Renault Keys – How They Work

Renaults have a sophisticated system of immobilisers and keys. This can lead to replacement keys being a lengthy drawn out process. If you don’t have access to the car and can bring it in for us to program it through the diagnostic socket, it can be very time-consuming.

Keys

The Renault group is perhaps best known as a manufacturer of vans, buses, tractors and Lorries although they do produce cars too. Established in 1899 it is a large and well-established company that offers an extensive selection of car models.

Renault has a long record of innovation. It was the first company to implement remote central locking in production vehicles. Paul Lipschultz invented this technology for Niemens which is an automotive supplier of security components. This was a major leap for safety in cars.

Remotes

Despite the fact that smartphones are on the verge of replacing their hands-free cards, the hand-free cards from Renault are still widely used in their vehicles. They’re actually included in the majority of vehicles Renault sells and their use has increased in recent years. In this video, Pascaline of Renault’s products division discusses the primary components of these cards and explains how they work.

Renaults have a surprisingly complex immobiliser system, which is why it’s crucial to know the basics before trying to unlock a car without a key. Some vehicles have an emergency lock that is attached to the passenger door handle, which can be used if the keys stop working or the battery runs out. This is a viable option for those who aren’t able to hire a locksmith professional.

You’ll need a tool, such as an a-slim jim or pump-up in order to remove the key fob. If you don’t have these tools, you could require an hammer and screwdriver to take off the key fob.

You should be able through the passenger door and see a small lock inserted into the driver’s side panel next to the door handle. This is a safety feature to keep people from locking themselves inside their vehicle or accidentally stealing a neighbor’s. It’s a simple but efficient security measure that can help you save time and hassle when you have to access your vehicle quickly.

Transponders

Many modern vehicles use transponders to prevent car theft. These tiny devices are affixed to the key fob, and they contain an embedded chip that communicates with the car when it is within the range. The chips utilize a unique code to identify the key and tell it which vehicle it is paired with.

renault captur key card replacement transmits an electronic signal to a pair of coils which are placed around the ignition barrel of the vehicle. The coils are activated with the key and transmit a pulse electromagnetic energy to the chip. The chip responds by sending a unique code to the car. The unique code can be used to unlock doors or start the car.

A similar technology was used in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. This kind of chip messaging is still utilized today in the aviation industry.

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 upgraded, and they no longer have clone proof. This has prompted a lot of auto locksmiths to upgrade their skills by learning to read and write these modern chips.

Immobilisers

Renaults can be a bit complex when it comes to key systems and immobilisers. There are two major systems that affect the way the new key is programmed into the car. The older system utilizes an “kill switch” that connects to one of the vital car’s components to enable it to turn it off if the right key is not present. These are delicate devices that require a technician to diagnose and fix them if they fail.

The newer system is much easier to use. It makes use of advanced cryptography and rolling security codes to avoid copying the code from the ECU or key. This is what will be used in the replacement keys that we provide.

Certain models come with rings that are specific to the vehicle and isn’t detected by transponder scanners that are standard. This is a very effective way to prevent hotwiring, and it is also very difficult to bypass using a standard key or 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 some Renault commercial vehicles fitted with ID46 transponders. It emulates 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 is Thatcham tested and approved to offer additional assurance for customers of motor insurance.
