If the Passat key is locked in the trunk, you can ask a family member to bring the spare key to open the trunk, or contact a professional locksmith to unlock it. Alternatively, you can visit a repair station to have a new key matched, which requires providing the vehicle registration, the owner's ID, the 17-digit key anti-theft code, and the metal key blade number. Below are some recommendations regarding car key usage: 1. Keep the spare key separate from the main key and avoid locking the spare key inside the car to prevent thieves from driving away if the main key is lost. 2. If the key is lost and there are valuables inside the car, consult your insurance company about the compensation process for vehicle theft and preserve evidence promptly. 3. If the car lacks an anti-theft system, consider installing a steering wheel lock to prevent theft in case the key is lost.

As a Passat owner, I've also experienced the key-locked-in-trunk situation. Back then, I had just parked and was about to go shopping when I hastily left the keys in the trunk and closed it—game over. I first tried checking if there was a hidden lock cylinder on the trunk lid, but my older model didn't have that feature. I had no choice but to call a local locksmith service; the technician arrived within minutes and gently popped it open with tools, costing me over a hundred yuan. After that, I learned to always carry a spare key as a precaution—otherwise, it's just wasted time and money. Now, whenever I open the trunk, I make a conscious effort to check that the keys are in my pocket. Developing this habit has saved me a lot of hassle.

The first time I drove a Passat, I made the mistake of locking the keys in the trunk and was as anxious as an ant on a hot pan. At first, I desperately tried to pry open the trunk lock, almost damaging the car paint. Luckily, a neighbor reminded me not to act recklessly. I had to look up the phone number of a nearby 4S dealership, and they sent someone to unlock it effortlessly. The whole process took just 20 minutes and cost me 150 yuan. The lesson was profound: when buying a car, it's essential to have two sets of keys—one to carry and one to keep in a safe place at home. A smart key app is also worth installing, but not all Passat models support this feature. If the car lacks this functionality, you’ll have to rely on traditional methods.

As someone who enjoys tinkering with cars, I've seen people manually pry open the trunk when they lock their keys inside, but this is risky. Not only could the Passat's door lock be damaged, but it could also leave scratches. For safety, I think it's best to contact a professional unlocking company or the dealership. They have special tools to handle it quickly. I suggest first checking inside the car or your bag for a spare key, or trying the remote control via a mobile app. The cost is usually around 100-200 yuan—not too expensive but ensures peace of mind. After driving for a long time, these little incidents remind us to be more careful with our keys.
