Front downhill forks totally seized!...how to free up?

I don't have great knowledge about bikes but have a set of Zoom 620 Gordo Forks, they are totally stuck and wont compress what so ever...like their just rigid. I have popped the top caps off, nothing sits at the top to 'turn' anything but down inside the pipe there's like an allen screw sitting just midway where 2 parts join nearer the wheel (look slightly corroded)

How do I free it up? and dissmantle it, there seems to be no other screws to access inside the forks?

How on earth can I get to it the allen screw inside too lol

Any advice greatly appreciated thanks

Budget fork (mainly seen on bikes just above the BSO level), easiest option would be to scrap and replace, they were never really meant to be serviced.

tear it apart and clean and re oil things?

Typically on the bottom is where the long bolt heads are..

but I suspect ( it's not a $600 Rock Shox , so) dont get attached , you may have to toss it

Think the problem the OP has, is that they are unable to strip the fork down, going a quick search reveals no manuals online, can you supply one?

Also from looking at images of the fork, everything indicates they are an elastomer fork, oil has no business being anywhere near them.

Zoom Satori is just one of the many names of the Taiwan companies making Millions of them

just take it apart . , and Look ..no manual, insecure with out one?. cant figure out how to fix it?
may be a better idea go buy a new fork .

they are pretty cheap (certainly in lots of thousands selling to factories) , the retail path has higher costs by the time you hit retail .

want something to be serviceable and work better ? Remote lock out air oil adjustable. Those are even more expensive.. Sorry..

I attempted to dismantle a set of Zoom double-crown forks once with a view to using bits of them to make a stretch chopper. Some of them have allen-headed bolts you can undo through the holes in the bottoms of the legs. Some of them have rivets replacing those bolts, and can't be dissassembled (reversibly). I had the latter, so my chopper plan was shelved.

Also "Downhill" might be a good term for the intended use for those forks, but only because they ain't going up any hills at that weight!

I've took apart low end forks. Had a 1/4" socket drive handle with 2 or 3 extension pieces, and an adaptor to fit the allen bit. The fork legs from the fork crown, go into the lower legs, a few inches. The bolts in there are long, might be rusty even on working forks. there might be springs, but more likely rubber tubes in the lower legs. There will be plastic bush tubes at the top of the lower legs. These can be sloppy on brand new straight out of the box, forks. Theres unlikely to be any spares available.
