Anyone know of reputable uk / eu solar stores

So I’m looking for a solaredge optimizer key that I can use to disable the dc protection on the solaredge optimizers so that they can be used with any inverter.

The optimizers themselves are available locally but I can’t seem to find the key device anywhere so am thinking of ordering 1 from overseas but seeing as there are so many dodgy / scammy sites locally, I’m not sure if it’s the same elsewhere in the world.

So anyone know where I can get this.
