As of today, the Unlocker subchip no longer exists. This means several things:
-They will no longer drop as a chump prize from Purple Mystery Data.
-You can't buy them in the shop anymore.
-Purple and Red Mystery Data no longer require 1 and 2 Unlockers to open, respectively.
-You can now freely use Mystery Data as Disco balls and/or take them with you.
-If you got chumped into owning one of these subchips, you may make a post here to get a refund.
Also, expect more Mystery Data changes coming down the pipe. Eventually. Maybe.
