Setting Your Combination Code
Your GRIFEMA GA1002 padlock comes with a factory default combination of 0-0-0-0. Follow these steps to set your personalized code:
- Ensure the padlock is open and set to the default code 0-0-0-0. Pull up the shackle.
- Rotate the shackle 90 degrees counter-clockwise (or clockwise, depending on the model) until it aligns with the code setting gap on the padlock body.
- Press the shackle down firmly until the tiny pin is fully inside the gap.
- While holding the shackle down, rotate it another 90 degrees in the same direction. The shackle should now be in a horizontal position, locked down.
- With the shackle held in this position, scroll the number dials to set your desired 4-digit combination. Choose a memorable code.
- Once your new code is set, turn the shackle back 90 degrees to its original upright position. Release the shackle; it should pop up.
- Scramble the dials to lock the padlock. Test your new combination to ensure it opens correctly before securing any valuables.
Important: Please remember your new combination. There is no master key or override function to reset the code if forgotten.

Maintenance
- Cleaning: Wipe the padlock with a soft, damp cloth to remove dirt and grime. Avoid harsh chemicals.
- Lubrication: For smooth operation, especially in outdoor environments, occasionally apply a small amount of graphite lubricant or silicone spray to the shackle mechanism and dials.
- Storage: Store the padlock in a dry place when not in use for extended periods to prevent corrosion.
Troubleshooting
- Padlock will not open:
- Ensure the correct combination is entered. Double-check each digit.
- Make sure the dials are perfectly aligned with the indicator marks.
- If the padlock feels stiff, apply a lubricant as described in the Maintenance section.
- Cannot set a new combination:
- Verify that the shackle is fully pressed down and rotated correctly into the setting position.
- Ensure the padlock was initially opened with the current (default or previous) combination.
- Forgotten Combination:
- Unfortunately, without the correct combination, the padlock cannot be opened or reset. It is crucial to record your combination in a secure, memorable location.
