Many modern cars use transponders to deter theft of cars. These small devices, which are attached to the key fob have a chip inside and can communicate with the car when it is within of. These chips utilize a number to identify the car and key.

The chip transmits an electrical signal that is picked up by two coils positioned around the ignition barrel inside the vehicle. The coils are activated when the key is within reach and send a signal of electromagnetic energy to the transponder chip. The chip responds by sending a unique identification code to the car. The unique code is used to unlock the doors and begin the engine.

Similar technology was employed in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. This kind of chip code messages are still used in the aviation industry.

These systems were thought 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.

key card for renault megane replacement can be a bit complex in regards to immobilisers and key systems. There are two major methods in use that affect the method by which a replacement key will be programmed into the car. The older system utilizes an “kill switch” that connects to one of the important car’s components to enable it to disable it if the correct key isn’t present. These are delicate devices that require a professional to determine and fix if they fail.

The latest system is easier to use. It employs 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 rings that are specific to their vehicle and cannot be detected by standard transponder scanners. This is a great method to avoid hotwiring and it’s also difficult to disable using the standard key or transponder emulator. We have a product known as the Renault Antenna Emulator that we can use in order to bypass this immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles that are equipped with ID46 Transponders. It works by mimicking operation of a valid transponder in the ring antenna and can be used for failed keys, or lost keys, without having to dismantle the ECU. It is Thatcham tested and certified to provide additional security for motor insurance customers.
