Has anyone had a problem with the gas cap lock not turning? My buddy has a 2005 1800r and he can't get the cap off. The key won't turn at all. Pushing down on the cap doesn't help. We sprayed some liquid graphite and that didn't help. This has been going on for quite a while now and it always eventually opened. Today, no luck. Two different keys didn't help either. Is it time for a dealer/locksmith visit?
