Renault has a long tradition of innovation. It was the first company to have utilized remote central locking on a production vehicle. The technology was developed by Paul Lipschultz for his employer Niemens which is a manufacturer of security components to the automotive industry. This innovation was a big leap in the direction of safety for cars.
Remotes
Despite the fact that smartphones seem to be close to replacing them, Renault's hands-free cards continue to be widely used in their vehicles. In fact, two of three Renault vehicles are equipped with hands-free card. The use of them has increased in recent years. In this video, Pascaline of Renault's products division explains the most important components of these cards and how they function.
Renaults have a surprisingly complex immobiliser system, which is why it's important to be aware of the basics before you attempt to unlock a car with a key. Certain cars have an emergency lock that is located on the handle of the door for passengers that can be used in the event of a key malfunction or battery running out. This is a solution for those who don't wish to hire a locksmith professional.
You'll need a tool such as an ultra-thin jim or pump-up in order to remove the key fob. If you don't have the tools, you may need to make use of a screwdriver and hammer to take the cylinder out.
You should be able to get into the passenger door and find an insignificant lock placed on the driver's side panel close to the handle of the door. This is a safety feature to stop people from locking themselves inside their own vehicle or accidentally stealing their neighbor's. It's an easy, but effective security measure that will save you a lot of time and stress if you need to get into your vehicle quickly.
Transponders
Transponders are a common feature in modern vehicles to deter theft of cars. These tiny devices are attached to the key fob. They contain chips that communicate with the car whenever it is within the range. The chips utilize a unique code to identify the key and inform it what vehicle it is associated with.
The chip transmits the signal which is received by two coils that are placed around the ignition barrel in the vehicle. The coils are activated once the key is within reach and transmit a pulse of electromagnetic energy to the transponder chip. The chip responds by sending a unique identifier to the car. The unique code is used to unlock the doors and then start the engine.
In World War 2, a similar technology was utilized to help air traffic control to identify military aircrafts on radar. This type of chip messaging is still utilized today in the aviation industry.
These systems were thought to be clone proof up 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. However, the technology behind these chips has since been upgraded and they are now no longer completely clone-proof. This has led a number of auto locksmiths to upskill their skills by learning to read and write the more advanced chips.
Immobilisers
The Renault is a bit muddled when it comes to key systems and immobilisers. There are two main systems in use that effect the way that a replacement key is programmed to the car. The older system utilizes a "kill switch" to turn off a crucial element of the car's starting mechanism if the correct key is not present. These are delicate devices that require a professional to determine and repair if they fail.
The newer system is much easier to use. It utilizes advanced cryptography and rolling security codes to avoid copying the code from the ECU or key. This is the code that will be used to replace keys that we supply.
Some models will even use an earpiece which is not identified by standard transponder scanners, and is exclusive to the vehicle. renault car key replacement is very effective at preventing hotwiring and is also very hard to bypass using a standard keys or an emulator for transponders. We have a product known as the Renault Antenna Emulator that we can use in order to disable this type of immobiliser on Renault Clio phase two models and on some Renault commercial vehicle fitted with ID46 Transponders. It works by mimicking the operation of a valid transponder in the ring antenna and can be used for failed or lost keys without dismantling the ECU. It has been tested and approved by Thatcham to provide additional peace of mind to motor insurance customers.
