Renault Keys - How They Work
Renaults use a rather complicated system in terms of the immobiliser and keys go. This can lead to keys replacement being a lengthy drawn out process. It may take a long time to code your car unless you have access to it and can bring it to us.

Renault has a long tradition of innovation. It was the company that utilized remote central locking on a production car. 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
Renault's hands free cards are still used extensively in their vehicles despite the fact that smartphones are replacing them. In fact, they're used in the majority of vehicles Renault sells and their use rate has been rising in recent years. In this video, Pascaline of Renault's products division explains the most important components of these cards and how they work.
Renaults have a surprisingly complex immobiliser system, which is why it's essential to know the basics before attempting to unlock a car without keys. Some cars come with an emergency lock on the passenger door handle that can be used in the case of a key failure or a battery runout. This is an excellent option for those who do not want to pay for a locksmith.
You'll also need to have access to a tool such as a pump-up key or slim jim to take the key fob off and gain access. If you don't have these tools, you may need to use an hammer and screwdriver to remove the cylinder.
You should be able to go to the door for the passenger and see a small lock that is inserted into the driver's compartment next to the handle. This is a security feature to ensure that people don't lock themselves inside their car or accidentally stealing a neighbour's. It's an easy, but effective security measure that could save you lots of time and stress in the event that you need to gain access to your vehicle quickly.
Transponders
Transponders are installed on many modern cars to protect against car theft. These small devices are connected to the key fob and contain an electronic chip that communicates with the car whenever it is within the range. These chips use a unique code to identify the key and then tell it which vehicle it is paired with.
The chip emits a signal that is picked up by coils that are positioned around the barrels of ignition inside the vehicle. The coils are activated once the key is within range and send a signal of electromagnetic energy to the transponder chip. The chip responds by sending a unique identification code to the car. The unique code is used to unlock the doors and begin the engine.
Similar technology was employed in military aircraft during the World War 2 era to aid air traffic controllers in identifying them on radar. This type of chip is still in use in the aviation industry.
These systems were believed 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. However, the technology behind these chips has since been upgraded and they are no longer completely replica-proof. This has led a number of auto locksmiths to upskill their skills by learning to read and write these modern chips.
Immobilisers
The Renaults are a bit complex in the way they operate when it comes to their immobilisers as well as keys. There are two major systems that affect the way a replacement key is programmed to the car. The older one uses an "kill switch" that connects to one of the crucial car's components to enable it to disable it if the right key is not present. These are very delicate and require an experienced technician to determine and correct the issue if they fail.
The newer system is much easier to use. It uses rolling security codes and advanced cryptography to thwart copying of the code from the key or ECU. This is the method that will be used in the replacement keys we supply.
Certain models may even feature an earpiece that cannot be recognized by standard transponder scanners and is specific to the vehicle. This is extremely effective in preventing hotwiring and is also very hard to bypass using a standard key or an emulator for transponders. We have a product known as the Renault Antenna Emulator that we can use to bypass this type of immobiliser on Renault Clio phase two models as well as on some Renault commercial vehicles that are equipped with ID46 Transponders. replacement key for renault trafic van emulates the operation of a key transponder that is valid inside the ring antenna. It can be used to replace damaged or lost keys without the need to disassemble the ECU. It has been tested and endorsed by Thatcham to offer additional assurance to motor insurance customers.
