How to Restart After Replacing Car Key Battery?

[VanJudah]

To restart after replacing the car key battery, first start the vehicle's engine and activate the entire electronic system. Then, press and hold the lock button on the driver's side door for more than 5 seconds without releasing. The car's remote control will then complete the matching process. Below is an introduction to car keys: 1. Introduction: A car key is a tool used to switch the car on and off. Modern car keys use a chip system, which is a magnetic chip system. The car's ignition lock cylinder's reading coil will read the key's chip; each chip has fixed digital information. 2. Categories: A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. 3. Advantages: The biggest advantage is that, regardless of day or night, you do not need to locate the lock hole and can conveniently unlock and lock the car from a distance. A weak radio wave is emitted from the owner's vicinity, received by the car's antenna, and the signal code is identified by the electronic control unit (ECU). The system's actuator (motor or electromagnetic coil) then performs the lock/unlock action. The system mainly consists of two parts: a transmitter and a receiver.
