I wonder how many of these devices are designed to "Fail Open" when their receivers are overwhelmed. I don't imagine it would take much power to completely overload the front end of most garage door openers and the like.

The "safe" way would be to "fail closed" of course, but we all know how security conscious most of the manufacturers out there are.
