Kia Keys Redesign

This project was created for a Digital Design & Fabrication class assignment focused on accessibility. The goal was to take an everyday object and redesign its form to make it more functional, inclusive, and user-friendly. I chose to redesign my Kia Soul car key, aiming to improve its ergonomics and ease of use.

My Role

 As the sole designer, I handled every stage of the process, from research and conceptual sketching to 3D modeling and refinement. I began by identifying usability issues with the current key design, then reimagined its form with accessibility and comfort as top priorities.

Process

Because of the nature of this assignment, I carefully broke this project up into 3 parts in order to maximize the accessibility I could bring to car keys. 

1. Research and Inspiration

 I started by observing how people interact with standard car keys and noting common frustrations — such as small buttons, slippery surfaces, and awkward shapes. I also researched accessible product design principles to understand how form, texture, and scale can enhance usability for people with limited dexterity or vision.

​

   2. Scanning and Modeling

 Using a caliper as well as contour gage (pictured), I was able to remodel my original car keys to use as a reference model. This allowed me to analyze proportions and design limitations before reworking the form. I then used Rhino to model the redesigned key, adjusting the overall shape to be more ergonomic and comfortable to hold.​

​

   3. Application and Refinement 

 In the new design, I made the key body larger and reshaped it for a better grip. The buttons were increased in size and slightly recessed to make them easier to locate and press without accidental activation. The form also features smoother edges and a tactile surface to make it easier to orient and handle without looking.
