Renault has a long tradition 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 invention was a giant leap for safety in cars.
Remotes
Renault’s hands free cards are still widely used in their vehicles, despite the fact that smartphones are replacing them. In fact, two of three Renault vehicles have hands-free cards. Their use has increased in recent years. In this video Pascaline from the division of Products at Renault describes how these cards work.
Renaults have a surprisingly complex immobiliser, making it important to understand the basics prior to trying to unlock your car without keys. Some vehicles have an emergency lock attached to the handle on the door of the passenger, which is a good option if keys stop working or the battery runs out. This is a viable option for those who don’t wish to hire a locksmith professional.
You’ll require a tool such as an ultra-thin jim or pump-up in order to remove the key fob. If you don’t have these tools, it may be necessary to make use of a screwdriver and hammer to take the cylinder out.
replacement renault key will be able to step into the passenger side of the door and find an unassuming lock that is 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 effective security measure that will save you lots of time and stress in the event that you need to access your vehicle quickly.
Transponders
Transponders are installed on many modern cars to protect against theft of cars. These tiny devices are affixed to the key fob, and they contain a chip that communicates with the car whenever it is within of. The chips utilize a code to identify the car and key.
The chip emits signals that are picked up by a pair of coils fitted around the ignition barrel in the vehicle. The coils are activated once the key is within range and transmit a pulse electromagnetic energy to the transponder chip. The chip responds by sending a unique identifier to the car. The unique code will be used to unlock doors and open the car.
Similar technology was utilized in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry still uses this type of chip message.
Up until recently, these systems were considered to be invulnerable to cloning. 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 duplicate-proof. This has made many auto locksmiths to improve their skills by learning to read, write and program these newer kinds.
Immobilisers
Renaults can be a bit complex in regards to key systems and immobilisers. There are two main mechanisms that affect how keys are programmed into the car. The older one uses a “kill switch” to disable a vital part of the car’s starting mechanism if the proper key is not present. These are delicate devices that require a technician to diagnose and repair them if they malfunction.
The latest system is simpler to use. It utilizes advanced cryptography and rolling security codes to prevent copying the code from the ECU or key. This is the code that will be used to replace keys we provide.
Certain models may even feature an earpiece that isn’t identified by standard transponder scanners, and is exclusive to the vehicle. This is extremely effective in blocking hotwiring, and is extremely difficult to disable using a standard keys or a transponder emulator. We have a product known as 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 that are equipped with ID46 Transponders. It works by mimicking operation of a valid transponder in the ring antenna. It is able to be used for failed keys or lost keys without removing the ECU. It has been approved and tested by Thatcham to give peace of mind for motor insurance customers.
