There are several methods to open a car when the key is left inside: 1. Use a sharp object to remove the door seal and insert a wire through the gap to press the unlock button; 2. Call the 4S store's after-sales rescue hotline; 3. Use a spare key; 4. Contact a qualified and professional locksmith company; 5. Use adhesive tape to stick to the car window and forcibly pull it open. The working principle of a car key is: it emits a weak radio wave from the owner, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator performs the locking or unlocking action. Car keys are categorized by usage into: 1. Active working mode; 2. Passive working mode; 3. Coil induction mode.
