Robert Green :
I've got the typical minivan keyless entry keychain fob but it's got a
serious design problem.

The buttons depress too easily and often accidentally when the fob is pushed
into a pocket or a purse. It's happened more than once, so it's time to do
something about it.

I had a similar problem with a Garmin GPS. I put a ring of hot-melt
adhesive on the surface around the button(s). It was a tricky job but it
looked good and worked perfectly.
