How to Program a 2005 Lincoln Navigator Ignition Chip Key Transponder
Step by Step How to Programming Instructions:
You can program up to eight keys for your vehicle, but only SecuriLock keys are compatible. To program a key yourself, you’ll need two previously programmed keys (ones that already start your vehicle) and the new unprogrammed key(s) ready for each step. Please read and understand the entire procedure before starting.
1. Insert the first previously programmed key into the ignition and turn it from OFF to ON (keep it in the ON position for at least one second but no more than 10 seconds).
2. Turn the ignition back to OFF to remove the first programmed key.
3. After three seconds but within 10 seconds of removing the first programmed key, insert the second previously programmed key into the ignition and turn it from OFF to ON (keep it in the ON position for at least one second but no more than 10 seconds).
4. Turn the ignition back to OFF to remove the second programmed key.
5. After three seconds but within 10 seconds of removing the second programmed key, insert the new unprogrammed key (new key/valet key) into the ignition and turn it from OFF to ON (keep it in the ON position for at least one second but no more than 10 seconds). This will program your new key to a programmed key.
6. To program additional new unprogrammed keys, repeat Steps 1 through 5. If successful, the new programmed key(s) will start the vehicle’s engine and operate the remote portion of the key.
