Remotes
The hands-free cards offered by Renault are still widely used in their vehicles despite the fact smartphones are replacing them. In fact, two of three Renault vehicles have hands-free cards. The use of them has increased in recent years. In this video Pascaline from Renault's Products Division explains the way these cards work.
Renaults come with an immobiliser system that is a bit complicated. It is important to understand the basics before attempting to unlock a vehicle without the use of a key. Some vehicles have an emergency lock attached to the door handle of the passenger that can be used in the event that the keys stop functioning or the batteries wear out. This is an option for those who do not want to pay a professional locksmith.

This has led many locksmiths in the auto industry to upgrade their skills by learning to read, write and program these newer types.
Immobilisers
The Renault isn't the most straightforward when it comes to the key systems and immobilisers. There are two major systems that influence the way keys are programmed into the car. The older system utilizes a "kill switch" to disable a vital part of the car's starting mechanism if the proper key is not present.
