What is the reason for the anti-theft light staying on but the car can still start?

[DelLena]

The anti-theft light staying on but the car can still start may be due to a fault in the anti-theft device. The specific reasons are as follows: Short remote control distance: Troubleshooting method: First, check if the receiving antenna is functioning properly, if the 12V battery in the remote is too low, and observe for any surrounding magnetic interference; extend the anti-theft host antenna and keep it away from the system host; Remote control failure: Troubleshooting method: Check if the host is powered; if the central locking is functioning normally; inspect the 12V battery in the remote; check if the alarm is active (the remote may not deactivate during an alarm, wait until the alarm ends to deactivate); Blown fuse: Troubleshooting method: Check if the wiring is correct; inspect if the ribbon cable connection is proper; ensure the positive and negative terminals are not reversed; verify if the power supply voltage is normal (12V power supply).
