The Renault immobiliser sytem will NEVER stop the vehicle once it has been started. If your Renault has stopped while the engine was running the problem is NOT the immobiliser.
The immobiliser will only prevent the car from initially starting.
The Renault Immobiliser system is very complex. It is not just a case of changing a couple of wires and the immobiliser is overridden.
In order for us to carry out any work we will either need to see the immobiliser control box, or the key number. All Renault vehicles have different systems. The control boxes may vary slightly between vehicles and models. With the immobiliser control box removed your car will not work. When we have finished the procedure you will be able to just plug it back in and the car will start.
It is a great help to us if you can send the original remote key fob with the control box. If you have a remote key fob that is still operational, it will still work when we return your control box. If this key fob then stopped working, your immobiliser would still be deactivated.
Please do not send us any control boxes that have been tampered with.
The Megane and Scenic control box is known to suffer from water contamination. If this is the case a replacement box is required. WE CANNOT REPAIR WATER DAMANGED CONTROL BOXES / ECU’S. But we CAN clone the information from the damanged box to a new box.
All of the work we carry out carries a 12 month guarantee.
We recommend that when you send your ECU to us, you use special delivery as each control box is unique and cannot be swapped with one from another vehicle.
We always try to complete work with 24hrs, however sometimes it may take up to 48hrs.
