Removing Gas Cap Assembly Without a Key

you keep your lunch in the fuel tank 

So thats what Vegemite looks like?
Someone smuggling it into the US in FJ fuel tanks?

Unless you want to learn lockpicking techniques, you'll either have to drill out the lock and rotate the barrel manually or take the tank to a locksmith.
The locksmith will probably not charge too much, and will be able to make a new key for the cap so you can still use it.

Betwen my friend and I we have had about 10 Yamahas around here with vintage from 82 to 92.  There are few different sets of keys, but we have found that often a key from another bike will work.  For instance, the key from my Son's 82 XS 400 was the same as the 84 FJ, which was the same as another 84 FJ tank.  Possibly a wrecker might have a bunch of keys you could try?

Maybe it's "the same key" or more likely, it's worn tumblers in the lock, allowing 'similar keys' to be used.  A good thought though, a similar key from another Yamaha may just work.

Probably this, IMO.

I found out by accident that the key to my brand-new ignition switch will also work the gas cap and seat lock on my '89.

Typically the locks sets are not very worn.  None of these bikes have over 70,000 KMs and the XS 400s had less than 10,000.  Up here in the great white north they just do not get much use.  Next rally it would be an interesting exercise to see how many keys are interchangable.
