Thread: Disco door handle problem

from another thread relating to the rear door - use brake cleaner rather than WD40, as the oil in WD40 or similar will attract & hold dirt & grit & gum up the lock.

Also check the lock is not cracked. Compare it to your other doors there is what looks to be a plastic covering this was worn on mine compared to the second hand unit i fitted and it fixed the problem. My central locking didn't always work for that door which is also why i swapped it out.

Alex 110 is also correct my old one was full of dirt which is probably what started it.

You don't use 'sticky' oils such as WD40, RP7 etc on locks, as it will cause further problems with dust and dirt getting caught in the oil and stopping the mechanism from working. Hence the suggestion of brake cleaner. However, this removes all of the lubricant. If there has been a sticky oil used before, then the brake cleaner will assist in getting rid of this, so don't discount it.

A 'dry' lubricant, such as CRC Dry Glide will help remove any existing dirt on a lock, and provide a dry film for lubrication. It's a bit nicer to use than graphite dust for household and vehicle lock mechanisms, as it is an aerosol and provides great lubrication and water repellant properties.

BTW - WD40 was apparently the 40th attempt to create a water disperant. Hence the name. True or urban myth??
