How to Program a Keyless Entry for Adiamante
- 1). Locate the Data Port underneath the steering column in your Mitsubishi Diamante. Note that the Data Port should have two rows of eight connectors. Make sure that there are metal contact pins in the "1" and "4" terminals of the first row.
- 2). Connect the "1" and "4" Data Port connectors with a 22-gauge jumper wire. Leave the jumper wire in place during the keyless entry programming process.
- 3). Insert your key into the ignition cylinder of the Diamante and quickly toggle it between the "Off" and "Acc" ignition positions in this order: "Acc," "Off," "Acc," "Off," "Acc," "Off." Complete this step within 10 seconds of connecting the "1" and "4" Data Port connectors. Wait for the power locks to cycle automatically before proceeding.
- 4). Press the "Lock" button on the keyless entry remote three times in quick succession to program it to your Mitsubishi Diamante. Note that the doors will lock and unlock automatically if the programming process was successful.
- 5). Disconnect the jumper wire from the "1" and "4" connectors on the Data Port. Remove the key from the ignition cylinder.
