Hi there. Thank you for using our service.

Sounds like it could be the immobilizer feature of the anti-theft system has been triggered. Is the anti-theft warning light on the cluster? Are you using the correct transponder key?

Customer: replied 1 year ago.
The anti theft light is not on when the key is turned to the on position...And, I am using the only key on the key ring...I tried to manually lock and unlock the doors via the outside key lock. That didn't help at all.
Expert:  Juan Crespo replied 1 year ago.

By "the only key in the ring", do you mean it is the correct transponder key? Are there any of the original remote fobs available?

Customer: replied 1 year ago.
I found the problem...It turned out to be a wire corroded off of the relay box under the hood...The wire fed the main relay...Fixed it and it runs good now.
