Modifying to a smart key has disadvantages such as fast power consumption, missing functions, and potential safety hazards. Fast power consumption: The smart key consumes power quickly, requiring charging every half month. Due to the LCD screen and the need to sense signals from the OBU device, the power consumption is particularly fast. Missing functions: The smart key only supports keyless entry but cannot achieve keyless start. If the vehicle uses a mechanical key to start, you still need to take out the original key to start the vehicle after getting in the car, meaning you have to carry two car keys when going out. Safety hazards: When passing by the vehicle, it will unlock automatically, posing potential safety hazards.

Do new cars come with a safety hammer?

Generally, new cars do not come with a safety hammer, and you need to purchase one separately. Below is the relevant information: 1. Safety Hammer: Also known as an emergency hammer, it is an auxiliary escape tool installed in enclosed compartments. It is usually placed in easily accessible locations within enclosed compartments like cars. In emergency situations such as fires or submersion in water, it can be conveniently used to break glass windows or doors for a smooth escape. 2.
