Renault has a long tradition of innovation. It was the first company to have utilized remote central locking on a production car. This technology was invented by Paul Lipschultz for his employer Niemens, a supplier of security components to the automotive industry. This breakthrough was a huge leap forward in car safety.


The hands-free cards offered by Renault are still widely used in their vehicles despite the fact that smartphones appear to be replacing them. They’re actually included 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 explains the most important components of these cards and explains how they function.

Renaults have a surprisingly complex immobiliser system, which is why it’s important to understand the basics before you attempt to unlock a car without the use of a key. Some vehicles will have an emergency lock fitted to the passenger door handle, which can be used if the keys stop functioning or the batteries wear out. This is a great option for those who don’t wish to hire a locksmith.

You’ll also require access to a device such as a pump-up key or a slim jim to dismantle the key fob and gain access. If you don’t own these tools, you could need to use a screwdriver and hammer to take off the cylinder.

You should be able into the passenger side of the door and see the small lock inserted into the driver’s side panel just next to the door handle. This is a measure of security to stop thieves from accidentally taking other vehicles or locking themselves into their own. It’s a simple, but effective security measure that will save you lots of time and stress if you need to enter your vehicle quickly.


Many modern vehicles use transponders to stop theft of cars. These small devices, which are attached to the key fob, include a chip and can communicate with the car once it is within range. These chips utilize a number to identify the car and key.

The chip emits an electrical signal that is received by coils that are positioned around the barrel of ignition in the vehicle. These coils are activated when the key is within range and send a pulse of electromagnetic energy to the transponder chip. The chip responds by sending a unique code to the car. The unique code is used to unlock the doors and begin the engine.

Similar technology was utilized in military planes during the World War 2 era to aid air traffic controllers in identifying them on radar. The aviation industry continues to use this type of chip message.

For a long time the systems were believed to be clone-proof. 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 has been improved and they no longer have clone proof. This has prompted many auto locksmiths to upskill their knowledge by learning how to read and write code for these newer types of chips.


The Renault isn’t the most straightforward when it comes to the key systems and immobilisers. There are two main mechanisms that affect how a new key is programmed into the car. The older system uses an “kill switch” to turn off a crucial component of the car’s start-up mechanism if the correct key is not present. These are delicate devices that require a technician to assess and repair if they fail.

The newer system is more user-friendly to use. It uses rolling security codes and advanced cryptography to defeat copying of the code from the key or ECU. This is the method that will be used on the replacement keys that we supply.

Certain models have an antenna ring that is specific to the vehicle and isn’t recognized by standard transponder scanners. This is extremely effective in keeping hotwiring off and is extremely difficult to disable with a standard key or an emulator for transponders. We have a specific product called the Renault Antenna Emulator (RAE) that we can use to bypass this kind of immobiliser in Renault Clio phase 2 models and in some Renault commercial vehicles fitted with ID46 transponders. It works by mimicking operation of a functioning transponder inside the ring antenna and can be used on failed or lost keys without dismantling the ECU. It has been approved and tested by Thatcham in order to provide further security to motor insurance customers.
