Well not really, other than steel, pot metal and magnesium.i in no way mean any dis-respect to be klear , you have done a excellent job outlining the step by steps in the first posts of this thread
please know that ...
the the metallurgy of Toyota locks , keys , and internal parts tumblers , springs , cylinder cores and bores is different then the same era Detroit big 3 had ,
as well as many other non-Japanese auto makers at this period
the TOKAIRIKA corporation is TOYOTA's OEM locks and anything keys maker , was in 1962 first FJ40 , heck even FJ25 , and still is today in 2022 , they are under the
BOSCH company now formally known as the ROBERT BOSCH a NipponDenso Company ..........
After Robert and the DENSO and Nippon family's had a TIFF , you can call it , all 3 split and there simply called DENSO now , BOSCH is BOSCH and
the NIPPON's are lost to pages of history ?
TORKAIRIKA , still was TORKIRIKA during most of the 91-97 80 series production , but scooped up by BOSCH and now goes by TORKIA only under the watch full eyes of BIG brother bosch
in the 1990's TOKAIRIKA used ALL steel tumblers and a Pot metal cast main lock cylinder , and a magnesium core or bore , part that rotates , our friends key is binding in and stuck bad from what he discusses above ?
i admit i had to and wanted to , dust off lock and key 101T student training manuals , because , in my 30+ years since T-TEN i have never crossed paths
with a person trying to fashion there own Toyota key with a hand file ? this is new and unique and different ....
and after he added the additional tech and facts , or as i might put it lightly , fessed up and came clean on the story of how this key became randomly stuck to
the why behind all things toyota and stuff ..........
i sat back and sipped a ROLLING ROCK , and indeed ponder the next move here ?
i can openly admit , i don't know SH#T about self fashioning any Toyota key , but now i have decided to help the person , get un-stuck because that's the right thing
to do here on MUD ,
if anyone thinks its all HAHA HA toyotamatt blew the dust off his T-TEN bourse books , photos or it dont exist rules apply 100% is fair
- when he wakes up i am going top offer @VonArnim a face time , to see closer if my snap ring idea will work ? if not he can mail me the lock stuck key inside and
all take a solid crack at removing key carefully and making his ign. - lock a quick as possible tuen around for him , there will be NO service fees involved here for him
Karma is king in my JIS world ........
i hope i explained the graphite use in a toyota well enough for you to understand ?
The only thing that gets my attention there is the magnesium. The metal properties may influence usage. Now I will read more.
I'm all for helping if possible. I'm guessing the pins have hung up on a worn area and he needs to jiggle, bump, and rotate at just the right combination to get it out.
I think percussive maintenance is in order.
