At almost 30 degrees, a toddler accidentally locked himself in the car in Donauwörth, Bavaria.
The three-year-old stole the car key from his 29-year-old mother and then pushed the button to lock the doors when the woman got out and he was still inside, police said.
The boy then did not manage to unlock the doors.
The woman made an emergency call after the incident on Tuesday.
The fire brigade smashed a window of the car and then opened a door.
According to the information, the child was visibly overheated and was examined by the emergency services, but was then handed over to his mother.
