Installation Guide

The low-frequency antenna has two functions:

1. It detects the additional matched key inside the vehicle to allow engine startup. If the key is not inside the car, the vehicle cannot start. Simply place the main front antenna anywhere inside the car, as it can detect keys within a 5-meter range.

2. It senses the additional matched key to enable automatic door unlocking when approaching the vehicle and automatic locking when leaving. For this function, mount Low-Frequency Antenna 1 on the Driver-side A-pillar, and Low-Frequency Antenna 2 on the Passenger-side A-pillar.
