Choose these locks if you need locks that each open with a different key. All locks have random key numbers.

Locks with a dual-locking shackle prevent attempts to force them open from prying, shimming, or tapping because both ends of the shackle lock inside the padlock body.

Aluminum-body locks are stronger and more corrosion resistant than zinc-body locks. They also resist corrosion better than steel-body locks, but they’re not as strong.

Hardened steel shackles are stronger than steel shackles.Those that are copper-nickel-chrome plated have an added layer of corrosion resistance and strength. Pin-tumbler key locking mechanisms are the most difficult to pick. The more pins a lock has, the harder it is to pick.
