Slide-hole

Lock

People whose hands tremble (Parkinson’s disease or the elderly) often have difficulties when inserting a key into a lock to lock or unlock a door. This can also be a problem for anyone when it’s dark. This system uses a different shape for the keyhole; it looks like a funnel. If you want to open the door, all you have to do is to put the key into the part around keyhole and push it straight in. The key will then slide easily into the keyhole.
