What are these locks?

[maverickfhs]

So I bought a motorcycle and it came with these locks, which I have no idea.

One 'Master' one has no key, while other one has a key inside it, has some inscription and writings on it too, i-e a manufacturer. Manufacturer seems to be making utility meter locks.

So are both of these locks usable on a motorcycle(like a disc or something) or absolutely not? Just because then I'll get the key made or something of that sort

Thanks for any help and input

The lock in the third pic is a trailer tongue lock. I've never seen whatever that is in the other pics though... Now you've gotten me curious lol.

Those are used by utilities to lock the curb gas or water valve closed when the service is cut off. The same "key" fits all of them. It may work to keep your motorcycle from being stolen by someone who doesn't work for the gas company.
