Default Protecting the Lock actuator from frost

Guys

OK, this is an odd time of the year to be thinking about this however I had some major issues last winter and, as the door cards are off at the moment, I thought I'd try some preventative maintenence to avoid the same issues this coming winter.

I've had look around and the general consensus is to spray the lock mechanism liberally with grease via the inner door cavity, however I can't see how this would be that effective as almost all of the exposed parts that will get the grease are plastic. The metal inner workings are hidden by either the plastic or are inaccesable due to them being screwed to the door at the latch side.

Would it be better to spray the grease through the actual latch side?

Thoughts guys??

Paul

There is also the problem of moisture in the lock barrel itself. Consult a locksmith, there are special "sprays" designed for lubricating those parts. OIl, greases etc must not be used.

Had this problem last winter with bouncing doors when I tried to lock them, the car was a newly bought one and after my experiences with my old one, knew there was only one solution: off with the door cards and spray light oil (I used ATF) soaking all the latches and mechanism. I have my own compressor. Success, never came back.

I don't think it's normally possible to lubricate the motors as everything is well hidden, but soaking everything from the inside does help and if it helps during our -20c winters it should be more than enough in mere frosty UK.

I'd not considered the actual barrel as so far the drivers door hasn't posed a problem but that a good point and I'll get some lock lubricant as well.

And if a good dose of ATF protects against Swedish winters then that sound like its actually fine to just cover everything anyway.

Thanks for the responses guys, I'll add the items to my shopping list for my visit to Euro Car Parts!!

For the mechanical parts of a lock mechanism, I was told that Graphite Powder is the correct thing to use. I'm not sure about its interaction with the electrical parts though.

Graphite powder is the correct method for most locks (no problems with electrics on our lock barrels), however if it is a moisture problem then that will not of necessity fix it, hence my suggestion of the available sprays from a locksmith.

Chase out the moisture with WD40 and then slather everything with silicone grease. I've never had a problem with bouncing doors in the winter since doing that.

ACF50 spray and grease. Not cheap but works on aircraft carriers and is suitable for electrics too.
