Now that I have to keep a FOB in my pants all the time. . .
Found that once in a while I do end up hitting the Panic button, or lock/unlock the doors. Have not yet "accidentally" started the engine. But to prevent the occasional mishap, I came up with the following project.
Just a simple clip-on shield made from thermoformed Kydex™ plastic. One source of Kydex is http://www.knifemaking.com/category_s/105.htm
There are many others.
The attached pix show how I made mine. . . this is just the "Rev.1" prototype. The next version might feature some extended tabs for a better "grip" to the Fob body. This one is doing just what the doctor ordered for now!
