High Security

[misspent youth]

Im just a little curiouse about high security locks. So any info would be great. My questions are:
What makes a High Security lock so secure?
Are there any locks that are impossible to pick

[Varjeal]

These are some of the things make a lock high security. (in no particular order of importance)

1. Strict key control, and patented key protection and parts.
2. Pick Resistance.
3. High quality materials. Tight machining tolerances.
4. Physical attack resistance through hardened materials, strategically placed inserts on possible drill points.
5. UL437 compliance, which includes all the above and more.

Impossible to pick? None. There are some that people probably haven't figured out yet.

Just a short wisdom... and a reply to your 2nd question:

people make it, people break it,...

(do you think i could get copyrights for this? )

I would define a high security lock as a lock that has 2 or more locking features, so if 1 of the locking features is compromised the 2nd holds up, not to say that the second won't/can't be compromised as well. examples being Medeco locks when picked to the shear line then the sidebar comes into play where the pins would then need to be rotated properly to defeat the lock, Mul-T-Locks when you pick the outer pins you must then pick the inner pins(which are much more difficult) BiLock you must pick one side then the other( neither is easy because the lock uses sidebars instead of upper pins) and there are many more but I think you get the point. The other things that were mentioned previously in this thread are true as well like patented key control to prevent unauthorized key duplication , and resistance to physical attacks is a must as well. UL(underwriters laboratories) tests for all of these things, in order for a lock to be UL437 rated it must hold up to methods of covert, and physical attacks for a certain amount of time, so if a lock is UL437 rated you can be sure that it's a high security lock. and to help you not get confused the word high security is used often when dealing with locks but just because the company that makes the lock calls it high security doesn't mean that it is. for instance Master Lock calls plenty of there locks high security but they don't make a single truly high security lock. so i hope this helps you get an idea of what high security and good luck with your picking

What the heck happens at 40 posts?

[Olson Burry]

The "magic".... duh.

selling stuffs?

[Olson Burry]

O_o I didn't think of that but no, you only need 25 posts and 60 days membership for selling your stuff.

Could be referring to the fact that 40 used to be the limit for applying to the adv section but it's higher now.

Anyone who thinks UL 437 is 'high security' doesn't know much about security. For example, many of the locks that are UL 437 certified can be easily bumped open.

Lot of High Security locks can be compromised easily, by bumping or by other simple techniques including by-pass for example. They still are High Security locks.
So saying that UL437 is High Security seems coherent (Actually, I don't know UL437, it doesn't exist in France), but High Security means that the lock is protected against some attacks, not that it is effectively immune.

Otherwise, we could not have the pleasure to open High Security locks if the are considrered low-security since we can open them without the key

Just my two cents

ROTFL

I'm happy to add my 2 cents to yours, so now we have 4.

This is the best answer I have seen for the occassions when people ask me why I pick locks for a hobby. There is a certain pleasure I feel inside in accomplishing the act of picking a complicated lock that is advertised as pick proof or high security.



Rage Against the Machine said it well:
We'll strike a match and it'll catch
And spread the insight we need
A tiny fire burning bright
Shedding light on the darkness of greed
