I have read the thread with some interest. Being a Swede, living in this
Godforsaken country where the cars are made, I often experience lock problems
due to the massive amount of salt used on the skid-roads we have here
wintertime. Salt and dirt clogs up the locks effectively. The remedy is in two
stages: 1/ Lock cleaner and 2/ Lock lubricant. Now, I have no experience of what
WD40 is, over here we have an excellent lock manufacturer named ASSA-Abloy
issuing their own sprays to do the job. And it never fails. So my advise is to
either get a) something to dissolve the goey stuff clogging your lock and 2) a
lubricant that is not sensitive to moist or great temperature variations.
However I would advise against using any Mo-sprays.
The other alternative is to unmount the lock cylinders and clean them i
kerosene, diesel-fuel or equivalent and then lubricate with heavy grease.
However, doing this will require yearly makeover I'm afraid.
Cheers / Johan
