Master Lock 5 Pin High Security Padlock Keyed Different

SKU CH-BK01-S5ZMN

High-security padlock with a 5-pin Master K6000 keyway and boron shackle, keyed differently for individual access

  • Five-pin cylinder resists picking with Master K6000 keyway
  • Boron-alloy shackle withstands cutting attacks
  • Laminated steel body adds layered strength
  • Rekeyable design allows cylinder changes later
  • Keyed-different convenience for single-lock use

5-Pin High-Security Padlock

This Master Lock padlock uses a 5-pin cylinder with the Master K6000 keyway to resist picking and bumping. The boron shackle and laminated steel body provide strong physical resistance against cutting and prying. It is sold keyed different, so each lock opens with its own unique key. The lock is rekeyable for future changes.

For securing gates, sheds and storage units

Homeowners and small-business owners who need a single, pick-resistant padlock for outdoor or indoor use will find this model suitable. Buyers who require multiple locks that open with the same key should look at keyed-alike options instead. Users needing a weather-resistant finish for harsh coastal or industrial environments should consider other models.

Check shackle clearance and keyway compatibility

Measure the hasp or chain link to confirm the 3/8 in shackle diameter and 3/4 in internal height will fit through the opening. Verify the 7/8 in shackle width clears the mounting hardware on your gate or locker. Ensure any existing Master Lock keys you plan to use match the K6000 keyway before ordering.

Questions about this item

Does this padlock need any extra parts to lock a standard hasp or chain?

The 3/8 in boron shackle fits directly through common hasps and chain links, so no additional hardware is required.

Can I keep using my existing Master K6000 keys with this lock?

Each unit is keyed different, so your current K6000 keys will not operate this padlock; you will receive two new keys cut to this lock only.

How can I confirm the lock is functioning correctly after I install it?

Insert the supplied key, turn it fully and verify the shackle releases smoothly; then close the shackle, remove the key and test that the lock stays secured.
