Renault has a long record of innovation. It was the company that utilized remote central locking on a production car. Paul Lipschultz invented this technology for Niemens which is an automotive supplier of security components. This was a significant leap forward for car safety.
Remotes
Despite smartphones seeming to be close to 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 usage has also increased in recent years. In this video, Pascaline of Renault’s products division explains the main components of these cards and explains how they function.
Renaults have an immobiliser feature which is quite complicated. It is crucial to know the basics before attempting to unlock a car without a key. Some vehicles have an emergency lock installed to the passenger door handle and can be used if the keys stop working or the battery runs out. This is an option for those who don’t wish to pay a professional locksmith.
You’ll also need to have access to a tool such as a pump-up key or slim jim in order to dismantle the key fob and gain entry. If you do not have these tools, it might be necessary to make use of a screwdriver and hammer to take the cylinder out.
You should be able to go into the passenger’s compartment and see a tiny lock in the driver’s side panel next to the handle. This is a security measure to keep people from locking themselves in their own vehicle or accidentally stealing a neighbor’s. This is a simple, but effective security feature that can make life easier when you need to quickly get into your vehicle.
Transponders
Transponders are installed on many modern cars to protect against car theft. These small devices are connected to the key fob. They contain an electronic chip that communicates with the car when it is within range. These chips use a code to identify the car and key.
The chip transmits an electrical signal that is picked up by coils that are positioned around the barrels of ignition inside the vehicle. The coils are activated when the key is within range and transmit a pulse electromagnetic energy to the transponder chip. The chip then responds by sending a unique identification code to the car. The unique code can then be used to unlock doors or start the car.
In World War 2, a similar technology was utilized to help air traffic control officials identify military aircrafts on radar. This type of chip code 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 been improved and they are now no longer completely invulnerable to cloning. This has led to many locksmiths in the auto industry to upgrade their skills by learning to read, program and write these newer kinds.
Immobilisers
The Renault isn’t the most straightforward when it comes to immobilisers and key systems. There are two systems in operation that affect the way that a replacement key is programmed to the car. The older system uses an “kill switch” to disable a vital part of the car’s ignition mechanism if the correct key is not present. replacement renault key are extremely delicate and will need a skilled technician to determine and correct the issue if they fail.
The newer system is more user-friendly to use. It employs advanced cryptography and rolling security codes to avoid copying the code from the ECU or key. This is what will be used in the replacement keys that we supply.
Some models will even use a special ring antenna that cannot be detected by the standard transponder scanners. It is also unique to the vehicle. This is a great way to prevent hotwiring, and it’s also difficult to disable using a standard key or transponder emulator. We have a specialist product called the Renault Antenna Emulator (RAE) that can be used to bypass this type of immobiliser found in Renault Clio phase 2 models and in some Renault commercial vehicles fitted with ID46 transponders. It emulates the operation of a key transponder that is valid within the ring antenna. It can be used to replace lost or failed keys without having to disassemble the ECU. It is Thatcham tested and approved to offer additional assurance for customers of motor insurance.
