Hardest lock to pick

a key.. ASSA, a 6 pin, or a 6 pin or better Medeco, NOT the cam lock of that one either.

the old S&G combination lock might prove interesting as well..

an MR402 Safe lock, too ANY of the new S&G or similar, pushbutton safe locks..

Newall's Parautoptic lock.

Try and get an electric utility 'padlock' (I saw them in San Diego years ago) which have no keyholes or dials. AFAIK they are opened with a big pair of bolt cutters. He will never be able to pick them.

Medeco, abloy, Assa come to mind. Medecos would be fun, cause they look fairly conventional.

Almost any 6 pin Schlage cylinder you take to a locksmith and get it pinned l,9,1,9,1,9 would be very difficult.

I thought that was Hobbs' Parautoptic lock?

MACS violation? or you might just get away with it with careful cutting.

Originally invented by Newell of New York. Taken to the UK by his salesman (Hobbs). Improved by Hart in 1863. Further details on my site. With regard to getting one to pick - might be hard ! there are'nt many around and collectors could be a bit relucant to let someone play with one ..........

yes, violation,, but, if you didnt make a key, then go

Key - impossible perhaps.

Picking - probably very difficult.

Rapping - such a combo may be pretty difficult to rap.

Shimming - should work as normal.

Most well designed restricted system keyways have such a tight & contorted broaching that it is impossible to insert a pick or gun in them and make any worthwhile contact with the pins, let alone trying to insert a turning wrench. I detest the #9 cut in the first or second position of any key. It is a real weak spot, and prone to bending and breaking. Then again, if you have a customer you dislike, then 1,9,1,9,1,9 would be an appropriate combo for them. :-)

What is the point of having a lock combinated so is hard to pick when it is not possible to make a working key fit for every day use for that lock?

Agreed that is a possible interpretation, but in making up a 'challenge' lock for picking a reasonable person would expect the lock to be in normal working order and can be verified as such by using a key. Otherwise a cylinder could be arranged so it is impossible to pick especially if the bible has a removable cap.

A possible combination that passes muster for MACS of 7 is 928170 and would be as challenging as 919191. Alternatively 718292 to minimise the chance of a broken or bent key.

You are curious, wondering why someone would apply common sense to a posting asking about pinning a lock so it is difficult to pick ???

Ummm... What is the purpose of practicing picking skills on a lock keyed up to a combination that should never exist in a keying system ??? Especially one that violates the MACS for the type of cylinder in question...

A person who may be picking locks that are installed and in "normal use" will hardly, if ever, encounter a lock pinned to the specs being discussed...

sounds to me like he's just got a smart assed mate he wants to stump..... who needs a key?
