CHILD LOCK in Trend line-Diesel

Look and Style - I have RED_Trendline, overall the look is smart & classy Comfort - I drive mostly everyday 40KM, the car is very comfortable. Pickup - I have concern with Pickup. As i have driven Maruti Swift & Fabia but Swift is much better in pick-up then POLO Mileage - Till now the mileage no concern, i am very happy. Best Features - Over all everything about the car is great Needs to improve - I NEED HELP, as per the sales person there is NO CHILD LOCK, anyone can help me or know about the same. One can lock from driver side door but from inside anyone can open.
