A:Answer The plastic receptacle attached to your Keurig (i.e. the piece your K-cup sits in while you are brewing coffee) actually comes out, and your Universal My K-cup replaces this piece entirely. Open the lid of your unit, place your finger directly underneath the part of the unit where the receptacle sits, and press gently back toward you. The receptacle will pop out, and you can then insert the My K-cup receptacle.
