How to Program a 2003 Mitsubishi Galant Ignition Chip Key Transponder

Step by Step How to Programming Instructions:

1. Obtain a new key cut by a locksmith or qualified individual.
2. Insert the first programmed key into the ignition and turn it to the ON position for 5 seconds, then turn it back to the OFF position and remove the key.
3. Insert the second programmed key into the ignition and turn it to the ON position until the immobilizer light is flashing (within 10 seconds). Then, turn the ignition back to the OFF position and remove the key. Note: If an error occurs while the immobilizer indicator light is flashing, the light will go out; otherwise, it should still be flashing.
4. Within 30 seconds of the flashing indicator light, insert the new key into the ignition and turn it to the ON position. The immobilizer indicator light should stay solid for about 3 seconds when programming is complete. You can then turn the key back to the OFF position and remove it. Note: If an error occurs, the immobilizer indicator light will flash 3 times, and you must start over from the beginning.
5. The new key should now start the vehicle.
6. To program additional keys, repeat steps 1 through 5 for each additional key. If you have no keys for this vehicle, note that it is not onboard programmable and requires a qualified professional to program the ignition key.
