What is the reason for the Haima M5's anti-theft light flashing but the car not starting?

[Trenton]

Haima M5's anti-theft light flashing but the car not starting is due to the anti-theft chip in the key or the receiving antenna on the keyhole falling off. The following is a specific introduction to the car's anti-theft system: 1. Anti-theft authentication: For vehicles with a keyless system, press the unlock button or the keyless button on the driver's side door handle to open the door and deactivate the vehicle's alert status. Switch the power to the ON state, and if the engine's anti-theft authentication is successful, the anti-theft indicator light on the dashboard will turn off. 2. Automatic locking: After unlocking, if any door, window, or ignition switch is not opened within 30 seconds, the doors will automatically lock and re-enter the alert status.
