What does car key upgrade mean?
1 Answers
Key upgrade only refers to software upgrade, the hardware remains the original car key. Below are the relevant introductions: 1. Mechanical keys: Currently, car keys are divided into two types, one without an anti-theft chip and another with an anti-theft chip. Keys without anti-theft chips are commonly found in some low-end car models, and they don't even have a remote control, which is now quite rare. Since they are mechanical keys without anti-theft chips or remote controls, duplicating this type of key is very convenient and quick. 2. Anti-theft keys: Keys with anti-theft chips are naturally much more advanced. Besides the mechanical part of the key needing to match, the key also needs to be reprogrammed so that the code of the key chip completely matches the code of the engine's anti-theft system to start the engine.
