2011 VW Key Button Guard

I have a 2011 VW Jetta Clean Diesel TDI. I love the car, but I
really dislike the key that comes with it. The key is a "switchblade"
design where you press the button (in the lower right of the picture)
and the key swings out.
.
The problem with this is that the button protrudes from the rest of
the key and any little bump opens the key - even when it's in my
pocket. It's been annoying me for a couple of years.
.
This fix is actually pretty simple. I made a little guard that you glue
around the button with superglue. It prevents the key from being
accidentally opened.
.
I've included the skp file in case anyone needs to modify this for a
different key. See instructions for how to install it.
