Why Does the Remote Key Fail After Replacing the Car Battery?
1 Answers
Car remote key failure after replacing the battery may be due to aging internal circuits in the key. The specific reasons are as follows: 1. The remote key fails and needs to be re-matched after replacing the car battery. This requires reconnecting the relevant systems in the car. Insert the key, turn it to the "II" position, and then quickly reset it to the "0" position. 2. The car's remote key does not emit an infrared signal. It is highly likely due to aging internal circuits. 3. The car's inspection system cannot recognize the smart card. It may be due to a malfunction in the remote key's internal module.
