Renault Keys – How They Work
Renaults use a rather complicated system as far as the immobiliser and keys go. This can result in keys replacement being a lengthy drawn out process. If you do not have access to the car and are able to bring it in for us to code through the diagnostic socket it can be a lengthy.
Keys
The Renault group is probably better known as a manufacturer of vans, buses, Lorries and tractors but they do produce cars too. It is a well-established company which was established in 1899. They offer a wide selection of cars. If you lose your keys to your car or they are damaged, you will require a replacement quickly. Why not let us buy one for you instead of waiting for your local dealer and then wait longer for it to arrive? We can replace your remote or smart key fast by calling KeyNOW.
We can provide a mechanical code for ordering an Renault Clio V spare key, Captur 2 spare key or New Zoe key from the dealer. We can also reset your Renault Kangoo Traffic or Master key.
Renault has a long tradition of innovation. It was the first company to implement remote central locking in a production vehicle. Paul Lipschultz invented this technology for Niemens the automotive manufacturer of security components. This was a significant leap in the direction of safety for cars.
Remotes
Hands-free cards from Renault are still widely used in their vehicles despite the fact smartphones appear to be replacing them. They’re actually included in two of every three vehicles Renault sells and their usage has increased in recent years. In this video, Pascaline of Renault’s products division explains the key components of these cards and how they work.
Renaults come with an immobiliser system which is quite complicated. It is essential to know the basics before attempting to unlock a vehicle without a key. Certain cars have an emergency lock that is located on the handle for the passenger door that can be used in the event a key malfunction or battery drain. This is an option for those who aren’t able to pay a professional locksmith.
You’ll also require access to a device such as an apex key or a slim jim to dismantle the key fob and gain access. 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 get to the passenger side and find an unassuming lock that is inserted into the driver’s side panel just next to the door handle. This is a safety measure to keep people from locking themselves inside their vehicle or accidentally stealing a neighbor’s. It’s a simple but effective security measure that will save you a lot of time and trouble when you have to enter your vehicle quickly.
Transponders
Transponders are used on many modern vehicles to guard against theft of cars. These small devices are fitted to the key fob and include chips that communicate with the car when it is within range. These chips use a code to identify the car and key.
The chip emits a signal that is detected by two coils positioned around the barrel of ignition in the vehicle. The coils are activated by the key and transmit a pulse electromagnetic energy to the chip. The chip responds by sending a unique code to the car. The unique code will be used to unlock doors and open the car.
During World War 2, a similar technology was used to help air traffic control to identify military aircrafts using radar. This kind of chip code messages are still used in the aviation industry.
These systems were thought to be clone proof 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. But the technology behind these chips has been upgraded and they are now no longer completely invulnerable to cloning. This has led a number of locksmiths in the auto industry to improve their knowledge by learning how to read and write code for these newer chips.
Immobilisers
Renaults are quite complex in the way they function when it comes to their keys and immobilisers. There are two main systems in use that effect the way a replacement key will be programmed to the car. The older one uses a « kill switch » to turn off a crucial part of the car’s ignition mechanism if the proper key is not present. These are delicate devices that require a professional to determine and fix if they fail.
The newer system is much simpler to use. It uses advanced encryption 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 supply.
Some models will even use an extra ring antenna that can’t be detected by the standard transponder scanners and is specific to the vehicle. This is extremely effective in blocking hotwiring, and is very difficult to get rid of by using a standard key or an emulator for transponders. We have a product known as the Renault Antenna Emulator that we can use in order to bypass this immobiliser on Renault Clio phase two models as well as on some Renault commercial vehicles that are equipped with ID46 Transponders. It mimics the operation of a transponder that is valid in the ring antenna. renault car key can be used to replace failed keys or lost keys without removing the ECU. It has been tested and approved by Thatcham in order to provide further peace of mind for motor insurance customers.
