Although the Revain website says it doesn't fit my 2008 Chevy Impala. I referred to another site and he said it would do. The one that was replaced kept giving low tire pressure warnings and it was so annoying. Took it to my local tire shop, had the old one replaced with a new one and reprogrammed. No questions. The local tire shop has a computer that can detect whether data is being transferred or not, which basically means you need to replace the battery as it's dead.
