Renaults use a rather complicated system as far as keys and immobilisers go. This could make the process of replacing keys extremely time-consuming. If you don't have access to your vehicle and bring it in to us to program it through the diagnostic socket it can be a lengthy.
Keys
The Renault group is perhaps best known for its manufacturing of buses, vans, Lorries and tractors but they also make cars. It is a long-standing company which was established in 1899. They offer a broad variety of car models. You'll require a new key if you are unable to locate or damage your keys to your car. Rather than waiting for your local dealer to order a replacement one for you and then wait for a longer time to receive it arrive, why don't you let us do it?

We can provide an electronic code to purchase an Renault Clio V spare key, Captur 2 spare key or New Zoe key from the dealer. We can also reset a Renault Kangoo, Traffic or Master key.
Renault has a long and rich history of innovation. It was the first company to use remote central locking in production vehicles. This technology was invented by Paul Lipschultz for his employer Niemens which is a manufacturer of security components to the automotive industry. This innovation was a huge leap in the field of car safety.
Remotes
Despite the fact that smartphones appear to be close to replacing them, Renault's hands-free cards continue to be widely used in their vehicles. In fact, they're present in the majority of vehicles Renault sells and their use rate has been rising in recent years. In this video, Pascaline of Renault's products division discusses the primary components of these cards and explains how they work.
Renaults have an immobiliser mechanism that is quite complex. It is important to understand the basics before you try to unlock a car without keys. Certain cars come with an emergency lock installed to the handle on the door of the passenger which can be used in the event that keys stop working or the batteries run out. This is a good option for those who do not want to hire a locksmith.
You'll also require access to a tool such as a pump-up key or a slim jim in order to remove the key fob and gain access. If you don't own these tools, you may require a hammer and screwdriver in order to take off the cylinder.
You should be able get to the door for the passenger and see a tiny lock inserted in the driver's side panel next to the handle. This is a security feature to keep people from locking themselves in their own vehicle or accidentally stealing a neighbour's. It's a simple, but efficient security measure that can save you lots of time and stress in the event that you need to access your vehicle quickly.
Transponders
Transponders are used on many modern cars to protect against car theft. These tiny devices are affixed to the key fob and include chips that communicate with the car when it is within the range. The chips utilize a code to identify the car and key.
The chip emits the signal which is detected by a pair of coils fitted around the ignition barrel in the vehicle. The coils are activated with the key and transmit a pulse electromagnetic energy to the chip. The chip responds by sending an identification code unique to the car. The unique code is then used to unlock the doors and begin the engine.
Similar technology was utilized in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. This type of chip code messaging is still utilized today in the aviation industry.
Up until recently they 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. However, the technology behind these chips has since been upgraded and they are now not completely replica-proof. This has led many auto locksmiths to upskill their skills by learning to read and write code for these modern chips.
Immobilisers
The Renaults are very complicated in the way they work when it comes to their immobilisers as well as keys. There are two main systems in operation that affect how a replacement keys will be programmed to the car. The older system utilizes 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 professional to determine and fix them if they fail.
The newer system is much easier to use. It makes use of advanced cryptography and rolling security codes to avoid 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 may even have an extra ring antenna that cannot be identified by standard transponder scanners, and is exclusive to the vehicle. This is an extremely effective way to prevent hotwiring, and it's also difficult to disable using a standard key or transponder emulator. We have a device called the Renault Antenna Emulator that we can use in order to bypass this immobiliser on Renault Clio phase 2 models and some Renault commercial vehicles with ID46 Transponders. It is a replica of a key transponder that is valid within the ring antenna. renault clio key card battery can be used to replace lost or failed keys without having to disassemble the ECU. It has been tested by Thatcham and approved to provide additional peace of mind for customers of motor insurance.
