Renault has a long history 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, a supplier of security components to the automotive industry. This breakthrough was a massive leap in the field of car safety.
Remotes
Hands-free cards from Renault are still widely used in their vehicles, despite the fact that smartphones are replacing them. In fact, two of three Renault vehicles are equipped with hands-free card. Their use has increased in recent years. In this video Pascaline from the Products Division of Renault explains the way these cards work.
Renaults come with a complicated immobiliser, making it crucial to know the basics before attempting to unlock a car with keys. Some vehicles have an emergency lock on the handle for the passenger door that can be utilized in the event of a key failure or a battery runout. This is a viable option for those who don't wish to pay a professional locksmith.
You'll also need to have access to a device such as the pump-up key or slim jim in order to take the key fob off and gain entry. If you do not have these tools, it could be necessary to make use of a screwdriver and hammer to take the cylinder out.
You should be able get into the passenger's side and you will see a tiny lock inside the driver's panel, next to the handle.

Transponders
A lot of modern cars have transponders to prevent car theft. These small devices are fitted to the key fob and include a chip that communicates with the car whenever it is within range. The chips utilize a unique code to identify the key and tell it which vehicle it is paired with.
The chip transmits an electrical signal that is detected by two coils positioned around the ignition barrel inside the vehicle. The coils are activated when you turn the key and transmit an electromagnetic pulse to the chip. The chip responds by sending a unique identifier to the car. The unique code is then used to unlock the doors and begin the engine.
Similar technology was also used in military planes during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry is still using this type of chip message.
For a long time 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 was upgraded, and they no longer have clone proof. This has led to many auto locksmiths upgrade their skills by learning to read, program, and write these more modern types.
Immobilisers
The Renault isn't the most straightforward in the area of key systems and immobilisers. There are two major mechanisms that affect how the new key is programmed into the car. The older system employs a "kill switch" to turn off a crucial part of the car's ignition mechanism if the proper key is not present. They are extremely delicate and will need a trained technician to correctly determine and correct the issue if they fail.
The latest system is simpler to use. It makes use of advanced encryption and rolling security codes to prevent copying the code from the ECU or key. This is what will be used in the replacement keys that we supply.
Certain models may even have a special ring antenna that can't be detected by the standard transponder scanners. It is also unique to the vehicle. This is extremely effective in blocking hotwiring, and is very hard to bypass with a standard key or a transponder emulator. We have a product called the Renault Antenna Emulator that we can use in order to bypass this immobiliser on Renault Clio phase 2 models as well as some Renault commercial vehicle fitted with ID46 Transponders. It emulates the operation of a valid key transponder within the ring antenna. It can be used to replace damaged or lost keys without disassembling the ECU. It has been tested and endorsed by Thatcham to offer additional peace of mind for motor insurance customers.
