Mechanical Key Cannot Open the Car Door_58 Auto The reason why a mechanical key cannot open the car door may be that the car's door lock is broken or the internal mechanical device is damaged. If you find that the key seems to have no resistance when using the mechanical key to open the car door, it can basically be concluded that it is disengaged, which will cause the mechanical key to be ineffective. Some car models will enter an anti-theft locking state when the car is locked. Not only will the engine be locked, but the car's central control system will also be locked, which will prevent the mechanical key from opening the car door. Generally, the door lock mechanism of the car's central lock is secured by a mechanical latch. If the door is not locked, you only need to use the outside door handle to open the door. If there is an unlock button inside the car, you need to enter the car and start the ignition before the car will unlock.
