Filtering JSON objects with jq

I have a JSON file which contains unneeded values. I want to filter them by only selecting those I need, or deleting those I don’t need. For example, I have this JSON file:

{
 { "id"    : "1",
   "key1"  : "val1",
   "key2"  : "val2",
   "name"  : "someone",
   "age"   : 39,
 },
 { "id"    : "1234",
   "key1"  : "val1",
   "key2"  : "val2",
   "name"  : "someone",
   "age"   : 39
},
{ "id"    : "4567",
  "key1"  : "val1",
  "key2"  : "val2",
  "name"  : "someone",
  "age"   : 60
 }
}

My aim is to get the following JSON, by deleting all key1 and key2 items recursively using a jq command:

{
 { "id"    : "1",
   "name"  : "someone",
   "age"   : 39,
 },
 { "id"    : "1234",
   "name"  : "someone",
   "age"   : 39
},
{ "id"    : "4567",
  "name"  : "someone",
  "age"   : 60
 }
}

Thank you.
