My father has a storage locker and has lost both of his keys to get into it and cannot afford the 80$ charge for a locksmith. The lock looks just like the one pictured above that says "shop" and is of the brand name "Crown" if I remember correctly.

I was wondering if it is possible to somehow break the lock? Is it possible to drill through the keyhole or perhaps some other method... Any help would be great.
I've picked simple locks before but this is beyond me.
Thank you.
