Yes, that's what they used when I accidentally locked my baby in the car. I didn't notice that the keys fell onto the car floor, I shut her passenger door and then I realised it was completely locked! I freaked out was such a scary situation. My phone was locked in the car too. Some awesome passer-by lent her phone and stayed around until help came. The roadside assist service and police came to unlock the car, using that gadget to pry the door open and a hook to grab the keys. I was so thankful. From that, my keys now live on a lanyard, around my neck.
