I found a pair of NOS keys for a Cadillac I once owned. The keys are new, uncut blanks, code 'J', (square head), and a
"K" (oval head) keys. Fits: 1970, 1974, 1978, 1982 Cadillac.
These keys are also referred to as B46 and B47 keys.
these keys have the Cadillac crest on one side and the GM logo on the other side. These keys were purchased at Norwood Cadillac in Norwood Mass., (where my 1982 Cadillac Fleetwood was originally purchased)
$20.00 for pair shipped to you in continental USA.
Thanks for looking. Will post any new "discoveries" I find in my garage.
