I'm looking for a Mosler 302 change key

[98G]

I've worked on these locks before, and I was able to change the combination by disassembling the wheel pack and indexing the wheels that way. This one is different.

It's not marked 302, but I'm thinking that's what it is. It's out of a 1984 GSA container.

Here are some options I would consider.

1. buy the SLC-46 MRK-302 change key for $39.79 from MBA USA

2. buy the Keedex K-18 from this seller on ebay for $69.99 https://www.ebay.com/itm/326227371179 which you can use on other safe locks as well.

3. make your own from some metal stock that you can shape into a square shaft

4. use a small flat head screw driver to unlock the wheels one at a time shallowest to deepest, dial a new combo, and re-lock the wheels one at a time deepest to shallowest.

5. modify another safe change key to fit your 302
