    You can open many of them by throwing them up in the air above a soft surface like a mattress, the motion opens the lock. No logic probes required :)

      7:22 Oh, so 'spiking' the safe has nothing to do with alcohol?

            Hello everyone , David if you hold a powerful magnet near the solenoid it will unlock (: guaranteed to work just operate the solenoid with Neodymium magnets magnet on from outside the box. you can hear it click. a bit tricky but you have to catch it at the right angle, this is for any digital safe

                    Wwwwwait a minute, ... where 5he hell is my 45 minutes?!

                    [Edit; you see that above? ... I'm in time-loss shock and it caused a typo. I'm feeling a little woosy. Oh! ... and — If the 2nd video goes into all the detail I expected in this one then double the comedically overdramatic tone you read the remainder in.. hehe.]

                    I would never spend precious time so frivolously, not for a forty-five minute, choreographed "No." — or a "Nooop!" — maybe be safe and say, "If you want to learn valuable information on the subject matter, then buy a book; if you want to spend near an hour trying to match the content creator's intoxication-adjacent exuberance to all things represented in a heterogeneous sampling of time and atmosphere, well.. don't humiliate yourself; you, like I, will never extract such pure joy and personal reward as our presenter, not even if we spontaneously adapt the ability to asexually reproduce.

                    I cannot imagine how sky high I would be if I'd actually learned what I assumed was going to be transacted but it's a good thing I'm in bed, prone, because otherwise it would have created obstacles to the screwing I just endured.

                    In all honesty, my takeaway isn't that bitter.. I was only being dramatic, but I've cereally got to learn how to compulsively parse anything and everything with the option; and I'm being ... super ... cereal.

                    Hey Mate, soory I didn't catch your name, but your ability to extract happiness from a teasingly long "No." gives me hope I just might be capable of cranking out at least half a smile of wonderment the next time I glance up at the night sky and catch a Milky Way adjacent hypernova spark off. 😁

                      When the spent battery is left inside for too long a time, the connector might corrode, and the circuit corrupted. You'd "lock yourself out".

                          Thanks very interesting. Can confirm the cheap safes are garbage no matter how good the internal electronic controller is just jabbing one of the leds (which protrude through the metal door through holes drlled in) even if you destroy the pcb in the process with a piece of wire bent correctly and knowing where to aim the resistance of the solenoid spring is no more than 10 grams and click turn the handle - safe open. 1 out of 5 stars would not recommend lol.

                            $800 dollars for a toy. But it complies with industry standards. Please do a video on use emp generator on electronic safes please.

                              The problem with this one is that lock and solenoid are moving in the same direction and 40kg safe accelerates faster and reaches much higher speed than you were bumbin at. So I don't really think that 800$ is a good price for this one. For 800$ you can make much better one, especially if you are engineer.

                                have you tried a large earth magnetic? just saw a video on doing that for other safes.

                                          So a hack would be to use the existing bottom holes and back holes to access the selelnoid wires or pull the connecter then weasel in power to the selenoid wires or connecter and Power the selenoid and your "in like flin", heck, may even be able to do this with the provided mounting holes with some creative modified tools and mini camera...

                                            If it locks you out for 5-10mins after 4 or so numbers of incorrect combination attempts, then it seems likely that you could easily reset that by simply disconnecting and reconnecting the battery after the lockout. I suppose it could have some kind of capacitor in there that is just there to store enough to keep the 'fault' condition from resetting on battery disconnect.

                                              You could embed a circuit just above the battery compartment, a data logger. Let the rightful owner enter the correct code once or a few times. Then retrieve that data, and manually enter it. Would likely be a bugger to attach. But maybe not.

                                                      There's also locking mechanisms available that have a redundant mechanical combo lock, as in, either one will open the safe. I like that idea because a keypad is more convenient, but a mechanical lock can easily last 40+ years, and if the keypad breaks, you can get back in without damaging the body or bolts, and just replace the locking mechanism. Dave's situation was the exception, usually if you have to break into your safe, the safe itself is a total loss afterward.

Have a small old safe from the late 1800's that still works great! so thick heavy (blast proof) no way to break into it easy. Have answer style brinks type about 15 years old. Wanted another so visited several retail places that sell them to check them out, all seem to have a lot of plastic these days, handles are plastic, and some were broken from handling, so that tells me not going to hold up well at all if broken in the store. some used a film type keypad that was worn from people pushing on it, there again not holding up to daily use if numbers are worn off useless. And then one would not work, store employee was going to change the batteries, opened up and was all corroded inside, never got to see it operate. Then I decided, not having one. but can't find anything without the damn electronic POS locks on them now.

Imagine how most people would naturally code this up, even in Assembly. Naturally, I think most programmers would just buffer the key presses, then compare the buffer to the stored code at the end. Therefore, any difference in current draw will only tell you what the device already does (Success or Fail). Interesting experiment, but IMHO terrible hypothesis. Moreover, I seriously think that lock could be bumped if you applied a little more force, or used a strong electromagnet.
