The 30 is a pin-tumbler padlock made by American Lock. This is one of the cheaper padlocks American Lock makes. It contains both serrated security pins for both key and driver pins.

The series 30 padlock is a standard pin tumbler lock which, though it sometimes has room for a 6th pin stack, comes pinned in 5 chambers. The bottom pins come in both serrated and plain, and the top pins come as spooled, spoorated, and serrated top pins. When all of the pins are lifted to the shear line by the key the plug can turn clockwise.

This removal of the rivet should drop off the bottom plug retainer allowing the plug to be removed (This cannot be replaced after it has been done). After the plug is out the same standard disasembly applies:
