Why does the car remote have power but not work?

[MadisonRose]

When a car remote has power but fails to function, it is usually due to damage in either the transmitter of the car key or the receiver. The best way to check if the transmitter is faulty is to use the spare key. If the spare key can start the car, it indicates that the transmitter of the original key is defective. Below is relevant information about car keys: 1. Types of car keys: Common car keys are generally divided into three types: the oldest purely mechanical keys, remote + mechanical keys, and chip keys. 2. Documents required for key configuration: When getting a key duplicated, you need to bring your driver's license, vehicle registration certificate, and the motor vehicle registration certificate. For different grades of vehicles, the prices naturally vary, and the differences can be significant.
