Master Lock 7045KA Padlock Keyed Alike

The Master Lock 7045KA is a rectangular padlock designed for users who need multiple locks operated by a single key. Its keyed-alike configuration simplifies access management for gates, sheds or storage units. The steel body and boron shackle provide a high-security mechanical barrier. This lock suits property owners wanting consistent keying across several entry points.

Sustained outdoor exposure and physical attack

The steel body resists deformation while the boron shackle withstands cutting and sawing attempts over time. A 5-pin cylinder with the Master K6000 keyway resists picking and bumping during prolonged targeting. The lock is not weather resistant, so moisture and corrosion may affect long-term reliability in exposed locations. Rekeyable construction allows the cylinder to be serviced without replacing the whole unit.

Rectangular body with partially hidden shackle

The rectangular body measures 2 5/16 in high by 1 3/4 in wide by 1 in thick, leaving minimal shackle exposure to bolt cutters. Shackle dimensions are 5/16 in diameter, 1 3/16 in height and 29/32 in width. The lock opens only with key number 11G304 and requires no control key registration. Buyers needing a weather-resistant finish or a different keyway should consider other options.

Questions about this item

How does the 5-pin cylinder behave when the padlock sits outside all day?

The 5-pin Master K6000 cylinder is mechanical, so temperature swings do not affect operation; no batteries or electronics are inside to fail in heat or cold.

What must I already have to open the 7045KA padlock?

You need the matching key cut to code 11G304; the lock is keyed alike and ships with two keys, so no additional tools or codes are required.

Will the 7045KA work with my existing Master Lock keys cut to the K6000 keyway?

Yes — the padlock uses the Master K6000 keyway, so any key cut to that keyway and the same alike code will operate it.
