I think it's a testament to human progress. We've never been as safe as we are today.
Maybe time to just leave the lock away then. It's pretty common in Scandinavia, and, at least for me as a tourist, had quite an impact on the societies' mood.
(I know lots of people in Germany who don't bother to lock their doors.)
This was handy for getting around the Institute after hours (steam tunnels).
Instead, I would read the material that Deviant Ollam has published (http://deviating.net/lockpicking/resources.html) or look for an upcoming TOOOL meetup (http://toool.us/).
(2) I don't intend to be pedantic – and perhaps I'm mistaking hyperbole for fact – but how could you are opening a combination lock with an secret unbeknownst to you more quickly than your a combination lock with a secret known to you? Unless, you're shimming the new lock and avoiding dialing the correct combination altogether, in which case you would solve them all locks in the same span of time, this is unlikely. However, you said you're opening the lock by 'feel,' so I assume that's not the case.
Given that, I could easily see how "feeling" that you'd hit the right digit (give or take) might be faster than focussing on visually actually hitting the right digits.
and yes, it actually was quicker to open them by feel than by looking at the numbers on the dial.
Yep, I remember in high school, in fact it was in Pasadena not far from Cal Tech, I don't remember who, but somehow I learned from somebody how to open the high-school lockers by 'feel', in a fairly short-time I could open any locker quicker than my own knowing the combo.
Locks are fairly amazing when you think about it the locksmiths and the criminals all know how to crack any lock, yet the people in the middle think they're secure.
Years later as a landlord I got to know my locksmith fairly well, one day by offhand he told me that the master-key ( So I could have one key to rule them all ) I was using could open 1/2 the units in the city.
