Hi!Hi. I know this is a really post, but I'm having a similar issue. My one key fob was behaving badly a few weeks ago and I bought batteries. When I got back to the car, the remote was working, so I left it. Then today, it did the same thing so I put new batteries in it. It is still doing the same intermittent thing. I tried re-sync as above, but that didn't help. It's completely random when it decides to work. Any other ideas?
