Brass Padlock KA 404 6000

This Master Lock brass padlock is keyed alike to number 404 on the K6000 keyway. It suits users who need several locks opened by a single key for gates, sheds or storage units. The laminated brass body and steel shackle resist weather exposure. High-security rating and four-pin cylinder deter casual tampering.

Keyed-Alike Convenience

The keyed-alike configuration means one key operates every lock in the set, reducing the number of keys carried. No control-key registration is required, so additional locks can be added later without paperwork. The lock is not rekeyable and has no interchangeable core, so the cylinder cannot be changed if a key is lost. Buyers who need individual keying or master-key systems should choose a different model.

Four-Pin Cylinder Limits

The four-pin K6000 cylinder provides basic pick resistance but is not rated for high-security installations requiring advanced cylinder protection. The 5/16 inch steel shackle offers standard cut resistance; users needing hardened shackles or shrouded designs must look elsewhere. California Proposition 65 warnings apply due to chemicals in the brass body. The lock cannot be rekeyed, so a compromised key means replacing the entire unit.

Highlights

  • Solid brass body resists corrosion
  • Four-pin cylinder provides pick resistance
  • Keyed alike to 404 simplifies access
  • Laminated finish adds weather protection
  • High-security rating deters forced entry

Questions about this item

Will the 4-pin cylinder need rekeying or core replacement over time?

The cylinder is not rekeyable and has no interchangeable core, so the entire padlock must be replaced if the keying needs to change.

What part reaches its limit first when the padlock is used daily outdoors?

The 5/16 in steel shackle is the primary wear point under repeated tension and exposure.

How much heat or noise does the brass body produce in constant outdoor use?

A passive brass body generates no heat and makes no noise during normal operation.
