Poplock / Lock

We have all experienced forgetting our keys on the lock. This has caused people many troubles finding the missing key and creates a security risk.
Poplock is a design to solve this problem. It is like any ordinary lock, but with a built-in pop up device inside. After turning the key, the pop up device would be triggered and ejects the key from the lock. The user’ s hand would be able to catch the popped out key, and if the user’ s hand was not there to catch it, the key would fall on the floor, and from the sound of the drop, the user would be reminded to retrieve the key. Therefore preventing the user from losing the key.
