Renault Keys – How They Work
Renaults come with a complex system for immobilisers and keys. This can make replacing keys very slow. If you don’t have access the vehicle and are able to bring it in to us to be able to code it using the diagnostic socket it can be a very lengthy.
Keys
The Renault Group is primarily known for its vans, buses and tractors, but they also manufacture cars. It is a well-established business founded in 1899. They offer a vast variety of car models. If you lose your keys to your car or they are damaged, you will need a replacement key quickly. Instead of waiting for your local main dealer to order a new one for you and then wait for a longer time to receive it delivered, why not let us do it? We can replace your smart key or remote in a matter of minutes at 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 the Renault Kangoo, Traffic or Master key.
Renault has a long and rich history of innovation. It was the first company to implement remote central locking in production vehicles. Paul Lipschultz invented this technology for Niemens which is an automotive supplier of security components. This innovation was a huge leap for safety in cars.
Remotes
Hands-free cards from Renault are still used extensively in their vehicles, despite the fact that smartphones appear to be replacing them. In fact, they’re present in two out of three vehicles Renault sells, and their usage has increased in recent years. In this video, Pascaline of Renault’s products division discusses the primary components of these cards and how they function.
Renaults have a surprisingly complex immobiliser system, and it’s important to be aware of the basics before attempting to unlock a car without keys. Some vehicles have an emergency lock fitted to the door handle of the passenger which can be used in the event that keys stop working or the battery runs out. This is a good choice for those who don’t want to pay for a locksmith.
You’ll require a tool such as an ultra-thin jim or pump-up if you wish to remove the key fob. If you don’t have these tools, you could need to use a hammer and screwdriver in order to take off the cylinder.
You should be able to the passenger side and see a small lock inserted into the driver’s side panel close to the handle of the door. This is a safety feature to stop people from locking themselves inside their own vehicle or stealing the neighbour’s. This is a basic but effective security feature that can save you time and hassle when you need to quickly get into your vehicle.
Transponders
Transponders are used on many modern cars to safeguard against theft of cars. These tiny devices, which are connected to the key fob have a chip inside and can communicate with the car once it is within of. The chips utilize 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 code to the car. The unique code is then used to unlock the doors and then start the engine.
Similar technology was also used in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry continues to use this kind of chip message.
Up until recently, these systems were considered to be invulnerable to cloning. 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 not completely clone-proof. This has led a number of locksmiths in the auto industry to improve their knowledge by learning how to read and write these newer types of chips.
Immobilisers
Renaults are a bit complicated in regards to immobilisers and key systems. There are two main methods in use that affect the method by which 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. They are extremely delicate and require an experienced technician to identify and fix the issue if they fail.
The newer system is more user-friendly to use. It employs 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.
Certain models have an earpiece antenna that is specific to their vehicle and isn’t recognized by transponder scanners that are standard. This is very effective at keeping hotwiring off and is extremely difficult to disable using a standard key or an emulator for transponders. We have a product dubbed the Renault Antenna Emulator that we can use to disable this type of immobiliser on Renault Clio phase two models as well as on some Renault commercial vehicles that are equipped with ID46 Transponders. It replicates the operation of a valid key transponder within the ring antenna. renault replacement key card can be used to replace damaged or lost keys without disassembling the ECU. It has been approved and tested by Thatcham to provide additional peace of mind to motor insurance customers.
