What Causes a Car Remote Key to Malfunction?

[DelJuniper]

Here are the reasons for Volkswagen remote key malfunction: 1. The remote key battery is depleted; replacing it with a new battery can resolve the issue. The internal batteries of the key come in different models, so pay attention to distinguish them when replacing. 2. Strong magnetic field interference in the surroundings affects the remote key's electronic signal communication. When the vehicle is parked in an environment with strong signal emitters, the electromagnetic field can penetrate through gaps and openings on the car body and affect related electronic components. 3. Internal damage to the remote key or damage to the signal receiver on the car body requires professional repair. When the unlock or lock button is pressed on the remote key, the key chip sends an encrypted signal to the car's built-in antenna. The signal is then processed by the electronic control unit, and the actuator performs the unlocking or locking function.
