Can Lubricating Oil Be Added to Car Keyholes?

[ReeseMarie]

It is advised not to add lubricating oil to the keyhole. Below are relevant details: Lubricating Grease: Since the lock cylinder requires a certain amount of lubricating grease during the manufacturing process, it is important to keep the key surface clean to prevent dust from being carried into the lock cylinder, especially for new car owners. Preventing Foreign Objects: When using the key to unlock, check for any foreign objects inside or around the lock cylinder hole to avoid damage. Door Locks: Regularly inspect vehicle door locks every 6 to 12 months based on usage frequency and wear. Since door locks are not sealed, they are significantly affected by external environments; sand erosion and temperature changes can degrade the performance of the lubricating grease, impacting the lock's functionality.
