I have a S5 2014 I’ve had this car since 2014 had no problems last week I go to lock my car as I always do using the touch lock on the car and it didn’t work so I locked it using the key, works fine. Next morning I go to unlock it using the handle doesn’t work and hasn’t been working since! Anyone have any idea what could be the problem? Or has this happened to you? I Would really appreciate any advice or anything to try resetting, as it has been a week of standing outside in the Canadian cold weather trying to find my key in my bag!!!
