The maintenance of RV locks essentially involves five points: rust prevention, jam prevention, detachment prevention, freeze protection, and theft prevention. By performing the following eight steps as "monthly minor inspections and quarterly major inspections," the lifespan of the lockset can be doubled at least. Cleaning: Once a month. Surface: Use a neutral detergent and a soft cloth to wipe away dust and remove salt stains, avoiding acidic or strong alkaline detergents. Gaps: Use an old toothbrush or air blow to clean the dust and sand between the lock hole, handle, and door panel. Lubrication: Once every quarter
·Mechanical lock cylinder: Spray graphite powder or a dedicated lock cylinder lubricant for 1-2 seconds, insert the key and rotate it back and forth 5-6 times. Compression/lever-type panel lock: Apply silicone-based grease to the cam and spring to prevent jamming and abnormal noise. ·Unnecessary oils: Engine oil and butter can attract dust and block the core, so their use is strictly prohibited. Tightening: Once every quarter
Check all fixing screws with a screwdriver, especially after driving for 5000km, to prevent loosening due to vibration. Waterproofing: once every quarter
If the hatch lock has an O-ring, apply a small amount of silicone grease to maintain its elasticity and prevent rainwater and sediment from infiltrating. When washing the car in winter, avoid directing high-pressure water jets at the lock holes. For antifreeze protection: before winter
Drop 1-2 drops of antifreeze lubricant (-40℃ specification) into the lock hole to prevent the lock cylinder from freezing in the early morning. If it has frozen: use a warm key or a dedicated de-icing spray, and do not use fire to thaw it
