Hi,

back yet again with another query.

My passanger door won't open from the inside and somtimes from the outside also. I had it at the garage 6 weeks ago and they fixed it but the same thing is happenning again. Has anyone any idea why (so I am fully informed before I bring it back to teh garage again)?

Also, at the same time the key fob red close button would not close the central locking. They fixed that and the it has also gone again? Any idea what this is (so I am fully informed before I bring it back to teh garage again)?

Many Thanks Chris

My driver's door had the same problem and WD40 on the door latch fixed it. It's worth a try my handle works like new now. Can't help with the key fob locking I'm afraid...

i have been told by a lock smith that it's better to use 3in1 oil as WD40 will tend to wash out the grease from the lock so will need re dosing more often. that goes for any locks or handles not just on cars
weather it is right or not i don't know but it certainty work on my locks.

I agree Fungus. Nice name!

Oil and grease are usually compatible. Grease and WD40 can cause a chemical change in grease formulation and a sticky sludge will occur in some instances. In the aircraft industry such practice is discouraged for that reason.

I try to use silicon oil or spray for locks. I`ve found it rather better for locks than WD for the above reasons. Basic thin oil works quite well as sludging is usually not a problem.

What does WD40 stand for? Wet Day 40. 40day life. After that the chemicals evaporate off.

Not a lot of people know that!
