3. Setup and Duplication

The JMA ME-2.P is a high-security, laser-cut key blank. Due to its specialized design, standard key cutting machines are not suitable for duplication. A specialized high security key duplicating machine is required to accurately cut this key blank.

It is recommended to seek professional assistance from a qualified locksmith equipped with the necessary machinery for key duplication. Attempting to cut this key with improper equipment may result in damage to the key blank or an unusable key.

5. Maintenance

To ensure the longevity and proper function of your JMA ME-2.P key blank, once cut, follow these general maintenance guidelines:

• Keep the key clean and free from dirt, debris, or corrosive substances.
• Avoid subjecting the key to excessive force or bending, which can damage the blade.
• Store the key in a safe place to prevent loss or damage.

6. Troubleshooting

If your duplicated JMA ME-2.P key does not function correctly, consider the following:

• Key Does Not Turn in Lock: This often indicates an inaccurate cut. Return to the locksmith who duplicated the key for inspection and recutting. Ensure they used a high-security laser-cutting machine.
• Key Does Not Start Vehicle (but turns ignition): If the key turns the ignition but the vehicle does not start, it is likely due to the absence of a transponder chip. This key blank does not support transponder functions. Your vehicle may require a key with an integrated transponder for engine immobilization systems.
• Physical Damage: Inspect the key for any bends, cracks, or wear that might prevent it from fitting or turning smoothly.
