Renault has a long tradition of innovation. It was the first company to have used remote central locking on a production car. The technology was developed by Paul Lipschultz for his employer Niemens who supply security components to the automotive industry. This innovation was a huge leap for the safety of cars.
Remotes
Renault's hands free cards are still used extensively in their vehicles, despite the fact that smartphones appear to be replacing them. In fact, they're included in two of every three vehicles Renault sells and their usage rate has been rising in recent years. In this video Pascaline from the Product Division of Renault explains the way these cards work.
Renaults have an immobiliser system that is quite complex. It's important to know the basics before you try to unlock a car without the use of a key. Some vehicles have an emergency lock on the passenger door handle that can be used in the event of a key failure or a battery drain. This is an option for those who aren't able to hire a professional locksmith.
You'll also require access to a device such as the pump-up key or slim jim to take the key fob off and gain entry. If you don't have these tools it may be necessary to use a hammer and screwdriver to remove the cylinder.
You should be able get into the passenger's side and see a tiny lock in the driver's compartment next to the handle. This is a security measure to prevent thieves from accidentally taking another vehicle or locking themselves in their own. This is a basic but efficient security feature that will save you time and hassle in the event that you need to get into your vehicle.
Transponders
Transponders are found in many modern vehicles to guard against theft of cars. These small devices are connected to the key fob, and they contain an embedded chip that communicates with the car whenever it is within range. These chips use a distinct code to identify the key and then tell it what vehicle it is associated with.
The chip sends a signal to a pair coils that are positioned around the ignition barrel of the vehicle. The coils are activated when you turn the key and send a pulse electromagnetic energy to the chip. The chip then responds by sending an unique identification code to the car. The unique code can then be used to unlock doors and open the car.
Similar technology was employed in military aircraft during the World War 2 era to aid air traffic controllers in identifying them on radar. The aviation industry continues to use this type of chip message.
Until recently, these systems were considered to be clone-proof. 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 are no longer replicable. This has led a number of locksmiths in the auto industry to improve their knowledge by learning how to read and write these newer types of chips.
Immobilisers
Renaults can be a bit complex when it comes to immobilisers and key systems. There are two major systems that affect the way keys are programmed into the car. The older system uses an "kill switch" to turn off a crucial element of the car's starting mechanism if the proper key is not present. These are extremely delicate and will need a skilled technician to diagnose and rectify if they fail.
The newer system is much easier to use. It employs advanced cryptography and rolling security codes to prevent copying the code from the ECU or key. This is the method that will be used on the replacement keys that we provide.
Certain models have an earpiece antenna that is unique to their vehicle and cannot be detected by transponder scanners that are standard. This is a highly effective method to avoid hotwiring and it's also difficult to remove using the standard key or transponder emulator. We have a product called the Renault Antenna Emulator that we can use in order to bypass this type immobiliser on Renault Clio phase 2 models as well as some Renault commercial vehicles that are equipped with ID46 Transponders. It works by mimicking the operation of a valid transponder within the ring antenna. It can be used for failed keys or lost keys without removing the ECU. It is tested and approved by Thatcham in order to provide further peace of mind for motor insurance customers.
