What type of Bump Key would I use for a round lock like this?

Also I was trying to copy some original keys and the locksmith refused them just because they have numbers on them (and he said the size was weird).

I'm guessing it would use some type of master key one since they make a very similar product.

It's also possible maybe it won't work because these locks don't let you take the key out when it opens you have to close it before the key will be able to come out and you can only close it by turning the key.

Any advice?

I just found out the correct name is "Disc" not round.

It looks like they are mainly 4 and 5 pin tumblers, and the reason I am not sure if a bump key would work is because the key needs to turn all the way before u can take it out... anyone know?

If the key is right it would work.... if you are really good. Spool drivers and other types are found in a wide range of disk type locks to slow down picking. It doesn't help in bumping.

Wouldn't it always work if you're really good.
Bump first and ask questions later.

I have this type of old lock and tried once and I think its pretty tricky to bump that. I used same techniques many time but it worked sometimes and sometimes not. I think I am missing something.
