Keys

[Stephen Pechenik]

I am trying to get my 1963 Sedan Deville Park Avenue road ready.  It is almost there.  The last owner must have purchased the car without keys as he removed the pins from the ignition lock tumbler and the glovebox lock tumbler.  Due to the fact that my local locksmith lacked original key blanks, I purchased octagonal head key blanks stamped "A" and un-stamped round head key blanks  all of which contained the Cadillac V and crest. displayed on one side of the key head.

According to my recently purchased owners' manual, the round  headed key is for the trunk and glove box while the octagonal key should be for the ignition and doors.  For some reason the round headed key fits into all of the locks while the octagonal key fits in none.

For some silly reason, it is important to me to put the key problem right.  However, to do so, I need different octagonal head keys.  Where can I find some?

That is strange that the octagonal head key doesn't fit. I got my key blanks at USA Parts Supply

The blanks are on page 23 of the catalog

The round head key has GM on one side & the Cadillac V and crest on the other but the octagonal head key hays GM on both sides.

Kurt, When you say doesn't fit do you mean it literally will not insert into the lock cylinder or just doesn't unlock the lock? It looks like the correct shape.
