I don't know what's normal now but a long time ago, 1997, I moved with a complex with 300 garages each with a remote. I opened the remote to change the battery and noticed only 8 switches for the code. 256 codes, 300 garages, drove around the complex opened 2 other garages. Even at 12 bits with 300 garages the odds are very high of a match

Which should I consider more insecure: my garage door, or the deadbolt on my front door? I wonder how commonly lock picking is used in crimes. I've picked a lock before myself, but I have no real idea how effective locks are in stopping people that want to commit house thefts. I expect an automated garage door opener is much easier to use than a lock pick though, and probably easier to produce and distribute than loc…

My parents did the thing where they put keyed deadbolts on all of the doors. So when someone wanted to break in they broke the glass on the door, discovered the deadbolt, broke the glass on another door and discovered the deadbolt, then broke the glass on a third door before yet again being foiled by the deadbolt. Then they broke a window and stole our stuff anyway. Apparently they were professional thieves too, sinc…

It reminds me of a friend that never lock his very old car so that no-one will break a window to see if there is something to steal inside.

The "source code" of http://samy.pl is quite interesting /* No source for you! *// /.source.replace(/.{7}/g,function(w){document.write(String.fromCharCode(parseInt(w.replace(/ /g,'0').replace(/ /g,'1'),2)))});

This is a reference to 'The Soup Nazi' ( Seinfeld )

No soup for you!

Locks reduce the instances where dishonest people can exercise dishonestly without repercussions. But that's what much of life is about, reducing the occurrences of negative outcomes. Elimination often isn't possible or feasible.

This is a much more accurate than the old "Locks keep honest people honest" saying. If you consider yourself an honest person, ask yourself how many times you've tried to open doors to random houses as you walk down the street. If you found it unlocked, do you rob the place? If you need a lock to keep you honest, you may want to reevaluate your values.

The phrase is rooted in a very old memeplex, the part where religious morality and sociopathy overlap. Most ideas revolving around the concept of "putting the fear of God into someone" aren't actually for regular people with empathy. They're for sociopaths. It seems that sociopaths used to be seen as just completely normal people, undifferentiable from everyone else—and much of "morality" is actually an attempt to create extrinsic incentive systems to replace the thing that sociopaths lack, so they can seemingly function normally.

That's all to say, by analogy: locks are to keep honest-acting sociopathic opportunists honest-acting.

Wow. That's hilarious. The vast majority of all garage door openers now sold are rolling code, but I bet almost all of them will fall to the coat hanger method.

While locks don't keep skilled criminals out, you'd be shocked how many unskilled ones there are. Meth/crackheads routinely go around twisting doorknobs in apartment complexes or pulling on car handles just hoping to find something unlocked so they can steal whatever is there. They (usually) don't break and enter, but if they happen upon an unlocked door they'll walk in and steal anything.

About 15 years ago, my aunt stopped locking her convertible. She used to, but people would slit the closed top to reach in and unlock the door to look for CDs and such to steal. A few hundred bucks to replace the top was way worse than losing some change and such. Then she switched to a late 90's Miata which had a lockable center storage bin/arm rest.
