Maybe someone accidentally locked a baby in a car and couldn't safely break a window to rescue the baby. So they called the fire service. It is a hot day today. That happened to dm neighbour visiting relative last year. Been told to be very careful with these electronic keys, they can lock the car by itself. Luckly there was no breakage needed as the firemen put a wedge on the front window and fished out the car keys. She had put the car keys on the front seat whilst doing baby's seat belt, who was sitting at the back. She closed this door and the door locked itself. Firemen, says it happens a lot, people trust the keys to much and others make silly mistakes like giving toddlers car keys to distract them whist putting the seat belt on. Then closing the door and hearing the door locking.
