There are several reasons for the malfunction of the Volkswagen car remote control unlock button. No response from the remote control: If the remote control indicator light does not light up or is very dim when pressing the button, it may be due to insufficient battery power in the remote control. If the indicator light still does not light up after replacing the battery, check whether the battery polarity is reversed and whether the battery has good contact with the installation seat. If the above checks show no issues, but the remote control indicator light still does not light up, check whether the button is damaged. If some buttons cause the indicator light to respond while others do not, it is likely that the buttons are damaged or the remote control itself is faulty. Remote control cannot operate the door: First, confirm whether the remote control has any issues as described above. If the remote control is functioning properly and the issue arises after replacing the battery or anti-theft system components, follow the fixed procedure to match the remote control. Note that not all vehicle models require matching, as different models have different regulations. If there are two remote controls, test whether the other remote control responds. If the other remote control works, it may be that the password for this remote control is lost and needs to be re-matched. If the remote control still does not work after matching, there may be an issue with the receiver host or the transmitting antenna of this remote control. If the remote control host is shielded or there is strong interference nearby, the host may not correctly receive the electromagnetic waves emitted by the remote control, making it unable to control the central door lock action.
