How to Lubricate Gerda Door Locks: Tips for Drum & Insert Style Locks (10yrs old) - WD-40?

Hello, I have two locks, one drum and the other plain, insert, something in this pattern http://www.furgala.com.pl/uploads/images/2012/04/1422/wkladka.jpg

The question is, how do I smear it so they fall in? they are around 10 years old and when they put on or pull it out, they cut themselves and move them hard. Wd 40 will give or some other specialistic liquid?

If the key is not skewed, you should not lubricate the gerda liner collects more dirt dust, just blowing through with compressed air.
I do not recommend it - in the end you can try after blowing with dirt, slightly use Wd 40 and turn the key several times, and remove excess oil with compressed air.
After so many years, this is the cause of wear and tear when inserting the key, I recently exchanged the replacement pad.
The hinges themselves, after laceration, require periodic lubrication.

Hello, I used to buy, probably in the Casto * frame a special lubricant for cylinder locks, I do not remember the manufacturer, I think Abus ... it is a few centimeters high spray applicator, with a tube.

Proposes - Dry PTFE grease (Teflon).

Powdered graphite from a pencil can help. It applies to car inserts.
