This lock has been a thorn in my side for a long time!The tolerances are extremely high,the key bitting is a series of high/low cuts and i think it has spool and spool hybrid pins.sorry i takes a while but i think that is the quickest i've ever done it!
Sorry it takes so long to pick this but it has really high tolerances and tumbler spring like you wouldn't believe!
Although it's a Yale i have a 38mm steel Chubb which is the same in every detail except it's not shrouded and that put up a real good fight to.
This lock is Quite an awkward lock to pick due to the tapered key pins.There is very little room to get a pick in and manipulate the pins and once you've got the false set you need to be right on the tip of the key pins to set the pins otherwise you tend to overset them.
Big thanks to Wizwazzle for this lock.It's an American 1105 with a 5100 core which is identical to one that Wiz has and featured in a recent vid! it has all serrated pins and a crazy bitting!
I was given this set of Auto jigglers by a locksmith friend of mine and just had to give them a try!
Sorry if you get a bit sea sick watching but it was hard to steady my phone and jiggle at the same time!
