Mine was a bad BCM, if you go with a used one, make sure you match the VIN, and I would only pay $150 for it. If you want to go with new like I did,,, replace it,, go through the security bypass programming and then take it to a dealer to finish programming. I will add two links, one for the part, for $170 new OEM and the other for the security video.
