the hands-free cards of Renault continue to be widely used in their vehicles. They're actually included in two out of three vehicles Renault sells, and their usage rate has been rising in recent years. In this video Pascaline from Renault's Products Division explains how these cards work.
Renaults have an immobiliser feature that is quite complex. It is important to understand the basics before you try to unlock a vehicle without the use of a key. Some vehicles will have an emergency lock fitted to the handle on the door of the passenger that can be used in the event that the keys stop working or the batteries run out. This is a viable option for those who do not want to hire a locksmith professional.
You'll require a device such as the slim jim or pump-up if you wish to remove the key fob. If you don't have the tools, it may be necessary to utilize a screwdriver or hammer to remove the cylinder.
You should be able to walk into the passenger door and see an insignificant lock placed on the side panel of the driver close to the handle of the door. This is a safety measure to prevent people from locking themselves in their own vehicle or accidentally stealing a neighbor's. It's an easy, but effective security measure that can save you lots of time and stress when you have to enter your vehicle quickly.
Transponders
Transponders are used on many modern vehicles to guard against car theft. These tiny devices, that are attached to the key fob include a chip and can communicate with the car once it is within range. These chips employ a unique code to identify the key, and also tell it which vehicle it is linked with.
The chip sends signals to a pair of coils that are attached to the ignition barrel of the vehicle. These coils are activated when the key is within reach and transmit a pulse of electromagnetic energy to the transponder chip. The chip responds by sending a unique code to the car. The unique code will be used to unlock doors and open the car.
During renault car key , a similar technology was employed to help air traffic control officials identify military aircrafts using radar. This type of chip code messaging is still utilized today 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 improved and they are no longer clone proof. This has seen many auto locksmiths upgrade their skills by learning to read, write and program these newer types.
Immobilisers
Renaults are quite complex in how they operate when it comes to their keys and immobilisers. There are two broad methods in use that affect the way that a replacement key will be programmed to the car. The older system utilizes a "kill switch" to disable a vital part of the car's ignition mechanism if the proper key is not present. These are extremely delicate and will need a trained technician to correctly identify and fix the issue if they fail.
The latest system is simpler to use. It uses rolling security codes and advanced cryptography to prevent copying of the code from the key or ECU. This is the code that will be used to replace keys we provide.
Certain models feature a ring antenna that is specific to the vehicle and is not detected by standard transponder scanners. This is extremely effective in blocking hotwiring, and is extremely difficult to bypass using a standard keys or an emulator for transponders. We have a special product dubbed the Renault Antenna Emulator (RAE) that we can use to bypass this kind of immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles fitted with ID46 transponders. It mimics the operation of a functioning transponder inside the ring antenna and can be used to replace failed keys that are lost or stolen without dismantling the ECU. It has been tested and endorsed by Thatcham to offer additional peace of mind to motor insurance customers.
