[Luc s1]

i get a message battry key low once.
I forgot to chance the battery in the key.
Result No entry to closed car, i opened the door with the key and the alarm went off.
I tried to start the car with the start button but on the board message key not reconniced.
I didn’t found how i must start the car with the key .
Luckely i wasn’t far from home and my wife brought me the spare key ..
No problem and after changing the battery in my key Everthing is okey.
It must be possibel the get into the car and set the alarm off and start the car even with a flat battery in the key !!???

We just had exactly the same - 2 years to the day from new. 1 days warning, then flat - Just changed the battery! A bit more warning would have been helpful!

This happened to me about a few months ago. The car sits in the garage most of the time due to my work commitments, so no warning. One day I went to drive it and the doors wouldn't open. I didn't even think it might be the key, I just thought the car battery was flat. So I opened the door with the key and the alarm started going bananas and wouldn't turn off, so I got the spare key and all was fine. A bit premature for it to go after just two years isn't it ?
