Hi there,
If your SUV starts but the security light is flashing, it indicates an issue with the vehicle theft security system (VTSS) or the sentry key immobilizer module (SKIM). Here are the other possible causes and solutions:
1. Key not recognized. If you are using a new, unprogrammed, or worn-out key, the system may not recognize it. Try using a different key if available.
2. Bad SKIM module (Senty Immobilizer Module). If the module is faulty, it may intermittently not recognize the correct key. Use a scan tool to check for SKIM-related trouble codes.
3. Failing or weak battery. A low/weak battery will cause the security system to malfunction.
4. Faulty wireless control module. If this part is bad, it will cause security issues. It may require dealership-level programming if replacement is needed.
5. Ignition switch issues. A faulty ignition switch can cause issues with the SKIM system.
I hope those details give you a headstart in troubleshooting and fixing the issues on your vehicle. Good day!
