Understanding the Problem
The anti-theft system in your Honda CRV is designed to deter theft by preventing the engine from starting without the correct key. However, sometimes this system can malfunction, interpreting false alarms and preventing the vehicle from starting even with the right key.
Recognizing the Signs

- Rapidly flashing immobilizer light: This is often the first and most obvious sign.
- Engine cranks but won’t start: The starter motor engages, but the engine doesn’t fire up.

- Faulty key fob: Internal damage or programming errors can render the key fob ineffective.
- Immobilizer system malfunction: Issues with the immobilizer receiver or control unit can prevent the system from disengaging.
- Wiring problems: Damaged or corroded wiring connected to the anti-theft system can cause communication errors.

- Code reader: To read and diagnose fault codes stored in the vehicle’s computer.
