Keyed-alike padlock for multi-lock access

This Master Lock padlock uses a keyed-alike system so a single key opens every lock in the set. It suits facilities managers, landlords or homeowners who need identical keys across several entry points without carrying a bulky key ring.

Simple installation with one key to manage

No tools are required beyond the key itself; the lock fits standard hasps and chains. The only common issue is losing the single key that controls every padlock, which would require replacing the entire set.

Four-pin cylinder with fixed key number X2420

The lock uses a four-pin Master K1 keyway and is cut to key number X2420, so every unit ordered under this code works with the same key. Buyers who need unique keys per lock should choose a different model.

Questions about this item

How can I confirm the padlock is operating correctly after I install it?

Insert the X2420 key and turn; the shackle should release smoothly and the four-pin cylinder should engage without binding.

What comes with the padlock and what must I purchase separately?

The padlock itself is supplied with two keys cut to X2420; no additional hardware or cylinders are included.

Which keyed-alike version should I choose if I need multiple locks to share one key?

Select the 1KA model — every unit in that series opens with the same X2420 key.
