Step-by-Step Programming Instructions:

Enter Your Vehicle: Sit in the driver’s seat with all doors closed and windows rolled up.
Insert and Remove Key: Insert your working key fob into the ignition and remove it. Repeat this process six times within ten seconds. Your hazard lights should flash, signaling that the programming mode is activated.

After a few seconds, you’ll hear a beep and the security light will turn off, indicating successful programming. Repeat this step for each additional key fob, including the new one.
Exit Programming Mode: Remove the key fob, open and close the driver’s side door, and then insert the key fob back into the ignition.
Test Your Key Fobs: Check if the newly programmed key fob functions correctly by locking and unlocking the doors and starting the engine.
