|The key and key door in-game|
Keys are Level Objects introduced in Mega Man Maker Version 1.2.0, inspired from the keys in Super Mario Maker and Make a Good Mega Man Level 2. These digital door-openers can open any Key Door from any side. Upon opening a door, a key is consumed. The player can store no more than seven keys at once. Collecting more keys after already having seven simply makes the key disappear. Keys cannot be placed in Enemies, and are unaffected by gravity, floating wherever they are placed. Checkpoints will save keys if they are not used up already.
Originally, the Key, along with the Key Door, used the same design as the ones from Make a Good Mega Man Level 2, whose Key graphic was in turn ripped from Super Mario Maker. However, it was changed due to the design not fitting the Mega Man universe.
Since 1.5.0, Bosses set to give a key instead on being a goal after defeat will give the Player a key. Keys obtained this way go directly to the player instead of being placed on the place the boss was defeated.
- SnoruntPyro gave WreckingPrograms permission to implement the Key and the Key Door from Make a Good Mega Man Level 2.
- The Key, along with the Key Door, were the final items announced for 1.2 before the release date was revealed.
