This is a smart key for a Toyota Harrier. It is likely that initialization and re-registration at a dealer will be required. Please note that I am not an expert, and therefore I cannot assume any responsibility for this smart key. I also cannot answer any questions regarding it. Operation has been confirmed, and it has been verified that there are no problems with the battery, circuit board, etc. Please consider purchasing only if you understand that this is a no-claims, no-returns sale. Thank you for viewing.
