Understanding Push Start Technology
Before we dive into the troubleshooting process, it’s essential to understand how push start technology works. Push start cars rely on a key fob to transmit a signal to the car’s computer, which then verifies the signal and allows the car to start. This signal is usually transmitted via radio frequency (RF) and is received by an antenna located in the car. The key fob contains a small computer chip that stores a unique code, which is matched with the code stored in the car’s computer. If the codes match, the car’s computer sends a signal to the engine control unit, allowing the car to start.
Key Fob Components
A key fob typically consists of several components, including:
A battery, which powers the key fob
A computer chip, which stores the unique code
A transmitter, which sends the signal to the car’s antenna
