How the Systems Work: A Technical Overview

Both keyless systems rely on a radio frequency identification (RFID) and low-frequency (LF) communication between the vehicle and the key fob. When the driver approaches the Golf 7, the car emits a low-frequency signal (typically 125 kHz) that activates the fob. The fob then responds with a unique encrypted code via radio frequency (315 MHz or 433.92 MHz), allowing the car to verify authenticity and unlock the doors.

For engine start, the car checks that the fob is inside the cabin using internal LF antennas. Once confirmed, pressing the start button initiates the ignition sequence.

Security Tip: To prevent relay attacks on passive keyless systems, store your key fob in a signal-blocking Faraday pouch or metal container when not in use, especially at home or in high-theft areas.

Pro Tip: If your key fob battery is low, place it directly against the start button or inside the cup holder (some models have backup antennas) to start the car in emergency situations.
