Hello dear forum, I have a very strange and urgent problem with my Twingo. Both radio keys have given up my mind, with both the vehicle can no longer be opened. That alone would not be the problem but without the radio unlock the immobilizer does not go out, so that I can not start the car. I was the first to think about empty batteries and at least changed them in one key (CR 2016 3V), but shortly afterwards it went away but then wa I don’t know what’s going on with the keys, at least that’s why I can’t move the car anymore!! Do you have a tip on how to start the car anyway or what can be done with the radio keys?? In the user manual there is nothing special about battery change except that you should pay attention to the poles. Renault gave me the helpful information you would need keys and car to find the error ……. just like if I didn’t have the engine t can start. Thank you for your posts Greeting Krontaler!
