I did it again...
I was sitting inside the car and open up My door. Then I locked the car by pusching a buttom at the key, put the key at chear and walked out.
SLAM - the door was closed and locked. The key inside...
Had to call assistance from a Tow Truck. They use Some tools and open up My car without a key in 2 minutes.
Third time in 10 month I had to use this...
But last time it was not My fault.
If you Only have one key - take care of it.
Stupid me....
