Renault has a long history of innovation. It was the company that used remote central locking on a production vehicle. The technology was developed by Paul Lipschultz for his employer Niemens who supply security components to the automotive industry. This was a significant leap in the direction of safety for cars.
Remotes
The hands-free cards offered by Renault are still used extensively in their vehicles despite the fact smartphones appear to be replacing them. In fact, they’re included in two out of three vehicles Renault sells, and their use has increased in recent years. In this video Pascaline from the Products Division of Renault explains the way these cards work.
Renaults have an immobiliser system that is a bit complicated. It’s important to know the basics before attempting to unlock your vehicle without keys. Certain cars have an emergency lock on the passenger door handle that can be utilized in the event of a key failure or a battery runout. This is a good choice for those who don’t want to pay for a locksmith.
You’ll require a tool such as the slim jim or pump-up in order to remove the key fob. If you don’t have these tools it might be necessary to use a hammer and screwdriver to remove the cylinder.
You should be able to go into the passenger’s door and you will see a tiny lock inserted in the driver’s panel, next to the handle. This is a precautionary measure to stop thieves from accidentally taking other vehicles or locking themselves inside their own. It’s a simple but effective security feature that can save you time and hassle when you need to quickly get into your car.
Transponders
Transponders are found in many modern cars to safeguard against theft of cars. These small devices, that are attached to the key fob, have a chip inside and can communicate with the car once it is within range. These chips employ a code to identify the car and key.
The chip emits the signal which is detected by coils that are positioned around the ignition barrel in the vehicle. The coils are activated when the key is within reach and send a pulse of electromagnetic energy to the transponder chip. The chip then responds by sending back a unique identification code to the car. The unique code is used to unlock the doors, and to start the engine.
In World War 2, a similar technology was used to help air traffic control detect military planes on radar. The aviation industry is still using this type of chip message.
Up until recently the systems were believed to be invulnerable to cloning. 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 enhanced, and they are no longer replicable. This has led many auto locksmiths upgrade their skills by learning to read, program, and write these more modern types.
Immobilisers
Renaults are quite complicated in the way they work when it comes to keys and immobilisers. There are two major systems that affect how a replacement keys is programmed to the car. The older one uses a “kill switch” to turn off a crucial component of the car’s start-up mechanism if the proper key is not present. These are delicate devices that require a specialist to identify and fix if they fail.
renault key card replacement cost is simpler to use. It makes use of 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 we supply.
Certain models come with rings that are specific to their vehicle and isn’t detected by transponder scanners that are standard. This is a highly effective way to prevent hotwiring, and it is also very difficult to bypass with an ordinary key or transponder emulator. We have a specialized product called the Renault Antenna Emulator (RAE) that can be used to disable this kind of immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles equipped with ID46 transponders. It works by mimicking operation of a valid transponder within the ring antenna and can be used on damaged keys, or lost keys, without having to dismantle the ECU. It has been tested and approved by Thatcham in order to provide further peace of mind for motor insurance customers.
