  OpenSesame attacks wireless garages and can open most fixed-code garages and gates in seconds using a Mattel toy

Samy Kumar did a project about 10 years back, where he worked out how to brute force a 12 bit garage door code in under 10 seconds, using a childs toy: http://samy.pl/opensesame/

My garage door opener uses a 12 but dip switch config (and my last place used an 8 dip switch config, and I'm pretty sure still does).

Re reading that OpenSesame post was fun. It reminded me of a few names I need to go find out what they're up to these days (Travis Goodspeed and Michael Ossmann are names I remember seeing doing/writing-up some really cool stuff), and that the Mattel IM-ME toy he was using uses that same CC1110 "sub gHz"
