What are the reasons for the insensitivity of Volkswagen's keyless entry?

Volkswagen's keyless entry may be insensitive due to a possible malfunction in the circuit board of the smart key, causing the sensing system to have no feedback. If the issue cannot be resolved immediately, you can first use the backup function on the smart key to open the door and use the vehicle, and then proceed to a 4S store for inspection and repair. Presence of electromagnetic interference nearby: Signal interference sources, such as near cameras, telecommunication towers, high-voltage power lines, etc., can generate such interference signals, which may prevent the car from detecting the key. Smart key in a low battery state: This can also cause the starting system to fail to detect the weak radio waves emitted by the key. In this case, even when the key is inside the car, the dashboard may still display 'key matching error.'
I've been driving a Volkswagen for many years and have encountered situations where the keyless entry was not responsive. A common reason is low battery power in the car key; usually, when the key has been used for a long time, the battery drains and the signal weakens. Replacing it with a new battery can solve the problem. External interference is also crucial; for example, in parking lots or near elevators where mobile signals are strong, the system can be affected—try avoiding these areas. Another point is dirty sensors; dust or water marks on the door handle's sensing area can lead to poor responsiveness, and simply wiping it clean may restore normal function. Software issues cannot be ruled out either; the system occasionally needs a reset or update. I usually restart the key fob or refresh it via the car's infotainment system. If all simple methods fail, it might be an internal wiring fault—don’t hesitate to take it to a repair shop immediately to avoid long-term inconvenience affecting your driving experience.
As a frequent car user, I believe the sluggishness of Volkswagen's keyless system is mostly caused by insufficient battery power or electronic interference. When the battery is low, the signal weakens, and I've experienced immediate improvement after replacing it with an original battery. Interference sources are common: operating near mobile phones, routers, or large appliances can cause malfunctions, which are resolved by moving away. In terms of system settings, poor software compatibility can also trigger issues, so I often update the car's firmware to prevent problems. Location factors are crucial too: standing in front of metal objects like railings can block signals and slow down responses. Environmental humidity or high temperatures also have an impact, requiring patience during rainy or scorching conditions. Regularly testing the key's status can prevent embarrassing situations, such as checking indicator lights to confirm normal functionality—small habits that make a difference.
