Have you ever wondered if it was possible to 3D Print a funcational key? Well, it is and I can assure you it works just fine. I would not use it as a main key, but it is great to print a few spare keys to your room, office or house. Save your key on a usb stick or cloud drive and print it anywhere!
I only have 1 key to my office so I decided to test out a 3D Printed spare key. It works great and I haven't had it break on me after using it 50+ times. Like I said, it is perfectly fine for a spare key.
Step 1: Download OpenScad 3D Modeling Software
Download OpenScad here for your operating system. If you've never used or heard of OpenScad before, it is a great way to create customizable parametric models. This means that I could give an OpenScad model to someone with zero modeling experience and that can modify it just by changing a few numbers.
Step 2: Create Your Key
First, download the Kwikset KW1 or the Schlage SC1 file depending on the key you want to print. These models were created by Nirav Patel. Open the file in OpenScad and change the last line of the code by entering in the key code of the lock. Your key may have the key code written on the side, but if not you can measure the key and compare the numbers here.
Compile the program and then export the file to an stl that you can print. If you don't have access to a 3D Printer, you can use 3D Hubs to find a local 3D Printer near you.
