Renault has a long and rich history of innovation. It was the first company to have used remote central locking on a production car. Paul Lipschultz invented this technology for Niemens an automotive manufacturer of security components. This innovation was a huge leap in the field of car safety.
Remotes
Despite the fact that smartphones seem to be on the verge of replacing their hands-free cards, the hand-free cards from Renault are still widely used in their vehicles. In fact, two out of three Renault vehicles come with hands-free cards. Their use has increased in recent years. In this video Pascaline from Renault's Products Division explains how these cards function.
Renaults come with a complicated immobiliser system, and it's important to be aware of the basics before attempting to unlock a car with a key. Some cars have an emergency lock that is located on the passenger door handle that can be used in the event a key failure or a battery running out. This is an excellent option for those who don't wish to pay for a locksmith.

Transponders
Many modern vehicles use transponders to guard against theft of vehicles. These tiny devices are affixed to the key fob and contain an embedded chip that communicates with the car whenever it is within the range. The chips utilize a unique code to identify the key and tell it what vehicle it is associated with.
The chip transmits an electrical signal to two coils which are placed around the ignition barrel of the vehicle. The coils activate when the key is within range and send a signal 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 identify military planes on radar. The aviation industry still utilizes this type of chip code message.
Until recently they were believed to be secure against clones. 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 has been improved and they no longer have replicable. This has prompted a lot of locksmiths in the auto industry to improve their knowledge by learning how to read, write and program these newer chips.
Immobilisers
Renaults can be a bit complex when it comes to the immobilisers and key systems. There are two major systems that influence the way the new key is programmed into the car. The older system uses a "kill switch" that connects to one of the essential car starting parts in order to disable it in the event that the right key is not present. These are delicate devices that require a professional to determine and repair if they fail.
The latest system is simpler to use. It employs advanced encryption 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 feature a ring antenna that is unique to their vehicle and is not recognized by standard transponder scanners. This is an extremely effective way to prevent hotwiring, and is also difficult to remove using the standard key or transponder emulator. We have a device called the Renault Antenna Emulator that we can use in order to disable this type of immobiliser on Renault Clio phase two models and some Renault commercial vehicles with ID46 Transponders. It replicates the operation of a genuine key transponder inside the ring antenna. It can be used to replace lost or failed keys without the need to disassemble the ECU. It has been tested and endorsed by Thatcham to provide additional assurance to motor insurance customers.
