How secure are electronic locks used on safes?<br />Dave tries a basic first attempt power line analysis attack on a standard La Gard (LG) 3740/3750 Basic electronic digital lock on a CMI home safe.<br />Can you crack an electronic digital safe lock with just a resistor and an oscilloscope?<br />All sorts of safe cracking techniques are discussed - thermal camera imaging, bumping, drilling, and spiking the solenoid.<br />And naturally there is a complete teardown of the La Gard lock and a demonstration on how it works.<br />And then Dave does something incredibly dumb, and has to fix it the old fashioned way, Hollywood style.<br />It's a tail of epic fails and stunning wins.<br />Part 2 is here: https://www.youtube.com/watch?v=mdnHHNeesPE<br /><br />Forum: http://www.eevblog.com/forum/blog/eevblog-762-how-secure-are-electronic-safe-locks/<br /><br />http://www.kaba-mas.com/media/654586/v4/File/basic-basic-plus-series-brochure.pdf<br /><br />ST ST62T25 OTP Microcontroller<br />http://www.alldatasheet.com/datasheet-pdf/pdf/23746/STMICROELECTRONICS/ST62T25.html<br /><br />AT93C46 http://www.atmel.com/Images/doc5140.pdf<br /><br /><br /><br />EEVblog Main Web Site: http://www.eevblog.com<br />The 2nd EEVblog Channel: http://www.youtube.com/EEVblog2<br /><br />Support the EEVblog through Patreon!<br />http://www.patreon.com/eevblog<br /><br />EEVblog Amazon Store (Dave gets a cut):<br />http://astore.amazon.com/eevblogstore-20<br /><br />T-Shirts: http://teespring.com/stores/eevblog<br /><br />Donations:<br />http://www.eevblog.com/donations/<br />Projects:<br />http://www.eevblog.com/projects/<br />Electronics Info Wiki:<br />http://www.eevblog.com/wiki/
