Bypassing a certain key slot.

[cynebald]

Look at this image of two key slots; the first, captioned Basic, is, from what I have seen, typical of Master padlocks and door locks, and the second, captioned Advanced, is mostly unknown to me except from a Yale padlock. Into a basic key slot, it is easy to insert a pick and manipulate the lock's pins, but into an advanced key slot, it is not as easy, for the design seems to inhibit picking.

Basically, what I wish to know is how can a lock with the advanced key slot be bypassed? Can traditional locksmith tools be used? How have you all bypassed locks with this type of key slot? Et cetera.

maybe bumping? Correct me if im wrong someone

Bumping wont care how the keyway looks. But you can pick those keyways fine using something like the Peterson "reach" pick, shown here http://www.peterson-international.com/individualpicks-detailed.htm#Reach, or something from the slender set shown below can also work. But I find for narrow and odd shaped keyways, the reach pick works really well, due to how thin it is cross sectionally, and the slight curve helps it to go around the keyway "warding".

slimline picks... I use SouthOrd...

that keyhole is somewhat standard in the UK and not "advanced".... I find I can rest my slimline picks upon the bottom ward on the right-hand side and pick that way. The wards are quite forgiving once you find the right place to use your pick.

If you're a locksmith, there are many ways to bypass restricted broaching on locks. Bump keys, slimline picks, shims, rotary pick ( ), hand files, etc.

Some things may be pick proof, but everything can be bypassed.

rotary "pick" - don't go putting dodgy ideas into their heads Chrispy

I can think of a few ways it could likely be bypassed...

thats not restricted warding as such though... might take a photo of a lock with fun wards later

I am curious as to why he wants to know how to bypass rather than pick though...

[Chrispy]

I think he's referring to how someone can pick a lock with restricted broaching, whether it be picks, bump keys, whatever.

Use thinner tools, a tension wrench can be inserted on the top or bottom of the keyway or both if you have a nice tool set,

Wrenches with a narrower end can be used or even a cut down key that still allows the pick in.

Nothing special about that keyway as already said.

when you look at that yale 999 keyway, do not forget that the pins ride in round collumns that are wider than that keyway, if you have a really difficult keyway, make the hook pick with hardened piano wire which is round. (buy a base string from a music store, unwrapp the copper wire around it) this pick will have the profile like this o which fits inside that slot whereever its at.

Very helpful, you all; I thank you all. I might look into getting a slimline set soon. I found an interesting PDF document on bumping that I'm going to read, for I've not heard of the method and am not familiar with it.

I've, for several minutes, tried picking the Yale (with the erroneously-termed "advanced key slot") padlock with slight difficulty (due to its restricting keyway) using a standard diamond pick, and I am able to manipulate the pins somewhat, but they don't seem to catch on the sheer line when I push them up, and also the plug doesn't seem as turnable with a tension wrench than other locks.
