The yale 7 pin Large format IC has a 7th pin in the back of the lock that your regular key can't reach.

If you have a key, get your 6 pin key duplicated on a 7 pin key blank, Don't cut the 7th position (at the tip).

When you insert this new longer key into the core, the first 6 cuts operate the lock pins and the 7th uncut tip lifts the control pin. This control pin engages with the locking tab on the side of the core and when you turn the key, the tab is pulled in, releasing the core.

Actually, I think the 7th cut is supposed to be a #1 cut but uncut works fine. If you have trouble inserting it into the keyway, file the tip down slightly to let the control key slide under some of the longer pins.

hi, in a Yale 7pins format the 8th pin is the one that engage and retract/extract the side retaining bar of the cylinder. regards

this was rather helpful, i have quite a lot of these locks, both in and out of their cores...i can pick some of them most of the time and most of them some of the time, but never was able to extract the ones in the cores...i'll give it a shot, seems like i should have a few broken/unused keys with high enough biting that i could make an attempt. thanks again.

Or you could just obtain blanks for the locks and cut your operating key onto them to remove the core...

A 7-pin blank for a 6-pin core and for the 7-pin cores there are many hotel variant Yale keyblanks in 7 1/2 and 7 3/4 pin lengths due to the differences in the way the various models of hotel keyed locks interacted with normal operating keys...

As others have stated, a #1 depth cut is required on the tip of the key to operate the core removal mechanism...

totally, thanks again for the help. i've got too many of these locks lying around not to be testing and retesting different methods. depending on the biting, they aren't too difficult to pick. thanks.
