The 30 is a pin-tumbler padlock made by American Lock. This is one of the cheaper padlocks American Lock makes. It contains not only security top pins, but security bottom pins as well.

Principles of operation

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. The 30 series often has high tension on the plug and can require more force than normal to turn the plug once it has been picked open.

Disassembly instructions

Once the padlock is opened, the shackle can be turned and a rivet can be hammered out of the lock. 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:

1. Remove the cam or C-clip.
2. Insert the key and turn the plug 45-90 degrees.
3. Withdraw the plug from the cylinder. (A plug follower is recommended)

OR

1. Remove the chamber casings and take out each pin-stack individually
2. Remove the cam or C-clip.
3. Withdraw the plug from the cylinder.
