I think you’re saying your bike has hex key security fixings instead of quick release hubs. I don’t know what make of hubs you have but on my Scott with Formula hubs they are 6mm so try that. Buy a set as they are always useful for other jobs and adjustments on the bike.
Are the keys you’ve been using metric?

BTW and welcome to the forum.

Sorry, I'm at a loss then. If you can't find a suitable hex wrench you will just have to take it to your local bike shop.
If you don't have one then it's case of removing the surrounding plastic casing and getting a vice grip on it.

That's not a hex bolt, it's pentagonal so you'll need to find (or buy) a set of pentagonal allen keys.

Good spot glasgi, completely missed that.
I guess that adds to the security.

I think they're sold as a complete set of security skewers, sometimes including the seat post clamp. If the newbie can get it off with mole grips it'll be easy to replace with a standard setup.
