Alike-Keyed Padlock with Extended Shackle
This Master Lock padlock uses a 5-pin cylinder and a keyed-alike system so multiple locks open with the same key. It is built for outdoor gates, sheds and storage units where a single key simplifies access. The laminated steel body and boron-hardened steel shackle resist cutting and prying attempts. Weather-resistant construction protects the mechanism from rain and humidity.
Replacing Individual-Key Padlocks
Switching to this alike-keyed model removes the need to carry separate keys for every lock on a property. The change is worth it when several entry points are used by the same person or team and key management has become a hassle. Rekeyable cylinders let a locksmith alter the combination later if key control is lost. The extended shackle reaches through thicker hasps or chain links that standard shackles cannot clear.
Limits of the Keyed-Alike System
Every lock in the set opens with key number 10G010, so anyone who holds that key gains entry to all secured points. Lost keys cannot be blocked without rekeying or replacing every unit in the group. The 5-pin mechanism provides standard security but does not meet high-security ratings required for certain commercial insurance policies. Shackle dimensions are fixed and cannot be swapped for shorter or longer versions.

Questions about this item
Will the 5/16 in. shackle diameter fit my 3/8 in. chain links?
The shackle is 5/16 in. thick, which is smaller than a 3/8 in. opening, so it will pass through standard 3/8 in. chain links.
Do I need to remove the key before locking the shackle?
The key is non-removable while the padlock is open; you must push the shackle down to lock it, then turn the key to the locked position before withdrawing it.
How do I keep the laminated steel body weather resistant over time?
Apply a light silicone or PTFE spray into the keyway and shackle holes every few months to prevent moisture from corroding the internal pins and boron steel shackle.
