Why Won't the Central Lock Pop Open?

[SanAnderson]

Reasons why the car door lock switch won't pop up: 1. The lock cylinder drive rod has come off. 2. The door latch mechanism is faulty, either the internal spring is broken or stuck and not moving smoothly. Here is some relevant information: 1. If the door latch doesn't spring back, it may be due to misalignment of the latch position. You'll need to adjust the positional relationship between the latch and the striker. You can use a tool like a screwdriver to gently pry the latch, then close the door to test the adjustment until it fits properly. 2. Rust on the lock hook can also prevent the door latch from springing back. You can purchase a bottle of rust remover or grease to remove the rust, applying it evenly on the door lock hook and latch, then repeatedly opening and closing the door to distribute the lubricant evenly. Additionally, if the door lock hook is tilted, you'll need to adjust the entire door.
