How do I open a lock on a tool cabinet to which the keys have been lost?

I have a large rolling Snap-on tool chest with a locked roll down cover, that belonged to my Dad who is now deceased. Tried dosens of his keys to open it with no fit. I don't want to spend the money to have a locksmith open it. I don't care if the lock is broken, I just want to open it and use it for my tools. I am in need of instructions on how to open the lock.

1. When I lost the keys to my Tool chest I just took a 1/4 inch drill bit and drilled it out then followed that with a 1/2 inch and the lock assembly fell right off and I was able to open it.
2. Drill out the lock cylinder.
