How does the locking system work?
Modern cars have up to 4-5 different mechanisms of unlocking. Given that the door will be opening and closing thousands of time throughout the car’s service, the mechanism should be quite reliable. Nevertheless, errors and breakages happen. There are at least 6 ways of unlocking a car door:
- simply using a key;
- using the combination lock;
- pressing the unlock button;
- pulling up the knob;
- using a remote control;
- the signal from the body controller.
Although modern locking systems may seem really complicated, they can be explained easily. The main computer in your car, called the body controller, makes all decisions regarding locking and unlocking the doors. It is designed to make a car more user-friendly and comfortable. The mechanical part is even simpler: the knob and actuator are connected by a rod inside the door. So often times, all you need is a long metal strip with a hook to fish for this rod and unlock the car with a simple vertical motion.
