How To Spell Any 4-Letter Word in a Word Lock

“So, I’m a gamemaster and I made a bet with my boss that I could find a 4-letter word lock that we could spell ‘SWAN’ with. I’m struggling!!! Any chance you could help me out? I’ll buy multiple locks and trade the gears if needed. Thank you!!”

This is a fun little problem that you have.

There isn’t a lock on the market that can solve this problem for you, but as you alluded to in your question, there are two locks that can combine to solve the problem.

The Problem

So the issue is that “W” is a rare second letter in English and therefore not included in the second disk on the various word locks with fixed disks.

A 5 disk alphanumeric combination lock.

This leaves you with the customizable Master Lock 1534D 5-digit letter lock… but that’s a problem because it has 5 disks, not 4. Master Lock doesn’t sell a 4-disk letter lock variant.

The Solution

The good news is that there is a solution.

A 4 digit number lock.

The Master Lock 1523D 4-digit number lock uses disks that are functionally identical to the letter disks of the aforementioned Master Lock 1534D 5-digit letter lock.

If you purchase both locks, and swap the disks, you can put in any 4-letter disks you want, in any order, onto the smaller lock. There you have a 4-digit word lock with the combination “SWAN.”

  1. Master Lock used to make a 4-letter variant of the 1534D lock with the interchangeable dials. I’ve seen them in play, but I can’t find any reference or product numbers. This Amazon link shows it as part of a 16-pack, but it has the 1534D part number.

    Another option: there’s a Thingiverse project for making custom wheels for the 1534D. I imagine if that’s your thing (pun intended) you could make one with “blank” as an option.
