Mom's Key is a passive item.

Effects[edit | edit source]

  • Gives Isaac two keys.
  • If a non-Red Chest spawns hearts, coins, bombs and/or keys, causes the chest to spawn a second group of said pickups, effectively doubling the average pickup yield.
  • Added in Afterbirth This item belongs to the Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

Notes[edit | edit source]

  • Mom's Key cannot change the contents of a chest; it will only cause it to spawn extra pickups.
