Hello Don,

You need to have written down or somehow noted what key you have to get a replacement key. For example if it was 308 you'd get Replacement Tube Keys for Fastway Universal Coupler Lock - Key 308 # FA-KEY-308.

Without this it's impossible to determine as there is no type of indicator for these couplers like the Fastway # FA86-0015-308.

I've added a link below to all our Fastway replacement keys if you come across it, but there's not a way for me to tell you how to find a key number, unfortunately.
