Some require the security key, some push button.

I purchased two white 5S 2K that has the push button to pop out the camera for battery access and doesn't have the anti-theft mount.  I liked them that I purchased three more black color but these require the security key to pop out the camera have has the anti-theft mount.  Same model number.  Any reason why they would switch between the push button and needing the security key and havingdifferent mounts?  I wouldn't see color having anything to do with the difference.

The color of the camera has nothing to do with it.

It's just possible that the one order included the secure mount option as a bundle and the other did not.
