Try leaving the key in the ignition for 5 or so minutes, fixed mine this way. Also check the battery polarity you could have put it in the wrong way.

Its a keyless start/stop system, so no ignition unfortunately, just a wireless connection for the fob when the battery isnt working. Will check the battery though - fairly sure its correct but could be user error. Thank you

Hi, can anyone please tell me how to resynch the key fob after a battery change, for a 2018 A6.

I had the replace key battery replace warning, which I've done but the fob won't now un/lock the car. I can start the car by placing it on the key sensor.

Any suggestions welcome, thank you.
