I can't lock my Overlander from the outside. Its a Bargman L100 I believe (round knobs both sides, knurled edges of knob, square backing plate). I've squirted all kinds of lube, liquid wrench etc and no luck. I fiddled with loosening and tightening the mechanism, no luck there either. I need to dive deeper.
It locks fine from the inside, and I can unlock it from the outside, but now I can't really lock it from the outside. (Used to be tough, now impossible).
Any suggestions? Could it just be the cylinder? Do I need to rebuild? (Not looking forward to replacing with similar at ~$400 )
If necessary I am open to replacing the lock with something more contemporary/functional, but not willing to modify the door or frame etc. Suggestions here for Plan B would be helpful too.
