Locks that work

Garnett, just out of interest, did you lube your previous lock from time to time?

Hopefully with graphite grease?
Hey there GAG2. Nope - I did nothing to it. And I read your recommendation. And I felt it getting more and more fouled up. And I left it in the rain at work overnight all winter.

I know. I know. I'm not criticising the lock, it's just not for a lazy git like me.
