    Safe is tricky. Electronic door locks are supposed to fail open in case of
    fire or power failure.

    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.
