Maintenance and Care
To ensure the longevity and proper function of your replacement key and padlock:
- Keep Clean: Keep the key clean and free from dirt, debris, or corrosive substances.
- Avoid Bending: Do not attempt to bend or modify the key, as this can damage it and render it unusable.
- Lubrication: If the padlock mechanism becomes stiff, apply a small amount of graphite lubricant to the keyway, not oil-based lubricants.
- Storage: Store the key in a safe, dry place to prevent loss or damage.
Troubleshooting
If you encounter issues with your replacement key, consider the following:
- Key Does Not Insert Fully:
- Check for obstructions in the padlock's keyway.
- Ensure the key is oriented correctly.
- Key Inserts but Does Not Turn:
- Verify that the lock code on your key matches the required code for your padlock (1448).
- The padlock mechanism might be stiff or corroded. Try applying graphite lubricant.
- Ensure the padlock shackle is not under tension, which can prevent the lock from turning.
- Key Turns but Padlock Does Not Open:
- This may indicate an internal issue with the padlock mechanism.
- Confirm the key is fully inserted and turned completely.
