One. Can the lock core of the anti-theft door be lubricated with machine oil?
No.
Lubricating the lock cylinder with machine oil provides a good short-term effect, but over time, the oil will attract dust, which can eventually block the lock cylinder, causing inconvenience.
Furthermore, if the application is during winter, using machine oil to lubricate the anti-theft door lock mechanism is not recommended, as the low temperatures in winter can cause the oil to solidify. Overfilling the lock mechanism with machine oil can prevent the key from rotating and even cause the key to get stuck, making it impossible to open the door.
What lubricant should be used for the locking mechanism of anti-theft doors?
1. Apply the specified smooth agent internally within the locking mechanism.
It is recommended to keep some specialized anti-theft lock core lubricants on hand for home use. These can typically be purchased at hardware stores and are very affordable and convenient to use. To use the lubricant, simply inject it into the anti-theft lock core and then roll the key back and forth inside. Please note that this lubricant is specifically designed for anti-theft lock cores and is not the same as machine oil, lubricating oil, or edible oil.
2、Apply graphite powder into the lock core groove.
Graphite powder provides a smooth metallic finish. You may often find black, gray residue on newly purchased locks, which is residue left behind when the vendor inserts graphite powder into the lock mechanism. If you don't have graphite powder, you can use a pencil, as the primary material for pencil leads is graphite. Use a knife to shave off some graphite powder from the pencil lead and then apply the powder into the lock mechanism to enable smooth operation.
3. Apply rust remover
The primary component of the rust remover is hydrochloric acid, which can remove rust from metal surfaces. Apply the rust remover directly to the lock core of the security door, wait for a while, and then insert the key to roll it, which can open the stuck security door lock.
