Collapsible baton jammed?

Hey. I have a collapsible baton that the last piece is jammed. Ive tried wd40, silicone spray, a hammer nothing worked. Any ideas

it's likely dead. heating the outside piece while cooling the inside one is probably a long shot

Jammed extended, or jammed collapsed? Either way, remove the end cap, disassemble it, clean it, and lubricate it with a wax- based bike chain lube.
