Slim Door key for interior doors safety lock V2

This is an updated version of my emergency door key for interior doors that have the slotted opening. Just like the original design, I wanted it to hide in the door trim for easy access. This new design is more “key-like” and feels more natural to use. It is also slimmer and barely noticeable if the same color as the door trim. 

In the pictures, the new design is red, the old design is green. Link to the old design.
