Renault Keys - How They Work
Renaults utilize a very complicated system in terms of keys and immobilisers are concerned. This could make the process of changing keys a lengthy process. It could take a lengthy time to code the car if you have access to it and bring it to us.
Keys
The Renault group is perhaps best known for its production of buses, vans, Lorries and tractors but they also make cars. Established in 1899 it is a large and well established company with an array of automobile models. If you lose your keys to your car or have them damaged, you'll require a replacement quickly. Why not let us make one for you instead of waiting for your local dealer to order one and then waiting for it to arrive? We can replace your remote or smart key with ease by calling KeyNOW.
We can provide a mechanical code for ordering an Renault Clio V spare key, Captur 2 spare key or New Zoe key from the dealer. We can also reset a Renault Kangoo, Traffic or Master key.
Renault has a long and rich history of innovation. It was the first company to utilize remote central locking in a production vehicle. Paul Lipschultz invented this technology for Niemens the automotive manufacturer of security components. This invention was a giant leap for car safety.
Remotes
Despite smartphones seeming to be on the verge of replacing their hands-free cards, the hand-free cards from Renault continue to be used widely in their vehicles. In fact, two out of three Renault vehicles are equipped with hands-free card. 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 system that is a bit complicated. It's important to know the basics before trying to unlock your car without a key. Certain cars have an emergency lock on the handle of the door for passengers that can be used in the event of an unreliable key or battery drain. This is an excellent option for those who do not want to pay a locksmith.
You'll also need to have access to tools such as a pump-up key or a slim jim to remove the key fob and gain entry. If you don't have these tools, you could have to use a screwdriver and hammer to remove the key fob.
You should be able into the passenger side of the door and you will see an unassuming lock that is inserted into the driver's side panel near the door handle. This is a safety measure to prevent individuals from accidentally stealing other vehicles or locking themselves inside their own. It's a simple but efficient security feature that will save you time and stress when you need to quickly get into your vehicle.
Transponders
Many modern vehicles use transponders to deter theft of cars. These tiny devices are attached to the key fob and contain an embedded chip that communicates with the car when it is within of. These chips utilize a number to identify the car and key.
renault trafic key fob transmits an electrical signal to two coils which are placed around the ignition barrel of the vehicle. The coils are activated when you turn the key and send an electromagnetic pulse to the chip. The chip responds by sending a unique identifier to the car. The unique code is used to unlock the doors and start 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. The aviation industry still uses this type of chip code message.
These systems were believed 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. The technology behind these chips was enhanced, and they no longer have clone proof. This has led to many auto locksmiths upgrade their skills by learning to read, program and write these newer kinds.
Immobilisers
Renaults can be a bit complex when it comes to the key systems and immobilisers. There are two systems in use that effect the way a replacement key is programmed to the car. The older one uses a "kill switch" that connects to one of the essential car's components to enable it to disable it in the event that the correct key isn't present. These are very delicate and will need a skilled technician to determine and correct the issue if they fail.
The latest system is simpler to use. It makes use of advanced cryptography and rolling security codes to avoid copying the code from the ECU or key. This is the code that will be used to replace keys that we supply.
Certain models have rings that are specific to the vehicle and isn't detected by standard transponder scanners. This is very effective at keeping hotwiring off and is extremely difficult to disable with a standard key or a transponder emulator. We have a special product dubbed the Renault Antenna Emulator (RAE) that can be used to bypass this kind of immobiliser on Renault Clio phase 2 models and in some Renault commercial vehicles fitted with ID46 transponders. It mimics the operation of a transponder that is valid in the ring antenna and can be used to replace failed or lost keys without dismantling the ECU. It has been approved and tested by Thatcham to offer additional security to motor insurance customers.
