Where to Replace a Broken Car Key Button?
1 Answers
There are generally two methods to replace a car key: one is to go directly to a car 4S store, and the other is to go to an auto parts market. Below is some relevant information about car keys: 1. Main functions: In addition to controlling the opening and closing of car doors, car keys can also control the opening and closing of windows and the trunk. 2. Working principle: When the owner presses the button on the key, the key emits a signal. The signal contains corresponding command information. The car's antenna receives the radio wave signal, and after authentication by the Body Control Module (BCM), the actuator performs the locking/unlocking action.
