Chests that require a pickup to open can be opened with explosions. - Key Blocks can be destroyed with explosions.

Mega Satan, or the flesh door to 
Mom's Heart in 
Mausoleum/
Gehenna.-
Haunted Chests and 
Mom's Chest.

Mega Chests require multiple explosions in order to be opened, just as when using keys.
Synergies[ | ]
Notched Axe: Allows the Notched Axe to open locked chests and doors. The opening of chests does not use durability; however, when opening locked doors, only every other door does not use durability for the first four doors opened on the current floor. If Isaac uses the axe's durability or puts away the axe, the other door uses durability to open.
Options?: Bombing any chest spawned by Options?, including the ones not requiring keys, allows picking up the contents of the chest without the other reward disappearing, unless the empty chest is touched. This can be easily avoided by simply exiting and reentering the room.
Sulfuric Acid / 
Terra: Locked doors can be opened by shooting at them.
Interactions[ | ]
Blue Key: Doors opened via explosions will not spawn the corridor.
Golden Trinket / 
Mom's Box: No effect.
Pay To Play: Doors can still be opened up normally via explosions.
