- The chip in your key may be damaged or not programmed correctly.
- The ignition switch may not be properly installed.
- There may be a problem with the wiring between the ignition switch and the security module.
To troubleshoot the issue, you should first try reprogramming the key chip. You can do this by following the instructions in the owner's manual. If the key chip does not reprogram, or if you do not have an owner's manual, you will need to take the car to a dealer or qualified mechanic to have the key chip programmed.
If reprogramming the key chip does not fix the problem, you will need to check the installation of the ignition switch. Make sure that the switch is properly connected to the wiring harness and that the mounting screws are tight. If the switch is not properly installed, it could cause the security light to come on.
If the ignition switch is properly installed, you will need to check the wiring between the switch and the security module. The wiring harness may be damaged or loose, which could cause the security light to come on. If the wires are damaged or loose, you will need to repair or replace them.
If you are unable to fix the problem yourself, you will need to take the car to a dealer or qualified mechanic to have it repaired.
