How to Properly Maintain and Care for Lock to Extend its Lifespan?

Daily Cleaning and Lubrication

1. Regular Dust Removal: Clean the lock body casing every six months to one year to prevent dust and dirt from entering the internal mechanical structure.

2. Lubrication of Key Parts: Apply graphite powder or special grease (avoid liquid grease) to the keyhole, pin tumbler springs, and transmission gears to ensure smooth operation.

3. Avoid Oil: Never use cooking oil or other liquid lubricants, as these may cause the springs to stick and jam.

Reference: Lock maintenance guidelines indicate that regularly adding graphite powder to the keyhole for lubrication can prevent key insertion and removal difficulties; it is also recommended to check and apply lubricant to the transmission parts annually.

Inspection and Adjustment

1. Check Screw Tightness: After each use or during seasonal changes, check if the lock body screws are loose and retighten them if necessary.

2. Door Leaf and Lock Tongue Fit: Ensure the gap between the door and the door frame is between 1.0mm and 2.0mm to prevent jamming due to temperature changes.

3. Key Usage Tips: When closing the door, grasp the handle and fully rotate the bolt into the lock body before releasing. Avoid slamming the door. If you feel resistance when opening the door, gently push it to help overcome the spring force of the sealing strip.

Corrosion and Moisture Prevention Measures

1. Keep Dry: Locks should be installed in well-ventilated areas, away from direct rain to prevent metal corrosion.

2. Anti-corrosion Coating: For stainless steel or carbon steel lock bodies, regularly check the integrity of the surface coating and touch up any peeling paint promptly.

3. Dust and Insect Prevention: Use dust covers or sealant around the lock body to prevent dust and insects from entering the internal mechanical structure.

Professional Maintenance and Service

1. Annual Professional Inspection: It is recommended to have a comprehensive inspection conducted annually by a professional lock repair organization, including the wear and tear of key components such as internal springs, pins, and bolts.

2. Replace Wear Parts: Lock cylinders, springs, and other wear parts should be replaced after 3-5 years of use, depending on the frequency of use, to ensure security.

3. Technical Support: If abnormal noise, jamming, or key breakage occurs, please contact the manufacturer or authorized service center for diagnosis and repair in a timely manner to avoid further damage caused by self-disassembly.
