Renault Trafic Key Fob Review

The Trafic’s strengths include an impressively comfortable and car-like driving experience, plus good real-world fuel economy. The model that was updated in 2023 offers a number of Advanced Driver Assistance Systems.

The steering has a nice weighting and sensitivity, and was easy to operate in the van’s “parking gymkhana challenge (yours really nailed it, by the way). There’s also new renault key , which is supposed to dissuade thieves from taking your car.

Hidden Physical Keys

Modern car key fobs offer numerous useful functions, including the ability to start and stop the engine remotely. These hidden features are very useful if you want to get out of the rain or if your car is in rush. However, some of these hidden features can also be employed by thieves to gain access to your vehicle.

The key fob emits radio signals (RF) that are detected by the receiver inside the car. The receiver interprets the signals and determines if the button was used to unlock the vehicle or start the engine, as an example.

When the new key fob is added to the system, it broadcasts its serial number as well as the current synchronization counter to the receiver in a special learning mode. The receiver saves the information in memory and ends the learning mode. The key fob will then use the decryption keys previously saved and the synchronization counter in order to authenticate the signal when it is used again.

While this measure of security has proven effective in preventing the majority of attacks, it’s not completely foolproof. This safety feature has been abused by a sophisticated attack called RollJam [17]. The attacker must acquire future codes that are transmitted by the key fob to be successful however, once they are obtained, they could be used to execute an attack replay and gain access to the vehicle.

Pulling the Car Out of the Spot

A feature that is well-liked by people with Renault Trafic is the ability to open the hatchback and trunk with an option on their key fob. This is great for people who have a lot of things in their hands, such as food items or party supplies and don’t want to take everything off just to get the car open.

This is also an effective way to stop thefts from happening in the first instance. If someone is trying to steal your vehicle or attempt to break into your home, a quick press of the panic button will scare them off and alert neighbors to the danger. If you are feeling unsafe on the road pressing the panic button will alert drivers around you.

The primary reason the system may not be functioning properly is because the key fob might be damaged, either from dropping it or washing it. Other reasons for the problem could be a malfunctioning key programmed and an immobilizer malfunction and interference by other wireless devices operating at the same frequency. If you encounter an immobilizer module that is malfunctioning It is recommended that you consult an authorized mechanic or Renault dealer to address the problem. It is possible to change the fuse or disconnect the battery for 15 minutes to reset the module.

Sunroof Opener

Renault key fobs that are part of the traffic model have a sunroof opener that operates the opening and closing of your car’s sunroof. This is vital to ensure an appropriate temperature while driving in summer. This feature also lets you open the sunroof to vent the car, which can help with air circulation during a hot drive.

The sunroof can be opened or closed using the console switch on the driver’s side (left-hand drive) of the hatch area. The sunroof will be opened in a comfortable position which is about 75% open. This is the typical operating position in the majority of cars. Touch OPEN for full sunroof operation, and CLOSE to close.

If the sunroof isn’t functioning correctly, there could be an issue with the micro-switch between the sunvisors. It can be manually operated to control the sunroof drive motor long enough to check the current of the motor with an ammeter. Enlarging the adjusting screw will increase the torque of the slip clutch on the motor, and tightening will lower it. When the slip clutch is properly adjusted, apply heavy force Loctite to the lock nut for the adjusting screw.

Another issue that may stop your sunroof from rising is a bad Limit Switch 2 or one which has been improperly adjusted. The lifting arms retract to the open position to be removed, but not in the locked-open position. On 1985.5 and later vehicles the ignition switch should be in the position of the ACCESSORY (2) to operate the sunroof. The sunroof switch console must be pushed in the “A” direction to open, and then in the “B” direction to close.


The Renault Trafic has a lot to offer with a stylish exterior design and a few up-to-date features. Cameron who was driving the 2023 Renault Trafic in Sydney for the launch event was able to drive. It had responsive steering and was a bit heavy. It was also easy to park even in the narrow parking ‘gymkhana’ which saw yours truly reverse out the ‘garage’ in a witches’ hat and then into two more – not too bad for a vehicle that only scores three-star safety ratings by Euro NCAP.

If you notice an exclamation mark on your dashboard it could be due to the adaptive cruise system telling you there is that there is a problem. The system makes use of radars and cameras to monitor the traffic ahead and adjust your speed accordingly.

The yellow warning light, which appears like a car, with swirls, indicates that stability control is activated to prevent the loss of traction. It is usually accompanied by an audio alert. It should only remain in place for a brief amount of time before disappearing as the system works to restore traction. If it is on for longer, you should refer to the manual or seek assistance from an Renault mechanic or dealer.
