This answer answers the question of how you would pass the key to a child component. If you just want to get the current key from inside the child component, use the highest voted answer.

key is a special attribute in Vue. You will have to call your property something else.

Here is an alternative using pkey instead.

console.clear()
var pItem = {
  props: ['pkey'],
  template: '
',
  created: function() {
    console.log(this.pkey);
  }
};
new Vue({
  el: '#root',
  components: {
    'paddock-item': pItem
  },
  data: {
    paddocks: [{
        key: 1
      },
      {
        key: 2
      },
      {
        key: 3
      },
      {
        key: 4
      }
    ]
  }
})
