Renault has a rich history of innovation. It was the company that utilized remote central locking on a production car. The technology was developed by Paul Lipschultz for his employer Niemens who supply security components to the automotive industry. This breakthrough was a massive leap in the field of car safety.
Remotes
Despite the fact that smartphones appear to be close to replacing their hands-free cards, the hand-free cards from Renault are still used extensively in their vehicles. In fact, two out of three Renault vehicles are equipped with hands-free cards. The use of them has increased in recent years. In this video Pascaline from the division of Products at Renault explains the way these cards work.
Renaults have a surprisingly complex immobiliser system, and it's crucial to know the basics before trying to unlock a car without keys. renault car key replacement have an emergency lock fitted to the door handle of the passenger, which can be used if the keys stop functioning or the batteries wear out. This is an excellent option for people who don't want to pay for a locksmith.
You'll need a tool such as an a-slim jim or pump-up if you want to remove the key fob. If you don't own these tools, you may require the screwdriver and hammer to remove the key fob.
You should be able to walk into the passenger's compartment and find a small lock in the driver's compartment next to the handle.

Transponders
Transponders are used on many modern cars to safeguard against theft of cars. These tiny devices are attached to the key fob and include chips that communicate with the car when it is within range. The chips utilize a code to identify the car and key.
The chip transmits an electrical signal that is detected by two coils positioned around the barrels of ignition inside the vehicle. The coils are activated once the key is within range and transmit a pulse electromagnetic energy to the transponder chip. The chip responds by sending a unique code to the car. The unique code can then be used to unlock doors and open the car.
In World War 2, a similar technology was employed to assist air traffic control to identify military aircrafts on radar. This type of chip messaging is still utilized today in the aviation industry.
These systems were thought to be clone proof, 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. But the technology behind these chips has been improved and they are now not completely duplicate-proof. This has led many auto locksmiths to upgrade their knowledge by learning how to read, write and program these modern chips.
Immobilisers
The Renaults are rather complex in how they operate when it comes to their immobilisers as well as keys. There are two systems in use that effect the way a replacement key is programmed to the car. The older system uses the "kill switch" that connects to one of the crucial car starting parts in order to disable it if the right key is not present. These are delicate devices that require a specialist to identify and repair them if they malfunction.
The latest system is simpler to use. It uses rolling security codes and advanced cryptography to prevent copying of the code from the key or ECU. This is what will be used in the replacement keys we supply.
Certain models even come with an earpiece that cannot be identified by standard transponder scanners. It is also unique to the vehicle. This is an extremely effective method to avoid hotwiring and is also difficult to disable using the standard key or transponder emulator. We have a product called the Renault Antenna Emulator that we can use to bypass this immobiliser on Renault Clio phase two models and on some Renault commercial vehicle fitted with ID46 Transponders. It works by mimicking operation of a transponder that is valid in the ring antenna and can be used on damaged keys or lost keys without removing the ECU. It has been approved and tested by Thatcham to give security to motor insurance customers.
