A neat hack by Samy Kamkar (the actual code is bricked):

OpenSesame is a device that can wirelessly open virtually any fixed-code garage door in seconds, exploiting a new attack I’ve discovered on wireless fixed-pin devices. <..>

OpenSesame uses the Radica Girltech IM-ME texting toy from Mattel, as it sports all the equipment we need to pull off the attack – an effective TI CC1110 sub-GHz RF chip, an LCD display, keyboard, backlight, and more. And it’s pink.
