      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.

                      Fuck the electronics. A heavy crowbar with a pipe extension and you pull that box out of the concrete and take it with you without a problem.

                          normally the first wrong digit and the software locks you out like on pin and pay dvd. read the code however.....

                                      I a tech guy, work in technology, I hate these things. I like a good old fashion brinks manual combo lock safe. 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.

                                          if you can get to the solenoid wires apply a 9 V battery across the wires an bingo your in! 2 pinchers to break through insulation. one on each.

                                                            So lucky that cable was still oriented in the same direction with the receptacle. Proper digital safes come with a key lol

                                                              A good strategy is to buy a safe and put it in your office. It will occupy the time of the burglar while your valuables are hidden under a floor board somewhere.

                                                                A power-line attack is extremely unlikely to be successful on any device such as this. 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.

Would seem like a quick job if you made the tools in advance like they do in the movies. You were able to plug the cable in with 2 screwdrivers. If you had a longer forceps it would seem easy to plug in your own cable. You should try it. :)
