If the key fob has no power, you can first use the mechanical key to pry open the decorative cover on the far right of the left front door handle, then use the mechanical key to open the door. Once inside the car, insert the key into the ignition switch to start the vehicle. Specific steps are as follows: 1. If the smart key battery is completely dead, you must replace the key battery before starting the vehicle. 2. First, eject the mechanical key, then position the key with the logo facing upwards. Next, insert a flat-head screwdriver into the mechanical key slot and rotate to loosen the key clasp. Apply force to both sides to pry open the back cover of the key, exposing the battery. Remove the old battery and install a new one to complete the battery replacement process.
That time when my Volkswagen car key ran out of battery, I almost panicked, but luckily there was a way to handle it. First, find the small button on the key, press it to release the mechanical key blade, then insert it into the lock cylinder on the driver's door handle, turn it, and the door will open. Once inside the car, don't panic: Volkswagen's keyless system has an emergency induction area, usually near the start button on the center console. Place the key fob against that area, press the start button firmly, and the car will start. This method works well—I've tried it several times, especially when the battery dies suddenly at night, which is the most annoying. The key is to keep the key close to the button and not too far away. Finally, remember to replace the battery promptly to avoid trouble next time. I recommend all owners familiarize themselves with their manual, as it has clear diagrams.
I'm the kind of person who enjoys delving into cars, and Volkswagen's key system is quite reliable. Even when the battery is depleted, the RFID chip inside the key can still function through electromagnetic induction. The operation method is straightforward: first, use the hidden mechanical key to open the door and get in the car; when starting, place the key against the designated induction point at the bottom of the steering wheel or on the center console—these locations are generally similar across most models. This technology relies on magnetic field scanning of the chip and doesn't require additional power. I've researched it, and Volkswagen models like the Polo or Tiguan are set up this way. If it doesn't sense the key, it might be due to chip misalignment or a car battery issue—I recommend testing it in advance. In daily use, I regularly check the key's voltage with a multimeter—preventive maintenance is crucial. Don't forget about the spare key; avoid always using the same one.
Don't panic if your key runs out of battery, Volkswagen has an emergency solution. When opening the door, use the mechanical button on the key to pop out the metal piece, insert it into the lock hole and turn to open the door. After getting in, press the key shell against the start button and push down to start the car. This is the most common method.
