What is the reason why the Passat door lock cannot be opened from inside or outside?

It may be due to the child lock being activated. Here is some relevant information: 1. Exterior: The new Passat is built on the MQB platform, with an overall design that is more imposing compared to the Magotan. The front grille is larger in size, and the body length is close to 5 meters. It also features a fastback design, making the car appear more elongated. The LED taillights at the rear are the finishing touch, with outstanding display effects. Additionally, it uses a lot of horizontal and straight lines to create a coupe-like feel. 2. Interior: The new Passat offers a brand-new experience. The full LCD instrument panel has three styles that can be freely switched, with complete functionality and a strong sense of technology.

After repairing cars for so many years, I've encountered quite a few cases where the Passat door locks couldn't be opened from inside or outside. Most of them were due to mechanical component issues, such as a jammed locking mechanism or a detached linkage rod. Volkswagen's door design is relatively compact, and older Passat models are prone to poor opening/closing due to insufficient lubrication, dust accumulation, or slight deformation of the door frame. You might want to try spraying some lubricant on the door hinges first. If that doesn't work, then you'll need to remove the interior trim panel to check if the internal connections are intact. Sometimes, door impacts or long-term lack of maintenance can also cause these troubles. Don't wait until it becomes a major issue to address it, as it could not only delay your trip but also increase repair costs. Applying some anti-rust lubricant during regular maintenance can effectively prevent such failures.

As a frequent driver of the Passat, I've also encountered situations where the door locks wouldn't open, both from inside and outside, which can be quite frustrating. I suspect this might be due to the child safety lock being accidentally activated—that small switch on the door edge is prone to accidental operation—or a chain reaction caused by a depleted key fob battery. For safety, I'd recommend immediately parking the car in a safe spot and checking the relevant fuses under the hood, but avoid forcing the door open to prevent further damage. Now, I make it a habit to briefly check the door and lock functions before each refueling, and I'm extra cautious before long trips.

When encountering a situation where the Passat door lock won't open, it's important to consider daily usage details such as common causes like door handle wear or loose connecting cables. When I faced a similar issue, I took some time to remove the door panel and found excessive dust accumulation inside - a simple cleaning restored normal function. It could also be a temporary electronic system glitch; restarting the vehicle sometimes provides an immediate solution. In any case, don't panic immediately - methodically troubleshoot starting with the simplest possibilities.
