Common root cause: Dust, dirt buildup, or lack of lubrication in the cylinder.
Step-by-step solution: 1. Apply a small amount of dry lubricant specifically for locks (graphite powder or silicone spray) into the cylinder. 2. Insert and remove the key several times, gently turning to distribute the lubricant.
💡 Pro tip: Lubricate the cylinder every 3-6 months, especially if the lock is exposed to weather.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact the seller for warranty service if the lock exhibits a manufacturing defect, such as a cylinder that won't turn even after lubrication and alignment checks, or if the shackle has structural failure unrelated to cutting or impact. Severe corrosion issues within a short usage period, or mechanism defects preventing locking/unlocking without excessive force, also indicate a need to contact the seller for warranty service.
