The shell screws are located on both sides of the casing. The lock wires are at the bottom of the lock, usually consisting of four wires: red, black, green, and black-white. Be careful when cutting to avoid causing the positive and negative poles to touch. When the colored wire and the red wire touch, sparks may occur, which is a normal phenomenon. After connecting them, wrap them with black tape, and then you can start the motorcycle to go and replace the lock.

A broken motorcycle lock cylinder is indeed quite frustrating. I rode motorcycles for over ten years and encountered this issue several times, mostly due to rust or wear in the keyhole. Initially, I tried spraying some lubricant into the keyhole, which sometimes solved the problem. However, never use engine oil as it attracts more dust—graphite powder is more effective. If the lock cylinder is completely jammed, it might be due to a broken internal spring or metal fatigue. Trying to force it open yourself could cause more damage. In such cases, it's best to visit a professional repair shop where they can replace the entire lock cylinder, usually for a reasonable price—just a few hundred yuan. Neglecting repairs can be dangerous, especially if the bike suddenly fails to start while riding, leaving you stranded on the road. For maintenance, I recommend regularly checking the keyhole to prevent water or debris from entering and applying lubricant periodically to avoid many issues.

As a frequent motorcycle rider, I have to say don't panic when facing a damaged lock cylinder. First, do some simple troubleshooting: check if the key can turn halfway. If it can but gets stuck, it might be due to dirt blockage - try blowing it out with compressed air or gently cleaning with a soft brush. If it's completely immovable, the internal mechanism might be broken, requiring professional attention. I once tried poking around with small tools myself, only to make it worse - ended up having to pay for a replacement anyway. Repair shops can usually fix this quickly, taking about an hour on average, costing around 100-200 yuan. Much better than putting it off. Regular maintenance helps - use a cover when parked to keep the keyhole dry, and such issues become rare. Safe riding is crucial; starting problems can lead to unimaginable consequences, so don't take risks by delaying repairs until something bad happens.

From my experience, a faulty lock cylinder is usually caused by long-term use or environmental factors, such as rainwater corrosion or key wear. As soon as you notice the key won't turn, I recommend addressing it immediately—don't rush to force it, as this can damage more components. You can start by spraying some lock-specific lubricant and waiting a few minutes to see if it loosens. If that doesn't work, quickly contact a professional shop for a replacement. Spending a little money to fix it ensures safe riding.
