renault replacement key card - How They Work

Renaults use a rather complicated system as far as the immobiliser and keys are concerned. This can result in replacement keys being a lengthy drawn out process. Unless you have access to your vehicle and bring it in to us to be able to code it using the diagnostic socket, it will be very time consuming.





Keys

The Renault group is probably better recognized as a producer of buses, vans Lorries and tractors but they also manufacture cars. Established in 1899 it is a large and well-established business with an array of automobile models. You'll need a new key in the event that you lose or damage your car keys. Why not let us buy one for you instead of waiting for your local dealer to do so and then waiting for it to arrive? We can replace your smart key or remote fast by calling KeyNOW.

If you need a Renault Clio V, Captur 2 or New Zoe spare key we can provide you with a mechanical code to purchase a new key through the dealer. We can also reset the Renault Kangoo, Traffic or Master key.

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

Remotes

Despite the fact that smartphones are close to replacing them, Renault's hands-free card continue to be used widely in their vehicles. In fact, two of three Renault vehicles come with hands-free cards. The use of these cards has increased in recent years. In this video, Pascaline of Renault's products division explains the most important components of these cards and how they function.

Renaults have an immobiliser mechanism that is a bit complicated. It's important to know the basics before trying to unlock a vehicle without a key. Some vehicles will have an emergency lock fitted to the handle on the door of the passenger and can be used if the keys stop working or the batteries are out. This is a viable option for those who do not want to hire a professional locksmith.

You'll also need to have access to a device such as an apex key or a slim jim in order to dismantle the key fob and gain entry. If you do not have these tools, it could be necessary to employ a screwdriver and hammer to remove the cylinder.

You will be able to step through the passenger door and find a small lock inserted into the driver's side panel near the door handle. This is a precautionary measure to prevent individuals from accidentally stealing other vehicles or locking themselves to their own. This is a simple, but efficient security feature that will help you save time and effort when you need to quickly get into your vehicle.

Transponders

Transponders are installed on many modern cars to protect against theft of cars. These small devices, which are attached to the key fob include a chip and can communicate with the car once it is within of. These chips utilize a number to identify the car and key.

The chip emits a signal that is picked up by a pair of coils fitted around the ignition barrel in the vehicle. These coils are activated by the key and send a pulse electromagnetic energy to the chip. The chip responds by sending a unique identification to the car. The unique code is then used to unlock the doors and start the engine.

A similar technology was used in military aircraft during the World War 2 era to aid air traffic controllers in identifying them on radar. The aviation industry still uses this type of chip code message.

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 improved and they are not completely duplicate-proof. This has led a number of locksmiths in the auto industry to improve their knowledge by learning how to read and write code for these modern chips.

Immobilisers

The Renaults are rather complex in how they operate when it comes to their keys and immobilisers. There are two main mechanisms that affect how keys are programmed into the car. The older system employs an "kill switch" that connects to one of the crucial car's starting components in order to disable it in the event that the correct key isn't present. They are extremely delicate and will need a skilled technician to identify and fix the issue if they fail.

The newer system is simpler to use. It utilizes rolling security codes and advanced cryptography to defeat copying of the code from the key or ECU. This is the code that will be used to replace keys we supply.

Some models will even use an extra ring antenna that can't be detected by the standard transponder scanners and is unique to the vehicle. This is very effective at preventing hotwiring and is also very difficult to get rid of using a standard keys or a transponder emulator. We have a device called the Renault Antenna Emulator that we can use in order to bypass this type immobiliser on Renault Clio phase two models as well as on some Renault commercial vehicles equipped with ID46 Transponders. It mimics the operation of a functioning transponder inside the ring antenna. It can be used for failed keys that are lost or stolen without dismantling the ECU. It is Thatcham tested and approved to offer additional security for motor insurance customers.
