Transponder Key Sub Transmitter

About this product

The Transponder Key Sub Transmitter (#89786-21020) is an integral part of Toyota's Lock Cylinder Set system. It primarily serves as a security component, sending a unique code to the vehicle's engine control unit (ECU) to permit ignition. Its operation is crucial in ensuring the car is only accessible by the rightful owner. This component, like any other, may deteriorate over time. If it becomes old or non-operational, the vehicle may fail to recognize the transmitted code, preventing ignition and potentially stranding the driver. Therefore, keeping this part in optimal condition is key to maintaining the overall efficiency and safety of your Toyota vehicle. This part, as with all Toyota auto parts, offers maximum vehicle compatibility when it's a genuine part and is supported by Toyota's authentic parts warranty. Genuine parts deliver superior quality and reliability, providing peace of mind for Toyota owners. Remember, when it comes to maintaining your vehicle, every part plays a critical role. So, keep it genuine, keep it Toyota.
