Renault has a long track record of innovation. It was the first company to have utilized remote central locking on a production vehicle. This technology was invented by Paul Lipschultz for his employer Niemens which is a manufacturer of security components to the automotive industry. This invention was a major leap forward for car safety.
Remotes
Despite smartphones seeming to be on the verge of replacing them, Renault's hands-free cards continue to be used widely in their vehicles. They're actually included in two of every three vehicles Renault sells, and their use rate has been rising in recent years. In this video Pascaline from the Products Division of Renault explains how these cards function.
Renaults come with an immobiliser system that is quite complex. It is essential to know the basics before attempting to unlock a car without a key. Certain cars have an emergency lock that is located on the door handle for passengers that can be used in the case of a key malfunction or battery running out. This is a good choice for those who don't want to pay a locksmith.
You'll require a device such as an ultra-thin jim or pump-up if you want to remove the key fob. If you don't have these tools, you could have to use an hammer and screwdriver to remove the cylinder.
You should be able get into the passenger's door and see a tiny lock in the driver's side panel next to the handle. This is a security measure to prevent thieves from accidentally taking another vehicle or locking themselves into their own. This is a simple but effective security feature that can make life easier in the event that you need to get into your vehicle.
Transponders
Transponders are found in many modern vehicles to guard against car theft. These tiny devices are affixed to the key fob, and they contain chips that communicate with the car when it is within of. These chips utilize a number to identify the car and key.
The chip transmits an electronic signal to a pair of coils that are attached to the ignition barrel of the vehicle. These coils are activated when the key is within reach 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 is then used to unlock the doors, and to start the engine.
In World War 2, a similar technology was utilized to help air traffic control to identify military aircrafts using radar. This kind of chip messaging is still utilized today 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. The technology behind these chips was improved and they no longer have clone proof. This has led many auto locksmiths to improve their skills by learning how to read, program, and write these more modern types.
Immobilisers
The Renaults are very complicated in the way they operate with regard to keys and immobilisers. There are two major systems that affect the way keys are programmed into the car. The older system uses an "kill switch" to disable a vital component of the car's start-up mechanism if the proper key is not present. These are delicate devices that require a technician to assess and repair if they fail.
The latest system is simpler to use. It uses 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 that we supply.
Certain models may even have an extra ring antenna that can't be recognized by standard transponder scanners and is specific to the vehicle. This is extremely effective in keeping hotwiring off and is extremely difficult to disable with a standard key or a transponder emulator. We have a specialist product dubbed the Renault Antenna Emulator (RAE) that we can use to bypass this type of immobiliser found in Renault Clio phase 2 models and in some Renault commercial vehicles that are equipped with ID46 transponders. It is a replica of a key transponder that is valid within the ring antenna. It can be used to replace lost or failed keys without disassembling the ECU. It has been tested by Thatcham and endorsed to provide further security for motor insurance customers.
