via ajax
You can put it into your aspx page code and pass it to your js (if you are using asp). If Key is an object, you can serialize it to json string and use JSON parser to deserialize it. If it is a basic type, use <%= Key %> in your asp page is OK. (Note you cannot put the code in your js file)

<script type="text/javascript"> 
var key = JSON.parse('<%=JsonConvert.SerializeObject(someObj.GetKey()) %>'); 
//now you can use key in your js logic 
</script>
