What Are the Reasons for Volkswagen Remote Key Failure?
2 Answers
Volkswagen remote key failure may be caused by: 1. The car battery is dead, and the vehicle cannot receive signals; 2. There is high-power radio interference signals of the same frequency; 3. The antenna of the remote transmitter in the car has aged; 4. Some grease in the remote has become sticky, causing poor contact. Taking the 2020 Volkswagen Magotan as an example, it is a mid-size car with a body size of 4865mm in length, 1832mm in width, 1471mm in height, a wheelbase of 2871mm, and a body weight of 1445kg. The 2020 Volkswagen Magotan is equipped with a 1.4T inline 4-cylinder turbocharged engine, with a maximum horsepower of 150PS, a maximum torque of 250Nm, and a maximum power of 110kW.
I've been driving a Volkswagen for ten years and have encountered remote key failure several times. The most common cause is a depleted battery. The small round CR2032 battery loses voltage over time, weakening the signal, and replacing it yourself is cheap and easy. Another frequent issue is environmental interference, such as parking near shopping mall charging stations or WiFi devices, as electromagnetic waves can disrupt signal transmission. You can try moving away from these sources or using the manual key in the door handle to unlock and start the car. Another possibility is internal short-circuiting or button wear in the key—I once dropped my key, and the impact caused similar issues. To prevent problems, avoid stacking your key with your phone in a bag to prevent pressure, and regularly check the battery's health to save trouble. The car's receiving antenna is near the door frame, and if it gets wet or the wiring loosens, it can also affect responsiveness. In short, start with the simplest solutions: replace the battery or test in a different location. Only seek professional repair if necessary, saving time and ensuring driving convenience.
