Door Mirror Knocked Out

[ScottyCal]

I just knocked my Cal's NS door mirror off its closed position. Have tried gently pushing it back in but didn't want to force it.
Is there an easy way of sorting this or do I have to remove the whole thing and redo then.?
Thanks

Sorted.... just pushed it harder and clicked back into place.
