FAQ Answer

Question

When should I replace vehicle controller hardware due to immobilizer issues?

Answer

Replace hardware when you experience recurring freezes or immobilizer failures on the same unit after firmware updates fail to resolve it. Also replace if an entire batch shows issues, or if your devices lack critical features like dual-SIM failover for reliable command reception, which is necessary for dependable remote immobilizer function.
