Most likely it needs the keyless works to be reset.
The exact steps vary depending on the movement but are similar. Hands, dial, and datewheel all have to be removed.

2824/36 Keyless Reset Tutorial
Id been meaning to do this for I guess years now but recent posts got me motivated to do it. The 2824 and 36 share the same keyless parts, so the reset is really similar. This is the exploded diagram of the 2824 keyless parts. They are the same except for the minute train bridge, which looks diff...

You may have stripped your crown tube threads or your crown threads. Common issue with the VSF Seamasters.
Here's an option.

Was hoping I don’t have to rest the key less.
I just tried to rest a 2836 keyless on my noob submariner, but a little v shape spring kept flying, wine though 10 of them. Need to by more it’s a pain in the a$$!

Thanks Geanor, I’m hoping it’s the way to go!! Hopefully someone else that went through this issue before has an say fox for it!!
Until you are more experienced and confident in your skills, cover the movement with a piece of clear plastic wrap with a couple of holes for tools. It will keep feisty parts from going ballistic.
It may not be the keyless anyway because I’d expect issues you didn’t mention. However, if crown and stem are loose and/or do not click into place, if you can’t wind the mainspring, if you can’t advance the date, and/or if you can’t set the time, your keyless will need to be reset.
If the only problem is that the crown refuses to screw down, it is a threading issue. As @Geonor pointed out, it is a common problem with VSF Seamasters. If so, either the tube or the crown (or both) will need to be replaced and, if you are careful, you will not need to mess with the keyless.
I have one rep I almost never wear with pretty much the same issue: crown doesn’t screw down It’s not worth my while to try to get new parts for it. The same issue can pop up for a gen too. I have a Baume&Mercier with a very finicky crown. You have to angle it a certain way to get it to screw down. I suppose the crown or the tube is going. I just let it run since it’s a quartz and rarely mess with the crown.
Your crown screws inside the tube so it is a bit of a challenge to see if the threads are stripped. But replacement crowns for the Seamaster are often sold with tubes. Once you have a new crown and tube, you’ll be able to test the threads.
If the new crown screws firmly into the existing tube, there is no need to replace the tube. Just screw your stem from the old crown into the new crown and you’re golden.
If the tube needs replacing, use the tool @Karbon74 recommends to push the tube out. It usually comes out without a problem.
