The service engine light and the security light turned on?

Hi,

If the anti-theft/security light is on and stays on when you try to start it, try a different key. The key itself may have been damaged or failing.

Next, since the check engine light stays on when the engine is running, there are diagnostic trouble codes stored in the computer.

Here is a link that explains how to retrieve codes:

If you don't have or have access to a scan tool, most parts stores will scan it free of charge. Have that done and let me know what codes are found.

Take care,

Joe

It's not the check engine light it's the service light I just had oil changed and it came back on 3 days later when the anti-theft light came on.

Hi,

If the service light comes on for something like an oil change, do this. Turn the key from off to the run position (engine off). Within five seconds, press and release the gas pedal three times. Count to 5 after you release the pedal for the third time and turn the key off.

The service light should be off.

Next, to determine if there is an issue with the anti-theft, turn the key to the run position (engine off) and allow it to stay on for approximately ten minutes. See if the light then turns off.

Let me know what you find.
