• Programming Device: Some cars require a special device for key programming.

Step-by-Step Reprogramming Guide

Step 1: Enter Programming Mode

1. Insert Key: Insert the key into the ignition and turn it to the “On” position without starting the engine.

1. Insert New Key: Insert the new key into the ignition and turn it to the “On” position.

Step 3: Test All Keys

1. Test New Key: Attempt to start the car with the newly programmed key to ensure it works correctly.
