Mom's Locket trinket
Mom's Locket is a trinket in The Binding of Isaac, added in the Afterbirth DLC.
Description
Using a key to unlock a door, Locked Chest, or Key Block, will heal Isaac for half a red heart.
Converts all 
Half Hearts into 
Hearts. This works retroactively.
Also works for Keeper's coin hearts.
Will only work when a key is consumed from Isaac's inventory, meaning that having a 
Golden Key will not provide healing.
