What Are the Reasons Why the Remote Car Lock Doesn't Work?
1 Answers
Remote key fob failure to lock the car can be due to a dead battery or poor battery contact, malfunction of the time control module in the remote key, or aging of the car's remote transmitter antenna. Below is an introduction to the remote key fob: Remote Key Fob Functions: A remote key fob utilizes the wireless remote control function of the central locking system, allowing doors to be opened or locked from a distance without inserting the key into the lock. Once activated, the key fob analyzes the authentication signal sent by the car and transmits a corresponding encrypted signal to enhance security. How Remote Key Fobs Work: The key fob first emits a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator (either a motor or electromagnetic coil) performs the locking or unlocking action.
