What kind of lubricant should be used for car door handles?

[LailaLynn]

Car door handles should be lubricated with silicone grease. The car door lock system includes components such as the lock cylinder, lock body, inner handle, outer handle, inner locking mechanism, linkage rod, latch, and striker, many of which require lubrication. Specialized grease with specific properties should be used. The required properties are as follows: Longevity: The door lock mechanism is enclosed within the door and is difficult to maintain, so the grease should provide long-lasting, even lifetime lubrication. Low-temperature resistance: It must maintain lubrication at temperatures as low as -40 degrees Celsius, without solidifying or freezing in winter, which could affect the movement of the lock mechanism. Water resistance and anti-rust properties: Since the door is not a sealed structure, the grease should have good water resistance and prevent rust formation.
