Aerodyne Owners ,
Copies of Zeni key blanks were manufactured by other companies .
Dominion in Canada had a "L62N"
Davenport - Burgess in UK had a "H024"
These I believe are a direct replacement for the Zeni used in the Aerodyne door locks, but possibly not manufactured for many years .
At least it is a starting point for a search .
There is surely an old established locksmith that will have some blank keys.
I know of a Dominion blank E122A that has been modified to fit .
The joys of owning a 401 - 403 . No wonder prices of 400's are increasing !!!
