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.
