What is the reason for no signal in the Trumpchi GA5 key receiver?
1 Answers
Reasons for no signal in the Trumpchi GA5 key receiver: 1. Car remote key battery is dead: The remote key emits weak radio waves, which are received by the car antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator performs the lock/unlock action. As the battery power decreases, the strength of the radio waves is also affected, resulting in the vehicle being unable to receive the signal. Solution: Replace the battery. 2. Faulty car key sensor module: Modern car keys use chips, which are part of a magnetic chip system. If damaged, the key cannot emit signals. Solution: Replace the key.
