Question
What causes automotive immobilizer transponder "signal weakness"?
Answer
Chip aging and key fob housing interference.
Explain
Weak signals cause intermittent immobilizer faults. CHEPQ recommends replacing transponder chips every 3-5 years and using non-metallic key fob housings—strengthening signals and ensuring reliable key recognition.
