I have a renault megane 99 model. We purchased it in 2004 and this is the 3rd time this year that it has immobolised itself. I phoned a garage who said that I had to go to the dealership with a renault as they are not able to fix it.
The dealership charge a min of £160 for this.
We are getting a black box fitted this week which bypass the immobiliser.
