How to Program a 2004 Mitsubishi Eclipse Ignition Chip Key Transponder

Step by Step How to Programming Instructions:

This vehicle requires two working programmed keys to add a key to the system.

1. Obtain a new key cut by a locksmith or qualified person.
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 immobilizer 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. You must then start over from the beginning again.
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 one or no keys for this vehicle, it is not onboard programmable and requires a qualified professional to program the ignition key.

If you need a locksmith:
1. Locate an automotive locksmith in your area using LocateALocksmith.com.
2. If your vehicle is still mobile, it may save you money by driving to the locksmith instead of having them come to you.
3. The locksmith will then hook up specialized computer equipment to your vehicle in order to program the ignition transponder chip key.
