This technology was invented by Paul Lipschultz for his employer Niemens who supply security components to the automotive industry. This breakthrough was a huge leap forward in car safety.
Remotes
Despite the fact that smartphones appear to be on the verge of replacing them, Renault's hands-free cards continue to be widely used in their vehicles. In fact, they're present in two out of three vehicles Renault sells and their usage has increased in recent years. In this video, Pascaline of Renault's products division explains the key components of these cards and explains how they work.
Renaults have an immobiliser system that is quite complex. It is crucial to know the basics prior to trying to unlock a vehicle without keys. Some vehicles have an emergency lock that is located on the handle for the passenger door that can be used in the event the key not working or a battery running out. This is a solution for those who don't want to pay a professional locksmith.
You'll require a device such as a slim jim or a pump-up in order to remove the key fob. If you don't have these tools, it might be necessary to make use of a screwdriver and hammer to take the cylinder out.

Transponders
Many modern cars use transponders to stop theft of cars. These tiny devices are affixed to the key fob. They contain an electronic chip that communicates with the car when it is within of. The chips utilize a unique code to identify the key and then tell it what vehicle it is associated with.
The chip emits the signal which is detected by a pair of coils fitted around the ignition barrel in the vehicle. The coils are activated by the key and send a pulse electromagnetic energy to the chip. The chip then responds by sending an unique identification code to the car. The unique code can be used to unlock doors and begin the car.
A similar technology was used in military planes during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry still utilizes this kind of chip message.
For a long time the systems were believed to be clone-proof. 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 not completely clone-proof. replacement renault megane key card has led many auto locksmiths to upskill their skills by learning to read and write the newer types of chips.
Immobilisers
The Renaults are very complicated in the way that they operate with regard to their keys and immobilisers. There are two main mechanisms that affect how the new key is programmed into the car. The older system uses a "kill switch" that connects to one of the important car's starting components in order to disable it if the correct key isn't present. They are very delicate and will need a skilled technician to determine and correct the issue if they fail.
The newer system is easier to use. It uses advanced cryptography and rolling security codes to prevent copying the code from the ECU or key. This is the method that will be used on the replacement keys we provide.
Some models will even use an earpiece that cannot be recognized by standard transponder scanners and is specific to the vehicle. This is extremely effective in blocking hotwiring, and is very difficult to get rid of using a standard key or a transponder emulator. We have a special product dubbed the Renault Antenna Emulator (RAE) that can be used to circumvent this type of immobiliser found in Renault Clio phase 2 models, as well as in some Renault commercial vehicles equipped with ID46 transponders. It is a replica of a valid key transponder within the ring antenna. It can be used to replace lost or failed keys without removing the ECU. It has been tested by Thatcham and endorsed to provide further peace of mind for customers of motor insurance.
