Hello together This morning I wanted to get into my Seat Leon 2.0 TDI 2017, but the door didn’t open. Since I had to work, I used the spare key. Before I could change the battery of the main key and it now works again. The same thing happened to me quite exactly 6 months ago in a parking garage at night. The towing service had to come because I got into the car, but with the start button the car could not start. Wi e does it look like the battery life for you? In addition, it should be pointed out to the driver in the instrument cluster that he should change the battery soon? With me it was not the case twice. Greetings Lukas
