Any fix? I have a copper mod. Few days ago the lock switch siezed as well as the bottom cap. Managed to twistt hard enough to fix the lock switch. Now today, was tring to fix bottom cap, and lock switch siezed as well. Don't wanna have to buy another one and trash this. How do I fix. Keep in mind I live in Japan, don't. Necessarily have access to common brands u might have in ur home hardware store
