Plus also how to get White/Black Kyurem Kyurem Kyurem: Giant Chasm (After you have defeated Team Plasma) Level 70 The Three Golems Unlike previous games, you can catch all three Regis in one area. The difference is that you can only obtain Regirock at first, and you have to solve a puzzle which can only be discovered by visiting the area at day then at night. After obtaining Regirock, you will unlock the Steel Key in Black 2, and the Iceberg Key in White 2. You must activate the key via the Unova Link, and then you can obtain the respective Pokemon. You can obtain all 3 in one game if your friend shares the other key with you via Unova Link. All 3 are Lv. 65, further confirming that there is some villainous work going on keeping all these trio Pokemon at level 65.
