But the anti-theft performance is very poor, which is basically equal to no anti-theft. Because whether the original car is started manually or with one button, there is a chip in the key, and the chip senses the engine computer. Only the original car has it. The content you installed is not available. The burglar alarm only works when it is started with one button, but it doesn't work on the original engine.
Simply put, the original car key is anti-theft and the car is pried. As long as there is no key, the engine will be locked and no wiring can be started. The added one will remove the built-in chip of the engine lock. As long as it can get into the car, it will definitely drive away.
