What type of Keys do FCI MS-2s use?

I got an FCI MS-2 for my Birthday but unfortunately it came with the wrong key.

Does anyone know what type of key the FCI MS-2 uses?

According to a key database I maintain (which I made by going through the keys I have & seeing what they’d fit) the FCI MS-series of manual stations (both the MS-2 & the MS-6) takes the PK625 key.

The ms-2 takes the pk625 key, there’s many for sale on eBay

So just an update it turns out there was nothing wrong with the key. It was just a custom cut Key that was a replica of the original FCI Key. And the reason it didn’t work I’m currently unsure of, but either way, with an activation and a reset, I was able to make the Key work as it should.

Thanks for the help with the Key Type btw. Even if I didn’t need an FCI Key.
