Restricted Broaching 7-Pin Cylinder

[Chrispy]

I don't know whether this belongs in the High Security Locks section, but I don't have access to that yet (Memberships Pending ) so I'll just post it here. I have a restricted key cylinder that "doesn't work" anymore according to my employer, so he gave it to me to practice on.

It's a 7 pin restricted broaching cylinder that has an impossible angle at the top of the keyway. I can't even get my slimmest pick into the top of the keyway where the pins are. Any ideas how I would go about attacking this one?

Any suggestions appreciated.

If you search for "paracentric" you'll find a few tips. Someone (Romstar?) suggests actually making a "bent" pick that can get around the ugly top ward.

Either that or something like a bump key or whatnot where it's not an issue.

Any chance you could post a picture with a penny or a ruler or something next to it for scale, I have a few picks for paracentric keyways that just barely get in there-but my skill level isn't up to par yet, but I can manipulate the pins with some concentration.

but I can manipulate the pins with some concentration.

Wow. I have to use my picks. You are truly Yoda.

Here's a pic (albeit a blurry pic ) of the cylinder broaching. The angle of the top curve is next to impossible to get a pick into. Suggestions?

[cracksman]

Wow that's pretty tight. If you have a Peterson "Slim gem" you might get it in-may need a bit of sanding. Maybe a dental style hook also- it looks way out of my league- good luck!

Don't worry db I'll try to stay away from the darkside

Hmmmmm....... a slim gem..... dental style hook.......

*looks at cylinder, looks at pickset.... rubs temples... *

What you may want to make is a thin hook with a ( shaped profile along the side. Romstar wrote a post some time ago detailing how to make such a pick.

It is hard to tell from the picture as it is pretty blurry but it just appears to be what I believe to be a Yale keyway. I think the proper blank would be a Yale1. Like I said the pic is blurry so it is hard to tell. If your camera has a macro mode, turn it on and it will allow you to take close up pics more in focus. I just finished picking a number of these mortice cylinders for a locksmith a few days ago using a standard peterson hook unless I had a high setting pin and then I used a thin Lab pick to finish that pin off. Once you get the hang of manipulating your pick in the keyway you will find it is not too bad at all. It's the getting the hang of it part that may take you a few hours. Keep after it and you'll eventually get it. Also, what is this lock installed in? Is it in a rekeyable padlock or is it an Icore lock. If its an Icore lock it could be a completely different story as I have never dealt with or even known yale IC locks existed.

It's actually an Ilco cylinder, if that helps.

prolly ilco knock off of the yale ic

most likely a six pin because they are much more common than the seven pin but they do exist

if you count 8 pins then you got a 7 pin core (rare)

in a six pin core the seventh pins purpose is to retract the lug that keeps the core in the handle,mortise cyl etc and is similar in design to a schlage ic

if you had a working key you could cut the shoulder back on a y2 key blank and dup the operating key onto it.

cut a 3 or 4 cut into the end of trhe blank and you create a core key.

now the problem with these locks is the lug is made of steel
and over time it oxides and gets the thinnest layer of rust on the outside of the ic effectively fusing it into whatever it is inserted.

70% of the eime even with a good core key i wind updrilling and tapping a .25 /20 into the face of the lock and using a hammer to lever it out of its socket

yi kw i use half diamond

That is a yale 999 keyway also called Y1, you are over intellectualizing the problem, the pins are in straight drillings, you must put your pick in under the pins, then lift up inside these straight drillings. its not about a pick entering the top of the keyway, the pick enters under the pins and the pins are in wider holes without the restriction of that ward. a nice hook should do it.

I see. So should I try to pick in the number 1 ward angle or number 2 ward angle?

a nice hook should do it.

A round or half-round? I've got a nice round that i think will do the trick.

There is still very little working space but I think it can be done. Thank you raimundo. BTW, my order for those picks is on its way, it should reach you soon. $20US+$10US shipping. All information is inside the envelope regarding postal address, etc. Thanx.
