Renault has a long record of innovation. It was the first company to utilize remote central locking in production vehicles. This technology was invented by Paul Lipschultz for his employer Niemens who supply security components to the automotive industry. This innovation was a huge leap for safety in cars.
Remotes
Despite smartphones seeming to be on the verge of replacing them, the hands-free cards of Renault continue to be used widely in their vehicles. In fact, they're used in two of the three vehicles Renault sells, and their use rate has been rising in recent years. In this video, Pascaline of Renault's products division explains the main components of these cards and how they work.
Renaults come with a complicated immobiliser system, which is why it's important to understand the basics before attempting to unlock a car with a key. Certain cars come with an emergency lock fitted to the handle of the passenger door that can be used in the event that keys stop working or the battery runs out. This is a solution for those who don't want to hire a professional locksmith.
You'll require a device such as an a-slim jim or pump-up if you wish 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 to the passenger side and find an insignificant lock placed on the driver's side panel next to the door handle. This is a security feature to keep people from locking themselves inside their car or accidentally stealing a neighbour's. renault kangoo spare key is a basic but efficient security feature that will help you save time and effort when you have to swiftly get into your vehicle.
Transponders
Transponders are a common feature in modern vehicles to prevent car theft. These tiny devices, that are connected to the key fob have a chip inside and can communicate with the car once it is within the range. The chips utilize a code to identify the car and key.
The chip sends an electronic signal to a pair of coils that are fitted around the ignition barrel of 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 then responds by sending back an identification code unique to the car. The unique code is used to unlock the doors and then start the engine.
A similar technology was used in military planes during the World War 2 era to aid air traffic controllers in identifying them on radar. The aviation industry still utilizes this kind of chip message.
These systems were believed 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. The technology behind these chips was improved and they no longer have replicable. This has seen many locksmiths to upgrade their skills by learning how to read, program, and write these more modern types.
Immobilisers
The Renaults are rather complex in how they work when it comes to their immobilisers as well as keys. There are two major mechanisms that affect how keys are programmed into the car. The older system uses a "kill switch" that connects to one of the vital car's starter parts to turn it off if the correct key isn't present. These are delicate devices that require a professional to determine and repair them if they malfunction.
The latest system is simpler to use. It uses rolling security codes and advanced cryptography to prevent copying of the code from the key or ECU. This is what will be used in the replacement keys we supply.
Certain models come with an antenna ring that is unique to their vehicle and is not recognized by standard transponder scanners. This is a highly effective way to prevent hotwiring, and is also difficult to remove using the standard key or transponder emulator. We have a specialist product called the Renault Antenna Emulator (RAE) that we can use to bypass this kind of immobiliser on Renault Clio phase 2 models, as well as in some Renault commercial vehicles equipped with ID46 transponders. It replicates the operation of a genuine key transponder inside the ring antenna. It can be used to replace damaged or lost keys without removing the ECU. It is Thatcham tested and certified to provide additional assurance for motor insurance customers.
