push start button Honda City

push start button in the Honda City is part of the Smart Key & Keyless Entry System, allowing the driver to start or stop the engine with a simple press instead of using a traditional key.
This feature is available in most modern Honda City models across variants in India.

When the driver presses the button (with clutch/brake), the system communicates with:
Engine Control Unit (ECU)
Immobilizer system
Body Control Module (BCM)
to ensure secure and smooth engine start.
The button is usually illuminated and mounted on the dashboard, designed for long life and frequent usage.
