Renault Keys - How They Work

Renaults have a complex system for immobilisers and keys. This can result in replacing keys taking a long drawn out process. Unless you have access to the vehicle and are able to bring it in for us to make a code using the diagnostic socket it can be a very lengthy.

Keys

The Renault Group is better known for its buses, vans and tractors, but they also produce cars. Established in 1899 it is a huge and well-established company with a huge range of cars. You'll require a replacement key if you have lost or damaged your car keys. Why not let us purchase 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 in a matter of minutes at KeyNOW.

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 the Renault Kangoo, Traffic or Master key.

Renault has a rich history of innovation. It was the first company to utilize remote central locking in a production vehicle. This technology was invented by Paul Lipschultz for his employer Niemens who was a supplier of security components to the automotive industry. This was a significant leap forward for car safety.

Remotes

The hands-free cards of Renault are still widely used in their vehicles despite the fact smartphones appear to be replacing them. In fact, two of three Renault vehicles come with hands-free cards. Their usage has also increased in recent years. In this video Pascaline from the Product Division of Renault explains how these cards function.

renault clio replacement key have an immobiliser mechanism which is quite complicated. It's important to know the basics before you try to unlock a car without the use of a key. Some vehicles have an emergency lock that is located on the passenger door handle that can be used in the case of an unreliable key or battery running out. This is a solution for those who don't want to pay a professional locksmith.

You'll need a tool such as an a-slim jim or pump-up in order to remove the key fob. If you do not have these tools, it may be necessary to make use of a screwdriver and hammer to take the cylinder out.

You should be able get into the passenger's compartment and see a tiny lock that is inserted into the driver's panel next to the handle. This is a safety measure to prevent people from stealing an automobile or locking themselves to their own. It's a simple but effective security feature that can save you time and stress in the event that you need to get into your car.

Transponders

Many modern vehicles use transponders to prevent car theft. These small devices, that are attached to the key fob, contain a chip that communicates with the car when it is within the range. The chips utilize a code to identify the car and key.

The chip transmits an electronic signal to a pair of coils that are fitted around the ignition barrel of the vehicle. The coils are activated when you turn the key and transmit an electromagnetic pulse to the chip. The chip responds by sending a unique identifier to the car. The unique code can then be used to unlock doors and start the car.

In World War 2, a similar technology was utilized to aid air traffic control detect military aircrafts using radar. This kind of chip code messaging is still utilized today in the aviation industry.

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. The technology behind these chips has been improved, and they no longer have replicable. This has prompted many auto locksmiths to upgrade their knowledge by learning how to read and write code for these more advanced chips.

Immobilisers

Renaults are quite complex in the way they function when it comes to their immobilisers as well as keys. There are two main systems that affect how a new key is programmed into the car. The older one uses a "kill switch" to disable a vital component of the car's start-up mechanism if the correct key is not present. These are very delicate and require a trained technician to correctly detect and fix the issue should they fail.

The newer system is much simpler 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.

Some models will even use a special ring antenna that cannot be detected by transponder scanners, and is exclusive to the vehicle. This is a highly effective way to prevent hotwiring, and is also difficult to disable using the standard key or transponder emulator. We have a product called the Renault Antenna Emulator that we can use to bypass this type immobiliser on Renault Clio phase 2 models and on some Renault commercial vehicles equipped with ID46 Transponders. It replicates the operation of a valid key transponder inside the ring antenna. It can be used to replace lost or failed keys without disassembling the ECU. It has been approved and tested by Thatcham to give security to motor insurance customers.
