It happened earlier this week. Parked my car, ignition off, remote key still inside the car (in my backpack at the back seat), all 4 doors closed, went for the trunk for something, accidentally pressed the trunk lock button, trunk closed & all doors locked with the remote key inside the car.
Fortunately, the spare key was close by for the rescue.
Didn't know it would lock with remote key inside the car. So, be careful, guys.
