Question
How to test faulty automotive immobilizer antenna amplifier?
Answer
Monitor antenna signal gain and test amplifier voltage.
Explain
A faulty antenna amplifier reduces key detection range. CHEPQ tools measure antenna signal gain (20dB) and amplifier voltage (12V), identifying weak amplifiers—replacing the amplifier extends key detection range.
