As for my 100th post, I'd like to contribute a little to this project!
First of all, this is just a first sketch. I though about this a couple of days ago and I still haven't trimmed the edges. I'll just share it so you all can tell me if it is a viable project, and then, if it is, I'll get into details (protection against destructive techniques, etc).
And the images where edited with MSPaint. Again, this is just to illustrate my idea. Later I'll have a friend (who is a designer) that will help me to make a good work.
So, my (hard to pick) lock is based on a restrictive keyway. When I'm picking Dimples, the stuff that bugs me the most are these edges (it doesn't necessarily make picking harder, but it annoys me):
So what I thought was to extend the edges and make walls instead. All the way in the lock. So it would be something like this:
And the key would have cuts like this:
This key isn't for this lock, and the cuts aren't aligned with the keway. Again, it's just a demonstration.
But the point is, a lock with bottom and upper pins with a keyway that restricted. It would make very difficult (I don't want to say impossible because I don't think there are absolutely unpickable locks) for merely insert a pick in there. For actual picking, would be a real nightmare.. Even with very slim picks, it would be impossible not to overset a pin by reaching to the one behind. That combined with serrated pins (and maybe serrated key pins also) would do the trick.
It can of course be combined with side pins, or side bar, or whatever improvements we may think of. But the main point is to make a keyway so restricted that a pick wouldn't even fit in there, and if it did, wouldn't be able to manipulate the pins.
I would have to be able to design a key with cuts on it's lenght that would be resistant enough not to bend easily, but I think I made my point.
Is this idea worth improvement (so I can think in anti-bump stuff, anti-drill plate, and other protections for it)? Or am I missing something important that would allow it to be picked?
Summarizing the hole idea:
1. Make a keyway so restricted that it would be virtually impossible just to insert a pick in there (even a custom one), and succefully set the pins
2. To outcome the "virtually impossible" barrier, add other layers of security like serrated pins (upper and key pins), or sidebars, or any other
3. Make it cheap enough so it can be used by anyone, not just government and rich folks
4. After that being accomplished, add layers of physical security to prevent bypasses and destructive entry
Thank you!
