i have an idea for a release method. Its very simple and kind of fail safe (if not, please share your doubts):
I thought about fixing a piece of organic material into a high position (a stiff piece of Lettuce or a flower with a smooth stem...) so that it's sticking out of the edge. My english is not the best, so i'll add a picture

The Idea is to simply put the Key on top of the part that is sticking out. Now you simply have to wait untill the Lettuce or Flower or whatever to go limp which will drop the Key. For now, it's only a theory i want to share with you, but i think this one can become a very acceptable release method, once someone found the best material. By using different types on plant/vegetables you can increase or decreade the time you'll have to wait until the key drops
