Genuine Start/Stop Engine Switch for Mazda 2, Mazda 3, CX-5 2017–2024, BJS7663S0 is an important part of Mazda's smart start system. This product allows the driver to start or stop the engine with the push of a button, completely replacing the traditional mechanical key and bringing convenience and a modern feel to everyday use.
In addition to the starting function, the Start/Stop switch also serves as the signal link between the smart key and the engine control unit (ECU), ensuring the vehicle only starts when it receives the correct valid signal, helping improve anti-theft protection and vehicle safety.
With long-term use, the Start/Stop switch may experience unresponsive buttons, slow response, or no signal due to worn internal contacts or electrical circuit faults. When this happens, the vehicle may be difficult to start, require repeated presses, or fail to start.
The BJS7663S0 product is manufactured to Mazda's genuine standards, ensuring high sensitivity, good durability, and stable operation in a variety of environmental conditions. This part is compatible with Mazda 2, Mazda 3 and CX-5 models from 2017–2024, with a direct-fit installation and no modification required.
