Weatherby cable lock spare key

[TNAndy]

I recently bought a Weatherby branded cable lock.  It came with two keys which have the Weatherby logo stamped into the metal.  I would very much like to have a third key.

I contacted Weatherby about buying a key blank (with the Weatherby logo).  Unfortunately, they do not sell them because Weatherby buys their locks from an outside supplier.  Worse, nobody I've found so far (hardware store; professional locksmith) has any key blanks that fit either.

I've actually got several cable locks with different brand logos that all use the same key blanks.  In other words, the keys fit into the grooves of the locks, but the different cuts (ie. notches, biting) prevent them from turning the cylinders.  I'm pretty sure all of these locks are made in China.  One of the keys (not the Weatherby) has the code "555" on it.

Does anyone have a suggestion on where I can buy spare keys for my Weatherby and other brand cable locks?

Thanks in advance.

The only thing I can think of would be to go see a locksmith. They should be able to figure it out. Hopefully you get a solution, God bless you!
