It’s amazing why people have never thought of developing this simple product that can be very handy. Concave lock helps us to insert our key to the door’s keyhole easier, yes, it is very handy at night due to its fluorescent material. It illuminates the keyhole zone with its annulus device helping you to unlock your door easier and faster. So simple yet so handy.

And here is why. The average locking mechanism has a certan volume that can not be manipulated in any other way but redesigning/reengineering it. So if the concave lock is used the door would have to be considerably thicker.
And sudenly the price of one lock is no longer economic.
This ofcourse doesn't apply to specials like the anti burgular doors wich are already very thick.
Where can we get more information like dimensions and where it can be purchased?
It's only a concept at this moment, it's not commercially available yet.
