Maintenance

• Lubrication: Periodically (e.g., every 3-6 months, or more frequently in harsh conditions), apply a small amount of lock lubricant (e.g., graphite-based or silicone-free spray) into the keyhole and the locking mechanism. This helps maintain smooth operation and prevents corrosion.
• Cleaning: Wipe the chain and its coating with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the synthetic fiber coating.
• Key Care: Do not force the key if it feels stiff. Ensure the key is fully inserted and the lock cylinder is clean. Avoid using damaged or bent keys.

Troubleshooting

• Key is Stiff or Won't Turn:
  • Ensure the key is fully inserted.
  • Apply lock lubricant to the keyhole and try again.
  • Check if the key is bent or damaged. Use a spare key if available.
• Lock Mechanism is Stuck:
  • Ensure the chain is not under tension when attempting to lock or unlock.
  • Clean any visible dirt or debris from the locking mechanism.
  • Apply lock lubricant.
