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.
This is a Yale X5 6 pin high performance cylinder which is said to be anti pick(that's what is claims on the pack) and that's why i got it just to see what it was all about
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!
Another lock from work that i rescued!It's a 6 pin lock a few of whichare spools.The plug has no spring tension.It's meant to be extra high security....
