Renault Keys - How They Work
Renaults use a fairly complex system in the sense that the immobiliser and keys go. This makes the process of replacing keys extremely time-consuming. If you don't have access to the car and are able to bring it in to us to be able to code it using the diagnostic socket it can be very time consuming.
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 founded in 1899. They offer a wide range of car models. You will need a new key in the event that you have lost or damaged your car keys. Rather than waiting for your local main dealer to order a new one for you, and then wait for even longer to see it arrive, why not let us do it? KeyNOW is the only place where you can get a replacement. KeyNOW we can replace your remote or smart key for you very quickly.
We can provide an electronic code to purchase a Renault Clio V spare key, Captur 2 spare key or New Zoe key from the dealer. We can also reset your Renault Kangoo Traffic or Master key.
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 an automotive manufacturer of security components. This invention was a major leap in the direction of safety for cars.
Remotes
The hands-free cards offered by 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 usage rate has been rising in recent years. In this video, Pascaline of Renault's products division explains the key components of these cards and explains how they work.
Renaults have an immobiliser system which is quite complicated. It is essential to know the basics prior to trying to unlock your vehicle without keys. Certain cars come with an emergency lock attached to the handle of the passenger door, which is a good option if keys stop working or the batteries run out. This is a viable option for those who don't want to hire a locksmith professional.
You'll need a tool, such as an ultra-thin jim or pump-up to remove the key fob. If you don't have these tools, you may require a screwdriver and hammer to remove the cylinder.
You should be able to walk into the passenger door and you will see an unassuming lock that is inserted into the driver's side panel just next to the door handle. This is a measure of security to prevent people from stealing another vehicle or locking themselves to their own. It's a simple, but efficient security measure that can save you a lot 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 are attached to the key fob and contain a chip that communicates with the car when it is within of. The chips utilize a code to identify the car and key.
The chip sends a signal to a pair coils which are placed around the ignition barrel of the vehicle. The coils activate when the key is within reach and send a signal of electromagnetic energy to the transponder chip. The chip responds by sending a unique identifier to the car. The unique code is then used to unlock the doors, and to start the engine.
During World War 2, a similar technology was utilized to aid air traffic control to identify military aircrafts on radar. This type of chip code is still in use in the aviation industry.
Up until recently the systems were believed 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. The technology behind these chips has been improved and they no longer have replicable. renault key programming has led a number of auto locksmiths to upgrade their skills by learning to read, write and program these newer types of chips.
Immobilisers
The Renaults are very complicated in the way they operate when it comes to their immobilisers as well as keys. There are two main systems that affect the way the new key is programmed into the car. The older one uses a "kill switch" to disable a vital element of the car's starting mechanism if the correct key is not present. These are extremely delicate and will need an experienced technician to detect and fix the issue should they fail.
The latest system is easier 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 we provide.
Some models use a ring antenna that is specific to their vehicle and cannot be recognized by standard transponder scanners. This is very effective at blocking hotwiring, and is extremely difficult to bypass using a standard keys or an emulator for transponders. We have a product known as the Renault Antenna Emulator that we can use in order to disable this type of immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles with ID46 Transponders. It mimics the operation of a valid key transponder inside the ring antenna. It can be used to replace lost or failed keys without the need to disassemble the ECU. It has been tested and endorsed by Thatcham to offer additional security to motor insurance customers.
