Renault has a long track record of innovation. It was the first company to have utilized remote central locking on a production car. Paul Lipschultz invented this technology for Niemens the automotive manufacturer of security components. This innovation was a huge leap for the safety of cars.
Remotes
Despite the fact that smartphones appear to be on the verge of 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. Their usage has also increased in recent years. In this video Pascaline from the division of Products at Renault explains the way these cards work.
Renaults come with a complicated immobiliser system, which is why it’s important to understand the basics prior to trying to unlock your car without keys. Some vehicles have an emergency lock on the passenger door handle that can be utilized in the event of the key not working or a battery drain. This is a good choice for people who don’t want to pay for a locksmith.
You’ll require a device such as the slim jim or pump-up if you want to remove the key fob. If you don’t have the tools, you may need to make use of a screwdriver and hammer to take the cylinder out.
You should be able to walk into the passenger side of the door and you will see an insignificant lock placed on the driver’s side panel near the door handle. This is a security feature to stop people from locking themselves in their own vehicle or accidentally stealing their neighbor’s. This is a simple but effective security feature that can help you save time and effort when you need to quickly get into your car.
Transponders
Transponders are found in many modern cars to help protect against car theft. These small devices, which are connected to the fob of the key, contain a chip and communicate with the car once it is within the range. The chips utilize a code to identify the car and key.
The chip sends a signal to a pair coils which are placed around the ignition barrel of the vehicle. These coils are activated when the key is within range and transmit a pulse of electromagnetic energy to the transponder chip. The chip responds by sending a unique code to the car. The unique code can be used to unlock doors and 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 messages are still used 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. But the technology behind these chips has since been upgraded and they are now no longer completely clone-proof. This has led to many locksmiths in the auto industry to upgrade their skills by learning to read, program and write these newer types.
Immobilisers
The Renaults are a bit complex in the way they operate when it comes to their immobilisers and keys. There are two main systems in operation that affect how a replacement keys will be programmed into the car. The older system utilizes a “kill switch” to disable a vital component of the car’s start-up mechanism if the correct key is not present. They are extremely delicate and will need a trained technician to correctly diagnose and rectify if they fail.
The newer system is much easier to use. It utilizes advanced encryption and rolling security codes to avoid copying the code from the ECU or key. This is the method that will be used in the replacement keys that we provide.
Certain models come with an antenna ring that is unique to their vehicle and cannot be detected by standard transponder scanners. This is an extremely effective way to prevent hotwiring, and is also difficult to disable using an ordinary key or transponder emulator. We have a device called the Renault Antenna Emulator that we can use to bypass this immobiliser on Renault Clio phase 2 models and on some Renault commercial vehicle fitted with ID46 Transponders. It emulates the operation of a key transponder that is valid within the ring antenna. It can be used to replace damaged or lost keys without removing the ECU. It is Thatcham tested and approved to provide additional assurance for customers of motor insurance.
