Why don't the hazard lights flash when locking a 2006 Passat Lingyu?

The reasons why hazard lights don't flash when locking the car include: 1. The alarm switch under the front hood is not properly closed; 2. The car door is not properly closed; 3. The remote key fob battery is dead; 4. There is strong signal interference where the vehicle is parked, causing remote control failure. Preventive measures include: 1. For smart remote keys, avoid contact with strong magnetic fields such as high-voltage lines, transmission towers, and other places with strong magnetic signals; 2. Try not to drop or throw the smart key when using it. Hazard lights, also known as emergency flashers, are activated by pressing a red triangle button on the vehicle's dashboard. Their main purpose is to alert other vehicles in case of emergencies, and they should also be turned on when parking on the roadside to prevent rear-end collisions.
