Renault has a long history of innovation. It was the company that used remote central locking on a production vehicle. Paul Lipschultz invented this technology for Niemens an automotive manufacturer of security components. This innovation was a huge leap for car safety.
Hands-free cards from Renault are still used extensively in their vehicles, despite the fact that smartphones appear to be replacing them. In fact, they’re present in two of every three vehicles Renault sells, and their usage has increased in recent years. In this video Pascaline from Renault’s Products Division describes how these cards work.
Renaults come with a complicated immobiliser, making it crucial to know the basics before you attempt to unlock your car without keys. Some vehicles have an emergency lock that is located on the handle for the passenger door that can be used in the event a key failure or a battery runout. This is a viable option for those who aren’t able to hire a professional locksmith.
You’ll require a device such as an a-slim jim or pump-up in order to remove the key fob. If you don’t have these tools, you may need to employ a screwdriver and hammer to remove the cylinder.
You should be able to walk through the passenger door and see a small lock inserted into the driver’s side panel near the door handle. This is a safety measure to ensure that people don’t lock themselves inside their vehicle or stealing the neighbour’s. It’s a simple, but effective security measure that can save you lots of time and stress when you have to access your vehicle quickly.
Transponders are used on many modern cars to help protect against theft of cars. These tiny devices, that are connected to the key fob, include a chip and can communicate with the car once it is within range. The chips utilize a unique code to identify the key and inform it which vehicle it is linked with.
The chip transmits a signal that is detected by two coils positioned around the ignition barrel inside the vehicle. The coils are activated with the key and transmit an electromagnetic pulse to the chip. The chip responds by sending a unique identification to the car. The unique code is used to unlock the doors, and to start the engine.
Similar technology was employed in military aircraft during the World War 2 era to help air traffic controllers identify them on radar. The aviation industry still uses this type of chip message.
These systems were thought to be clone proof up 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. However, renault key card replacement near me behind these chips has since been upgraded and they are now not completely replica-proof. This has led many auto locksmiths to upgrade their knowledge by learning how to read and write the newer types of chips.
The Renault is a bit muddled when it comes to key systems and immobilisers. There are two main methods in use that affect the way a replacement key will be programmed into the car. The older system utilizes an “kill switch” that connects to one of the vital car starting parts in order to turn it off if the right key is not present. These are very delicate and will need a trained technician to correctly diagnose and rectify if they fail.
The newer system is easier to use. It utilizes rolling security code and advanced cryptography to prevent copying of the code from the key or ECU. This is the code that will be used to replace keys we supply.
Some models use an earpiece antenna that is specific to their vehicle and is not recognized by transponder scanners that are standard. This is very effective at blocking hotwiring, and is very difficult to get rid of by using a standard key or an emulator for transponders. We have a specific product dubbed the Renault Antenna Emulator (RAE) that we can use to bypass this type of immobiliser in Renault Clio phase 2 models as well as some Renault commercial vehicles that are equipped with ID46 transponders. It mimics the operation of a valid transponder in the ring antenna and can be used on damaged keys that are lost or stolen without dismantling the ECU. It is tested and approved by Thatcham to provide additional peace of mind for motor insurance customers.
