I originally made one of these last year for my Mother. After 30 years of being a Physical Therapist, the strain she put on her body and arthritis caught up with her. Her right wrist became unable to make certain motions without excrutiating pain. One of those motions was the twisting motion required to turn a car key. I came up with this simple device to help. It allows one to turn their car key by pushing and pulling rather than by twisting. ( Ironically Mom got her wrist fixed by surgery and now I use it because I broke a bone in wrist a few weeks ago).

You'll notice that the device shown in this Instructable is different from the one in the video . The device in the video is the original I built for Mom which is still going strong. The one shown in this Instructable is the one I built for myself. It promptly broke on the fifth or sixth use. This is because I used a wood the was too soft and incorrectly placed the key notch. I'll describe these errors and how to avoid them in later steps.

Step 1: Tools and Materials

For this project the only material you'll need is a hard wood dowel an inch in diameter. I used a hard wood for the original device, but (without thinking/realizing) used a soft wood dowel for the device documented in the Instructable.

I used the following tools. As always if you don't have them you can acheive the same effect a different way with what you have...or use it as an excuse to buy a new tool.

* Tape measure
* Bench vise
* Work piece protectors
* Router
* Straight cut router bit (I used a 1/4" bit. This will vary depending on the thickness of your key.)
* Drill with 1/4" bit
* Jigsaw
* Sandpaper
* Wood burner with tips (Optional)
