Having recently returned from a 6 week trip in our Chic C-Line 150, I completed the full wash and clean and decided to lube the key locks on garage doors. Made the mistake of using ordinary oil and not graphite/PTFE based. Now keys jam in lock and barrels don't return to central point. My thoughts are springs in barrel are clogged/jammed or broken. Does anyone have experience of barrel strip and clean on FW series barrels or obtaining FW series replacement barrels to save additional keys just for garage locks. Hope someone can advise. Thanks in advance.
