What to Do When a Motorcycle Hexagonal Lock Won't Open?

Remove the entire cover from under the lock, then open it like a regular lock. The fixing screw for this lock cover is located slightly below the lock cover. Drive the motorcycle to a repair shop and ask for help to open it directly.
I often encounter the issue of a hexagonal lock jamming when riding a motorcycle. First, don’t force the key or it might break. Start by spraying some WD-40 or sewing machine oil into the keyhole and wait five minutes to lubricate any rust. When inserting the key fully, try gently wiggling the handle left and right—sometimes the lock pins get stuck and need a little vibration to reset. If it won’t open after rain, using a hairdryer for three minutes to remove moisture usually works. Keep a rubber band at home; wrapping it around the key can increase grip when turning. These makeshift methods are good for emergencies, but if the lock core is visibly deformed, it’s best to call a professional locksmith to replace it—forcing it open yourself could damage the frame. As a side note, always cover the keyhole when parking outdoors to prevent rain exposure, and applying a drop of machine oil monthly for maintenance is crucial.
Veteran mechanic reveals: When a hexagonal lock won't turn, it's usually due to rusted tumbler springs inside. Use a thin wire hook to gently manipulate the tumblers inside the keyhole while spraying rust remover. Apply clever force when turning the handle - rotate clockwise halfway then suddenly reverse before continuing. Check for signs of forced entry on the lock body; deformation means you'll need to replace the entire lock assembly. Never force open transponder-equipped anti-theft locks - random poking may fry the ECU. As last resort, remove the body panel to detach and send the lock assembly for professional repair (requires special tools). For prevention: avoid hanging heavy objects on keychains to prevent deformation, and periodically test spare keys to maintain functionality. Keep rust prevention paste in your shop - it outlasts regular lubricating oil.
