Paul Lipschultz invented this technology for Niemens which is an automotive supplier of security components. This innovation was a huge leap for the safety of cars.


Renault’s hands free cards are still widely used in their vehicles, despite the fact that smartphones appear to be replacing them. In fact, two out of three Renault vehicles come with hands-free cards. Their usage has also increased in recent years. In this video, Pascaline of Renault’s products division explains the main components of these cards and explains how they function.

Renaults have an immobiliser system that is quite complicated. It’s important to know the basics before trying to unlock a vehicle without a key. Some cars will have an emergency lock installed to the handle on the door of the passenger which is a good option if keys stop working or the batteries run out. This is a good choice for those who don’t wish to hire a locksmith.

You’ll require a device such as a slim jim or a pump-up if you wish 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 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 safety measure to stop thieves from accidentally taking the vehicle of another or locking themselves inside their own. This is a simple, but efficient security feature that will save you time and stress in the event that you need to get into your vehicle.


Many modern cars use transponders to guard against theft of vehicles. These tiny devices, that are connected to the fob of the key, contain a chip that communicates with the car once it is within range. These chips employ a code to identify the car and key.

The chip emits an electrical signal that is detected by a pair of coils fitted around the barrel of ignition in the vehicle. The coils are activated with the key and transmit a pulse electromagnetic energy to the chip. The chip responds by sending back an unique identification code to the car. The unique code can be used to unlock doors and start the car.

During World War 2, a similar technology was employed to assist air traffic control officials identify military planes on radar. This kind of chip messages are still used in the aviation industry.

For a long time 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 has been improved and they are no longer replicable. This has made many locksmiths in the auto industry to upgrade their skills by learning to read, program, and write these more modern kinds.


The Renault isn’t the most straightforward when it comes to the key systems and immobilisers. There are two broad systems in operation that affect the way that a replacement key will be programmed to the car. The older one uses the “kill switch” that connects to one of the crucial car starting parts in order to disable it in the event that the right key is not present. They are extremely delicate and will need a skilled technician to detect and fix the issue should they fail.

The newer system is easier to use. It utilizes advanced cryptography and rolling security codes to prevent copying the code from the ECU or key. This is the code that will be used to replace keys we supply.

Certain models come with a ring antenna that is specific to the vehicle and cannot be recognized by transponder scanners that are standard. This is an extremely effective way to prevent hotwiring, and is also difficult to disable using an ordinary key or transponder emulator. We have a specific product dubbed the Renault Antenna Emulator (RAE) that can be used to circumvent this kind of immobiliser in Renault Clio phase 2 models and 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 is Thatcham tested and approved to offer additional assurance for customers of motor insurance.
