Fresh Water door Key

[texascanuk]

I can't seem to find who made the access door for the fresh water tank on the street side. I need an extra key made.

It's possible, I could use a generic lock on it that would be used on a tool chest or something because I noticed that it has a spring clip on the inside and would be easy to change. The key is a sort flat metal key with a dip running down the center.

Thanks,
James

This PDF from Airstream says that a '91 uses a "Deco 1" key for the water-fill door. Maybe Airstream dealers or Out of Doors Mart have the right key. The key I linked to for out-of-doors-mart says "70s and early 80s" for the Deco key, but Airstream's PDF runs 80s to early 90s for that key.
