Hi Lori. Give this a try and see if the security light goes out.
Make sure the battery if fully charged because this procedure may take up to 30 minutes and you cannot start the vehicle during this time. The BCM and PCM must be in working order and the Passkey system repaired
1. Turn the key to "on", but do not start the vehicle. Leave the key "on" for 11 minutes. The security light should be on steady or flashing during the entire 11 minutes. Do not proceed to the next step until the security light either turns "off" or "stops" FLASHING.
2. Turn the key to "off" for 30 seconds.
3. Turn the key to "on" for 11 minutes, just as in Step 1.
4. Turn the key to "off" for 30 seconds.
5. Turn the key to "on" for 11 minutes. This will be the 3rd time you’re doing this.
6. Turn the key to "off" for 30 seconds (yes, this is the 3rd time you’re doing this too).
7. Turn the key to "on" for 30 seconds.
8. Turn the key to "off".
9. Start the engine.
Rich.
