Intuitive Key / Key

Do you have the problem that always needs to check whether the key is upside down before insert into the keyhole? “Intuitive Key” makes user easier to take the key in the right direction immediately, preventing user from taking the key upside down that cannot open the door.
In order to it more intuitive, we change the side of key into a 45o curve. User can differentiate the direction of key directly, don’t need to insert again and again. Moreover, the little curve of “Intuitive Key” also provides a small gap, when put it upon the table. This small change makes user can pick up the key handily, even the elder.
