I had faced this issue of the doors of my Volvo XC60 getting locked with the key in the keyhole inside the car. This happened on two occasions. The first time, as I was away from my home and I had to get my papers which was inside the car , I had to break open the glass to open the door. Second time it happend two days ago, I had to wait for my duplicate key to open the doors. Has anyone faced similar problem?
