What is the reason why the car key cannot be pulled out and the engine cannot be turned off?

Car key cannot be pulled out and the engine cannot be turned off because some cars have an ignition protection interlock device. When the car's gear is not in P or N, the engine cannot be turned off, and the key cannot be pulled out. Precautions for using car keys are as follows: 1. Do not place it with electronic devices: Since smart keys use low-intensity radio waves, they may not work properly under magnetic interference. Frequently placing the smart car key together with a mobile phone will inevitably cause the smart car key to malfunction, because the chip in the smart key may sometimes be interfered with by the mobile phone frequency, which may temporarily disable the remote control function of the key. In addition, if the smart key receives high-intensity radio waves, it may excessively consume battery power. Therefore, do not place the smart key near electronic devices, such as TVs or personal computers. 2. Do not throw or drop it randomly: For smart keys, the most feared situation is being dropped from a height, because most smart key shells are relatively sturdy, while the internal circuits have weak impact resistance and are easily damaged under severe collisions. Moreover, if the smart car key gets wet, the internal circuits may burn out, also causing remote control failure. Therefore, if the smart car key gets wet, never shake the key vigorously, as this can easily cause water to flow to other important circuits. Also, do not use the remote control to unlock immediately, as this may cause the circuit board to burn out. The correct approach is to open the key shell, lay it flat, and dry it with a hair dryer, then take it to a repair shop for inspection. Additionally, avoid exposing the smart key to high-temperature direct sunlight environments, such as the dashboard or engine hood.
