Transponder Chips

All modern Renault keys come with a transponder chip (sometimes called"chip key" or "chip key") built into them. The chip is a micro-circuit that communicates with the ECU of your car to unlock doors and begin the motor. When your car key is inserted into the ignition, the antenna ring on the ignition sends an explosion of radio frequency energy, which is received by the transponder chip. The chip transmits an electronic signal that contains the unique code. The code is read by the ECU to determine whether the key is valid and should be allowed to operate the vehicle. This can help to reduce theft of cars, since keys aren't just a metal key which is easily copied. Instead, they have an additional layer of security that prevents unauthorised access to your vehicle.

The older cars without transponder chips were easy to copy and thieves could easily steal them. Since most cars made after 1995 have a transponder, this type crime is much less common. This is because the car's microchip is uniquely linked to a specific vehicle and can only be activated when utilized with the correct key. If someone tries starting your car using a transponder that hasn't previously been programmed specifically for your vehicle, your ECU will not recognize it and will not switch on.

If you're looking to get a new transponder chip fitted to the existing key, a locksmith will generally do this quickly. Locksmiths use special equipment to clone the key that you have and then insert the transponder chip. The cost of this service will depend on the year, model and model of your car.

Immobilisers

Car immobilisers are a vital element of the security of your vehicle. They guard your Renault from theft by preventing it from being opened with the wrong key. Immobilisers have been mandatory on all new vehicles in the UK since 1998, but many older vehicles also have them fitted. These devices can enhance your overall security and can even lower your insurance costs.

The first car immobilisers came out in 1992, and shortly after most luxury automakers began installing them. They are designed to stop the engine from starting when the correct key isn't available or the transponder chip that is on the fob isn't recognized by the electronic controller unit (ECU).

When you connect your smart keys to your vehicle, they send an encoded code to the ECU that must match with the code to allow the engine to start. If the codes don't match the ECU will disable several key vehicle components including the starter motor and fuel system.

If you own an older Renault key that does not have the security feature, then you can purchase a replacement and get this extra layer of protection. It is crucial to make sure the new key is certified by Thatcham and has been programmed to work with your car.


A number of tech-savvy thieves have come up with ways to evade immobilisers that are fitted by the factory. These techniques involve the use of devices that duplicate the pin code from your key, and then transmit it to the ECU to trick it into believing that your key is in the vehicle. This is known as relay theft and is a frequent concern for people who own modern day keyless entry and start-up vehicles.
