Renault Keys - How They Work

Renaults have a complex system for immobilisers as well as keys. This makes the process of replacing keys very time-consuming. It could take a lengthy time to program the car, unless you have access to it and can bring it to us.

Keys

The Renault group is perhaps better known as a manufacturer of buses, vans Lorries and tractors however they also make cars. Established in 1899 it is a large and well-established business with an array of cars. You will need a new key if you are unable to locate or damage your car keys. Why not let us make one for you instead of waiting for your local dealer to do so and then waiting for it to arrive? We can replace your smart key or remote fast by calling KeyNOW.

If you need a Renault Clio V, Captur 2 or New Zoe spare key we can provide you with a mechanical code to order a new key from the dealer. We can also reset the Renault Kangoo, Traffic or Master key.





Renault has a long record of innovation. It was the first company to use remote central locking in a production vehicle. Paul Lipschultz invented this technology for Niemens the automotive manufacturer of security components. This breakthrough was a massive leap for car safety.

Remotes

Hands-free cards from Renault are still used extensively in their vehicles despite the fact smartphones are replacing them. In fact, they're used in two of the three vehicles Renault sells, and their use rate has been rising in recent years. In this video, Pascaline of Renault's products division explains the key components of these cards and how they function.

Renaults have a fairly complicated immobiliser system, which is why it's crucial to know the basics before trying to unlock your car without a key. Some vehicles have an emergency lock installed to the passenger door handle that can be used in the event that keys stop working or the battery runs out. This is a good option for people who don't want to pay for a locksmith.

You'll also need to have access to a tool such as a pump-up key or slim jim to remove the key fob and gain access. If you don't have these tools, you could have to use an hammer and screwdriver to remove the cylinder.

renault clio key should be able into the passenger door and you will see an unassuming lock that is inserted into the side panel of the driver near the door handle. This is a precautionary measure to prevent thieves from accidentally taking other vehicles or locking themselves to 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 car.

Transponders

Transponders are installed on many modern vehicles to guard against car theft. These tiny devices, that are connected to the key fob, have a chip inside and can communicate with the car once it is within range. These chips use a code to identify the car and key.

The chip transmits signals that are received by two coils that are placed around the ignition barrel in the vehicle. These coils are activated by the key and send an electromagnetic pulse to the chip. The chip then responds by sending a unique identification code to the car. The unique code is then used to unlock the doors and then start the engine.

A similar technology was used in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry is still using this kind of chip message.

Up until recently they were believed to be secure against clones. 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 clone proof. This has prompted a lot of locksmiths in the auto industry to improve their knowledge by learning how to read and write code for these newer chips.

Immobilisers

Renaults can be a bit complex when it comes to key systems and immobilisers. There are two major systems that affect the way a new key is programmed into the car. The older one uses a "kill switch" to disable a vital element of the car's starting mechanism if the proper key is not present. These are delicate devices that require a technician to diagnose and repair them if they malfunction.

The latest system is simpler to use. It employs rolling security codes and advanced cryptography to thwart copying of the code from the key or ECU. This is the code that will be used to replace keys we supply.

Certain models have rings that are specific to their vehicle and cannot be detected by transponder scanners that are standard. This is very effective at blocking hotwiring, and is extremely difficult to disable using a standard key or a transponder emulator. We have a device called the Renault Antenna Emulator that we can use in order to bypass this type immobiliser on Renault Clio phase two models and some Renault commercial vehicles that are equipped with ID46 Transponders. It emulates the operation of a functioning key transponder within the ring antenna. It can be used to replace lost or failed keys without the need to disassemble the ECU. It has been tested and endorsed by Thatcham to give peace of mind for motor insurance customers.
