Thank you! yes! I contacted the original
1963 key/lock manufacture yesterday (still in business!!!!!)they will be quoting me on new cylinders and/or new keys. I was able to confirm that keys are NOT available through standard locksmiths & key cutters etc... Good to know after going to over 10 business's in an attempt to get keys made... My locks work fine... I only have one key and its integrity is compromised... Only a matter of time before it breaks or gets lost.... So thrilled to be successfully preemptive on this one.... Z.
