Renault Immobiliser FAQs

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 on your car, we will need to either see the car or the immobiliser control box. The control boxes may vary slightly between vehicles and models, but they all look quite similar. The immobiliser control box carries out a lot of other functions on the car, other than the immobiliser and so your car will not work without it plugged in. When we have finished the procedure and returned the control box to you, you should 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.

If you are having difficulty finding your control box, please call us on 0121 308 0819 and will will tell you the location for your vehicle.

The Megane and Scenic control box is known to suffer from water contamination.

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.
