Safe is tricky. Electronic door locks are supposed to fail open in case of fire or power failure. -----Original Message----- From: Mister Coffee [mailto:live4java () stormcenter net] Sent: Friday, June 18, 2004 12:38 PM To: Richard Rager Cc: Amit Deshmukh; pen-test () securityfocus com Subject: Re: RF code scanners On Thu, Jun 17, 2004 at 05:19:09PM -0600, Richard Rager wrote:

Openers are decidedly susceptible to jamming...All FCC class C devices are susceptible to jamming. Look at wireless alarm systems.
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.
