Latest figures show more than 2200 children needed to be freed in the past financial year.
The NRMA was called out to 2210 incidents, with children as young as three weeks being accidentally locked in cars outside schools, childcare centres and shops, reports The Sydney Morning Herald.
Figures from the Ambulance Service of NSW show that since August this year paramedics have been called to 27 cases of children and babies trapped in cars.
An NRMA spokesman, Peter Khoury, said parents often handed children the keys to distract them while they loaded the boot with a pram or groceries, but the latest technology means even toddlers can inadvertently hit the immobiliser.
Another common mistake by parents is locking keys in the boot after a child had been strapped into their seat.
An RACQ survey has highlighted the risks of leaving kids in cars.
It showed the temperature took as little as one to two minutes to rise from air-conditioned levels to ambient and as little as seven minutes to reach 40 degrees.
If you do accidentally look the kids in the car, RACQ recommends you:
- Keep calm, think clearly and act quickly
- Call your roadside assistance immediately and if there are any concerns about the child’s health, call emergency services on 000.
