Resettable brass combination padlock

A four-dial brass padlock with a hardened steel shackle that opens with a user-set code. The combination is changed instantly using the supplied change key without tools. Up to 10,000 different codes can be programmed. The dial sits on the bottom of the lock body.

Indoor, low-security uses

Suitable for lockers, toolboxes, gym bags or garden sheds where a key-free lock is convenient. Not appropriate for high-value assets, outdoor gates exposed to attack tools or any application requiring a certified security rating. Buyers who need a shrouded shackle or a key override should look elsewhere.

10,000 possible combinations

The four dials provide exactly 10,000 unique codes, which is the sole measure of the lock's combination space. A higher or lower figure would indicate a different dial count, so this number confirms the product you are viewing.

Questions about this item

How does the brass body and hardened steel shackle hold up to daily outdoor exposure?

The solid brass body resists corrosion while the hardened steel shackle withstands cutting and sawing attempts, so the lock remains reliable through rain, temperature swings and constant handling.

What do I need to change the combination on the 175D?

The exclusive positive-action change key included with the lock is the only tool required; insert it, turn, set your new four-digit code and remove the key.

Can I use the same 10000-code system on an older Master Lock I already own?

Only if that older model also accepts the Master Lock change key and supports a four-digit resettable combination; otherwise the 175D operates independently with its own code.
